Abstract
A brake assembly that may include a housing assembly, a piston assembly, an operating shaft, and a sensor assembly. The operating shaft may be configured to rotate about an axis to actuate the piston assembly and translate a brake pad assembly from a retracted position to an extended position. The sensor assembly may be configured to detect rotation of the operating shaft.
Claims11
A brake assembly comprising:
- a housing assembly;
- a piston assembly moveably disposed within the housing assembly;
- an operating shaft that is provided with a position feature and that is disposed proximate the housing assembly, wherein the operating shaft rotates about an operating shaft axis to actuate the piston assembly and translate a brake pad assembly from a retracted position to an extended position;
- an adjuster mechanism that is operatively connected to the piston assembly and is configured to adjust the extended position;
- a slide pin assembly upon which the housing assembly translates;
- and
- a sensor assembly that is disposed proximate the housing assembly, the sensor assembly having a first sensor that detects a position of the adjuster mechanism, a second sensor that detects a position of the slide pin assembly, and a third sensor that detects rotation of the operating shaft by detecting a position of the position feature, wherein the first sensor, second sensor, and third sensor are disposed in a single housing.

A brake assembly comprising:
- a housing assembly provided with a piston assembly;
- an operating shaft that is disposed proximate the housing assembly and that has a position feature, wherein the operating shaft is configured to rotate about an operating shaft axis to actuate the piston assembly and translate a brake pad assembly from a retracted position to an extended position;
- an adjuster mechanism operatively coupled to the piston assembly and configured to change the extended position in response to rotation of the operating shaft;
- a slide pin assembly upon which the housing assembly translates when the piston assembly is actuated;
- and
- a sensor assembly disposed proximate the housing assembly, the sensor assembly having a first sensor that detects a position of the adjuster mechanism, a second sensor that detects a position of the slide pin assembly, and a third sensor that detects a position of the position feature and a change in the extended position, wherein the first, second and third sensors are received in a housing and the third sensor is disposed in the housing opposite the first sensor.
