BRAKE SHOES

BRAKE SHOES

          Brake shoes are typically made of two pieces of sheet welded together. The friction material is together riveted to the lining table or attached with adhesive. The crescent shaped piece is a called the web and contains holes and slots in different shapes for return spring, hold down hardware, parking brakes linkage and self adjusting components. All the applications force of the wheel cylinder is applied thought the web to the lining and brake lining. The edge of lining table generally has three” V” shaped notches or tabs on each side called nibs. The primary shoe is located towards the front of the vehicle and has the lining positioned differently from the secondary shoe. Quite often, the two shoes are interchangeable, so close inspection for the variation is Important.

               When driver steps on the brake, the brake shoe is mechanical part the driver is ultimately controlling to bring the car to a stop. The backing of a brake shoe is a metal part, but that area that actually comes in contact with the brake is padded to provide friction to stop the car without damaging the brake itself.

              When a driver steps on the brakes, brakes fluid under pressure travels to the individual wheel brakes, and small hydraulic piston push the brakes shoes onto the inside of the spinning surface of the wheel. The friction from the brake shoes slows the wheel down and ultimately bring it to a halt. When the brake is released, spring pull the brake shoe back into a resting position clear of the wheel.
