operation. One area targeted for development was caliper bore measurement and inspection. The objective was to increase both the types of calipers that underwent bore inspection as well as the frequency of those inspections with the net result of dramatically increasing caliper bore measurement/ inspection throughput. A brake caliper straddles a brake rotor and houses pistons to which brake pads are affixed. When hydraulic pres- sure is applied by the foot pedal via a brake master cylinder (augmented, if so equipped, by power brake-assist), the pistons squeeze the pads against the rotor to generate stopping friction. The caliper includes cylinder bores into which the pistons fit. A seal must be maintained between the cylinder and the bore to maintain integrity of the hydraulic circuit. This sealing is pro- vided by a piston seal which fits into a groove machined into the cylinder bore. The piston seal itself is a gasket with a square profile on both its ID and OD. The interaction of the seal’s OD against the geometry of the groove in the bore, as well as of its ID against the piston wall is critical—both from the perspective of sealing fluid and also because it is responsible for provid- ing what is called “rollback.” Rollback occurs when the seal deflects as friction with the piston draws the seal in the direction of piston movement (a minute amount); seal edges are designed with chamfers and other details to facilitate this action. The result is that when brak- ing pedal pressure is released, the seal rolls back to its original position, helping to pull the piston with it. This phenom- enon is very important to brake function in terms of noise-related issues attribut- able to pad-to-rotor contact. The Advics Quality Group deter- mined that there are several critical cali- per bore groove features that need to be 12.05
