Abstract

A brake clip for a disc brake assembly having a brake pad received in an anchor bracket includes a shim configured to be received in the anchor bracket. The shim includes a base leg and opposing upper and lower legs extending from the base leg to define a receiving space. At least one of the upper and lower legs includes a retaining member extending in a first direction. A spring is provided in the receiving space for receiving the brake pad. The spring includes a base and a pair of projections extending from the base. At least one of the projections includes a retaining member that cooperates with the at least one retaining member on the shim to allow for a predetermined amount of relative movement between the shim and the spring in the first direction.

First claim

What is claimed is:

1. A brake clip for a disc brake assembly having a brake pad received in an anchor bracket, comprising:
a shim configured to be received in the anchor bracket and having a base leg and opposing upper and lower legs extending from the base leg to define a receiving space, at least one of the upper and lower legs including a retaining member extending in a first direction over less than the entire length of the at least one of the upper and lower legs; and
a spring provided in the receiving space for receiving the brake pad, the spring including a base and a pair of projections extending from the base and being slidably engaged with the respective upper and lower legs on the shim, at least one of the projections including a retaining member extending in the first direction over less than the entire length of the at least one projection and cooperating with the at least one retaining member on the shim to allow for a predetermined amount of relative movement between the retaining members of the shim and the spring in the first direction during operation of the disc brake assembly.

2. The brake clip recited in claim 1 , wherein the retaining members prevent relative movement between the shim and the spring in a second direction extending perpendicular to the first direction.

3. The brake clip recited in claim 2 , further comprising cooperating alignment members provided on the shim and the spring for preventing relative movement between the shim and spring in the second direction, the alignment members on the shim extending the entire length of the shim and the alignment members on the spring extending the entire length of the spring.

4. The brake clip recited in claim 3 , wherein the alignment members comprise cooperating ribs provided on the shim and the spring.

5. The brake clip recited in claim 1 , wherein each retaining member on the shim comprises an opening and each retaining member on the spring comprises a rib extending into and movable within the corresponding opening in the shim during operation of the disc brake assembly.

6. The brake clip recited in claim 1 , wherein each retaining member on the spring comprises a rib and each retaining member on the shim comprises a rib received by the corresponding rib of the spring such that each rib on the spring slides over and relative to the corresponding rib on the shim during operation of the disc brake assembly.

7. The brake clip recited in claim 1 , wherein each retaining member on the spring comprises an opening and each retaining member on the shim comprises a rib extending into and movable within the corresponding opening in the spring during operation of the disc brake assembly.

8. The brake clip recited in claim 1 , further comprising a coating provided on the shim and the spring for reducing sliding friction therebetween.

9. A device for a disc brake assembly having first and second brake pads received in first and second anchor brackets, comprising:
a first brake clip configured to be received in the first anchor bracket and having a base leg and opposing upper and lower legs extending from the base leg to define a receiving space therebetween for receiving the first brake pad;
a second brake clip configured to be received in the second anchor bracket and having a base leg and opposing upper and lower legs extending from the base leg to define a receiving space therebetween for receiving the second brake pad; and
a pad separator for connecting to the first and second brake pads for controlling relative movement therebetween, wherein the pad separator includes a base spanning the entire distance between the first and second brake clips and a pair of legs extending from opposite ends of the base, each of the legs being secured to a portion of one of the first and second brake clips such that movement of the portions of the first and second brake clips relative to one another moves the legs of the pad separator relative to one another, and wherein the base includes a spring portion that allows for a predetermined amount of relative movement between the legs and allows the length of the base to change during operation of the disc brake assembly.

10. The device recited in claim 9 , wherein the pad separator is secured to the first and second brake clips for controlling relative movement between the first and second brake clips.

11. The device recited in claim 10 , wherein each of the first and second brake clips includes at least opening through which the pad separator extends for securing the pad separator directly to the first and second brake clips.

12. The device recited in claim 9 , wherein the spring portion prevents movement of the legs towards one another once the predetermined amount of relative movement is reached.

13. The device recited in claim 9 , wherein each of the first and second brake clips comprises:
a shim configured to be received in the respective anchor bracket and defining the legs and the receiving space, each of the upper and lower legs including a retaining member extending in a first direction; and
a spring provided in the receiving space for receiving the brake pad, the spring including a base and a pair of projections extending from the base, each of the projections including a retaining member that cooperates with one of the retaining members on the shim to allow for a predetermined amount of relative movement between the shim and the spring in the first direction.

14. The device recited in claim 13 , wherein the retaining members prevent relative movement between the shim and the spring in a second direction extending perpendicular to the first direction.

15. The device recited in claim 14 , further comprising cooperating alignment members provided on the shim and the spring for preventing relative movement between the shim and spring in the second direction, the alignment members on the shim extending the entire length of the shim and the alignment members on the spring extending the entire length of the spring.

16. The device recited in claim 13 , wherein the retaining members on the shim comprise openings and the retaining members on the spring comprise ribs extending into and movable within the openings in the shim during operation of the disc brake assembly.

17. The device recited in claim 9 , wherein the pad separator is secured to first and second backing plates connected to the first and second brake pads.
