Overview
The Baer Brakes 4261654B is an S4 front disc brake kit for 1970–1974 Ford and Mercury models that originally came with drum brake spindles. It pairs a 4-piston S4TL top-loaded caliper with an 11 inch, 1-piece slotted, drilled, zinc-plated rotor sized for 15 inch wheels, giving classic muscle and compact cars a disc brake upgrade in a smaller package than Baer’s larger systems.
The kit fits the Ford Mustang, Fairlane, Falcon, Maverick and Torino and the Mercury Comet, Cougar, Cyclone and Montego, with model years shown in the Vehicle fitment section below.
Key features
- 4-piston S4TL caliper with a top-load design for quick, simple pad changes
- Dual dust, weather and pressure seals on the caliper
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Slotted, drilled and zinc-plated 1-piece vented rotor
- Billet aluminum hubs assembled with premium bearings packed with Redline synthetic grease
- Stainless steel braided brake hoses with DOT approval
- CNC machined aluminum components with a powder coated finish
Before you buy
A disc upgrade on a classic car is easiest to plan when the existing brake lines, pedal ratio and master cylinder are checked first. Many older cars were built with a single-circuit setup, so the new front components may need a matching master cylinder to keep the pedal feel consistent.
Because the rotor and hub are sold as part of a kit, it helps to confirm that the bearings, grease and dust caps are compatible with the rest of your front end. Plan on inspecting the pads and rotor surface after the first short break-in drives, since new friction material needs time to seat evenly.
- Check spindle type before ordering
- Inspect the master cylinder and lines
- Plan a break-in period for new pads

Installation notes
The kit is designed for vehicles with OE drum brake spindles, so check the spindle type before ordering. Baer recommends using the ST125A template to compare the 15 inch wheel of choice against the system before installation, because wheel clearance varies by wheel style and manufacturer. Brake work should be checked by a qualified technician.

The kit includes the 4-piston S4TL caliper, the 11 inch 1-piece slotted, drilled, zinc-plated rotor, billet aluminum hubs with premium bearings packed with Redline synthetic grease, billet aluminum dust caps, mounting brackets, stainless braided hoses and hardware.
