A brake service should also check the brake fluid: if it contains too much water, the function of the Antilock Braking System (ABS) and Electronic Stability Programme (ESP) will be impaired.
It is recommended to have your brake fluid changed every 2 years regardless of the vehicle age.
Did you hear?
Some brake noises are normal. Others can indicate problems…
Grinding due to rust build-up on the rotors is of little concerns. The build-up usually can be knocked off, sometimes it disappears after a few stops. However, if grinding persists, there could be a more serious problem with the rotors or pads, and you should head straight to the service department.
Disc brakes with wear indicators may produce noise that indicates it’s time to change the pads.
Trace squeak or squeal
Semi-metallic brake linings sometimes emit such a sound. Rain, humidity or cold brakes in the morning also could be the source. If the problem persists, have it checked out.
Sometimes accompanied by a slight pulsing in the brake pedal at low speeds, this is most likely the anti-lock braking system performing a harmless self-check.
