Overview
The Baer Brakes 4302471R is a rear Extreme Plus brake system in red for 1960-1988 Chevrolet and GMC C10 trucks with a 5 lug, 5×5.00 inch wheel pattern. It pairs a 1-piece Monoblock, 6-piston, 6S caliper with a 14 inch two-piece slotted, drilled, zinc-plated rotor. The backing plate serves as both the caliper mount and the housing for a 1-piece park brake shoe assembly.
The kit fits axles with 10 and 12 bolt C-clip housing ends. Rotors arrive pre-assembled with NAS high grade stainless hardware, and stainless braided hoses are included. The system uses the D1247 pad type and requires a minimum wheel diameter of 18.0 inch.
Key features
- 1-piece Monoblock, 6-piston, 6S caliper with a red powder coated finish
- CNC machined from US sourced 2618 aluminum forging
- Staggered pistons designed to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual dust, weather and pressure seals
- 2-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Floating caliper on a vented rotor, with the park brake shoe built into the backing plate
Choosing wheels and clearance
Rear brake kits like this one are judged first by wheel clearance. The caliper sits inside the wheel, so spoke design, offset and backspacing all affect whether the caliper and rotor sit without rubbing. Wheels that look similar can differ enough to change fit, which is why a template check before purchase matters on a truck that will carry a heavier load.
Once the wheels are confirmed, review the parking brake arrangement. A park shoe built into the backing plate works alongside the hydraulic system, so any tire size increase should be checked against caliper and backing plate clearance. Larger tires also change the leverage on the brake pads, so stopping distance and pad wear should be watched after the first few drives.
- Measure wheel backspacing before ordering
- Recheck clearance after any tire size change

Vehicle fitment
Fitment comes from the manufacturer list, which runs from 1960 to 1988 and names Chevrolet C10, R10 and Suburban models plus GMC 1000, C15, C1500, R1500 and Suburban trucks.
Coverage runs from 1960 to 1988 and includes Chevrolet C10, R10 and Suburban models plus GMC 1000, C15, C1500, R1500 and Suburban trucks. Full-size Chevrolet and GMC pickups outside this range are not covered, and this kit is for 2WD trucks only. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors come pre-assembled with stainless hardware, and the kit includes stainless braided hoses. Check that the axle housing ends match the 10 or 12 bolt C-clip pattern before starting. Baer recommends comparing wheel clearance with the N135P template, since the company cannot guarantee fit with every wheel style. Brake work is safety-critical, so have a qualified installer confirm clearance and hydraulics.
What’s included
The kit covers the 6S Monoblock caliper, the two-piece rotor with billet aluminum hat, the backing plate with park brake shoe assembly, stainless braided hoses, and pre-assembled stainless hardware.
Not included: the front rotor, lug nuts and park brake cables.
