Overview
The Baer Brakes 4302533FR is a rear disc brake kit in Fire Red, built on the SS4 Plus system with a 4-piston S4 caliper and a 13 inch two-piece slotted, drilled, zinc-plated rotor. It is made for GM C1500 2WD trucks and SUVs from 1988 to 1999 that have the OE C-clip rear end and 10 inch rear drums.
Baer’s backing plate serves as the caliper mount and also houses a one-piece park brake shoe assembly, so the parking brake is built into the same kit. The rotors arrive pre-assembled with NAS high grade stainless hardware, and the caliper carries a powder coated Fire Red finish.
Key features
- 4-piston S4 caliper with hard anodized aluminum pistons and stainless steel abutments
- Two-piece rotor with slotted, drilled and zinc-plated surface and billet aluminum hat
- Dual seals for dust, weather and pressure on the caliper
- CNC machined from forged or billet aluminum with a powder coated finish
- Stainless steel noise suppression clips
- Braided brake hoses with DOT approved rating
- Park brake shoe assembly built into the backing plate
- Floating caliper design with a vented rotor
Before you buy
Converting rear drums to discs changes how the parking brake and hydraulic system work together, so plan the job as a full system rather than a single part swap. Check the rear axle, hub and brake line routing before ordering, and make sure the master cylinder and proportioning setup suit the added caliper load.
Pads and rotors are usually replaced as a set, and a fresh rotor should be inspected for runout and a clean surface before the caliper goes on. Once installed, bed in the pads with a series of moderate stops, then recheck torque on the caliper bracket and wheel hardware after the first few drives.
- Use fresh brake fluid matched to the system
- Inspect braided hoses for chafing at each service
- Keep park brake cable routing clear of the exhaust

Vehicle fitment
It fits 1988–1998 Chevrolet C1500 and GMC C1500 trucks, 1992–1999 Chevrolet C1500 Suburban and GMC C1500 Suburban, 1995–1999 Chevrolet Tahoe, and 1992–1999 GMC Yukon. Fitment requires the OE C-clip rear end and 10 inch rear drums.
Tahoe years before 1995, Yukon years before 1992, 4WD models and anything after 1999 are not on the list. Baer also cannot guarantee fit into every wheel style, so check the S135H template against your wheel. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors come pre-assembled, and braided hoses and hardware are included with the kit. Use the S135H template to confirm that the 13 inch rotor clears a wheel of 17 inch or larger before mounting. Work on rear brakes should be done by someone experienced with disc brake systems.
What’s included
The kit includes the S4 caliper, the 13 inch two-piece rotor with billet aluminum hat, the backing plate with its park brake shoe assembly, the DR1-C pad type, and braided hoses with hardware.
Not included: Park brake cables.
