Abstract: A sliding caliper disc brake has a fixed carrier carrying directly and indirectly actuated pads. A caliper is slidably mounted on the carrier and carries brake actuators. The backing plates of the pads are provided with ribs for engagement in corresponding grooves in the carrier and arranged to provide additional support for the caliper, in use, in the vertical direction.

Abstract: A sealing device for use with a bleed screw of an hydraulic system comprises a one-piece moulding of rubber or plastics material. The sealing device comprises a sealing ring of frusto-conical outline, an end cap, and a flexible strip interconnecting the ring and the cap. In its position of use the sealing ring is clamped between a shoulder on the bleed screw and a plain face on a caliper which surrounds a threaded bore into which the bleed screw is screwed. This prevents foreign matter from entering the screw threads externally. The end cap is detachably deformed over a bead at the free end of the bleed screw to prevent moisture or foreign matter from entering the bore through a bleed passage in the bleed screw.
