Abstract

A guide assembly for a disc brake. The guide assembly includes a receiving portion of a brake carrier that receives a sleeve portion of a guide pin. The sleeve portion and receiving portion have corresponding non-circular cross-sectional profiles that restrict rotation of the sleeve portion relative to the brake carrier when the sleeve portion is received and aligned in the receiving portion. The present invention further relates to a disc brake that includes a brake carrier, a caliper, and at least one guide assembly and a method of manufacture.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A rotational fixing for a disc brake, the rotational fixing comprising:
 a guide pin having a guide sleeve;   a brake carrier having a receiving portion that receives a portion of the guide sleeve; and   a friction enhancer between the brake carrier and the guide sleeve, wherein the friction enhancer provides frictional engagement between the guide sleeve and the brake carrier such that the friction enhancer restricts rotation of the guide sleeve relative to the brake carrier when the portion of the guide sleeve is received in the receiving portion.   
     
     
         2 . The rotational fixing of  claim 1  wherein the guide sleeve includes a circumferential flange or rim arranged at a first end of the guide sleeve, and the friction enhancer is located on the circumferential flange or rim. 
     
     
         3 . The rotational fixing of  claim 2  wherein the friction enhancer is a knurled surface. 
     
     
         4 . The rotational fixing of  claim 3  wherein the knurled surface is provided on an end face of the circumferential flange or rim. 
     
     
         5 . The rotational fixing of  claim 3  wherein the knurled surface is provided on a circumferentially outer surface of the circumferential flange or rim. 
     
     
         6 . The rotational fixing of  claim 1  wherein the friction enhancer is located on the brake carrier. 
     
     
         7 . The rotational fixing of  claim 6  wherein the friction enhancer is a knurled surface. 
     
     
         8 . The rotational fixing of  claim 1  wherein the friction enhancer includes a washer disposed between the guide sleeve and the receiving portion. 
     
     
         9 . The rotational fixing of  claim 8  wherein the washer is a high friction washer. 
     
     
         10 . The rotational fixing of  claim 8  wherein the washer is a toothed washer.
