Truck project update: Brake Time! Assembling drum brakes on our 1950 Chevy 3600 | Redline Update #33

hey this is Damon with Hagerty and a redline rebuild series we are back on a 1950 Chevy pickup truck last time we went through and reassembled the transmission and the rear differential and now we're on to the rear drum brakes and subsequently the front drum brakes but today I thought I walked through real quick just kind of some bits and pieces now we did do a very detailed drum break how do they work type function on our 1969 Camaro go ahead and refer to that over here but here I'm going to show you a couple little differences between the more modern 60s brakes and these 50s brakes now on the modern brakes you have their self adjusting on the little older ones they're non self adjusting meaning when you backup or apply the park brake they do not self adjust for wear meaning taking up the gap relative to the shoe to the drum on these you have to actually manually go in and part of the maintenance routine would be to self or not self adjust manually adjust the brake cylinders so the that brake is taken up and you have a nice firm pedal so just general components here on this one you know in a grand scheme of things everything works off a pivot in a push so you have a fixed pivot on these particular parts down here in the center and then you have your push which is your master cylinder and that pushes these pads out this is the park brake assembly it does basically the same thing it has a cable though that pulls and as it pulls it pushes out or transfers out and pushes out the shoes to to hit the drums now this has a little bit more claptrap to it than some so unless you have they basically made an extension off of the shoe it must have been cheaper to stamp out a bunch of these other extra pieces and clamp them instead of having a in having one common shoe then you have these that these will clamp together and then you have one main pivot pin here that goes through subsequent list goes over to the other side now one thing I ran into with this so I've all I've done from restoration standpoint I had to have my shoes realigned so I sent these down had had them relined as far as new linings onto the old core which was pretty typical in the day and and then I got I had my I just took my these pieces I don't want to call these extensions I guess I just sandblasted them and shot some paint on them so instead of looking like this now they look like this just kind of clean things up I want to make sure all my pivot points are good and then another thing I ran into as a slight snag are these are the stock clips you can see in both these two pin styles of pins they have this undercut in here or a groove and then this would slide in and lock in place and not allow the pin that just slide out problem being is they don't manufacture these any longer so I had to come up with a slightly different idea and what I looked decided was this more common 60s horseshoe clip will be perfect here you slide it on pitch it together that'll solve the problem with a smaller pin now when I got to the bigger one the issue I had was finding a c-clip that would go on here that was the right size now ironically this is of course all English or standard dimensions meaning it's either a 3/4 or a 5/8 well it's actually neither and a number fifth or a 15 millimeter eclip that's the best now my point to all this is think outside the box sometimes you need to be a little more creative as far as well the catalog doesn't show me my part well so what I understand what the function is and and figure out a way to get around it if you can't get the part or worst case you could always make a couple of things I kicked around was actually drilling in pinning this and some things like that would have worked everything would have been fine but again keep it safe obviously but there's some other options out there just be a little creative with it now I'm gonna go ahead and just get this all assembled we'll walk I'll just show you it being done I'm going to use two kinds of lubricants here I'm just going to use some anti-seize on anything that is a fixed part so in other words it doesn't have to pivot not that it wouldn't work on the pivots but I have some thermal lube for brakes that I'm going to use as far as like on the main pivot and up here in this area and then in the slides on the on the vehicle so anyhow that's what that's what we're gonna do so with that I got to get my hands dirty [Applause] [Applause] well I think gonna work kind of a little trick here I took a pair of these GP tool shops see clamp style vise grips welded this pad so it doesn't pivot just so it doesn't fight me for other reasons and then I took the pad off the other side had a what ultimately is a 14 millimeter wrench a nasty one laying around old one and welded it on here such that now get it lined up on the back so you're pushing the pin up you got a straddle this spring just enough clamp the pliers down and now you can see I have room for the clip to come in here you may have to use a screwdriver to kind of coax it a little bit okay so now you can see it's it's in that groove and gently pull it up but I don't want to pop out of course just my slip joints not bad Hey [Music] all right so we have our front brakes now assembled as far as all the little extra leverage arms and spring and that's in there and fit kind of learn a little lesson from the backside as far as getting things a little more situated out here than struggling with it back there as much but anyhow front brakes are ready to go on back brakes are done I'm gonna wait though on the front brakes and let me show you why because hey I need to replace the leaf spring the other side is broke this one was broke I have some brand new leaf springs and all the stuff from lMC to attach them so I'm gonna wait on that because I want to have any extra mass than I have to with this here and my kingpin is pretty well shot so we're gonna fix that while we're here I'm gonna put a brand new set of shocks on as well but we're gonna move back to the back end instead and put new shocks on it and eliminate that extra helper leaf spring [Music] that's definitely a flavor you wouldn't have in sense [Music] well we got the shotguns overs out there are cut laying on the floor but I got a little more work than I expected the upper mounts are bad so they're gonna have to cut off and put some new ones of those on and the shackles the bushings are completely whopped so we need to order some parts but that's the end of the day no big deal while you're waiting for us to get parts click and subscribe we got more videos to come obviously because this truck isn't done and we have other projects so hey we'll see you around
