Ok, so i've been having hella problems with my Yukon and the brakes. everytime i get it fixed it seems to be another problem that arises. This is wha ti've replaced so far:
both front calipers
both front rotors
both front pads
both front brake lines
wheel cylinder
master cyclinder (twice)
abs pump
INitially, the brakes were locking up and i didn't know that the previous owner pulled the ABS light from the dash. The abs pump/ecu was throwing 13 codes, Thus, i had to replace it. Everything was better until it locked again....disocvered it was a rusted backing plate, creating play when the brakes were applyed causing the wheel cylinder to pop out and not return to its resting position. THe place i took it to bled the abs pump too.
Now, i just replaced the master cylinder again because the pedal is too mushy and when i press the brakes the brake light came on. Bench bled the master cylinder, Bled the system, was a hair better, but now the spongy brakes are back again and the light is back on.
No drips, no leaks (that i can see)...no idea.
One thing i did notice, however, is that I put brand new fluid in he entire system...bled out all the old fluid. But now the fluid is extremely dirty...
Could this be a bad brake booster?? Thats the ONLY thing that hasn't been replaced
My thoughts is tha ti wanna get rid of this entire abs system...can it be done??
