Overview
The Baer Brakes SS4 11.0-inch rear brake kit in Grabber Blue, part 4262773GB, is built around an S4TL four-piston caliper and an 11-inch one-piece rotor. It is sized for Ford 9 Inch Torino (late big) bearing housing ends and is sold as a complete kit.
The backing plate doubles as the caliper mount and holds a compact park brake assembly, a layout Baer describes as an aid to wheel fitment. Every listing detail points to 5 lugs on a 5×4.50/5×4.75 bolt pattern, so verify those numbers against your hub before ordering.

Before you buy
A rear disc conversion changes more than the brakes at the wheel. The backing plate, caliper and rotor all have to line up with the axle ends and the wheel, so measure your housing and hub before committing to a kit. Confirm the axle flange, lug count and bolt pattern on your vehicle, then compare them with the template and wheel clearance before ordering parts.
Because the park brake is part of the backing plate, the parking function depends on cable routing and adjustment as much as on the caliper itself. Plan the cable set, lines and mounting hardware together so nothing binds or rubs during the first install. Pads, hoses and fasteners are often replaced alongside a conversion, so budget for them now rather than after the first trail season.
- Measure axle flange and hub before ordering
- Plan park brake cables and routing in advance
- Budget for pads and fluid as part of the conversion

Vehicle fitment
It fits axle housings with the Ford 9 Inch Torino (late big) bearing axle flange. Confirm fit for your vehicle’s year, model and trim before ordering, and judge compatibility by the axle housing.
Baer cannot guarantee fit into every wheel style. Lay the ST217A template against your wheel before ordering.
Installation notes
The park brake cables are not part of this kit, so source a cable set that suits the park brake assembly housed in the backing plate. Stainless braided hoses and hardware are supplied. Test-fit the template and wheel before final assembly, and have a qualified brake shop handle the rear disc conversion because it affects the parking brake and hydraulic lines.
What’s included
The kit contains the S4TL caliper, 11-inch rotor, backing plate with park brake assembly, stainless braided hoses and hardware.
Not included: park brake cables.
