I recently blew a rusted rear brake line during a sudden stop. Until that point my brakes worked fine and had normal pedal travel. This car has rear disc brakes which are not that common. I took the car to a local shop and had the steel lines replaces from front to rear. Following the line change the mechanic was unable to bleed any fluid from the rear calipers. They said there was a proportioning valve in the rear and did not seem to understand why. They concluded that both of the rear brake hoese were collapsed and would not allow fluid flow. They changed both and were able to bleed the brakes. Since then the car has excessive pedal travel. The pedal must be depressed 3/4 of the way to stop in normal conditions. If you pump the brakes, travel becomes near normal. They commented that the travel change must be because the rear brakes were not working before. The car has never had pedal travel like this in the 7 years I have owned it. What should I check next?
