Project Summary
Overview
Consistent piston retraction is a reoccurring problem in the caliper assembly. This causes brake pad sticking which induces severe heat, causing heat related damages to the brake assembly. The damage creates costly repairs and months of delays in testing. Thus, creating the need for a piston retraction mechanism.
Objectives
Design a piston retraction system that augments the existing caliper assembly by incorporating an internal mechanism that ensures full piston retraction.
Approach
- Researched existing brake assemblies through patents and current products available on the market
- Generated possible piston retraction mechanisms and revised designs
- Developed designs for assembly components
- Selected component materials using Granta software
- Validated component dimensions through use of hand calculations
- Manufactured a 1:1 ratio prototype of the piston retraction mechanism and caliper assembly
- Conducted functionality testing of the prototype
Outcomes
- The design applies a 25lbs retraction force to the piston
- The design operates internally within the brake caliper assembly
- The design ensures full piston retraction and eliminates costly damage to the entire brake assembly
