Wilwood 120-9687 Details

The DynaPro Single (DPS) billet caliper is the newest generation of calipers available as an upgrade or replacement for applications previously using the Dynalite Single (DLS) series. DPS calipers combine superior strength with performance enhancements to make these the best "Dyna" series calipers ever. Calipers are fully CNC machined from premium grade alloy billet. The FEA generated body design incorporates a fortified transition between the piston housings and the bridges. Strengthening this critical area has substantially increased its resistance to deflection and body separation under load. Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The DPS is loaded with exclusive Wilwood performance enhancements. The calipers feature Quick-E-Clip pad retainers that support a 6812 type brake pad from the top. In addition to fast pad service without caliper removal, this feature provides substantially stronger retention over the single Quick-Clip pin and 7012 type pads used in the previous DLS models. The DPS uses heavy wall stainless steel pistons to resist corrosion and slow the heat transfer from the pads. The heavy wall sectional thickness improves pedal firmness and adds to the overall clamping efficiency by eliminating piston backside deflection. Calipers are fitted with replaceable stainless steel SRS bridge plates. SRS plates eliminate bridge wear caused by pad gouging. The spring-loading action of the SRS plates eliminates pad rattle and dampens the vibration harmonics that contribute to squeal during engagement. The package is completed with internal fluid passages and four corner bleed screws that allow mounting in any front, rear, left, or right side position.
