Overview
The Baer Brakes SS4 rear brake system, part number 4262236CY, is a 12.0 inch disc brake kit built around an S4 4-piston caliper in Comp Yellow. It is designed for Ford 9 Inch Torino (Late Big) bearing housing ends with a 5×4.50/5×4.75 bolt pattern and suits 5-lug rear axles.
The backing plate carries the caliper and also houses a modern 1-piece park brake shoe assembly. Braided hoses come with the kit. No vehicle year or model is named for it, so match the axle flange and bolt pattern to your rear end before choosing this system.
Key features
- S4 4-piston caliper with a fixed design, CNC machined from US-sourced forged or billet aluminum.
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips.

- Powder-coated caliper finish in Comp Yellow.
- 1-piece slotted, drilled, zinc-plated 12 inch vented rotor.
- Backing plate houses a 1-piece park brake shoe assembly.
- Brake hose is DOT approved, and braided hoses are included.
- Designed for most 16 inch or larger wheels.
Before you commit to rear discs
Swapping a rear drum setup for discs changes how the parking brake works, so the park brake shoe assembly and its cables are part of the decision. Cables that have stretched, corroded or seized will not hold the shoes properly, and a loose cable set can make the parking brake feel weak even when the hydraulics are sound.
On the trail, rear brakes see heavy use on steep descents and in mud, where caked dirt can wear pads faster than road driving. Keep an eye on pad thickness and rotor surface, and check the caliper slide area for dirt or corrosion at each service. Inspect hoses for chafing and swelling, and bleed the system after any hose or caliper work to keep the pedal firm.
- Check park brake cable routing and free movement before final assembly
- Inspect pads and rotor face for scoring or heat marks
- Look for seepage at hose fittings after the first few drives
- Replace the rotor and pads as a matched set when either is worn

Vehicle fitment
The kit suits Ford 9 Inch Torino (Late Big) bearing housing ends on a 5×4.50/5×4.75 bolt pattern. Compare that axle flange with your rear axle before choosing this system.
Fit is limited to the Ford 9 Inch Torino (Late Big) bearing flange, and Ford 9 inch axles with a different bearing flange are not a match for this kit. Verify the year, model and trim of your vehicle before placing the order.
Installation notes
Park brake cables are not included, so the park brake shoe assembly needs cables sourced separately. Baer recommends using the S113E template to compare the kit with your chosen wheel, since Baer cannot guarantee fit to every wheel style. A qualified technician should fit this rear brake system.

The kit includes the S4 4-piston caliper in Comp Yellow, the 12.0 inch 1-piece slotted, drilled rotor, the backing plate with its 1-piece park brake shoe assembly, and braided hoses.
