Overview
The Baer Brakes 4261647R is a red S4 front integral hub disc kit for 1970 to 1974 Ford and Mercury cars equipped with drum spindles. Its 11.29 inch rotor is a 1-piece design with the hub built in, slotted, drilled and zinc plated, and a Red S4TL four-piston caliper grips it.
The S4 design comes from Baer’s larger systems, scaled down for 15 inch wheels with a minimum wheel diameter of 15.0 inch. The fitment covers Mustang, Maverick, Torino and Fairlane models, along with Mercury Comet, Cougar, Cyclone and Montego, each with drum spindles. Stainless braided hoses, brackets and hardware come with the kit.
Key features
- Red S4TL caliper with four pistons and a top-load design
- Integral hub rotor measuring 11.29 inch across
- Rotor surface slotted, drilled and zinc plated
- Dual dust, weather and pressure seals on the caliper
- Bearing races installed in the rotor from the factory
- New dust caps and premium bearings with Redline grease
- Template ST168B for checking wheel fit
Before you buy
A front integral hub disc conversion changes more than the brakes. The hub, bearings, spindle and wheel all work together, so check that the kit matches your spindle type before you order. Drum spindles and disc spindles are not interchangeable, and a kit built for one will not bolt correctly to the other.
Wheel clearance deserves the same attention. A larger rotor and a four-piston caliper can reduce clearance behind the spokes, so measure the wheel and template together. Brake hoses, pads and the master cylinder are often replaced alongside a conversion, since the old parts were sized for drum brakes and may not match the new hydraulic demand.
- Confirm the spindle type and bolt pattern match the vehicle
- Check wheel clearance against the caliper before mounting
- Inspect the master cylinder and proportioning valve during the swap
- Bleed the system completely after the hoses are fitted

Installation notes
This integral hub kit is made for drum brake spindles only, so confirm that before ordering. Compare the ST168B template with your wheel before mounting, since fit to every wheel style is not guaranteed. Brake work is safety-critical, so use an experienced installer.
