Abstract: A disc brake (10) of the floating caliper type wherein the caliper (14) is slidably mounted on the torque plate (34) by two guide pins (60) which are received in complementary grooves (62, 66) in the torque plate and caliper and which are held to the torque plate by screw bolts (74) passing through bores (72) in the adjacent portions of the torque plate. The pins and grooves have sufficient wrapping engagement to allow limited sliding movement of the caliper on the pins while precluding separation of the caliper from the pins. When one guide pin is released by unscrewing the related bolts, the caliper may be pivoted about the other pin and then removed from the torque plate.
