Abstract

A brake component assembly includes a support plate and a friction lining mounted to the support plate with a plurality of fasteners. A sealing barrier is formed between the support plate and the friction lining. A liquid material is initially applied to at least one of the support plate and friction lining, which are then fastened together. The liquid material subsequently forms the sealing barrier between the support plate and the friction lining. Optionally, a flexible gasket is used to form the sealing barrier. The flexible gasket is sandwiched between the support plate and friction lining when the support plate and friction lining are fastened together.

Claims

1. A brake component assembly comprising:

a support plate;

a friction lining mounted to said support plate with a plurality of fasteners; and

a liquid material initially applied to at least one of said support plate and friction lining and forming a sealing barrier between said support plate and said friction lining.

2. The brake component assembly according to claim 1 wherein said liquid material comprises a sprayable liquid that is applied to the at least one of said support plate and said friction lining.

3. The brake component assembly according to claim 1 wherein said liquid material comprises a bead of one of an adhesive and a sealant that is applied to cover only a portion of the at least one of said support plate and said friction lining.

4. The brake component assembly according to claim 1 wherein said support plate comprises a dipable component and said liquid material comprises one of an adhesive and a sealant, said dipable component being completely coated with the one of the adhesive and the sealant in a dipping application.

5. The brake component assembly according to claim 1 wherein said liquid material is applied to the at least one of said support plate and said friction lining in a rolling application.

6. The brake component assembly according to claim 1 wherein said sealing barrier comprises a silicon based material.

7. The brake component assembly according to claim 1 wherein said plurality of fasteners extends into said friction lining and said support plate.

8. The brake component assembly according to claim 7 wherein said support plate comprises a brake table having an arcuate surface that corresponds generally to an arcuate surface on said friction material.

9. The brake component assembly according to claim 1 wherein said friction lining comprises at least one lining block comprised of a friction material that has a first arcuate surface, and wherein said support plate comprises a brake table having a second arcuate surface that generally corresponds to said first arcuate surface and a web structure extending away from said second arcuate surface, said web structure being mountable to a brake actuating component.

10. The brake component assembly according to claim 9 wherein said liquid material completely coats said brake table including coating said second arcuate surface and said web structure.

11. The brake component assembly according to claim 9 wherein said liquid material comprises a sprayable liquid that is applied to at least one of said first and said second arcuate surfaces during a spraying application.

12. The brake component assembly according to claim 9 wherein said liquid material is applied to at least one of said first and said second arcuate surfaces during a rolling application.

13. The brake component assembly according to claim 9 wherein said liquid material comprises a bead of at least one of an adhesive and a sealant that is applied to at least one of said first and said second arcuate surfaces.

14. The brake component assembly according to claim 9 wherein said plurality of rivets is solely used for attaching said at least one lining block to said brake table and where said sealing barrier is solely used to provide a sealed interface between said friction material and said brake table.

15. A method of assembling a brake shoe assembly comprising the steps of:

(a) applying a liquid material to at least one of a brake table and friction lining block to form a sealing barrier; and

(b) fastening the friction lining block to the brake table with a plurality of fasteners.

16. The method according to claim 15 wherein step (a) includes spraying the liquid material onto the at least one of the brake table and friction lining block.

17. The method according to claim 15 wherein step (a) includes rolling the liquid material onto the at least one of the brake table and friction lining block.

18. The method according to claim 15 wherein step (a) includes applying the liquid material onto the at least one of the brake table and friction lining block as a bead of material.

19. The method according to claim 18 including the step of causing the bead of material to flow in a plurality of directions to cover a greater portion of the at least one of the brake table and friction lining block during step (b).

20. The method according to claim 15 wherein the brake table includes a plate portion with an arcuate surface for receiving the friction lining block and a web structure extending outwardly from the plate portion, and wherein step (a) includes dipping the support plate into the liquid material to completely coat the plate portion and the web structure.

21. A method for re-fitting a brake component assembly comprising the steps of:

(a) removing a worn lining block from a brake table;

(b) applying a liquid material to at least one of a new lining block and the brake table to form a sealing barrier; and

(c) fastening the new lining block to the brake table.

22. The method according to claim 21 wherein step (b) includes spraying the liquid material onto the one of the new lining block and the brake table.

23. The method according to claim 21 wherein step (b) includes dipping the at least one of the new lining block and the brake table in the liquid material.

24. The method according to claim 21 wherein step (b) includes rolling the liquid material onto the one of the new lining block and the brake table.

25. The method according to claim 21 wherein step (b) includes applying a bead of liquid material onto the one of the new lining block and the brake table.

26. The method according to claim 21 wherein the liquid material is a silicon based material.

27. A brake component assembly comprises:

a support plate;

a friction lining mounted to said support plate with a plurality of fasteners; and

a sealing barrier positioned between said support plate and said friction lining, said sealing barrier comprising a flexible gasket that is solely used to provide a sealed interface between said friction lining and said support plate.

28. The brake component assembly according to claim 27 wherein said gasket comprises a non-asbestos resilient material.

29. The brake component assembly according to claim 28 wherein said non-asbestos resilient material comprises one of a rubber material and a cork material.

30. A method for assembling a brake shoe assembly comprising the steps of:
