2005 Buick Rendezvous Repair Question
2005 Buick Rendezvous rear brakes drag/heat up
2005 Buick Rendezvous 6 cyl Front Wheel Drive Automatic
I have replaced calipers, rotors, pads & flex lines and still have drag and heat up situation. I have been told it could be the proportioning valve?
The proportioning valve is designed to limit the amount of fluid pressure to the rear brakes. When working properly, the front brakes should do 60% of the stopping and the rear 40%. Is is possible that internally, something has gone bad in the valve and it is no longer allowing fluid to properly return.
