Overview
The Baer Brakes SS4 front brake system, part number 4261654MG, pairs a Monster Green S4TL 4-piston caliper with an 11 inch one-piece rotor. It fits Ford and Mercury cars from 1970 to 1974 that use drum brake spindles at the front, such as the Mustang, Maverick, Torino and Cougar.
Baer built the SS4 as a smaller version of its larger brake systems, for wheels 15 inch and up. Billet aluminum hubs, bearings, brackets, braided hoses and hardware come together as one kit, so the front end is covered in a single package.
Key features
- Monster Green powder coated caliper, 4-piston, top loaded and fixed
- 11 inch vented rotor in one piece, slotted, drilled and zinc plated
- Pistons are hard anodized aluminum; abutments are stainless steel, and noise suppression clips are included
- Dual dust, weather and pressure seals, with a top load design that supports quick pad changes
- Billet aluminum hubs assembled with premium bearings packed in Redline synthetic grease
- Stainless steel braided hoses, DOT approved, with mounting brackets and hardware
- Components CNC machined from US sourced forged or billet aluminum in Phoenix, Arizona
Hub and bearing service
Hubs that arrive with bearings already assembled still need periodic service. Grease packed at assembly lasts well, but heat and water can break it down over time. Inspect the hub seal, dust cap and bearing play whenever the wheel is removed, and replace the grease if it looks dry or contaminated.
Bearing preload matters on a disc setup. Follow the correct torque sequence on the spindle nut and recheck the wheel for play after a short drive. Pair the new front hubs with a wheel that clears the caliper and rotor fully, and keep the lug studs clean and free of rust so the wheels seat flat.
- Inspect dust caps and seals at each wheel service
- Check bearing play after the first short drive
- Keep lug studs clean before mounting wheels

Vehicle fitment
The manufacturer list for this green kit names the 1970 Ford Fairlane and Falcon, 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, 1970 Mercury Cyclone and 1970 to 1971 Mercury Montego, each with drum brake spindles at the front.
Vehicles from other years or models, such as a 1969 Mustang or a 1975 Maverick, are not covered, and disc spindle applications are not on the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Each hub comes assembled with bearings, so the bearing set is part of the hub assembly. Check the wheels against the ST125A template before fitting, because the minimum wheel diameter is 15.0 inch.
A qualified installer should confirm the braided hose routing and pad clearance, then test the brake pedal before the car is driven.
What’s included
The kit covers the Monster Green S4TL caliper, 11 inch rotor, billet aluminum hubs with bearings and dust caps, mounting brackets, stainless steel braided hoses and hardware.
Not included: Wheels, which need to meet the 15.0 inch minimum diameter.
