Abstract
A floating-caliper spot-type disc brake whose caliper member is retained and guided on parallel pins clamped in the brake carrier member. A sealing boot is provided which protects the pins against moisture and dirt. One end of the sealing boot is armored by a crown spring having finger-shaped spring arms which firmly urge the one end against a part of the pin. A bellows portion succeeding the one end extends at right angles to the longitudinal axis of the pin and permits swivelling of the brake caliper relative to the brake carrier around one of both pins for a change of the pad without excess twisting of the sealing boot. The other end of the sealing boot is armored by a metal ring and engages with a groove which is provided at the open rim of the opening for the pin.
