Abstract

A disc brake, particularly suitable for use in tractors and like vehicles, is disclosed. Balls are located in complementary inclined recesses in a pressure plate and in an adjacent end wall of the brake housing. The brake is actuated by radial movement of the pressure plate, which produces a camming effect as the balls tend to ride out of the recesses, so that the pressure plate moves axially to urge a rotatable friction disc into engagement with a surface of the housing. Pilot pins engage with lugs on the pressure plate, constraining it against angular movement, so that when on application of the brake the pressure plate engages the friction disc, the pressure plate is prevented from being carried round with the friction disc, ensuring that no servo effect takes place.
