Wilwood 120-16505 DynaPro Single Forged Billet Brake Caliper

The Wilwood DynaPro/ST Lug Mount (DP) forged billet caliper represents the latest generation in high-performance brake caliper technology, combining pure race engineering with exclusive Wilwood performance enhancements. This single-piston caliper is precision-engineered for demanding applications where strength, reliability, and stopping power are critical.

Advanced Forging Process:

The DynaPro is stress-flow forged from premium grade billet aluminum, a process that realigns the metal's grain structure within the contour of the body design. This produces a significantly stronger caliper compared to components simply machined from straight-grained billet blocks. The FEA-generated body design features a highly fortified radial transition between the piston housings and bridges, eliminating steps and shoulders that can create weak points. This radius design substantially increases resistance to deflection and body separation under extreme loads.

Key Features:

• Stress-flow forged billet construction for superior strength and durability
• Thermlock pistons minimize heat transfer from pads to brake fluid
• Heavy-wall stainless steel pistons resist corrosion and deflection
• Quick-E-Clip pad retainers allow fast pad service without caliper removal
• Slimmer profile design fits tight clearance applications
• SRS bridge plates eliminate bridge wear from pad gouging and prevent pad rattle
• Internal fluid passages with four-corner bleeder screws
• Compatible with 7812-type brake pads
• Can be mounted in any position: front, rear, left, or right side
• Optional center bridge bolt kit available for additional strength

Performance Benefits:

Structural testing has proven the efficiency of the DynaPro design, with significant reductions in overall deflection and fluid volume displacement. This translates to increased clamping efficiency with less pedal travel, delivering a firm, responsive pedal feel with outstanding stopping power. The heavy-wall stainless steel pistons provide additional strength against backside deflection, maintaining firm pedal feel even at the high pressures generated by power boost systems.

The spring-loading action of the exclusive SRS bridge plates dampens vibration harmonics that contribute to brake squeal during engagement, while extending the service life of the caliper body by preventing pad gouging damage.
