Abstract

A method of making a brake assembly. The method may include providing a brake pad carrier, an air operated brake actuator suitable for attaching to the brake pad carrier, and a hydraulically operated brake actuator suitable for attaching to the brake pad carrier, and attaching one of the air operated brake actuator and hydraulically operated brake actuator to the brake pad carrier to provide a brake assembly.

First claim

What is claimed is:

1. A method of making a first brake assembly and a second brake assembly comprising:
a) providing a first bare casting;
b) providing a second bare casting having a same configuration as the first bare casting;
c) providing a first housing and receiving an air operated brake actuator in the first housing;
d) providing a second housing and receiving a hydraulically operated brake actuator in the second housing;
e) providing a first bridge that has an attachment feature, wherein the first housing and the second housing are attachable to the attachment feature of the first bridge;
f) providing a second bridge that has an attachment feature, wherein the first housing and the second housing are attachable to the attachment feature of the second bridge;
g) machining the first bare casting in a first manner to produce a first brake pad carrier, the first manner being suitable for attaching the air operated actuator;
h) machining the second bare casting in a second manner to produce a second brake pad carrier, the second manner being suitable for attaching the hydraulically operated brake actuator;
i) attaching the first housing to the attachment feature of the first bridge and to the first brake pad carrier, thereby providing the first brake assembly; and
j) attaching the second housing to the attachment feature of the second bridge and to the second brake pad carrier, thereby providing the second brake assembly.

2. The method of claim 1 wherein the first bridge has a body for engaging a brake pad, a first arm extending from a first end of the body, and a second arm extending from a second end of the body.

3. A method of making a brake assembly comprising:
a) providing a brake pad carrier;
b) providing one air operated brake actuator;
c) providing a first housing and receiving the air operated brake actuator in the first housing;
d) providing one hydraulically operated brake actuator;
e) providing a second housing and receiving the hydraulically operated brake actuator in the second housing;
f) providing a bridge for engaging a brake pad, wherein the bridge has an attachment feature, and wherein the first housing and the second housing are attachable to the attachment feature; and
g) attaching only one of the first housing and the second housing to the brake pad carrier and to the bridge to provide the brake assembly.

4. The method of claim 3 wherein the bridge has a body for engaging a brake pad, a first arm extending from a first end of the body, and a second arm extending from a second end of the body.

5. The method of claim 3 wherein the bridge comprises a body for engaging a brake pad, a first arm extending from a first end of the body and a second arm extending from a second end of the body, and wherein the first arm, the second arm, or the first arm and the second arm includes the attachment feature.
