Overview
The Baer Brakes 4261647GB is a front S4 brake system with a Grabber Blue caliper, aimed at 1970 to 1974 Ford and Mercury models that originally used drum brakes up front. It combines a 4-piston S4TL caliper with an 11.29 inch vented rotor.
The SS4 design is a scaled-down version of Baer’s larger brake systems, fitted here to 15 inch wheels. Applications include the Ford Mustang, Fairlane, Falcon, Maverick and Torino and the Mercury Comet, Cougar, Cyclone and Montego, detailed under vehicle fitment below. Grabber Blue is the caliper color named by Baer.
Key features
- S4TL four-piston caliper with top loading for simpler pad changes
- Aluminum pistons hard anodized, paired with stainless steel abutments and noise suppression clips
- Dust, weather and pressure sealed by dual seals
- Caliper powder coated and machined from forged or billet US-sourced aluminum
- Integral hub rotor is 1-piece, slotted, drilled and zinc-plated
- Rotors come with bearing races and premium bearings, greased with Redline synthetic, plus new dust caps
- Brackets, braided hoses and hardware included with the system
Checking spindles and clearance
Spindle type decides whether a disc conversion is practical. A drum-equipped front end has a backing plate and drum assembly around the hub, while a disc setup mounts a caliper bracket to the spindle. Look over the hub, spindle and dust shield before ordering so you know what is already on the car.
The hub bearings are opened during a rotor install, so their condition is worth checking at the same time. Look for roughness, play and dry or discolored grease. Clean the spindle and mating surfaces before the new rotor goes on, since rust or debris can throw off how the rotor seats.
Wheel clearance is the last check. Measure the space between the wheel’s inner barrel and the caliper body before ordering wheels, and remember that tire size can change clearance as well.
- Spindle identified as drum-type before ordering
- Hub bearings inspected and repacked or replaced as needed
- Mating surfaces cleaned and free of rust
- Wheel and tire clearance measured against the caliper

Vehicle fitment
It fits these OE drum brake spindle applications: 1970 Ford Fairlane, 1970 Ford Falcon, 1970 through 1974 Ford Maverick, 1970 through 1973 Ford Mustang, 1970 through 1971 Ford Torino, 1971 through 1974 Mercury Comet, 1970 through 1973 Mercury Cougar, 1970 Mercury Cyclone and 1970 through 1971 Mercury Montego.
Years beyond those ranges, such as a 1974 Mustang or a 1972 Montego, fall outside the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Start by confirming the car uses OE drum brake spindles, because this system is listed only for that setup. Use Baer’s ST168B template to check wheel clearance before choosing wheels. A qualified technician should handle the installation of front brake hardware.
What’s included
The package covers the Grabber Blue S4TL caliper, the 11.29 inch 1-piece integral hub rotor with bearing races and premium bearings, brackets, braided hoses, dust caps and hardware.
