Can brake pads become contaminated?
Brakes can be easily contaminated by oily substances such as brake fluid, chain lube and other kinds of oils and lubes. For this reason, it’s a good idea to keep any aerosol type lube well away from your bike, in particular your brakes. Once contaminated, it’s often difficult to resurrect your brake pads.
What would happen when braking with contaminated brake lining?
Abrasive friction materials will wear away at high spots, creating disc thickness variation and pulsation. Adhesive (adherent) friction material could deposit the friction material unevenly and cause brake judder.
How do you clean contaminated car brakes?
Clean the brake pads. Pry and scrape off the old shims, and then clean the pad by applying brake cleaning fluid and wiping with a rag. Stubborn dirt can be removed with a wire brush or emery cloth. Look closely at the lining surface and scrape off any visible contamination.
Can a brake rotor be contaminated with oil?
Unlike the brake pads, the metal rotor doesn’t absorb oil. Just the same, the heat and the dirt can form a blackish layer on the braking surface. This layer of burnt oil and dirt must be removed. In addition, oil tends to remain trapped in the rotor’s cooling vents, with the risk that it will contaminate the pads after cleaning.
What does it mean when your brake pads are contaminated?
And, for brake pads, it has dual meanings. First, it can mean a contaminated friction surface that alters friction levels and performance. Second, it can mean contamination to the environment from brake dust.
What happens to the rotor of a brake pad?
As this is happening, the heat is physically and chemically changing the exposed friction material, and bits and pieces are being torn or sheared from the rotor and pad. Some particles become embedded to the friction surface of the rotor, while others are cast off to stick to wheels and other vehicle components.
How are brake pads affected by friction materials?
Some friction materials have a different material on the bottom layer of the pad. Friction is the force resisting the relative motion of elements sliding against each other. In the case of cars and trucks, it is the brake pads pushing against a rotor that changes kinetic energy into heat.

Why do you need to break in your brake pads?
Once those brake pads and rotors are mounted, it is essential to properly break them in. Bedding in, commonly known as breaking in, new brake pads and rotors is necessary for new brakes to work properly. The process works to put a layer of material onto the friction surface of the rotor from the brake pad.
Do you need to break in your brake rotors?
Average rating from 96 customers who received a Brake safety Inspection. Having new brake pads and rotors installed happens on a regular basis. Once those brake pads and rotors are mounted, it is essential to properly break them in.
