No rear brakes

[lgharold]

90 Q-45 no rear brakes. Jacked up rear, applied breaks and wheels turn when put in drive. Front brakes work, abs works on frt, I bled brakes, I have a fractory manual, it says replace master cyclinder. Any other suggestions.

I've never heard of this before... almost seems impossible that you're getting fluid to the rear brakes (had to to bleed them) yet they're not working...

I would make sure you're getting fluid to the ABS actuator by trying to bleed the rear bleeder valve. The master cylinder feeds the ABS actuator.

Id agree with the master cylinder thing... Could be the proportioning valve is screwed up.
