Hard brake pedal and hard left pull when braking
2001 F350 PSD 4x4, 99K miles.
The other day my son comes home all worked up over having almost T-boned someone that ran a red light. Full on panic stop, missed the car by about 6" he said. He said that afterwards, every time he hit the brakes, it would pull hard left. Went for a test drive and sure enough, it will throw you into the other lane if you aren't ready for it.
I pick up a set of new pads for it, and start with the driver side front. No issues there, replace the pads. Go to the passenger side, and I can't compress the pistons AT ALL. (yes, the cap was off of the MC) OK, problem found, need a new caliper. Figure I'm doing one, might as well do both. Replace both calipers the next evening, start bleeding (2 person method). Note that the passenger side is difficult to bleed, not much pressure there. Finally get them bled, and go for a drive. Same problem, hard yank to the left upon braking, like that side is the only one working.
The back brakes have been non-existent for a while. No pressure is getting through the ABS module. Could the problem in that module have moved to the front passnger side, or is it a MC issue? I'm going to replace the MC this evening in hopes that will solve it.
The pedal in this truck has always been very hard. Is that indicative of a hydroboost issue? May as well replace it at the same time?
