Overview
The Baer Brakes Pro Plus 4262239FR is a rear disc brake kit for Ford 8.8 Inch C-clip rear ends, with a Fire Red caliper finish. Its 6-piston, 6P caliper clamps a 14 inch, 2-piece slotted, drilled and zinc plated rotor, and the kit is sold as a complete set.
The backing plate doubles as the caliper mount and houses a modern 1-piece park brake shoe assembly. Baer rates the 14 inch Pro Plus rotor for wheels of 18 inch or larger, and it runs the widely used D0731 pad type.
Key features
- Six-piston 6P caliper with staggered pistons that help even out pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc plated rotor on a billet aluminum hat
- Rotors arrive pre-assembled with NAS high grade stainless hardware
- CNC machined from US sourced forged or billet aluminum with a powder coated finish
- Stainless braided hoses and hardware included
Choosing a rotor size
A six-piston caliper clamps with more pad area than a single or two-piston design, which spreads heat and pressure across the pad. Staggered pistons are meant to balance wear over the life of the pad, but pads still need regular checks because compound and driving style set how fast they wear.
A two-piece rotor relies on its hat and fasteners staying tight. Before the first drive, confirm the hardware is seated and torqued to the vehicle’s specification. Check rotor runout and hub surface cleanliness, since a dirty mounting face can cause vibration that feels like a warped rotor.
Brake fluid and hoses deserve attention on any upgrade. Steel braided hoses resist swelling under pressure but can still chafe where they rub against brackets. Inspect them at every service, look for weeping at the fittings, and replace fluid on a regular interval. Park brake shoes in a backing plate design should be checked for adjustment whenever the cable is serviced.
- Pad compound affects bite and dust
- Torque hardware to specification
- Check hoses for chafing
- Watch for vibration after install
- Keep the mounting face clean
