Overview
The Baer Brakes 4262261CY is a complete SS4 rear brake system in Comp Yellow, designed around the early big bearing housing ends of a Ford 9 inch rear. It pairs a 4-piston S4 caliper with a 12 inch, one-piece slotted, drilled and zinc-plated rotor, and it is supplied as a kit with a park brake built into the backing plate.
The backing plate serves as the caliper mount and houses a modern one-piece park brake shoe assembly, so the parking brake is part of the rear setup. Braided brake hoses come with the kit. The system is made for 5 lug wheels on a 5×5.00 bolt pattern. The 12 inch SS4 is intended for wheels 16 inch or larger.
Key features
- 4-piston S4 caliper, two-piece design, made in Phoenix, Arizona
- Caliper body CNC machined from US sourced forged or billet aluminum
- Powder coated Comp Yellow finish
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- One-piece slotted, drilled, zinc-plated rotor, 12 inch diameter
- Pads are DR1-C FMSI, with the DR1 or HB100 pad type.
Choosing a rear brake setup
A rear disc kit changes more than stopping force, so it helps to look at the whole assembly before the parts go on. The caliper, rotor and backing plate must clear the wheel barrel, the spokes and the suspension at full travel. Many owners who replace a rear brake system also check the wheel bearings, axle seals and brake lines during the same job, because those parts are reached with the hub and backing plate removed.
A parking brake built into the backing plate ties the hand brake to the rear service hardware. Shoe wear, adjustment and lever travel therefore show up in the same area as pad and rotor wear, so note the condition of the shoes when the rotor comes off. Keep a record of the pad and rotor part numbers so replacements match the original setup.
- Check pad thickness and wear pattern at every tire rotation
- Look for heat cracks, deep grooves or a blued rotor face
- Confirm the caliper pistons move freely and the boots are intact
- Inspect braided hoses for chafing, swelling or seepage at the fittings

Vehicle fitment
It mounts to the Ford 9 inch early big bearing axle flange with a 5 lug, 5×5.00 wheel pattern. Compare your vehicle’s year, model and trim with the axle before buying.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Lay the S113E template against your wheel before mounting, since Baer cannot guarantee fit to every wheel style and the rotor is 12 inch. Because the park brake shoes sit inside the backing plate, plan to set the parking brake during the same job. Brakes are safety-critical, so have the finished installation checked before the vehicle is driven.
What’s included
The kit includes the S4 caliper, the 12 inch rotor, the backing plate with its one-piece park brake shoe assembly, and braided brake hoses.
Not included: park brake cables.
