Overview
The Baer Brakes 4262238GB is an SS4 rear brake kit for Ford 8 inch and 9 inch small bearing axle flanges, with a fixed 4-piston S4 caliper finished in Grabber Blue. It mounts to a 12 inch one-piece slotted, drilled, zinc-plated rotor and is made for the 5×4.50/5×4.75 bolt pattern.
A single backing plate carries the caliper and houses a one-piece park brake shoe assembly, so the parking brake sits within the rear unit. The S4 caliper runs hard anodized aluminum pistons with stainless steel abutments. The SS4 suits wheels of 16 inches and larger, and the S113E template is the tool Baer recommends for checking clearance. Components are CNC machined from US-sourced forged or billet aluminum at the Phoenix, AZ facility.
Key features
- Fixed four-piston S4 caliper with a powder-coated Grabber Blue finish.
- Hard anodized aluminum pistons for the S4 caliper.
- Dual seals for dust, weather and pressure.
- One-piece slotted, drilled, zinc-plated rotor.
- Stainless steel abutments and noise suppression clips.
- Stainless braided hoses, DOT approved.
Park brake maintenance
On a rear kit with an integrated park brake, the parking shoes sit inside the backing plate and generally wear more slowly than the service brakes during daily driving. They still need periodic checks, especially on vehicles parked on hills or driven in wet conditions where grit and water collect around the assembly.
Adjustment and cable tension matter as much as the shoes themselves. A slack cable can keep the lever from holding the vehicle, while a tight cable can drag the shoes after release. Inspect the cable routing, the lever and the shoe contact during routine service, and make sure the cable is protected from heat and road debris.
- Test the park brake on a slope before each season
- Look for rust on the cable sheath
- Keep the backing plate clear of mud and grease

Vehicle fitment
Match the Ford 8 inch or 9 inch small bearing axle flange and the 5×4.50/5×4.75 bolt pattern on your rear end before choosing this kit.
Rear ends with a different flange style fall outside the listed Ford 8 inch and 9 inch small bearing fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Park brake cables are not included, so the one-piece park brake shoe assembly will need a cable set sourced separately. Check that the 16 inch minimum wheel clears the S4 caliper using the S113E template. Have a qualified installer handle the brake work.
What’s included
The 12 inch rotor, the S4 caliper, the backing plate with one-piece park brake shoe assembly, and stainless braided hoses.
