Worked about 3 days then pedal fell on the floor. No loss of liquid from the reservoir. About a car accident on the Autobahn with a child in the back seat. There was no warning. The car was thoroughly tested after installation with no signs of problems. Good solid brake pedal. Completed simulated crashes with Grace. I drove the car over 100 miles before losing the pedal again. This is the last Dorman product I will ever purchase. I have purchased their products before with mixed results but this is by far the worst.
