Overview
The Baer Brakes 4302577R is a Classic Series rear drum-to-disc brake conversion kit for 1988–1998 Chevrolet C1500 and GMC C1500 2WD trucks, and for 1992–1999 Suburban and Yukon SUVs, built for rear ends that use an OE C-clip. It replaces the factory rear drums with an 11.65 inch vented rotor, a red single-piston floating caliper with an integral park brake, and stainless braided brake hoses.
The Classic line is a full-feature conversion with modern components sized for smaller wheels. It fits some 15 inch wheels and most 16 inch or larger wheels, and the minimum wheel diameter is 15.0 inch. Wheel styles vary widely, so compare the template for this system against your wheel before mounting.

- Performance grade components for a 5 lug wheel with a 5×5.0/5.5 bolt pattern
- Supplied as a complete kit with brackets and mounting hardware
Before you mount the kit
Swapping drum rears for discs changes how the axle handles braking load, so the rest of the system matters. Front pads, rotors, the master cylinder and the brake fluid all work together with the new rear rotors. Many owners inspect the front brakes and replace the fluid during the same job, since a worn component elsewhere can show up as a soft pedal or uneven stops after the change.
Park brake cables need to be sourced separately and routed clear of the axle, driveshaft and exhaust. Set the cable length with the caliper lever in its released position, then test the park brake on a flat surface before relying on it. After the first few drives, recheck caliper bolts, hose fittings and lug nuts, and look for fluid at every connection.
- Inspect drum backing plates and axle hardware for wear before removal
- Bleed the hydraulic system fully after any hose is replaced
- Retest pedal firmness before the first highway trip
