Master Cylinder ?

Has anyone ever had the problem of the fluid pushing from the rear resivor to the front on the master cylinder? Is this the proportioning valve going bad? I've never had this happen.

Re: Master Cylinder ?

I just had this problem with my truck, definetly frustrating. Took my truck to the shop, because no shop could help me on the phone. They put a new proportioning valve on and same issue, new master cylinder and problem solved. Hope this saves you the calls and headache.
