Overview
The Baer Brakes 4262654GB is an SS4 rear brake kit in Grabber Blue for Ford 8 Inch/9 Inch small bearing housing rear ends. It pairs a 12-inch vented rotor with a four-piston fixed S4 caliper, with a 5×5.00 inch bolt pattern and five lugs.
The backing plate mounts the caliper and houses a one-piece park brake shoe assembly, so one bracket handles both jobs. The 12-inch SS4 suits wheels 16 inch or larger, and the S4 caliper uses hard anodized aluminum pistons with stainless abutments.
Key features
- Four-piston S4 caliper of fixed design in Grabber Blue
- Hard anodized aluminum pistons paired with stainless steel abutments
- Seal pair handles dust and weather, plus pressure
- One-piece vented rotor, slotted, drilled and zinc plated
- Park brake shoe assembly housed in the backing plate
- Braided hoses, DOT approved and included
- Components manufactured in Phoenix, AZ from CNC-machined forged or billet aluminum
Caring for the caliper
A fixed four-piston caliper relies on clean pistons and seals to move freely. Dust and road grime collect around the piston boots, so a quick check during pad changes helps catch any seepage or corrosion before it reaches the bore. Anodized surfaces resist scratches but still need care when cleaning, since harsh abrasives can dull the finish.
Brake pads and rotors should be matched as a set. Mixing pad compounds can change friction and heat behavior, and a glazed pad can squeal or fade. When inspecting the caliper, look for fluid at the bleed screw, uneven pad wear that suggests a sticking piston, and cracked or missing noise clips.
- Clean around the piston area when pads change
- Look for fluid at the bleed screw and fittings
- Replace noise clips that are cracked or missing
