Overview
The Baer SS4 Plus front brake kit in Grabber Blue, part number 4261379GB, is an 11-inch four-piston disc brake system for Ford and Mercury cars from 1970 to 1974 that have drum brake spindles at the front. Its S4 caliper clamps a two-piece slotted, drilled and zinc-plated rotor, and the kit is built for 15-inch wheels and larger.
Baer presents the SS4 Plus as its larger systems in a smaller package. The hubs are billet aluminum with premium bearings, and the rotors come pre-assembled with stainless hardware. Mounting brackets, stainless braided hoses and hardware are all included, so the kit arrives as one matched set.
Key features
- Grabber Blue powder-coated S4 caliper with four pistons
- Two-piece rotor, 11.0 inches, with a slotted and drilled zinc-plated face
- Hard anodized pistons with stainless steel abutments
- Dual seal design rated for dust, weather and pressure
- Billet aluminum hubs with synthetic grease packed bearings
- Made in Phoenix, Arizona, using US-sourced forged or billet aluminum
Things to check before fitting
The first check is the spindle. Disc conversions of this type are built around original drum brake spindles, so inspect the spindle for wear, cracks or machining changes before assuming the kit will bolt on. Wheel bearings, grease seals and steering components should be in good shape, since the front end will carry the new brake hardware and the loads that come with it.
Wheel clearance deserves a careful look too. Compare the wheel with the template and check that the wheel’s backspacing and center bore suit the hub and caliper. Some wheel styles clear the caliper only with a specific offset, so test fit before final tightening.
Once the brakes are installed, the most common issues are leaks at fittings and pedal feel that changes as the pads seat. Recheck the fluid level, inspect the hoses for rubbing, and retighten the lug nuts after the first short drives. Replace worn pads and rotors together to keep braking even.

Vehicle fitment
The following applications all require cars with drum brake spindles:
- 1970 Ford Fairlane
- 1970 Ford Falcon
- 1970–1974 Ford Maverick
- 1970–1973 Ford Mustang
- 1970–1971 Ford Torino
- 1971–1974 Mercury Comet
- 1970–1973 Mercury Cougar
- 1970 Mercury Cyclone
- 1970–1971 Mercury Montego
The list ends at 1971 for the Torino and Montego, and at 1970 for the Fairlane, Falcon and Cyclone. Later years, such as Mustang models from 1975, sit outside it. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The SS4 Plus requires OE drum brake spindles, so confirm that spindle type on your car before fitting. Compare the wheel with the S162A template before ordering, since wheel fit can vary by style. Brake work is safety-critical, so have the new lines bled and the pads bedded by someone experienced with disc brakes.
What’s included
Mounting brackets, braided hoses and the included hardware. Billet aluminum hubs with bearings and dust caps. Rotors pre-assembled with stainless hardware. Four-piston S4 caliper.
