StopTech ST40 Caliper SR34 Compound Race Brake Pads
SR34 Compound
- Superior pedal feel and modulation characteristics
- Formulated for high initial bite
- Slight torque rise with temperature
- Extremely low pad and abraded disc wear
- All purpose pad for high grip, high power applications
The STR-40 is the most versatile caliper in the StopTech lineup. Widely used in StopTech Big Brake Kit offerings, the STR-40's versatility is optimized through an extensive selection of piston size combinations to provide precise force output for each application. Internal cross-over passages and dust boots further extend the versatility of the STR-40 into uses such as the popular STOR-40 Off-Road caliper.
- MIL-spec hard anodizing on calipers resists color change or fading
- Forged and weight-optimized, up to 20 percent lighter than standard calipers
- Stiffest calipers available with patented strengthening bridge for improved pedal feel and modulation
- Eliminates pad taper wear and provides consistent, confidence-inspiring performance
- Calipers and piston sizing specifically matched to each application

StopTech® introduces a new line of StopTech® Racing Friction Materials that brings the company's "Brake Late, Finish First" philosophy to a wide range of racing disciplines. The pads complement the company's wide range of high performance and replacement brake friction.
The new race-specific pads are engineered to provide optimal friction levels for shorter stops, increased control through superior pedal modulation, and fade-free performance at extreme racing temperatures. StopTech® Racing pads are designed to provide superior performance in any racing brake system and engineered to match the outstanding performance capabilities expected of all StopTech® Racing Balanced Brake Systems.
StopTech's® unique metallic compounds are blended with carbon and graphite particles to provide an optimal high temperature race friction material. The result is smoother, more predictable and more consistent brake engagement along with exceptional release characteristics not found in most other racing friction materials.
