- Our Disc Brake Cleaner can improve braking performance by rapidly removing brake dust and oil, as well as dirt and grime from all braking parts. Its unique formula has added conditioners that rehydrate your disc brake pads to dramatically reduce brake squeal, prolong the disc pad life and restore braking performance. Muc-Off Disc Brake Cleaner air-dries rapidly without leaving any residue, and it’s perfectly safe on rubber, plastic, anodized metals, carbon fibre and painted surfaces.
