Overview
The Baer Brakes SS4 brake kit, part number 4262261GB, is a rear disc brake system with a 4-piston S4 caliper and a 12.0 Inch one-piece rotor that is slotted, drilled and zinc plated. The caliper is Grabber Blue, and the kit is made for Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern.
The park brake shoe assembly is part of Baer’s backing plate, which also serves as the caliper mount. The rotor’s 16.0 Inch minimum wheel diameter means it suits wheels 16 inches and up. Compare the S113E template against your wheel before mounting.
Key features
- Two-piece, 4-piston S4 caliper manufactured in Phoenix, Az
- CNC machined from US-sourced forged or billet aluminum
- Powder coated finish
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- One-piece slotted, drilled and zinc-plated rotor
Caliper seals and dust protection
The caliper’s dual seals keep dust, water and brake fluid pressure where they belong. Seals wear with heat cycles and age, so a seal that is dry, cracked or flattened can allow pistons to stick or fluid to seep past. Pistons that move unevenly often show uneven pad wear, which is an early sign to inspect the caliper.
Aluminum caliper bodies resist corrosion well when kept clean, but road salt, mud and trail grit can work into the piston bores and dust boots. Rinse the caliper after muddy outings and avoid high-pressure spray aimed at the seals. A light coat of suitable caliper grease on the slide pins helps them move freely.
- Look for fluid near the piston area
- Replace torn dust boots promptly
- Check slide pins for free movement

Vehicle fitment
Fit is set by the axle: Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern, and wheels of at least 16.0 Inch in diameter.
Grabber Blue is the caliper finish and does not affect fit. Check the axle flange and bolt pattern on your housing, and use the S113E template with your wheel. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
The backing plate, rotor and braided hoses are supplied with the kit. Park brake cables are not included and must be sourced separately. Use the S113E template to confirm wheel clearance, because the 16.0 Inch minimum is the figure to check against. Brake work should be done by a qualified technician.
What’s included
The package includes the S4 caliper, the one-piece rotor, Baer’s backing plate with park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
