DYNAPRO LUG MOUNT
CALIPER WITH DUST BOOTS
Caliper Highlights:
This model of the Dynapro lug mount caliper was
developed for applications that require or prefer a
dust-booted piston. Dust-booted aluminum pistons
provide added protection against road or track born
dirt and debris on low to intermediate temperature
range applications that may also operate in harsh
environments. The pistons are clear anodized to
eliminate corrosion while providing added lubricity for
drag-free operation within the bores. The dust boots
work in conjunction with high-temperature square faced
internal seals in the caliper bores to provide optimum
performance, ultimate reliability, and quick turn around at pad
service intervals.
The strength and performance of the DynaPro caliper are a combination of process and design. The caliper bodies
are stress-flow forged from premium grade billet aluminum. Stress-flow forging realigns the grain structure of the metal
within the shape and contour of the caliper body. This process produces a part with superior strength over parts simply
machined from straight-grained blocks of billet. The body design in itself is a product of computer generated modeling
and stress analysis technology. It features a highly fortified radial transition between the caliper end bridges and the
main body piston bore housings. The radial transition eliminates all sharply machined steps and shoulders in this
critical area to substantially increase resistance to deflection and caliper 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 is loaded with other enhancements for performance and durability. The calipers feature Quick-E-Clip
pad retainers that support a 7812 type brake pad from the top. Not only does it allow for fast pad service without caliper
removal, the bottom pad supports have been removed to create a slimmer profile that can be more easily fitted into
tight clearance applications. An optional bridge bolt kit, P/N 230-10188 is also available to provide additional body
strength and fortified pad retention in the center of the caliper bridge for extreme high pressure, high load applications.
Each DynaPro is also fitted with stainless SRS bridge plates. SRS plates eliminate the abutment 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 can contribute to pad squeal and other harsh noise
during engagement. The caliper is completed with internal fluid passages and four corner bleed screws that facilitate
installation in any right or left hand, leading or trailing mounting position. The calipers are then finished with either our
brake fluid resistant powder coated colors, or fully polished and branded with our Wilwood signature logo.
