What is brake fade?

A. Pad bite is called the coefficient of friction. At high temperatures, all brake pads have a reduced coefficient of friction. This is called brake fade. Power Stop engineers all of our friction compounds to resist brake fade. This assures safe, consistent stopping power. Our technical data page shows benchmarking information. Different grades of pads will have different fade characteristics. The Z36 pads are by far the most fade resistant pad that is commercially available.  more

There are many diferrent types of brake fade, the most common is "Pad Fade". Pad fade is the loss in effectiveness of your brakes after braking hard several times in a row within a short period of time i.e. (road racing).  more

Vehicle braking system fade, or brake fade is the reduction in stopping power that can occur after repeated application of the brakes, especially in high load or high speed conditions. Brake fade can be a factor in any vehicle that utilizes a friction braking system including automobiles, trucks, motorcycles, airplanes, even bicycles. Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disk brakes. Loss of stopping power, or fade, can be caused by friction fade, mechanical fade, or fluid fade. Brake fade can be significantly reduced by appropriate equipment and materials design and selection. Brake fade occurs most often during high performance driving or when going down a long, steep hill. Owing to their configuration this is more prevalent in drum brakes. Disk brakes are much more resistant to brake fade and have come to be a standard feature in ...  more

Fade, or brake fade is the reduction in stopping power caused by a buildup of heat in the braking surfaces (and in the case of drum brakes the arc of the brake shoe don’t match the arc of the drum in response to heat). Brake fade can also be caused by the brake fluid boiling. Compounds are held together by resins, these resins can revert to gas when high temperatures are reached. When this happens the brake pads can “aquaplane” on a film of gas created by the over heated resins. Many low quality pads suffer continuous fade at very low temperatures.  more

All pads contain some organic (living) materials. Resins that bind pads compounds together are organic-petro-chemical products. When Brake Pads reach high temperatures, the resins revert to gas and cause the pads to "aquaplane" on a film of gas (this is called "fade"). Some pads only fade once or twice and then settle down (green fade or bedding-in fade). Many cheap low quality pads will suffer from continual dynamic fade, sometimes at surprisingly low temperatures.  more

Definition: A reduction in brake power due to lessening of friction between the brake shoes and drum or pads and disc. Brake fade often occurs from heat buildup due to repeated or prolonged brake application.  more

thats when you pump up the brake and with a steady pressure on the brake pedal, it slowly will go towards the floor, then you have to pump it up again. its probably the master cylinder by-passing, and needs to be replaced, or air in the lines.  more

Under heavy braking, you get alot of heat build up. That heat causes a couple of problems. Hot gasses can build up and expand between the pads and the brake surface. This reduces the contact area between the two surfaces and reduces stopping power. It can also cause the brake fluid to boil in extreme situations and add gas to the brake lines. Gases in your lines will make the brakes very ineffective.  more
