Overview
The Baer Brakes 4302533R is a red SS4 Plus rear disc brake kit for Chevrolet and GMC C1500 2WD trucks from 1988 to 1998 and C1500 Suburban SUVs from 1992 to 1999. Its core is a 4-piston S4 caliper clamping a 13-inch 2-piece rotor, a combination meant for trucks fitted with the factory C-clip (Bih) rear end and 10-inch rear drums.
Baer built the backing plate to mount the caliper and to house a 1-piece park brake shoe assembly. Each rotor comes pre-assembled with NAS high grade stainless hardware. The S4 caliper is made in Phoenix, Az, from US sourced forged or billet aluminum.

- Noise suppression clips and dual seals against dust, weather and pressure
- Slotted, drilled, zinc-plate rotor with a billet aluminum hat
- Vented rotor construction in a 2-piece design
- Steel braided hose material, DOT approved
- DR1-C pad type, FMSI number DR1-C
- Park brake shoe assembly housed inside the backing plate
Choosing the right setup
A rear brake package works as one system with the front brakes, the master cylinder and the proportioning valve. A rear upgrade can shift how the truck slows, so a matched front system helps keep braking balance predictable. Pad compound should suit how the truck is driven, whether that means daily street use, towing or off-road trails.
Wheel choice is part of the decision too. A larger rotor needs room inside the wheel, and caliper clearance is a common issue. Track rotor runout and pad surfaces during each service, and replace parts that show heat cracks or deep grooves. The red finish is cosmetic and does not change how the brakes perform.
- Match pad compound to towing or trail use
- Check wheel clearance around the caliper
- Inspect rotors for heat cracks at every service

Vehicle fitment
It fits Chevrolet C1500 trucks from 1988-1998, Chevrolet C1500 Suburban SUVs from 1992-1999, the 1995-1999 Chevrolet Tahoe, GMC C1500 trucks from 1988-1998, GMC C1500 Suburban SUVs from 1992-1999 and the 1992-1999 GMC Yukon.
Fitment is for 2WD models only, so 4WD versions fall outside it. Vehicles with a different rear axle setup or drum size are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
A 13-inch rotor needs a wheel of at least 17.0 inch minimum diameter, so verify the wheel before mounting. Baer advises checking the S135H template against the chosen wheel, because it cannot promise clearance with every wheel style. Have the brake system bled and the park brake tested by a qualified technician once the kit is in place.
What’s included
The package holds the red S4 caliper, the pre-assembled 13-inch rotors with stainless hardware, the rear backing plate with its park brake shoe assembly, and stainless braided hoses with matching hardware.
