Overview
The Baer Brakes 4262263MG is a rear brake system kit in Monster Green, pairing an S4 4-piston caliper with a 13 inch two-piece slotted, drilled rotor. It fits Ford 9 Inch Torino (Late Big) bearing housing ends with a 5×4.50/5×4.75 wheel bolt pattern.
The SS4 Plus design pairs a backing plate that carries the caliper with a one-piece park brake shoe assembly. Rotors arrive pre-assembled with NAS high grade stainless hardware, and braided hoses and hardware are included. The separate hat on the two-piece rotor is billet aluminum. The 13 inch rotor suits wheels 17 inch or larger, but fit to every wheel style is not guaranteed, so run a template check before mounting.

- Rotors pre-assembled with NAS high grade stainless hardware
- Braided hoses and hardware included
Matching wheels and axle
Rear brake upgrades on a Ford 9 inch axle start with the axle flange and bearing housing ends, since those decide whether the rotor and caliper bracket seat correctly. The wheel side matters just as much. A rotor with a larger outside diameter leaves less room behind the spokes, so a wheel with a deeper dish or a short backspacing can rub the caliper or the rotor hat. Placing the template against the wheel, with the tire already fitted, shows the clearance that matters.
Parking brake function depends on the shoe assembly inside the backing plate, so keep its adjustment and wear in mind during service. Two-piece rotors allow the hat and friction ring to be separated, which can simplify replacing a worn ring later. Check the friction surfaces for grooves, heat cracks and thickness below the minimum cast into the rotor. Brake pads, hoses and hardware are often renewed together, so a matched set keeps pedal feel consistent.
- Check wheel backspacing and clearance before buying
- Inspect the friction ring for cracks at each pad change
- Replace pads, hoses and hardware as a matched set when worn

Vehicle fitment
Fitment is set by the axle flange rather than by vehicle: Ford 9 Inch Torino (Late Big) bearing housing ends, a 5×4.50/5×4.75 bolt pattern and a 17.0 inch minimum wheel diameter. Confirm fit for your vehicle’s year, model and trim before ordering, and use the S135H template against your wheel.
Axle flange names do not establish a model or year range, so no vehicles are named here. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors come pre-assembled, which cuts down on bench work, but the park brake shoe sits inside the backing plate and park brake cables are not included. Lay the S135H template on your wheel before fitting. Have a qualified technician handle the rear brake installation, since a loose caliper bracket or a wrong pad can cause brake failure.
What’s included
Included: the S4 caliper in Monster Green, the backing plate with its one-piece park brake shoe assembly, the two-piece rotor with billet aluminum hat, and braided hoses and hardware.
Not included: park brake cables.
