Overview
The Baer Brakes Extreme Plus 4302472B is a complete rear brake kit with a 15 inch two-piece slotted and drilled rotor and a 6-piston 6S caliper, fitting 1960-1986 Chevrolet C10 trucks. The kit is set up for a 2WD rear end with a 5-lug wheel pattern and a C-clip axle.
The hubs are assembled before shipping, with bearings and races installed and packed with Redline synthetic grease, so the hub assembly is ready to mount. Not every wheel style will clear, so check clearance with template N135U against the wheel you plan to use before ordering.
Key features
- Forged one-piece monoblock 6-piston 6S caliper with a black powder coated finish
- Caliper made in Phoenix, Arizona from US-sourced materials
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled and zinc-plated rotor with a billet aluminum hat
- Hubs packed with Redline synthetic grease before shipping
Choosing a rear brake upgrade
Upgrading a rear disc system affects the whole axle, so it helps to look at the parts that wear with it. The rotor, pads, hubs and park brake shoe usually wear at different rates, and replacing them together keeps the system balanced. Note the rotor thickness and the condition of the hub bearings before deciding which parts to replace.
A larger rotor and a multi-piston caliper change how heat and pad pressure are shared across the axle. Brake fluid and lines should be checked when a bigger system is installed, because the caliper may draw more fluid. Care for the system by checking the pads for uneven wear and the hub bearings for play after the first several drives.
- Check rotor thickness before fitting
- Replace park brake shoes with the kit if worn
- Inspect brake lines for flex or leaks
