You need to see a professional for this problem when the car’s parking brake starts engaging and disengaging on its own.

 6. Worn Brake Rotor:-

This problem of a worn brake rotor can also cause the rotor to grind against the inside of the disc. This problem can be easily noticeable as and when your car starts vibrating while putting on the brake or while stopping the car.
