Overview
The Baer Brakes 4262241CY is a complete rear disc brake kit for Ford 8.8 inch C-clip rear ends with a 2.5 inch axle standoff and a 5 lug, 5×4.50 wheel pattern. It combines an S4 four-piston caliper in Comp Yellow with a 12 inch one-piece slotted, drilled and zinc plated rotor, plus a park brake shoe assembly housed inside Baer’s backing plate.
This kit suits owners who want a rear disc brake upgrade on a Ford 8.8 axle. The 12 inch rotor is intended for wheels of 16 inch or larger, but wheel fit varies by style, so check the S113E template against the wheel you plan to use. The kit is matched to an axle flange rather than a named vehicle, so confirm your axle type and wheel clearance first.
Key features
- S4 two-piece, four-piston floating caliper in Comp Yellow
- Caliper components CNC machined from US-sourced forged or billet aluminum, assembled in Phoenix, Arizona
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Powder coated finish and dual seals against dust, weather and pressure
- 12 inch one-piece slotted, drilled and zinc plated vented rotor
- Park brake shoe assembly built into the backing plate, which also mounts the caliper
- Steel braided hoses, DOT approved
Before you buy
A rear disc upgrade changes how the axle handles braking loads, so the whole rear end should be inspected before the kit goes on. Wheel bearings, the axle seal and the brake lines all affect how the setup performs. Check that the axle shafts turn freely and that bearing play is within normal service specifications before mounting new hardware.
Park brake shoes sit inside the backing plate and usually wear more slowly than service brake pads, but they still need adjustment. If park brake cables are routed separately, make sure they clear the new caliper and hose path. Route the steel braided hose with slack through full suspension travel and away from the exhaust and driveline.
Pad wear and rotor condition are the main things to watch after installation. Look for scoring, heat blueing or thickness loss on the rotor, and bed in new pads gradually so the friction surface transfers evenly. Brake fluid absorbs moisture over time, so changing it at regular intervals helps keep the caliper pistons responding consistently.
- Inspect bearings and axle seals before mounting
- Check park brake cable routing
- Verify hose clearance at full suspension travel
- Bed in new pads gradually
- Replace brake fluid on a regular schedule
