Description

MCP Mini-Lite Brake Caliper Assembly – 1125BB Dual-Piston


Martin Custom Products (MCP) is a trusted leader in high-performance brake systems for small engine motorsports. The MCP Mini-Lite 1125BB Billet Caliper is a compact, lightweight solution built for precision braking on low to mid-powered race applications where weight savings and throttle response matter.


Designed for Versatility & Performance

This caliper features dual 1-1/8" bore pistons housed in a two-piece billet aluminum body. It’s engineered to work with rotors between .125" and .187" thick, making it ideal for a wide range of vehicles and classes, from karts to Jr. Dragsters.


Popular Applications:

  • Micro Sprints & Mini-Sprints
  • Quarter Midgets & Mini-Cup Cars
  • Racing Go-Karts & Recreational Karts
  • Jr. Dragsters & Racing Lawn Mowers
  • Custom builds: Racing Barstools, Pit Bikes, and more


Compact & Lightweight for Spec/Low HP Classes

The Mini-Lite series uses smaller brake pads, reducing surface area and braking force. This controlled braking capability is ideal for:

  • Stock & spec engine classes
  • Low-horsepower divisions
  • Tracks with minimal braking zones

Lighter calipers mean reduced rotating mass on the rear axle, helping improve acceleration and responsiveness—critical for competitive performance in limited power classes.


Technical Specifications:

  • Piston Bore: Dual 1-1/8"
  • Rotor Compatibility: .125" to .187" thick
  • Mounting Bolt Spacing: 1.875" center-to-center
  • Bolt Size: Fits 5/16" bolts
  • Brake Fluid: DOT 5 only
  • Pads Included: Yes (Mini-Lite friction compound)


Why Choose MCP Mini-Lite?

  • Precision-machined billet aluminum body
  • Designed for weight savings and optimal balance
  • Trusted across hundreds of motorsports platforms
  • Ideal balance of braking performance and acceleration gain

FAQ

What vehicles does the MCP Mini-Lite Brake Caliper fit?

This caliper is commonly used on racing go-karts, quarter midgets, mini sprints, Jr. dragsters, and racing lawn mowers. It’s ideal for low- to mid-power racing applications.


What rotor thicknesses does it support?

The MCP Mini-Lite caliper is compatible with brake rotors between .125" and .187" thick.


What brake fluid should I use?

This caliper is only compatible with DOT 5 brake fluid. Using other types may damage internal seals.


Are brake pads included?

Yes, the MCP Mini-Lite comes with pads pre-installed and ready for use.


How does this caliper differ from standard MCP calipers?

The Mini-Lite features smaller brake pads, offering reduced braking surface area. This is beneficial in stock or spec classes where lower braking force, less weight, and quicker acceleration are preferred.


Can this caliper be used on the rear axle only?

Yes. In low-horsepower or short-track setups, the Mini-Lite is often used on the rear axle to reduce rotational mass and increase throttle responsiveness.
