QuestionI own a 1989 Mercedes 190E 2.6L I tried to flush my brakelines by pumping the brakes. I didn't get any fluid from the rear calipers and the left front caliper. I replaced the master brake cylinder with a new unit and the same results. My ABS slso remains on the dash. The brake light had never lit on the dash. Now I'm thinking is it the ECU? What's your thoughts.
AnswerThe ABS issue can NOT be addressed until your other issues are repaired, and may vanish with them...
If you are still not getting fluid at front/rear wheels.
Replace all four flex hoses, then use a step bleed.
Keep the master cylinder totally full = as close to running out the top of reservoir as is possible.
Step bleed = close all bleeders, open right front, and rear, step on pedal (single stroke, NO pumping), and hold it on the floor until both bleeders are closed, repeat as needed until fluid comes out of both front, and rear right, then go to left side, following the same procedure.
Repeat the entire procedure until you get nothing but pure fluid from every bleeder on each stroke.
