Overview
The Baer Brakes 4262689FR is an SS4 Plus 11-inch rear brake kit with a Fire Red four-piston S4 caliper. It suits rear ends with Ford 9 inch early big bearing housing ends and uses an 11-inch two-piece rotor with slotted, drilled and zinc-plated friction surfaces.
The kit is intended for wheels 15 inches and larger. Its rotors are pre-assembled with NAS high grade stainless hardware, and the mounting brackets, stainless braided hoses and hardware are all packed with the kit. Baer advises checking wheel clearance with its S125A template, since it cannot guarantee fit to every wheel style.
Key features
- Fire Red finish on the S4 caliper
- Two-piece vented rotor at 11.0 inch outside diameter
- Billet aluminum rotor hat
- Surface slotted, drilled and zinc plated for the rotor face
- Hard anodized aluminum pistons and stainless steel abutments
- Noise suppression clips and dual seals against dust, weather and pressure
- Forged or billet aluminum parts CNC machined in the USA
- Stainless braided hoses approved to DOT standards
Caring for the finish and fasteners
Fire Red powder coating protects the caliper body from corrosion and road debris, but the coating can chip under stone strikes and wheel contact. Touch up damaged areas after cleaning the surface, and avoid heat-sensitive coatings near the pads. The finish is cosmetic, so it does not change the friction or clamping behavior of the system.
Bolts that hold the caliper bracket and rotor hat carry the braking load, so they deserve regular checks. Tighten fasteners to the torque your installer or service procedure requires rather than guessing, and recheck them after the first few drives. Re-torque after any brake service to keep the caliper seated and the rotor running true.
- Touch up chips on the caliper body after cleaning
- Use a torque wrench on caliper bracket and hat bolts
- Recheck fasteners after the first few drives
