1. A disc brake comprising - a rotary disc (D) fastened to a rotary portion to be braked ; - a non-rotary bracket (S) comprising two arms (2, 3) located on one side of disc and supporting two guiding elements (4, 5), such as pins, located near the disc periphery, spaced along the circumference and extending parallel to the disc axis ; - two friction elements (6, 7; g) located on both sides of the disc and slidably mounted on the guiding elements (4, 5) ; - a yoke (E) having two branches (8, 9) which overlap the disc, one of the branches (8) on the one side supporting a device (10) for actuation of the brake, said device being adapted to press a first friction element (6, g) against the disc, and, on the other side, being slidably mounted on the guiding elements (4, 5), while the other yoke branch (9), due to abutting reaction, shifts towards disc the second friction element (7, g), to which said branch is fastened against movement in the radial direction and in the circumferential direction by a fastening member (12), the whole being such that the braking reaction forces are supported by said guiding elements, such as pins (4, 5), characterized in that one (4) of said guiding elements is removably mounted on the bracket (S), said bracket is provided with means (C) for centring said guiding element and means are provided for relieving that guiding element from braking reaction forces.
