Overview
Fire Red is the color of this Baer Brakes Extreme Plus rear brake kit, part number 4302471FR, built for 1960 to 1988 Chevrolet and GMC C10 trucks on 2WD chassis. It combines a one-piece six-piston 6S caliper with a 14 inch two-piece slotted, drilled and zinc plated rotor, suited to owners who want a matched rear system from one manufacturer.
The caliper body is CNC machined from 2618 aluminum and powder coated. Baer’s backing plate, which functions as the caliper mount, also houses a one-piece park brake shoe assembly. The rotors come pre-assembled with NAS high grade stainless hardware, and stainless braided hoses are supplied with the kit.
Key features
- Monoblock caliper with six pistons, manufactured in Phoenix, AZ
- CNC machined 2618 aluminum forging body
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to limit uneven pad wear
- Dual dust, weather and pressure seals
- Billet aluminum hat on the two-piece zinc plated rotor
- Park brake shoe assembly built into the backing plate
Why upgrade
Rear disc brakes are often chosen for steadier stopping and easier service than drum brakes. The rotor sheds heat faster and the pads are visible for inspection, so wear can be checked without taking the drum off. A matched caliper and rotor also keep the pedal feel consistent from one stop to the next.
Drivers who tow, carry extra weight or drive hills benefit most from a fully matched system. Brake hoses, fluid and the park brake all share the same job, so a single inspection should cover them together. Keep the caliper slides clean and lubricated, since seized slides are a common cause of uneven pad wear.
- Check rotor surface after heavy braking
- Lubricate caliper slide pins during pad service
- Replace hoses that show cracks or swelling
- Keep brake fluid fresh to resist moisture

Installation notes
The six-piston floating caliper sits on a 14 inch rotor, so wheel clearance must be checked first. Baer recommends comparing template N135P with the wheel you plan to use. The park brake shoes ride inside the backing plate, and park brake cables are not included, so plan to source them and test the park brake before normal road use.
What’s included
Supplied in the kit: the one-piece 6S monoblock caliper with six pistons, zinc plated two-piece rotors with billet aluminum hats, NAS stainless hardware for the rotors, the backing plate with a one-piece park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
