Overview
The Baer Brakes 4261640FR is a Pro front disc brake system in Fire Red, built for 1970–1973 Ford Mustang models and other listed 1970–1974 Ford and Mercury cars with factory drum brake spindles. Its six-piston caliper clamps a 13 inch vented rotor and takes the widely used D0731 pad.
Baer’s own note says the 13 inch Pro suits most wheels of 17 inch or larger. The rotor is one-piece with a slotted, drilled and zinc-plated surface, and the front hub carries a 5×4.50 bolt pattern with 1/2-20 x 2.25 inch studs, so measure your hub before you commit to a wheel.

- Forged or billet aluminum caliper body, CNC machined in the United States from sourced stock
- Stainless steel pistons, abutments and noise suppression clips

Installation notes
Check the spindle type first, because this system is designed around the factory drum spindle. Use the Q082H template against the wheel you plan to run, since Baer notes that wheel style and manufacturer can change clearance. Brake hoses must be bled after connection, and the car should be on stands during the work.
What’s included
Included are the six-piston Fire Red caliper, the 13 inch integral hub rotor with bearing races, premium bearings with Redline synthetic grease, new dust caps, all mounting brackets, stainless braided hoses and hardware.
