This Liqui Moly Brake Anti-Squeal Spray is a synthetic special material designed for the braking system. It is extremely adhesive and resistant to spills and splash water, preventing and eliminating brake squeal noises that occur between brake saddle plungers or brake pads and brake pads. It secures the function of the entire brake system. The spray can be applied to the entire braking system on disc brake pads, stud pins, as well as attachment points for drum brakes. Contains 400 ml.
