Abstract

A disc brake assembly includes a brake clip having a U-shaped section, at least one retention tang, and an abutment leg. The U-shaped section has a base leg and opposing upper and lower legs extending from the base leg. The upper leg has an inner face facing the lower leg. The at least one tang extends away from the U-shaped section and inner face. The abutment leg extends from the lower leg and has a midpoint between a top edge and a bottom edge. The midpoint is not planar with the top and bottom edges.

First claim

What is claimed is:

1. A disc brake assembly comprising:
a brake clip having:
a U-shaped section having a base leg and opposing upper and lower legs extending from the base leg, wherein the upper leg has an inner face facing the lower leg;
at least one retention tang extending away from the U-shaped section and inner face;
an abutment leg extending downwardly in a generally perpendicular manner from the lower leg, wherein the abutment leg is bowed such that the abutment leg has a midpoint between a top edge and a bottom edge which is not planar with the top and bottom edges;

a support leg extending only perpendicularly from the upper leg and having a terminal edge defining an upper extent of the brake clip;
an anchor bracket having a channel in which the brake clip is mounted; and
a face portion on the anchor bracket, wherein the face portion extends only perpendicularly on the anchor bracket and is only partially covered by the support leg.

2. The disc brake assembly of claim 1 wherein the retention tang extends from the base leg.

3. The disc brake assembly of claim 1 further comprising:
an anchor bracket having a channel in which the brake clip is mounted; and
a groove in an upper surface of the channel, wherein the at least one retention tang is engaged in the groove.

4. The disc brake assembly of claim 3 further comprising:
at least one brake pad supported on the anchor bracket; and
a brake caliper slidably supported on the anchor bracket.

5. The disc brake assembly of claim 1 further comprising:
an extension leg extending generally perpendicular from the abutment leg, wherein a length of the extension leg is minimized and an inside radius between the lower leg and abutment leg is maximized.

6. The disc brake assembly of claim 1 further comprising:
a first guide extending from the base leg between the upper and lower legs; and
a second guide extending from the base leg opposite the first guide.

7. The disc brake assembly of claim 1 further comprising:
a retraction spring extending from the U-shaped section, wherein the retraction spring has:
an application portion; and
a transition portion, wherein the transition portion redirects the application portion from parallel to the brake clip to transverse to the brake clip.

8. The disc brake assembly of claim 1 further comprising:
a groove in an upper surface of the channel, wherein the at least one retention tang is engaged in the groove.

9. A disc brake assembly comprising:
a brake clip having:
a U-shaped section having a base leg and opposing upper and lower legs extending from the base leg; and
at least one retention tang extending upwardly from the base leg and into an opening provided in the upper leg; and

an anchor bracket having a channel in which the brake clip is configured to be mounted, the channel having a groove provided in an upper surface thereof;
wherein the retention tang has at least a portion thereof which extends through the opening and above an outer surface of the upper leg and which is configured to be received in the groove to assist in securing the brake clip to the anchor bracket;
a support leg extending only perpendicularly from the upper leg and having a terminal edge defining an upper extent of the brake clip;
an anchor bracket having a channel in which the brake clip is mounted; and
a face portion on the anchor bracket, wherein the face portion extends only perpendicularly on the anchor bracket and is only partially covered by the support leg.

10. The disc brake assembly of claim 9 further comprising:
at least one brake pad supported on the anchor bracket; and
a brake caliper slidably supported on the anchor bracket.

11. The disc brake assembly of claim 9 further comprising:
an abutment leg extending downwardly in a generally perpendicular manner from the lower leg, wherein the abutment leg is bowed such that the abutment leg has a midpoint between a top edge and a bottom edge which is not planar with the top and bottom edges.

12. The disc brake assembly of claim 9 further comprising:
a retraction spring having a first retraction spring portion extending from the base leg, a second retraction spring portion extending from the first retraction spring portion, and a first position without loading, wherein;
the first and second retraction spring portions move from the first position to a second position when loaded to a threshold load; and
the first retraction spring portion remains at the second position and the second retraction spring portion moves beyond the second position when loaded beyond the threshold load.

13. The disc brake assembly of claim 9 further comprising:
an abutment leg extending from the lower leg; and
an extension leg extending generally perpendicular from the abutment leg, wherein a length of the extension portion is minimized and an inside radius between the lower leg and extension portion is maximized.

14. The disc brake assembly of claim 9 further comprising:
a first guide extending from the base leg between the upper and lower legs; and
a second guide extending from the base leg opposite the first guide.

15. The disc brake assembly of claim 9 further comprising:
at least one retraction spring extending from the U-shaped section, wherein the retraction spring has:
an application portion; and
a transition portion, wherein the transition portion redirects the application portion from parallel to the brake clip to transverse to the brake clip.
