Overview
The Baer Brakes 4262260GB is an SS4 Plus rear brake kit in Grabber Blue, matched to Ford 9 inch rear ends with early big bearing housing ends. It uses a four-piston S4 caliper and a 13 inch two-piece rotor that is slotted, drilled and zinc plated, and the kit targets 5 lug wheels on a 5×4.50/5×4.75 bolt pattern.
A backing plate doubles as the caliper mount and holds a modern one-piece park brake shoe assembly. Braided hoses and rotor hardware come with the kit. Per Baer, the 13 inch SS4 Plus is suited to wheels that are 17 inch or larger in diameter.
Key features
- Four-piston S4 caliper built with a two-piece body
- Machined from US sourced forged or billet aluminum in Phoenix, Arizona
- Grabber Blue powder coat finish
- Hard anodized pistons, stainless steel abutments and noise suppression clips
- Dual seals resist dust, weather and pressure
- Two-piece slotted, drilled and zinc plated rotor with billet aluminum hat
- Rotor hardware is NAS high grade stainless, supplied pre-assembled
Rotor care and inspection
A two-piece rotor is serviced differently from a one-piece unit. The friction ring and the hat are separate parts, so check the hat for looseness or cracks around the fasteners, and look at the ring for scoring, uneven wear and blueing from overheating. Inspect the rotor face each time the pads are changed, since small defects can be missed with the wheel on.
Off-road use puts extra heat and water into the brakes, so pads and rotors often wear faster than on pavement. Mud packed in the rotor slots can hold moisture, which may affect braking after a creek crossing. Rinse the assembly after heavy trail use, let it cool, and then look for leaks or grinding noises before the next drive.
- Check hat fasteners for looseness
- Look for scoring or blue discoloration on the friction ring
- Clear mud from the slots after trail use
- Inspect the park brake shoes when the rotor is off

Vehicle fitment
It mounts to the Ford 9 inch early big bearing axle flange, paired with 5 lug, 5×4.50/5×4.75 wheels. Your year, model and trim should be checked against the axle first.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Use the S135H template to compare the 13 inch rotor with the inside of your wheel; the listed minimum wheel diameter is 17.0 inch. Rotor thickness is 0.81, which matters when checking hub and caliper spacing.
