Diagnosing 2003 VW Jetta Brake issues

RE: Diagnosing 2003 VW Jetta Brake issues
Crimping the flex hose generally damages it, especially an older hose. They get hard and brittle with age. Brake hose is made in layers like a tire so crimping is the same as hitting a curb with the side wall. It damages the plies and they can separate.

Try this and see if it makes a difference....

Apply the pedal hard and release. Note how much effort it takes to spin a wheel. At that point crack open the fitting between the hose and the steel brake line. If the wheel is still hard to turn then open the bleeder. If that makes it easier then you know the restriction is the flex line for that wheel.

BTW, always replace brake parts in matching pairs... front or rear.
