Overview
The Baer Brakes 4302469B is a black Extreme Plus rear brake kit for 1960-1986 Chevrolet C10 trucks with a 6-lug 2WD rear end and an OE C-clip axle. It uses a forged one-piece six-piston 6S caliper paired with a two-piece slotted and drilled rotor, and park brake parts come with it.
The Extreme Plus system is manufactured by Baer in Phoenix, Arizona, using US-sourced materials. Baer assembles the hubs before shipping, with bearings, races and Redline synthetic grease already in place, so you bolt the finished system onto the control arms. The title also names the Blazer and Suburban, so measure your housing against the template before buying.
Key features
- Forged one-piece monoblock six-piston 6S caliper
- Black powder-coated caliper finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered piston layout to minimize uneven pad wear
- Dual seals against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
Before you buy
The Extreme Plus system is a complete rear assembly, so it helps to think about the whole axle rather than only the caliper. C-clip axles hold each shaft with a clip at the inner end, and that design affects how bearings are removed and reinstalled during the swap. Checking the axle type at the start prevents surprises once the old drum parts are off.
Monoblock calipers hold their shape under heat and pressure, which supports a steady pedal feel under repeated braking. Pads wear over time and should be checked at regular service intervals. Rubber hoses and fluid also age, so inspecting them during the install is a practical step even with a new system.
- Confirm axle housing flange type before ordering
- Inspect axle bearings and seals while the hub is off
- Check parking brake adjustment after the first drive
- Keep the brake fluid fresh at each service
