how do i tell if i have left over gm brakes or not.. its a 6 of 99 build..
I checked my manual and it just talks about the wheels. I'm not sure there is a way. But i bled the system again and this time i found some air. Finally some progress! Now it only takes 2 pumps while driving to get brakes. lol Seems though the right rear line or the rears in general have air still. I can hear the rear brakes smack the drum when I hit the brakes sometimes.
Magic I think most 2nd gen all have GM brakes. If you want to upgrade I have heard talk about a 96 or so Chevy 1ton rear wheel cylinder can be put in for more stopping power.
Bigman07 Sorry Sir I have not yet looked into this for you been busy elsewhere. Good to read you are making a headway with it.
As for brake upgrade for the 1500's, you can use the 2500 brake calipers, bigger master cylinder. I am not one for saying install the bigger rear wheel cylinders as the rear brakes already like to lock up under wet/slippery conditions.
No worries Merc. I'll get it all figured out eventually. Only reason I know of the larger wheel cylinders is the diesel pulling guys do that change because of the larger tires they run and it fits all 3 sizes. I'm going to bleed the brakes again tonight and hope for more air out of the system.
I decided to check the TSB's for the 4wabs and found this for you.

Hope it helps
Well after beating my head into the wall I figured out what it was... I am an idiot...
When I first pulled the drum off to change the wheel cylinder the brake adjuster wasn't where it should be. It was just kinda laying in the pads area. I put it where it belongs without another thought... Well I should have thought that the adjuster is all the way closed... So therefore the new wheel cylinder was having to go beyond the normal travel to operate the brakes. I adjusted the brakes out where they belonged and everything is great. Thanks for all the help Merc and others! This one had me goin for a loop but it was just s simple overlooked adjustment.
You're Welcome anytime.
Right on man good to read its fixed and well shit happens.
Yeah it does haha
Do you happen to know if the adjuster keeper is listed anywhere as a part number? Mine is bent all out of whack.
My parts books go from 94-08 yes I have part numbers lol. But what part is the adjuster keeper?
In the 2000 parts book page 106 is where the brake parts start, do you have this book? Can I get a photo of said part?
See if any of these number match what you have. I highly doubt I can get them at the parts store. It's probably all dealer only stuff but here goes...
In the above image the part that is messed up on mine is the Adjuster lever. In the process of trying to find a picture I came across an ebay add for the exact parts I need so there is hope haha But for information purposes Here are the part numbers I found.
Lever Right: 04383276
Lever Left: 04383277
