Hey first I need to explain something… yesterdays post was done late at night on a cell phone. I made a southern colloquial expression “Me.. Myers” Oops… O consulted the southern draw primer … that’s ME.. My..ers not me..Myers. Heck, that’s sounds like a guys name I really like… Sorry bout that brother Hey, he’s from the north, I need to cut off the draw when I’m ranting…. sorry man. Man, you’re not a Me.. My.. er at all!
I hope we have caught this threat and secured the site before the shit hits the fan …. have no fear, I have some savy GMC owner friends who are helping us so stay watching like I said. I’m not going to blurt anything out unless there becomes an issue so lets just act like there are no bad guys and believe all is OK… I’m ready though…
lets ge out of ll this crap and get back to the fun of this. After all THAT’s why we’re here.
Had an interesting lesson perpetrated upon us by our parts supplier. Brake shoes… if they were the correct ones and riveted liners we all have said hey “a 462RR shoe set is a 462RR shoe set”… right? No fancy harder than woodpecker lips abrasives used just straight $28 for a set for 2 wheels… right? Well, my supplier had run out of my exact part we always have him stock for us so he went over to Car Quest and picked up one set for me there. Hey, I didn;t see a big deal with it, I always use basic, inexpensive shoes and explain I would rather change shoes than buy an expensive new drum. Well, we put the shoes on and the test drive reveiled a 100 degree hotter side with the Car Quest shoes installed. Of course we didn’t connect the dots right away. We checked installation and adjustment 9 ways to Sunday… no difference (235+ degrees with 125 on the pass side). I had Hank replace the cross steel line in the back which would be the only part that both sides would not share. As it turned out is WAS flowing freely but fell apart when we went to remove it.
In desperation, John D. had asked the question at last weekends SS rally for kicks…. the suggestion was they were put on backwards…. well, I’l look at anything. We pulled the drums all off again and the only thing we could find different was the the shoes on the hot side had black colored liners with the other side the usual grey color we see. Wait… wait… what’s that about. Called the supplier and order up 2 exact sets of our usual shoes… put them on, adjusted and the test drive—– @ 150 all the way around! Well looke there and the double/check bonus is before we would hit the brakes hard and the rear wheels were skidding… both sides. Now, sinchine the seat up all 6 wheels stopped the coach and NOTHING drug! Not none but the rear wheels, none of them locked up!! Very interesting…..
This means if you ever replace 1 set of shoes do all 4, they all work together. I’m not going to use Car Quest shoes … maybe having all 4 of the may be OK but they ran 100 degrees hotter adjusted identical. We use riveted organic basic shoes and watch the wear. Now John’s 23′ coach will stop an give you change with a complexly stock system. This is a test I would have never spent all that time to document but doing it gave us some very interesting and valuable results. So there ya go, benefit from our work.
To add one last line, recently there was a thread on Facebook I think about trying to covet all the part numbers… these 2 shoes carried the same part number but there were very different results from using them. We sell a set of now I can say “correct” rear brakes shoes… 2 wheels for $28, no cores. is it worth knowing you have the ones we have found to work? Yep, you can have all new shoes on your coach for $56… any takers?
Oh, and now that’s I’ve spent 10 hours figuring out something that does not seem to be found before, please don’t call me for the part numbers… buy them from me, they are cheap! And don’t just think any brand brake shoe or transmission filter kit, Temkin front wheel bearings, carb gaskets, intake gasket sets are all the same…. they are not!
Enough for today, took me bout all day to get it finished.
