Total Control: Performance Machine Classic Rear Caliper Kit (1987–1999 Softail)

Bring your Evolution Softail’s braking performance into the modern era with the Performance Machine Classic Rear Caliper Kit. The factory rear brakes on 1987–1999 Softails are notorious for their lack of feel and prone-to-fade performance. PM solves this with a race-inspired 4-piston design that provides the confidence-inspiring bite you need for modern roads.
Engineered Specifically for the Evo Softail

This isn’t a “universal” fit—it is a chassis-specific solution designed to bolt directly to your classic Softail swingarm:

Complete Bolt-On Kit: This package includes both the high-performance 4-piston caliper and the application-specific mounting bracket. It is designed to work seamlessly with your factory 11.5″ rear rotor and 3/4″ axle.

Superior Clamping Force: The 4-piston configuration offers significantly more surface area and pressure than the original single-piston factory unit. This results in shorter stopping distances and a much more linear, predictable response from your rear brake pedal.

Billet Aluminum Rigidity: CNC-machined from a solid block of 6061-T6 billet aluminum, the PM caliper is far more rigid than cast factory units. This stiffness eliminates “pedal mush,” ensuring every bit of pressure is converted into stopping power.

Iconic PM Style and Quality

Clean Aesthetic: The “Classic” series features a smooth, timeless design that complements the lines of a vintage Softail, whether it’s a Heritage, Fat Boy, or Custom.

Finish Options: Available in Show-Quality Chrome, Black Ops (matte black), or Contrast Cut to match your bike’s specific look.

Differential Bore Technology: Like PM’s front calipers, this rear unit utilizes staggered piston sizes to ensure the brake pads wear evenly and maintain a consistent “bite” over their entire lifespan.

Technical Specifications

Fitment: Fits 1987–1999 Harley-Davidson Softail models (FXST/FLST).

Rotor Compatibility: Designed for use with standard 11.5″ rear rotors.

Ready to Install: Includes high-friction brake pads and all necessary hardware for a clean installation.

Brake Line Note: May require a custom brake line depending on your current setup.

Don’t let outdated braking technology hold you back. The Performance Machine Rear Caliper Kit is the most trusted way to add safety and elite style to your 1987–1999 Softail.
