Overview
The Baer Brakes Track4 front brake system, part number 4261291MG, is a front disc upgrade for 1970 to 1974 Ford and Mercury cars that originally used drum brake spindles. It pairs a Monster Green T4 four-piston caliper with a 13 inch one-piece slotted, drilled and zinc plated rotor. The listed applications are the Ford Falcon, Fairlane, Maverick, Mustang and Torino and the Mercury Comet, Cougar, Cyclone and Montego.
The Track4 is built for owners who want front disc stopping without changing away from the spindle type the car already uses. Baer manufactures the T4 caliper in Phoenix, Arizona, and CNC machines it from US sourced forged or billet aluminum. The Monster Green powder coat suits restored and show cars that need a color-matched front brake setup.

Choosing the right setup
Converting a drum spindle car to disc is mostly a matter of matching the spindle, hub and wheel before any hardware goes on. Measure the wheel you plan to run and confirm it clears the caliper and rotor, since larger brake packages often change the clearance a wheel needs. Keep the front steering and suspension in mind as well, because a heavier brake assembly adds load to the spindle and the parts around it.
Front disc upgrades are often paired with a brake fluid change and a check of the pedal feel so the new caliper responds firmly. Many owners also replace the wheel bearings and flexible lines while the hubs are apart, since that work is already done with the assembly off the car.
- Confirm the spindle type before ordering parts
- Check wheel clearance around the caliper and rotor
- Inspect older brake lines and replace any that are cracked
- Match pad material to how the car will be driven

Cars with factory disc spindles are not covered, and model years outside the listed ranges, such as 1969 or 1975 models, are not in the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The kit is designed around the OE drum brake spindle, so check that the spindles on your car are drum type before fitting. Baer recommends comparing its template Q082H with the wheel you intend to run, because the company cannot guarantee fit to every wheel style and the kit is designed for 17 inch or larger wheels.
Brake work directly affects stopping distance, so have a qualified shop install and bleed the system if you are not experienced with disc brake conversions.
What’s included
The kit includes the T4 caliper and 13 inch rotor system for the front axle, billet aluminum hubs with premium bearings packed with Redline synthetic grease, billet dust caps, all mounting brackets, stainless braided hoses and hardware.
