Guys, this is not me talking…. think of this are your brakes being able to type with 2 fingers talking to you!
No, I’m not going to write like I’m a brake shoe….it would get too complicated but if youe coach COULD talk I think it (he/she) would want you to listen to this:
I have seen GMC’s roll in broken….but still moving. I can’t tell you all of them but one guy used 4 quarts of oil bringing me a coach to survey from Tampa! On and On but lets talk about read brakes…… specifically those on a long time GMC enthusiast who sold his beauty to it’s next steward. Knowing it had been fretted over for decades before, it was hard to say “just look at it all” because you wanna believe all you see and feel is true…I get that In reviewing the “punch list” in grease pen on the window I saw there was nothing about looking into the rear brakes. We were scheduled to install our new 2 wheel E brake system so we would already be in the drums…here is what we found…. now remember, nothing got on the to do list because discussing everything we all felt at least for now we would call that project 2. The black on my finger is brake dust stuck to everything by brake fluid. Sorry, couldn’t find the pic but trust me it was covered….. zoom in on that last pic. So my dynamic duo of Katlyn & Phillip started at the rear brakes Katlyn, the careful one goes in to chemically wash the brake plates
She’s using this hot shot German Wuurth aerosol parts cleaner emptying in the plastic bucket below. A nasty job you wear gloves and a mask After that, she’s grinding the big stuff the chemical wouldn’t budge! Like I said, nasty work, that wheel cylinder had to be seeping for years! The shoes were different…1 was rivieted as correct but the other one was bigger and bonded…not riveted which is a no-no……..walked in this morning to find this…… new everything and ready…2 wheeled Ebrake system installed. Hey, that’s how they work! Sorry guys but you just can’t trust a 40 year old spring to stop your 12,000 pound projectile!
The lesson here Padawan is: If you do no first person know the condition of your rear brake system….go have something looked at and expect to put in all new stuff!
BTW, we’re also installing a quad bag system with all that rear wheel work. Gonna leave the Bilsteins….they’re not leaking and the eyelets are only partially bad. The brake hose is not Teflon lined but it is not original but a replacement….see the hard thing isn’t figuring out what to do but where to stop!
OK guys, gotta go…see you tomorrow in our neighborhood…….
