This kit will provide everything you need for the braking system on a Stallard SST chassis. Allows an option for both standard setup, and quick disconnect setup to allow for easier front end and rear end changes. 


Left Front Caliper

This two piston front brake caliper is specifically designed for use with Micro Sprint racing applications. Its mounting ears extend directly to the spindle so no adapter plate is needed.

  • Two 1" pistons
  • 2.125" bolt spacing
  • Brake pads are included

Note: It will not clear a normal wheel half unless a big bell wheel half (deep dish) is used with this caliper.


Rear Caliper

The Dyna Pro Single (DPS) billet caliper is the newest generation of calipers available as an upgrade or replacement for applications previously using the Dynalite Single (DLS) series. DPS calipers combine superior strength with performance enhancements to make these the best "Dyna" series calipers ever.

The DPS is loaded with exclusive Wilwood performance enhancements. The calipers feature Quick-E-Clip pad retainers that support a 6812 type brake pad from the top. In addition to past pad service without caliper removal, the feature provides substantially stronger retention over the single Quick-Clip pin and 7012 type pads used in the previous DLS models.

  • Quick-E-Clip pad retainers supports brake pad from top
  • Heavy wall stainless steel pistons
  • Stainless steel SRS bridge plates eliminate pad rattle and dampen vibration
  • Internal fluid passages
  • Four corner bleed screws allow mounting in any front, rear, left, or right side position


Wilwood Brake Pads

  • A very high friction pad with aggressive initial response
  • Immediate low tempeature response
  • Low wear rate
  • Improved friction formula for heavy braking asphalt ovals, extreme braking on dirt, and all types of off-road and road course applications
  • Predictable and linear response with excellent modulation on iron and titanium rotors
  • Long wear rates with iron and steel rotors
  • High torque on Titanium rotors
  • Very high heat fade resistance


Quick Connectors

Aluminum brake line quick disconnects. This quick disconnect was designed to be used with brake fluid. 

  • -03AN fitting size
  • Both male and female fitting included
