Overview
The Baer Brakes 4262255HO is a rear SS4 Plus brake system with a 13 inch two-piece rotor, sized for Ford axles that use the 8 inch or 9 inch small bearing axle flange. A fixed S4 four-piston caliper finished in Hugger Orange clamps the rotor, and the kit is set up for five-lug wheels on a 5×4.50/5×4.75 bolt circle.
Baer’s SS4 Plus design pairs a backing plate, which works as the caliper mount, with a one-piece park brake shoe assembly. Pre-assembled rotors come with NAS high grade stainless hardware. Confirm the axle flange and bolt pattern first, since they decide whether the kit suits your axle.
Key features
- Fixed four-piston S4 caliper in Hugger Orange powder coat
- Stainless steel abutments and noise clips sit alongside hard anodized pistons
- Dual dust, weather and pressure seals
- Slotted, drilled and zinc plated two-piece rotor on a billet aluminum hat
- Park brake shoe assembly built into the backing plate
- Steel braided, DOT approved brake hoses
- Caliper body cut from billet or forged US aluminum
Pads and rotor wear
A fixed four-piston caliper applies even pressure across the pad, which helps the pad wear evenly over its life. Pads should be checked for thickness and for glazing, since a glazed surface reduces bite and can cause noise. Rotors on a two-piece design can be pulled and inspected separately from the hat, which makes measuring the braking surface straightforward at each service.
Good bedding of new pads matters more than many owners expect. Use a series of moderate stops to build an even layer of friction material before any hard braking. Keep the rotor surface clean of grease, and replace any pad that has been contaminated. Grooves and deep heat marks on the rotor are reasons to resurface or replace it before it reaches its limit.
- Check pad thickness at each service
- Inspect rotor hat fasteners after the first drives
- Clean the rotor face before reinstalling pads

Vehicle fitment
The kit is designed for Ford rear axles with an 8 inch or 9 inch small bearing flange and five-lug, 5×4.50/5×4.75 hubs.
Wheel designs differ widely, so test the S135H template against the wheel before committing. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
Mounting the park brake shoe assembly happens through the backing plate, which doubles as the caliper bracket, so the parking brake is set up during the same fit. Park brake cables are not part of this kit. Use the template to confirm your wheels clear the 17.0 inch minimum diameter. Mounting with care under a professional installer is the safer route.
What’s included
Supplied in the kit: a Hugger Orange S4 caliper, the two-piece 13.0 inch rotor with billet hat, the backing plate with park brake shoes, and stainless braided hoses with hardware.
