How to STOP BRAKE SQUEAKING in your car (No Squeaks Guaranteed)

hey guys how's it going today I'm going to show you the top 5 reasons why your brakes are making noise brake noise is something very common in cars and it is easily one of the most annoying things you hear any driving so if your brakes are making noise it tells you that something in your brakes may need some attention now you might only hear the brake noise as you step on the brake pedal but sometimes it could be continuous so in this video I'm gonna take you through the four most common reasons for your brakes make noise and also what you need to know ignorant of the noise now that's enough talking let's begin so in your car the wheels attached to something all over your hub another thing that I should the bill happy is the brake rotor so when you draw the Caddy's breaker is also spinning along with the wheel then there's a brake caliper bracket this goes over the brake rotor unlike the brake rotor your caliper bracket doesn't spin then you have your brake caliper this caliper get bolted onto the cotter bracket using something called guide pins this caliper has to guide pins this flares the calculus slide back and forth as you apply the brakes inside the caliper you have the caliper piston now this is a very basic hydraulic piston when you step on the brake pedal are you actually doing is compressing a small hydraulic piston near the brake pedal and by doing that you're creating enough hydraulic pressure to move this brake caliper piston then we had the brake pads these brake pads get installed onto the car bracket anyhow the brake hell because of the brake pads so many apply brakes this brake caliper pushers the brake pads against the rotor this causes a lot of friction and that's how the cast was there and that is all there Stewart so now we know how the brakes Unocal work so let's get to the brake noise basically there are two types of brake noise brakes squeaking and brake grinding today I'm working on a 2007 Toyota Orion and I'm getting ready to do a complete break job because in this cut both front brakes the making noise the front left brakes are making a squeaking noise like this and the front-right brakes are making a grinding noise like this and the brake system in this guy is similar to the brake system in any other car so this is the perfect opportunity to show you guys the reasons for your brakes make noise let's start with the brakes squeak the number one reason why your brakes are making noise is the worn out brake pads just to show you the difference between a new pad and a worn-out one here we had the old brake pairs along with two replacement brake pads we have a genuine brake pad and also a cheap after-market brake pad now in this new brake pad you can see here he had the backing plate and then on top of the backing plate we had the brake pad friction material or sometimes called as fed lining and if you look at the end of the brake pad here we have both ends tapered down at an angle most new brake pads comes like this this is called the brake pad chamfered when the Cal go begin to push the brake pads against the rotor the brake pads begin to vibrate at high frequency this high frequency vibration is what pts brakes squeak if the brake pad has a straight edge then these frequencies can be much higher so the squeak is gonna be much louder by having this chamfers the brake pad now has a softer contact pressure against erotic so he can have radius brake noise but I asked the brake pad wears down he can see the friction material finally comes to a point where it no longer has any chamfer this is the time he normally stutter he brakes squeak as he step on the brake pedal along with this chamfers another feature comes with your brake pads is the wear indicators these steel Clips right here this is your way indicators so I have this very inexpensive brake pad thickness gauge and if you mention the thickness of this brand new brake pad we have 12 millimeters of friction material but as the friction material wears down to the two millimeters which is the minimum thickness of any brake pad these weigh indicators can screech against error and make squeak in to let you know that the brake pads are worn out but in high-end cast they don't have these two clips instead they have brake pad wear sensors so you wouldn't see this way indicators in high-end brake pads and also in very cheap brake pads have your brake pads can still make noise even if they are not worn out and that brings us for the reason number two why your brakes make noise which is very cheap work quality brake pads brake pads are made of different materials such as Jannik semi-metallic and ceramic and those different materials have different properties so they are used in different applications such as belly driving and racing for example many modern cars comes with ceramic brake pads and they are usually more expensive to replace so most people go for cheap replacement brake pads when doing a brake job but using a non ceramic brake pads in a car that is designed to a ceramic brake question is make your brakes start to squeak whether you're using ceramic brake pads or organic brake pads any good quality brake pad comes with something called anyway brush and shims bonded onto the backing plate you can say in this brake pad we have a nice fiber reinforced and it's quick shim molded onto the backing plate this goes in between the brake pad and brake caliper to absorb any vibrations and their batteries in the brake noise but in this cheap brake but it is just a piece of steel has in place by two rivets which may not work as get over the time and there is nothing compare this brake pad where it doesn't have a shim arrow the next thing you know look at is where this brake pad is can go in your brake caliper bracket and that brings us to the third reason why your brakes make noise which is the one at brake hardware in your brake caliper bracket right where the brake pad get installed you can see these steel clips this is your brake hardware this allows the brake pad to slide in and out smoothly as you apply the brakes but as your brake pads wear out so do these brake hardware and worn out brake hardware can create too much play between the brake pads and brake and the bracket allowing the brake pads to vibrate too much and that can make rake noise when you buy cheap brake pads they comes with will just the brake pads but when you buy some quality brake pads they comes with this brake hardware so any install new brake pads he always install new brake hardware so he brake system acts like it is brand new also your brake system is prone to collect a lot of brake dust moisture and dirt so with that proper lubrication your brake pads might get stuck to the brake hardware when you press the brake pedal the brake pads can take the rotor we already know that but as you let go of the pedal the brake pads come off the Reuter ever so slightly so that your brake pads barely not touching the rotor so if the brake pads are stuck to the brake hardware then they're not gonna come off the order instead they keep rubbing against the road all the time which can easily make a continuous break squeak when the brake pads are rubbing against the rotors the friction material gets very hard and the contact area start to glaze this might make you brakes very noisy and the worst of all glazing can lower the coefficient of friction on the friction material so you can might even lose someone stopping power and that is pretty bad glazing can also have been due to heart breaking as well often times you can easily identify anyplace in just by having a good look at your orders even look for any shiniest sports than the rest of the order and if you found any even a good medium grit sandpaper and lightly scratch the area in a circular motion glazing can also happen in brake pads as well so you're gonna do the same with the brake pads with the sandpaper this will even remove any contaminants that might be sitting on the brake pads not on with the brake pads but sometimes the brake caliper can get stuck and that brings us for the reason number four wire brakes make noise which is lack of lubrication oftentimes when people replace the brake pads they just lift up the caliper install the brake pads and that's it in order to keep your brakes working properly this brake caliper is supposed to slide in and out very easily and that job is done by these two guide pins and that's why these guide pins need lubrication to get to the guide pins first you remove the two bolts that hold the caliper and these are your guide pins to protect the guide pins from getting corroded and contaminated by dirt and moisture we have these rubber boots sitting or the guide pins but over the time the rubber seals may become weak so the date can get into the guide pins and the brake caliper can get stuck in place when the brake caliper gets stuck so do your brake pads so the brake pads start rubbing against the rotor all the time which can easily make will you guess it a continuous brakes squeak so to stop this from happening even apply a decent amount of lubricant to both guide pins and also on the brake hardware where the brake pads get installed because the brakes are working at higher pressures and higher temperatures it is very important to use the right lubricant on your brakes to see which lubricant works the best for yoga he can always have a look at the service menu now when you buy some quality brake pads he also get 20 volts for these guide pins with pre applied thread Locker so this boats wouldn't back out as you drive so now you can realize that you can easily fix brake noise just by using some good quality brake pads the biggest problem with this cheap break pants is that sometimes they have uneven material distribution throughout the brake pad so in these brake pads rubbing against your orders as you press the brakes your order is also gonna start to wear unevenly speaking about the rotors the reason number 5 wire brakes make noise is too worn out brake rotors as you brake pads wear out so do these brake rotors you can see in this rotor this lot of grooves carved into the rotor which is gonna create an uneven surface between the brake pads and the rotor probably because of the use of cheap brake pads now this can also happen if you drive off-road because the date and sand can get in between the brake pads and the brake rotor speaking about offroad any time you drive off-road there's a chance your orders get hit by rocks and get worked or sometimes even these dust covers can get bent and start scratching against the rotor this can easily create a continuous already make brake noise now even if you install brand new brake pads for this rotor the new brake pad still gonna grab onto these grooves as you apply the brakes so so it'll start to make noise again so in this case you know resurface the road before you install new brake pads in my case I decided to go with brand new brake rotors speaking about brand new brake rotors most brake rotors submit of cast iron because cast iron has good heat dissipation properties and also good friction properties but the biggest issue with the cast iron is that they tend to rust over the time this is not a concern for a car that is driven on a daily basis but a big concern for cast that are not driven too often because over the time the rust can build up to a pretty decent am and so as he pressed the brakes this layer of rust gets sandwiched between the brake pads and the rotor and this could easily make brake noise alright now it is time to mourn to the worst brake noise of them all which is brake grinding if we hear a grinding noise from your brakes that indicates something in your brake system is seriously one at two dangerous level so you definitely want to take a look at your brakes before it's too late now that's what I'm talking about this inside brake pad is so odd that this is just a backing plate here's another thing you need to know because this inside brake pad is in direct contact with the brake caliper piston all the time this brake pad is always the first to be in contact with the rod as you press the brakes so it is very common for the inside brake pad to help move air on it then the outside brake pad that is why whenever you replace brake pads you always wanna install the brake pad with the way indicator to the inboard side not to the outboard side also you can see right away the brake pad sit on the rudder there's two ridges now if you can't install new brake pads on this Roddick then the brake pad will hit these ridges and will start to squeak so before you install the new brake pads it is a good idea to use a sandpaper to smooth out these ridges but in my case I'm replacing both brake pads and also the rotors so that is something I don't have to worry about and that takes us from the rear brakes brake noise can come from your front brakes or from your rear brakes now in this car the rear brakes also these brakes just like the front brakes so everything we discussed so if I apply to these brakes as well but in some cars like this master the front brakes are disc brakes but the rear brakes are drum brakes now in this drum brakes instead of brake pads we have brake shoes p0 brake rotor we have a brake drum instead of a brake type of piston we have a wheel cylinder so as you apply the brakes this wheel cylinder pushes the brake shoes out clubbing the brake shoes to squeeze against the brake drum this creates a lot of friction which slows the car down so this is a slightly different setup to the disc brakes but still the same principles apply in terms of how it works so just like in this brakes Monad brake shears poor-quality brake shoes worn out brake hardware lack of lubrication and last but not least worn out brake drums can make brake noise I like in this brakes where the brake dust from brake pads can fly your finger air drum brakes are in closed systems so most of the time the brake dust is collected inside the brake drum so this brake dust can get in between the brake drum and the brake shoes and this can make brake noise as you apply the brakes so sometimes you can easily stop your brake noise just by cleaning your brakes speaking about the cleaning only is a brake cleaner menifee clean brake pads because this stuff is designed to use in brakes since we are talking about drum brakes I have one last thing which is often the most forgotten part in any brake system which is the emergency brakes this can be your hand brakes foot brakes or even electronic parking brake and all these places lock up the rear wheels now even if your car has rear disc brakes most of the time you still have drum brakes for the emergency brakes hiding behind your brake rotors so you make sure nothing is worn out or rubbing against each other which can make brake noise and that wraps up my top 5 reasons why your brakes make noise so go check out your brakes before it's too late also if you don't learn how to replace your brakes then check out my video on Harold place your brake pads
