I have a 99 Lincoln Navigator 4WD with 4 wheel ABS. I replaced front rotors, calipers, and pads. Bled the brake
system, but can't get pressure. The pedal will go to the floor with pretty light effort. Replaced the master cylinder, bench bled before installation. Re-bled the rest of the lines, still can get a firm pedal. Can't find any leaks. Suspecting a problem with the ABS unit.
JA: How old are the brakes? How many miles on the car?
Customer: 185K miles on the car. Fronts are totally new. Rear are a few years old.
JA: Are you fixing your Navigator yourself? What have you tried so far?
Customer: Yes, I am a former mechanic. Multiple attempts at bleeding the lines and the parts listed in the first response I send including the master cylinder.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No, i think that is all that I can think of. Thanks.
