Improvements in self-energising disc brakes.

摘要

In a self-energising disc brake of the spreading type complementary pairs of angularly spread discrete pads (7, 8) are provided on adjacent faces of the pressure plates (3 and 4) to define ramp surfaces (12,13) inclined with respect to the planes of the plates (3, 4). The ramp surfaces of each pair co-operate slidably to urge the plates relatively away from each other in an axial direction when the plates are moved relatively angularly by a brake-applying mechanism.
