I have a 94 s-10 pickup 4.3 ''z'' code ABS. Repaired broken section of brake line, no leaks, bled lines. Get good pedal until I start engine. Then pedal goes to floor. Bled rr lr rf lf. What''s wrong ?
Hi 49er, Super tech here. I just wanted to ask you if you had bled the master cylinder?
yes I did. rebled entire system. now have some pedal pressure - not normal. also adjusted rear brakes.could not bleed isolation dump valve.
Relist: No answer yet.
Hey 49er, me again. I have gotten some info on a recall for that vehicle. You might want to check with the dealer and see if it hasn't been done of has.
Hi Super tech, We just kept bleeding the system over and over and its finally OK. Any idea why it was such a hassle? Thanks - 49er
There might have been some air trapped in the ABS valves, that will do it to ya sometimes. I have had some that when I came in the next morning, Poof.. the pedal was good. Like it just had to sit for a while..??
Anyway, I'm glad you got brakes now.... I hate driving without them!..... lol
