1500 rear master cylinder

Postby mookie54 » Mon Nov 09, 2009 4:20 pm



I am working on my neighbors 1990 1500 and the problem is no brake pedal (on rear brakes).
I have rebuilt master cylinder and still no resistance. I cant find any info on the pressure control valve incorporated in the rear master cylinder if this unit is bad could that give the symptons I have? I can find no evidence of leaks anywhere on the system. Any help would be appreciated.

Keep in mind the 1500 has linked brakes - so the rear pedal operates the rear brake as well as one of the front brakes. You need to bleed both of them if you have got no pedal pressure. The bleeding procedure is a little complicated - have a look at the service manual for it.

The rear is linked with the left front. You will need to bleed the LF caliper first. Once the air is out, you can bleed the rear. The best way I have found is to use a vacuum bleeder.

I am having the same problem on a 1988 1500. No evidence of any leaks and lost all resistance.
I rebuilt the master cylinder couldn't get any resistance, then re-honed and re-built the master cylinder again. I used a vacuum bleeder and bled the front left and then the rear, and still have no resistance in master cylinder. Is there a control in the rear hydraulic system other than the master cylinder and the two calipers?
