Abstract: 1,219,778. Automatic adjusters for disc brakes. SUMITOMO ELECTRIC INDUSTRIES Ltd. 25 Nov., 1968 [25 Nov., 1967], No. 55822/68. Heading F2E. Friction pads 3 mounted on backing plates 4 on each side of a disc 1 are urged off by a pair of resilient means each having a head 10 secured to a backing plate 4 and at least one leg 9 slidably engaging a guide pin 8 extending through apertures in the backing plates 4 and having at least one end removably secured to calipers 2, said engagement having a frictional resistance which can be overcome by a force applied by the brake applying means 6 to slide the backing plate 4 along the pin 8 and thus take up brake wear. The head 10 is secured to the plate 4 at a point offset from the centre of the pad 3 towards the leading edge. Clearance is thus greater at the leading edge than at the trailing edge so preventing squeal when the brakes are applied and squeak when the brakes are off. Each backing plate 4 is engaged by two pistons 6 sliding in cylinders 5 in the calipers 2.
