DYNAPRO SINGLE
BILLET CALIPER
Caliper Highlights:
The DynaPro Single (DPS) billet caliper represents
the newest generation of calipers available as an
upgrade or replacement for applications previously
using the long-standing Dynalite Single (DLS) model
series. DPS calipers combine superior strength with
several new performance enhancements to make
these the best "Dyna" series calipers ever built.
The strength of the DynaPro Single is a
combination of process and design. DPS calipers
are fully CNC machined from premium grade alloy
billet. The FEA generated body design incorporates a
highly fortified transition between the piston housings and
the bridges. Strengthening this critical area of the caliper has
substantially increased its resistance to deflection and body
separation under load. Structural deflection and volume
displacement testing have proven the efficiency of this innovative design.
Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased
clamping efficiency with less pedal travel. The bottom line is a firm, responsive pedal with outstanding stopping power.
The DynaPro Single is loaded with other 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 at higher system pressures.
Every DPS caliper is also fitted with replaceable stainless steel SRS bridge plates. SRS plates eliminate the bridge
wear caused by pad gouging to extend the service life of the caliper body. The spring-loading action of the SRS plates
also 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.
