This Wilwood Dynapro DPR-DS is a four-piston radial-mount caliper with stainless steel pistons and integrated dust wiper seals, so the pistons stay protected from road grit. The caliper has four pistons, a stainless piston type, a dust boot, a forged aluminum body, and a 4.3 lb weight. The manufacturer says the design pairs radial mounting with a slim profile and strong, durable construction for harsh conditions. Compared with a standard caliper, the sealed pistons suit muddy, gravel, or wet-weather track days, and the 1.25 in piston diameter gives a larger clamping footprint for track or strip use. This red powder-coated version fits builds that call for a color-matched caliper.
Fitment is universal. The manufacturer lists a 5.98 in mount center with a maximum rotor diameter of 12.19 in and a 0.50 in rotor width, so confirm bracket, hub, and rotor compatibility with the manufacturer before ordering. For the install, begin bleeding with the caliper farthest from the master cylinder. On calipers with two top bleed screws, bleed the outboard screw first, then the inboard. Never bleed the lower screws that point downward. Searches for Wilwood Dynapro DPR-DS 120-14698-RD, radial mount dust seal caliper, and 12.19 rotor brake upgrade match this part.
No. The manufacturer lists this caliper as a universal radial-mount unit, so you must match the bracket, hub, and rotor size to your application. Confirm compatibility with the manufacturer before ordering.
The manufacturer's listing shows the -RD number as a red powder coat finish, while the base part number is listed with a Type III anodize finish.
This is a job for someone experienced with disc brake systems, since the caliper must be mounted, bled, and checked for clearance. The manufacturer's general bleeding guidance applies here: most Wilwood calipers have two bleed nipples and some have four. Bleed the system with an assistant or a vacuum bleeder, keep fluid in the reservoir, and inspect for leaks before driving. Use Wilwood-recommended fluid and verify the mounting torque and hose fittings for this specific caliper with the manufacturer.
