But, the coefficient of friction goes up as the brakes get hot. The concept of brake fade can happen to anyone, and is most commonly a result of issues on the interior of the braking system. She also notes that warmer temperatures can draw out dyes from the fabric, and also set pre-existing stains into the garment.

Step 5: Apply the emergency brake cautiously. For this reason, new brakes should always be treated as carefully as possible for at least the initial 100 miles after they have been installed. The phenomenon known as brake fluid boiling, which is invariably associated with the release of compressible gas, is created when there is insufficient brake fluid in the system.

Beyond that fade and wear become serious issues. The addition of chopped steel and other metal fibers to the material allows the lining to withstand higher temperature and to also conduct heat away from the rotors, unlike NAO compounds which conduct heat poorly and act like insulators to keep the heat in the rotors. For DOT 3 fluid, the minimum dry (contains no water) boiling temperature is 401 F and the minimum wet (saturated with water) boiling temperature is 284 F. For DOT 4 fluid, the minimum dry boiling temperature is 446 F and the wet boiling temperature is 311 F. Most fluids exceed these minimum specifications and provide an increased margin of safety. 12 Brake Repair Parts Needed for Brake Installation. for subscribers!
