The present invention relates to a brake holder of a floating-caliper disc brake for motor vehicles at which brake pads arranged on either side of an associated brake disc are displaceably mounted. To ensure ease of displaceability a brake pad guide spring is provided that extends between the brake holder and the brake pads. For ease of mountability of both the brake pads and the brake pad guide spring, it is arranged for that the brake pad guide spring is mountable on the brake holder in a generally radial direction and is locked at the brake holder in both radial and axial directions by means of at least one fixing clamp, and at least one spring arm is designed at the brake pad guide spring and fixes at least one brake pad under spring bias in position on the brake holder in a clearance-free manner. These provisions not only improve the mountability of a brake of this type but also the rattle-free resilient arrangement of the brake pads.

The invention claimed is: 1. A brake pad assembly comprising a brake pad and a guide spring for engagement with the brake pad, the brake pad including a main portion and a lateral guiding portion extending from the main portion, the lateral guiding portion including a stop surface located on a first side of the lateral guiding portion and a radial extension located on a second side of the lateral guiding portion, the second side being radially opposite the first side, the guide spring comprising an end portion for engagement with the stop surface, the end portion comprising an axial spring force component with a sloped edge that is sloped in the axial and the radial direction such that the slope edge has a first end and a second end radially offset from the first end, the guide spring further comprising a guiding channel having a depth for receiving the radial extension. 2. The brake pad assembly of claim 1, wherein the guide spring comprises a cantilevered spring arm that terminates tangentially inwardly over the guiding channel. 3. The brake pad assembly of claim 2, wherein the spring arm comprises a pair of V-shaped hinge portions separated by an opening and a central ramp portion extending between the V-shaped hinge portions, the central ramp portion forming a sliding surface that bends radially toward the guiding channel to allow the lateral guiding portion to slide radially over the ramped surface and into the guiding channel. 4. The brake pad assembly of claim 1, wherein the end portion of the guide spring comprises a contoured edge for engagement with the stop surface. 5. The brake pad assembly of claim 4, wherein the contoured edge comprises a convex edge. 6. The brake pad assembly of claim 4, wherein the contoured edge comprises an angled-off edge. 7. The brake pad assembly of claim 1, wherein the guide spring comprises an elongated base having a first end and a second end, and wherein the guiding channel comprises a first guiding channel section extending from the first end of the base for receiving the brake pad, and a second guiding channel section on the second end of the base, the second guide channel section being separated from the first guiding channel section by an opening. 8. The brake pad assembly of claim 7, wherein the spring arm extends over the first guiding channel section but not the second guide channel section. 9. The brake pad assembly of claim 1 further comprising a contact surface adjacent the guiding channel, wherein a section of the contact surface is partially cut to form a flexible fixing clamp. 10. A brake pad assembly comprising a brake pad and a guide spring for engagement with the brake pad, the brake pad including a main portion and a lateral guiding portion extending from the main portion, the lateral guiding portion including a stop surface and a radial extension having three sides, the stop surface located on a first side of the lateral guiding portion and the radial extension located on a second side of the lateral guiding portion, the second side being radially opposite the first side, the guide spring comprising an end portion having an axial spring force component with a sloped edge that is sloped in the axial and the radial direction such that the sloped edge has a first end and a second end radially offset from the first end, and the guide spring comprising a guiding channel having a depth for receiving the radial extension and surrounding the three sides of the radial extension. 11. The brake pad assembly of claim 10, wherein the guide spring comprises a cantilevered spring arm that terminates tangentially inwardly over the guiding channel. 12. The brake pad assembly of claim 11, wherein the spring arm comprises a pair of V-shaped hinge portions separated by an opening and a ramp potion extending between the V-shaped hinge portions. 13. The brake pad assembly of claim 10, wherein the lateral guiding portion comprises the stop surface, and the guide spring comprises a contoured edge for engagement with the stop surface.
