Abstract

A disc brake assembly having an anchor bracket, a disc type of service brake assembly having a first brake caliper configured to be secured to the anchor bracket; and an electric disc type of parking and emergency brake assembly having a second brake caliper configured to be secured to the anchor bracket.

Claims

1. A disc brake assembly comprising:

an anchor bracket;

a disc type of service brake assembly having a first brake caliper configured to be secured to the anchor bracket; and

an electric disc type of parking and emergency brake assembly having a second brake caliper configured to be secured to the anchor bracket.

2. The disc brake assembly of claim 1 wherein the anchor bracket includes a first plurality of openings for operatively securing the anchor bracket to an associated component of a vehicle, a second plurality of openings for operatively securing the first brake caliper of the service brake assembly to the anchor bracket, and a third plurality of openings for operatively securing the second brake caliper of the parking and emergency brake assembly to the anchor bracket.

3. The disc brake assembly of claim 1 wherein an electric actuator unit is configured to be operatively secured to the second brake caliper of the parking and emergency brake assembly in order to selectively operate the parking and emergency brake assembly.

4. The disc brake assembly of claim 1 wherein the second brake caliper of the parking and emergency brake assembly is configured to be slidably supported relative to the anchor bracket by a pair of guide pins.

5. The disc brake assembly of claim 1 wherein the parking and emergency brake assembly includes an inboard brake pad and an outboard brake pad, the inboard brake pad and the outboard brake pad being configured to be operatively carried relative to the second brake caliper by separate and distinct members.

6. The disc brake assembly of claim 5 wherein the inboard brake pad is configured to be operatively carried by a pair of abutment pins, the abutments pins configured to be disposed in openings provided in the anchor bracket and openings provided in the inboard brake pad.

7. The disc brake assembly of claim 6 wherein at least one spring is configured to be operatively connected to one of the abutment pins and the inboard brake pad to thereby prevent off-brake rattle.

8. The disc brake assembly of claim 7 wherein the inboard brake pad includes an impression which is configured to receive a leg of the at least one spring.

9. The disc brake assembly of claim 1 wherein the outboard brake pad is configured to be operatively carried by a pair of fingers of the first brake caliper.

10. The disc brake assembly of claim 9 wherein the outboard brake pad includes a pair of semi-pierce holes which are configured to line up and extend through through holes provided in the fingers, and wherein a spring is configured to be attached to the outboard brake pad and abut against the fingers to thereby attach the outboard brake pad to the first brake caliper.

11. A disc brake assembly comprising:

an anchor bracket having a first plurality of openings for operatively securing the anchor bracket to an associated component of a vehicle;

a disc type of service brake assembly having a first brake caliper configured to be secured to the anchor bracket, wherein the anchor bracket includes a second plurality of openings for operatively securing the first brake caliper of the service brake assembly to the anchor bracket;

an electric disc type of parking and emergency brake assembly having a second brake caliper configured to be secured to the anchor bracket, wherein the anchor bracket includes a third plurality of openings for operatively securing the second brake caliper of the parking and emergency brake assembly to the anchor bracket, wherein the second brake caliper is configured to be slidably supported relative to the anchor bracket by a pair of guide pins; and

an electric actuator unit configured to be operatively secured to the second brake caliper of the parking and emergency brake assembly, wherein the electric actuator unit is configured to be selectively operated to actuate the parking and emergency brake assembly.

12. The disc brake assembly of claim 11 wherein the parking and emergency brake assembly includes an inboard brake pad and an outboard brake pad, the inboard brake pad and the outboard brake pad being configured to be operatively carried relative to the second brake caliper by separate and distinct members.

13. The disc brake assembly of claim 12 wherein the inboard brake pad is configured to be operatively carried by a pair of abutment pins, the abutments pins configured to be disposed in openings provided in the anchor bracket and openings provided in the inboard brake pad.

14. The disc brake assembly of claim 13 wherein at least one spring is configured to be operatively connected to one of the abutment pins and the inboard brake pad to thereby prevent off-brake rattle.

15. The disc brake assembly of claim 14 wherein the inboard brake pad includes an impression which is configured to receive a leg of the at least one spring.

16. The disc brake assembly of claim 11 wherein the outboard brake pad is configured to be operatively carried by a pair of fingers of the first brake caliper.

17. The disc brake assembly of claim 16 wherein the outboard brake pad includes a pair of semi-pierce holes which are configured to line up and extend through through holes provided in the fingers, and wherein a spring is configured to be attached to the outboard brake pad and abut against the fingers to thereby attach the outboard brake pad to the first brake caliper.

18. A disc brake assembly comprising:

an anchor bracket;

a disc type of service brake assembly having a first brake caliper configured to be secured to the anchor bracket;

an electric disc type of parking and emergency brake assembly having a second brake caliper configured to be secured to the anchor bracket; and

an electric actuator unit configured to be operatively secured to the second brake caliper of the parking and emergency brake assembly in order to selectively operate the parking and emergency brake assembly;

wherein the parking and emergency brake assembly includes an inboard brake pad and an outboard brake pad, the inboard brake pad and the outboard brake pad being configured to be operatively carried relative to the second brake caliper by separate and distinct members.

19. The disc brake assembly of claim 18 wherein the inboard brake pad is configured to be operatively carried by a pair of abutment pins, the abutments pins configured to be disposed in openings provided in the anchor bracket and openings provided in the inboard brake pad.

21. The disc brake assembly of claim 19 wherein at least one spring is configured to be operatively connected to one of the abutment pins and the inboard brake pad to thereby prevent off-brake rattle.

22. The disc brake assembly of claim 18 wherein the outboard brake pad is configured to be operatively carried by a pair of fingers of the first brake caliper.

23. The disc brake assembly of claim 22 wherein the outboard brake pad includes a pair of semi-pierce holes which are configured to line up and extend through through holes provided in the fingers, and wherein a spring is configured to be attached to the outboard brake pad and abut against the fingers to thereby attach the outboard brake pad to the first brake caliper.
