Overview
The Baer Brakes 4262259GB is a Grabber Blue SS4 rear disc brake kit for the Ford 9 inch early big bearing rear axle, with a 5×4.50/5×4.75 bolt pattern and five lugs. The kit centers on a four-piston S4 caliper clamping a 12-inch, one-piece slotted, drilled, zinc-plated rotor.
The backing plate mounts the caliper and carries a one-piece park brake shoe assembly. The pad type is DR1-C, the FMSI number, and braided hoses come with the kit. The minimum wheel diameter is 16.0 inch, so confirm wheel size before choosing this finish.
Key features
- Grabber Blue powder coated S4 caliper
- Four-piston design with hard anodized aluminum pistons
- Stainless steel abutments and noise suppression clips
- Dual dust, weather and pressure seals
- Vented one-piece rotor with zinc plate finish
- Park brake shoe assembly integrated into the backing plate
Parking brake and pad service
The parking brake on this kit runs through the backing plate, so the shoe assembly needs periodic attention even when the caliper is working well. Inspect the shoe lining, springs and adjuster during each rear service, and clean dust from the backing plate. When the parking brake is connected with cables, route them away from heat and check that they run freely.
Pads should match the FMSI number and be bedded in after installation. Light, progressive stops for the first few miles help lay an even layer of pad material on the rotor. Uneven pad wear, a soft pedal, or a parking brake that holds loosely are all reasons to pull the wheel and inspect before the next trip.
- Inspect shoe lining and springs each service
- Keep cable runs away from exhaust heat
- Match pad type to the FMSI number
- Check the rotor hat and hub face for corrosion

Vehicle fitment
It is built around the Ford 9 inch early big bearing axle flange, so check your rear axle and the S113E template against the application before buying.
The kit is not tied to any named model, so do not infer a fit from the axle name. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Use the S113E template to check clearance against your wheel, paying attention to the 16.0-inch minimum diameter. The parking brake cables are not supplied, so the park brake setup will need them from another source.
What’s included
The S4 caliper, the 12-inch one-piece rotor, the backing plate with its park brake shoe assembly, and stainless braided hoses.
Not included: Park brake cables.
