Hey folks, I'm at a loss here with my brakes... Buckle up for my life story...
I've been dealing wish squishy brakes for about 2 years on my 98' C1500 Sierra, Just recently bought a livestock trailer, so I figured I should get on figuring out why my brakes were squishy since I'll have thousands of pounds of livestock behind my truck soon. About 3 years ago I had the ABS module, calipers, rotors, shoes and pads replaced on the truck. Just recently checked all of that and the pads/shoes look like new still. So everyone I've talked to so far has said it was the master cylinder leaking internally, so I just replaced it, the new doorman one was junk as well and began leaking for the gaskets out of the package, so I did the NBS upgrade like everyone said, bench bled it, bled the lines at the wheels, solid brake fluid, no air. STILL have squishy brakes! I then bought an Autel and did an ABS brake bleed, as well as bleeding everything at the wheel cylinders, STILL NOTHING. The brakes grab great once you've pushed hard enough on the pedal, but its the amount of travel in the pedal that concerns me. It sounds like I'm pushing down on a bag of air until the brakes start to grab. For a reference point, I get zero breaking power until my brake pedal is about even with my gas pedal (a fair amount of travel in my opinion).
So any suggestions on how to get rid of this spongy, squishy, cloud like brake pedal?
I've considered the brake booster to be suspect, but it doesn't seem to show the signs that a bad booster would show.
Thanks everyone!
