Overview
The Baer Brakes 4302533GB is a Grabber Blue SS4 Plus rear brake system for the 1988-1998 GM C1500 2WD trucks and the 1992-1999 C1500 Suburban SUVs. A 4-piston S4 caliper works with a 13-inch 2-piece slotted, drilled rotor, and the design suits trucks that have the OE C-clip (Bih) rear end and 10-inch rear drums.
The backing plate supports the caliper and houses a modern 1-piece park brake shoe assembly, so the parking brake is part of the same rear package. Rotors come pre-assembled with stainless hardware, and stainless braided hoses are included. The S4 caliper is manufactured in Phoenix, Az.

Care and inspection
Brake pads are the part most owners replace first, and they wear faster with heavy use. Check thickness at every service and look for uneven wear between the inboard and outboard pads. Scoring or a blue tint on the rotor surface can signal overheating, so have it inspected before it gets worse.
Clean the caliper and backing plate after exposure to salt or mud. Dust boots and seals keep moisture out of the piston bores, and a damaged seal can cause a sticking caliper. Brake fluid absorbs water over time, so replacing it on a regular schedule protects the system. Lubricate the slide hardware whenever the pads are changed.
- Check pad thickness at every service
- Look for scoring or blue discoloration on rotors
- Replace brake fluid on a regular schedule

Vehicle fitment
Vehicles covered include the 1988-1998 Chevrolet C1500 pickups, 1992-1999 Chevrolet C1500 Suburban, 1995-1999 Chevrolet Tahoe, 1988-1998 GMC C1500 pickups, 1992-1999 GMC C1500 Suburban and 1992-1999 GMC Yukon.
Only 2WD applications are listed, so 4WD trucks fall outside the fitment. Rear ends that lack the OE C-clip (Bih) or that use other drum sizes are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Compare the S135H template with the wheel you intend to run before mounting, since Baer cannot promise fit across every wheel design. The kit’s minimum wheel diameter is 17.0 inch. Have a qualified technician bleed the brake lines and check park brake operation after installation, because brake work is safety-critical.
