Fellow Stangers! Hope all has been well. I have been gone for a few months but I am back. Almost sold the stang.

Got a brake issue. Front right caliper locked up. Replaced that. rear left caliper locked up. replaced that.

Power flushed the system.

Rear breaks are really weak. almost wont stop the wheels. If it dose i can still turn them by hand while the pedal is held.

Is this my Master CY? or is it the Proportioning valve?

What do you all think? Thanks!!! :mad:

Well I'll let yall know I guess -- I am going to try and just chage the Prop valve / proportioning valve and see.

When changing that do you need to bleed the brakes ? I am sure I do but just curious.

My guess would be proportioning valve.

Bad MC would cause them all to be weak, or fail, not selectively.

And whenever you open brake fluid to the environment, I would suggest bleeding the brakes. I also highly reccommend a speedbleeder, or vacuum bleeder. I did it the hard way last time, and it is just too much of a hassle.
