K so the brakes on my 85 k10 are cauding me problems. The parts I replaxed already are the two rear wheel cylinders, brake booster, fluid, front calipers, and pads. The issue is that the rear drums are locking up and I have eneven braking in the front as I can feel the passenger side brake and pull to that side. Also after one day of driving the rear driver cylinder busted again, so ima replace it. The proportioning valve was reset and I feel as if thats my issue. What do ya think?

Is this issue new or has it been going on for a while?
What do you mean about the cylinder broke?

Well I've only been driving the truck for the past month since its a working progress. What I mean by cylinder broke again, I meant its leaking again.

Yeah, I have also had them fail right out of the box. The brake fluid will make that brake grabby. Hose them off with plenty of brake clean, make sure your primary and secondary shoes are in the correct positions and that the rears are adjusted equally. On the fronts be sure you have them bled out really well and that the slides move freely.

If you are talking about the front brakes here then you at the very least need to replace the driver front hose because it may have a blockage. I would do both sides.
