Overview
The Baer Brakes 4261654CY is a front S4 disc brake system with a Comp Yellow S4TL caliper, made for Ford and Mercury cars from 1970 to 1974 that run drum brake spindles. Its 11 inch 1-piece slotted, drilled and zinc-plated rotor takes the place of the drum set at the front, and the four-piston caliper clamps it.
Baer scaled the 11 inch SS4 from its larger designs so it suits 15 inch wheels. Billet aluminum hubs, mounting brackets, stainless braided hoses and hardware are all part of the package. The applications on the list are the Mustang, Fairlane, Falcon, Maverick, Torino, Comet, Cougar, Cyclone and Montego.
Key features
- Comp Yellow S4TL four-piston caliper with a top-load design
- 11 inch 1-piece vented rotor, slotted, drilled and zinc plated
- Hard anodized aluminum pistons and stainless steel abutments
- Dual seals for dust, weather and pressure
- Billet aluminum hubs with premium bearings
- Stainless braided steel hoses, brackets and hardware
- Performance grade with 5 lug, 5×4.50 pattern
Choosing the right setup
A drum-to-disc conversion changes more than the front stopping hardware. The master cylinder, proportioning valve and rear brakes all affect how the car balances braking, so review the whole system before committing to a front-only upgrade. Wheel offset and backspacing also determine whether the caliper clears the spokes or face of the wheel.
Comp Yellow calipers suit owners who want a visible color match with other parts, and the function is the same as the other finishes in this line. Pad compound is the choice that changes braking feel most, so select pads that suit the driving you do and the temperatures the brakes will see.
- Review master cylinder size before converting
- Confirm wheel backspacing against the caliper
- Choose pad compound for your typical driving

Installation notes
The kit is for original drum brake spindles, so verify that your car has them before starting. Check the wheel against the ST125A template first, since fit to every wheel style cannot be guaranteed. The caliper connects through the supplied stainless braided hoses and brackets. Braking components are safety-critical, so a qualified technician should handle the installation.
What’s included
The kit contains the Comp Yellow S4TL caliper, the 11 inch rotor, billet aluminum hubs with premium bearings and billet dust caps, mounting brackets, stainless braided hoses and hardware.
