Good afternoon Gurus!
I need help. '00 LX470 265K on her.
So about a week or so ago, I lost almost all braking power. After a bunch of reading here, I ordered up a master cylinder kit and made plans to rebuild it. While I had the MC out of the car, I took the ABS pump motor off and had a look at it. It was a mess. Some of the metal was worn down to the plastic on the motor armature. I will post a picture shortly. Anyway I cleaned the motor up put it all back together and drop 12volts on it and spun nice and strong.
MC kit comes and I replace the plunger and put all of that back together and throw it in the car and start bleeding. Fronts bleed fine, When I go to do the rears, I get almost nothing. I go and check the motor accumulator, and I am pretty sure it is not running. After some more reading around here about bleeding the accumulator I loosen all four brake lines at the MC and the fronts pump great and I tighten them up, but I can not get anything from the rear lines at all.
Is there a way to test the motor / accumulator in the car? Is there something in the ABS computer on the MC that would shut it down? I read something about that somewhere but I can not find that thread now.
Why would the master have front pressure but no rear pressure?
Oh and I should add, the VSC computer is dead, so I cant read codes from it. Its been that way for about a year. I finally ordered some of the 4k resonators to do that repair as well.
Thanks in advance!
