Wilwood 120-9689 DynaPro Single Billet Disc Brake Caliper Mount - 3.75

The Wilwood DynaPro Single (DPS) billet caliper represents the latest evolution in high-performance brake caliper technology, designed as a direct upgrade or replacement for applications previously using the Dynalite Single (DLS) series. Fully CNC machined from premium-grade aluminum alloy billet, this caliper delivers superior strength and performance enhancements that set a new standard for the "Dyna" series.

Advanced Engineering and Construction:

• FEA-generated body design with fortified transition between piston housings and bridges
• Substantially increased resistance to deflection and body separation under load
• Reduced overall deflection and fluid volume displacement for improved clamping efficiency with less pedal travel
• Heavy wall stainless steel pistons resist corrosion and slow heat transfer from brake pads
• Heavy wall sectional thickness improves pedal firmness and eliminates piston backside deflection

Performance Features:

• Quick-E-Clip pad retainers support 6812 type brake pads from the top for fast pad service without caliper removal
• Substantially stronger pad retention compared to single Quick-Clip pin and 7012 type pads used in previous DLS models
• Replaceable stainless steel SRS (Stainless Rotor Surfaces) 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
• Internal fluid passages with four corner bleed screws allow mounting in any front, rear, left, or right side position

This 3.75" mount spacing caliper combines cutting-edge metallurgy with proven Wilwood engineering to deliver exceptional braking performance, improved durability, and easier serviceability for demanding automotive applications.
