Ok guys my 1994 K1500 has the great jb5 brakes, that's the 10" rear drums. My issue with them is getting them adjusted properly. I have tried many times and have many new parts but still I can't get them to work and allow me to use my parking brake that will hold them truck on a hill? Gone through the steps in the GM manual and have a brake measuring tool it suggests.
My prob is that when I get them adjusted and where the parking brake will hold the truck on a hill I check the drums with the rear in the air and spin, but its mostly smooth but then at times I can here it rubbing, say out of a 360 degree rotation I get 45-90 degrees worth of rubbing each side? I have replaced the rear wheel bearings and notice I still have a little play which I think is due to some wear on the axle shafts where they meet the bearings. Could that be causing my issue?
recently replace items,
Shoes
all 3 parking brake cables
2 new drums
1 new wheel cylinder
drum brake spring kit
Adjusters seem fine and lubed the threads
Truck specifics;
1994 K1500 Extended cab JB5 brake system, 350, manual trans, 10 bolt rear end, z71 but non-heavy duty(that why the small brakes and small rear end)
