4 brake fade

  1. 1. Brake Fade
  2. 2. Brake Fade • With prolonged application of brakes, their effectiveness decreases. This is called fading of brakes. • Higher vehicle speeds give rise to excessive temperatures during braking. • Drum temperatures may rise as high as 250'C during braking. • Such a high temperature results in fast wear of the linings and brake fade, i.e. heat temporarily changes the friction properties of the brake linings and brake pads. • A 'hard' brake lining fades sooner and this leads to 'wheel skid'. • The brake drum must be of such a material that it may quickly dissipate the heat developed during braking.
