Overview
The Baer Brakes 4302481R is a red Extreme Plus rear brake system kit built for the Detroit Speed (DSE) C6/DSE rear floater axle. It packages a forged one-piece 6S six-piston caliper, a 14 inch rotor and a prepared hub, so a rear brake upgrade arrives as one assembly.
Baer installs the bearings and races in each hub before shipment and packs them with Redline synthetic grease. The kit is a general fit for GM C6/DSE floater setups that use the Corvette Pb assembly. Confirm fit for your vehicle’s year, model and trim before ordering.
Key features
- Forged one-piece monoblock caliper with six pistons, designated 6S
- Powder coated red finish on the caliper body
- Stainless steel pistons, abutments and noise suppression clips
- Staggered piston arrangement intended to reduce uneven pad wear
- Dual seals rated against dust, weather and pressure
- Drilled, slotted, zinc-plated two-piece rotor with billet aluminum hat
- Manufactured in Phoenix, Az from US-sourced materials
Caring for a floater rear brake
A rear disc upgrade changes how the axle carries braking load, so it helps to treat the hub, bearings, rotor and caliper as one system. On a floater axle the hub assembly carries the wheel and the brake forces pass through the control arm mounts. The hubs arrive with bearings and races already in place, so installation centers on bolting the assembly to the arms and connecting the brake hardware correctly.
Pads wear at different rates depending on driving, so inspect them at each tire rotation and replace them before the friction material gets thin. Look at the rotor for deep scoring, heat checking or cracks, and keep the caliper slides and seals clean. Brake fluid absorbs moisture over time, so a regular fluid change keeps pedal feel consistent.
- Recheck lug nut torque after the first few drives
- Bed in new pads with a gradual series of stops
- Inspect brake lines for chafing near the control arms
- Keep the parking brake adjusted after installation

Vehicle fitment
It is a general fit for the GM C6/DSE floater with the Corvette Pb assembly. Confirm fit for your axle before ordering.
Other GM rear axles and floater setups fall outside this kit’s design. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Bearings and races are already installed and packed in the hubs, so the remaining work is bolting the assembly to the control arms. Compare the 6S caliper and 14 inch rotor against your wheel before mounting.
What’s included
The kit includes the red 6S rear caliper, the 14 inch two-piece rotor with billet aluminum hat, the prepared hub assembly with bearings and races, and the Corvette Pb assembly.
Not included: Wheels are not part of the package; choose a wheel with a minimum diameter of 18.0 inch.
