Abstract

The disc brake has the shafts from a pair of road wheels mounted in bearings (15) at each end of a common housing. The shafts are aligned with each other, but not mechanically connected, by a double ended spigot (3). Each shaft has keyways (5) for brake discs (1a, 1b) whilst the brake pads (6a, 6b, 7) are guided by bolts (16) which connect the end housings together. Annular pistons (10) are fitted in annular cylinders (11) and are independently actuated by hydraulic pressure so that brake can be operated even if one cylinder should fail.
