Good Evening Folks;
My son's 240 wagon brake system is giving us fits. We had a leaking master cylinder that we changed and the car developed a soft pedal afterwards. Using the advice in the archives I removed the master, bench bled it and then pressure bled the system. Still a soft pedal. We then started having rear brake pulling to one side, the RH brake was warm to the touch after a run but the LH was cold. Seized caliper I thought. 2 rebuilt calipers went on, still the same problem. We rebuilt the junction valve, still no change. Soft pedal and pulling to one side with a cold LH brake. So, could it be the proportioning valves? The car has close to 300,000 miles on it, perhaps with all the breeding we did chasing the soft pedal we have disturbed something?
Would anybody have a pair of used valves they would like to sell. At $100 ea this is getting pricey.
Regards;
