Dear enthusiasts,
I'm experiencing stiffening of my brakes after a few pumps. The pedal initally regresses normally but eventually stiffens at the top and the car almost doesn't stop. However, it does not stay stiff for long. It loosens up as I drive on but the problem repeats at every braking interval...
I've a 99 boxster with 68K miles.
Please advise and thanks in advance.
