Overview
The Baer Brakes 4262258GB is an SS4 Plus rear brake system kit finished in Grabber Blue, designed for Ford 8.8 Inch C-Clip rear ends with a 2.5 inch axle standoff. Its four-piston floating S4 caliper grips a 13 inch two-piece slotted, drilled and zinc plated rotor with a billet aluminum hat, and the listed minimum wheel size is 17.0 inch.
A single backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly, so the rear parking brake stays in the same unit. The rotor hardware arrives pre-assembled with NAS high grade stainless parts. The pad type is DR1-C, the rotor measures 0.81 thick, and the kit is made in the USA.
Key features
- Four-piston S4 caliper on a floating mount
- Two-piece slotted, drilled, zinc plated rotor with billet aluminum hat
- Hard anodized aluminum pistons with stainless steel abutments
- Noise suppression clips included
- Dual dust, weather and pressure seals
- Powder coated finish
- Stainless braided hoses and NAS stainless hardware included
Before you buy
A rear disc brake kit changes how the rear axle slows the vehicle, so it works best when the front brakes and overall brake balance are considered together. Floating calipers slide on their mounts as pads wear, which means the slide pins and pad surfaces should be kept clean and free of corrosion. Slotted and drilled rotors help shed heat and debris, but they tend to wear pads faster than plain rotors, so inspect the pads more often.
Before ordering, measure wheel backspacing and clearance against the caliper and rotor. Plan the parking brake cable route early, since cables come from a separate source. Brake hoses, wheel bearings and parking brake cables are often inspected or replaced during the same job, which keeps the rear end on a single service schedule.
- Check pad and rotor wear at each tire rotation
- Keep slide pins clean and lubricated with caliper grease
- Re-check lug nut torque after the first few drives
- Inspect braided hoses for cracking, chafing or leaks
- Bed in new pads gradually before heavy braking

Vehicle fitment
The rear axle flange is Ford 8.8 Inch, and the kit includes a 2.5 inch axle standoff. These measurements identify the axle assembly rather than a particular model year or trim.
Compare the S135H template with the wheel you plan to use. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Plan on wheels that are 17.0 inch or larger in diameter. Park brake cables are not part of the kit, although the park brake shoe assembly is, so cable routing should be settled before final assembly. A shop familiar with floating rear calipers and parking brake hardware is the right choice for this install.
What’s included
Included are the S4 caliper, the 13 inch two-piece rotor with billet aluminum hat, the backing plate and its park brake shoe assembly, stainless braided hoses, and NAS stainless hardware.
Not included: park brake cables.
