How's everyone doing? I'll try and make this short. Both ABS and break lights are on breaks would bleed down while at a stop light or sign. Bleed breaks starting with R R, L R, R F, L F. Worked for a few hrs, back to bleeding down. Bleed them again same, replaced master cylinder. Bench bleed MC no air bubbles,swapped old with the new. pumped all old fluid out of lines. Bleed all the breaks. ( engine off ). Now its worse then it was before, soft pressure all the way. Breaks are there, stomp on it and they lock up. Noticed today that the fluid is no longer clean, almost brown. and it seams like its pushing the fluid out threw the MC because top of reseivor is wet with break fluid. the fluid level hasn't drop. Any in-site would be much appreciated.

 

If you replaced the master cylinder you have air in the abs system that needs to be bled out. You need a DRB III tool (dealer or big garage) to cycle the solenoids to bleed it.

 

Thank you. Much appreciated.
