Overview
The Baer Brakes 4262773MG is an SS4 rear brake kit in Monster Green, made for the Ford 9 inch rear end with Torino (late big) bearing housing ends. The package centers on an S4TL four-piston caliper clamping an 11-inch slotted, drilled rotor, and it includes a park brake assembly. Fitment is set by the axle flange and bolt pattern rather than by vehicle model.
Stainless steel braided hoses and hardware are also included, and the caliper has a banjo-type inlet. The brake hoses are DOT approved, and the pad type is FMSI 6070013. Baer’s backing plate mounts the caliper and holds the park brake assembly in a compact package.
Key features
- Monster Green powder-coated S4TL caliper
- Four-piston caliper with hard anodized aluminum pistons
- Backing plate serving as caliper mount and park brake housing
- Stainless steel abutments and noise suppression clips
- Dual dust/weather and pressure seals
- 11-inch one-piece slotted, drilled, zinc-plated rotor
- DOT approved steel braided hoses with banjo-type inlet
- Park brake assembly included
Setting up the park brake
The park brake is built into the backing plate, so setup involves more than bolting on a caliper. Cable length, routing and lever travel all affect how well the parking brake holds, and they should be checked with the wheel off before the first drive. Choose cable hardware that suits the axle housing and the lever geometry, since mismatched parts are a common cause of poor hold.
Monster Green is a finish choice that does not change how the system works, but the powder coat should be kept clean of road salt and grit to stay in good condition. Inspect the backing plate and mounting hardware periodically for loosening, and listen for rubbing from the rotor or dust shield after service. Pads and rotors wear at a similar pace on a rear system, so check them together.
- Verify lever travel before the first road test
- Keep the powder coat clean of road salt
- Recheck backing plate bolts after the first few drives

Vehicle fitment
Rear ends with other flange designs or bolt patterns are not covered by this kit. Check the year, model and trim of your vehicle before ordering.
Rear ends with other flange designs or bolt patterns are not covered by this kit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check wheel clearance with Baer template ST217A, using the 15.0-inch minimum wheel diameter as the reference point. Park brake cables are not included, so they must be supplied separately for the park brake to function. A qualified installer should set up and bleed the system, since brake performance depends on that work.

The kit includes the Monster Green S4TL caliper, the 11-inch slotted, drilled, zinc-plated rotor, the backing plate with park brake assembly, steel braided hoses and hardware.
Not included: Park brake cables.
