Overview
The Baer Brakes S4 front brake system in red, part number 4261654R, includes a red 4-piston S4TL caliper and an 11 inch vented rotor. It fits 1970 to 1974 Ford and Mercury models with drum brake spindles at the front, including the Ford Torino, Mercury Montego and Mercury Comet.
The S4 is a smaller version of Baer’s larger brake systems, built for wheels 15 inch and up. Its parts are CNC machined from US sourced forged or billet aluminum and made in Phoenix, Arizona.

- Steel braided hoses with DOT approval, plus mounting brackets and hardware included in the kit
- CNC machined components of US sourced forged or billet aluminum, made in Phoenix, Arizona
Setting up the red kit
A red powder coated caliper holds its color well under normal brake heat, but it should be kept free of harsh solvents during cleaning. Wipe the caliper with mild soap and water, and avoid spraying brake cleaner directly onto the finish. Check the caliper slide surfaces for corrosion each time the pads are changed, since clean slides keep the pads moving evenly.
Because the hoses are braided steel, route them away from the exhaust and check the fittings after the first few drives. Bleed the system in the correct order and use fresh fluid. Front brake work often reveals worn wheel bearings or ball joints, so inspect those parts while the wheels are off.
- Clean the caliper with mild soap and water
- Inspect slide pins and boots at each pad change
- Re-check hose fittings after the first drives

Vehicle fitment
Fitment comes from the manufacturer list, which places this red kit on the 1970 Ford Fairlane and Falcon, 1970 Mercury Cyclone, 1970 to 1974 Ford Maverick, 1970 to 1973 Ford Mustang, 1970 to 1971 Ford Torino, 1971 to 1974 Mercury Comet, 1970 to 1973 Mercury Cougar and 1970 to 1971 Mercury Montego, all fitted with OE drum brake spindles.
Years and models outside the listed ranges, including 1969 Mustangs and 1975 Mavericks, are not covered. The kit requires OE drum brake spindles at the front. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The hubs come assembled with premium bearings and billet dust caps. Test-fit each wheel against the ST125A template first, since the minimum wheel diameter is 15.0 inch and Baer cannot promise clearance with every wheel style.
A qualified technician should install the brakes, confirm every hose connection, and test the pedal before the vehicle is driven.
What’s included
The kit contains the red S4TL caliper, the 11 inch rotor, billet aluminum hubs assembled with bearings, mounting brackets, stainless steel braided hoses and hardware.
Not included: Wheels and tires, which must meet the 15.0 inch minimum wheel diameter.
