Symptoms of a Faulty Volkswagen Jetta Brake Caliper Bolt
The brake caliper bolts of the Volkswagen Jetta play a significant role in the performance and reliability of the car's brakes system. It's important that you detect even the faintest and earliest signs of troublesome ones. Failure to work on these may result to you driving a vehicle with handling problems. If the bolts fail, you'll begin to experience various stopping issues because the brake pads that rely on these aren't held well against the brake rotors. Avoid this kind of problem by knowing what some of the symptoms of a Jetta with faulty brake caliper bolts are to keep everybody's driving experience safe.
There are unusual noises coming from the wheels.
High pitched whistling, endless rattling, annoying grinding, and any other odd sounds coming from the wheels aren't a good sign for your Jetta. When you can hear these types of noises, chances are you have brake caliper bolts improperly secured in the brakes assembly. There's a certain torque measurement you should aim for when you install these, and that number depends on the year and trim of your car.
Brakes are stuck even if the pedal isn't stepped on.
The Jetta's brakes should only be engaged when you step on the brake pedal. A car that seems to be coming to a stop even if the pedal is free means the brake pads continue to be in contact with the rotors. As far as the brake caliper bolts are concerned, these may have been installed unevenly: one bolt is set to the right torque while the other is on too tight or too loose. This "off" screw forces the one side of the pads to be pushed closer by default. Adjust the bad bolt to solve the problem.
Caliper is loose while it sits on the rotor.
An installed caliper that seems to be easily movable by hand points to a structural defect in the assembly. The reason why this happens is because the female/internal thread of the bolt has been loose and worn. When this happens, it's time for you to replace both the caliper and its bolts. The brakes should be tight and solid to be able to properly stop the car.
