Wilwood 120-9690-BK DynaPro Single Billet Disc Brake Caliper

The Wilwood DynaPro Single (DPS) billet caliper represents the latest generation in high-performance brake caliper technology, designed as a direct upgrade or replacement for applications previously using the Dynalite Single (DLS) series. These precision-engineered calipers combine exceptional strength with advanced performance features to deliver the most capable "Dyna" series calipers Wilwood has ever produced.

Advanced Billet Construction:

Each caliper is fully CNC machined from premium-grade aluminum alloy billet. The body design incorporates FEA (Finite Element Analysis) engineering with a fortified transition between the piston housings and the bridges. This strengthened critical area substantially increases resistance to deflection and body separation under heavy braking loads. The reduced overall deflection and decreased fluid volume displacement translate directly to improved clamping efficiency with shorter pedal travel.

Performance Enhancements:

• Quick-E-Clip pad retainers support 6812 type brake pads from the top for fast pad service without caliper removal
• Significantly stronger pad retention compared to previous DLS models with single Quick-Clip pin and 7012 type pads
• Heavy wall stainless steel pistons resist corrosion and slow heat transfer from the pads
• Increased piston wall thickness improves pedal firmness and eliminates piston backside deflection for enhanced clamping efficiency
• Replaceable stainless steel SRS bridge plates eliminate bridge wear caused by pad gouging
• Spring-loading action of SRS plates eliminates pad rattle and dampens vibration harmonics that contribute to brake squeal

Versatile Mounting:

Internal fluid passages and four-corner bleed screws allow mounting in any position—front, rear, left, or right side—providing maximum installation flexibility for custom brake system applications.
