1983 Chev G-Series Van Malfunction - Chassis, Suspension & Steering

Question: I have a right caliber that appeared to froze up. I have replaced it and bled lines. Took out for a test drive and the same condition still exists. Is this a failure mode of the proportioning valve? Number two is this resetable. And if not where can a get a rebuilt and new one.

Technican: Hello, If you haven't replaced the brake caliper flex hose I recommend it. The caliper receives your hydraulic pressure from the foot brake master cylinder okay. But, when a flex hose material breaks down (within) from age, it can cause a restriction that prevents correct flow volumn of fluid to allow the caliper to release when the brakes are no longer applied. The caliper remains applied (stuck) because pressure that applied it, can't be relieved. Most often the flex hose which looks fine and is not kinked is still internally faulty. A proportioning valve has to do with front vs. rear brake fluid flow. In the event one axle's brakes hydraulically fail, the valve will shift and direct fluid flow to the opposite axle to slow/stop the vehicle with the remaining good axle's brakes. The brake warning light on the dash would stay lit up because the fluid level would be low in the master cylinder due to a leak. Once repairs are completed the valve resets itself with the restored pressure coming from a properly working master cylinder. Make sense?,
Owner: ...you were right on the flex hose looked fine and there was no external sign of a problem. I was giving this vehicle away to a guy down on his luck and you made the hit on the repairs not so bad. THANKS AGAIN ARNEJ
