Overview
The Baer Brakes 4302466S is a complete Pro Plus rear brake system for Detroit Speed (DSE) C6/DSE rear floater axles, supplied as a silver kit. It combines a two-piece, 6-piston Baer caliper with a 14 inch slotted, drilled, zinc-plated rotor, so the rear brake hardware arrives as one matched set rather than loose components.
Each hub ships pre-assembled with the bearings and races installed and packed with Redline synthetic grease. The kit is a general fit for GM C6/DSE floater rear ends and includes a Corvette Pb assembly. Wheel style clearance varies, so test template Q047P against the wheel you plan to use.
It suits owners of C6-style floater rear ends who want a larger, drilled rear brake with stainless steel pistons and a silver caliper finish.
Key features
- Two-piece, 6-piston, 6P caliper manufactured in Phoenix, AZ
- Caliper body CNC machined from forged or billet aluminum
- Silver powder-coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals protecting against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat
Choosing a rear brake upgrade
A rear disc upgrade on a floater axle changes more than stopping power. The larger rotor and caliper add weight to the unsprung corner of the vehicle, and the heavier hub assembly affects how the suspension responds over bumps. Drivers who run larger tires or frequent heavy towing usually benefit from matching front and rear brake balance, so the rear does not lock first under hard braking. Pad material should also suit how the vehicle is used, since aggressive compounds can wear rotors faster on daily driving.
Before purchase, measure the space between the wheel back face and the caliper area, and check that the wheel’s inner clearance matches the template check. Stainless pistons and dual seals help resist corrosion and debris, but seals still need periodic inspection for leaks. Plan for a brake fluid flush after the upgrade, because older fluid carries moisture that can soften pedal feel.
- Match pad compound to daily driving or towing
- Check wheel inner clearance against the caliper
- Inspect dust seals after off-road trips
- Flush brake fluid when upgrading components

Vehicle fitment
It is a general fit for GM C6/DSE floater rear ends. Confirm fit for your vehicle’s year, model and trim before ordering.
Wheel clearance is a separate check. The minimum wheel diameter is 18.0 Inch, and Baer recommends comparing template Q047P with the wheel of choice.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The hubs arrive with bearings and races already installed, so the main job is bolting the assembly to the control arms rather than repacking bearings. Because brakes are safety equipment, have a qualified technician install and test the system before the vehicle is driven.
What’s included
The kit ships as two boxes with the hubs pre-assembled and includes a Corvette Pb assembly as part of the system.
