Brake Caliper

The Dyna Pro 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.

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 past pad service without caliper removal, the feature provides substantially stronger retention over the single Quick-Clip pin and 7012 type pads used in the previous DLS models.
