Overview
Black is the caliper finish on the Baer 4302533B, an SS4 Plus rear kit with a four-piston S4 caliper and a 13 inch two-piece rotor. It covers 1988–1998 Chevrolet and GMC C1500 2WD trucks, plus 1992–1999 C1500 Suburbans and the 1995–1999 Tahoe and 1992–1999 Yukon SUVs listed in the fitment section below.
The backing plate doubles as the caliper mount and holds a modern one-piece park brake shoe. Pre-assembled rotors use NAS high grade stainless fasteners, and the caliper relies on hard anodized aluminum pistons for consistent sealing.
Key features
- Black powder coated S4 caliper body
- Four floating pistons with dual weather and pressure seals
- Slotted, drilled and zinc-plated two-piece rotor
- Billet aluminum rotor hat
- CNC machined forged or billet aluminum components
- Stainless steel abutments and noise suppression clips
- Park brake shoe built into the backing plate
- Braided brake hoses with DOT approval
Things to check
Black calipers show dust and pad residue more than lighter finishes, so a quick wipe during tire rotation makes wear easier to spot. Check the caliper body for chips in the powder coat, since bare metal can start corrosion along the edges. Slide pins should be cleaned and lubricated with a high temperature brake lubricant during pad changes.
Rear discs work alongside the parking brake shoe in the backing plate, so the park brake should be tested after any pad or rotor service. Listen for scraping during the first stops and check that the rotor surface is not glazed or scored. Pulsing through the pedal usually points to rotor runout or uneven pad transfer.
- Clean slide pins during pad changes
- Look for chips in the caliper finish
- Test the park brake after every service

Vehicle fitment
Fitment covers 1988–1998 Chevrolet C1500 and GMC C1500 trucks, 1992–1999 Chevrolet and GMC C1500 Suburbans, 1995–1999 Chevrolet Tahoe, and 1992–1999 GMC Yukon. The kit requires the OE C-clip rear end with 10 inch rear drums.
Not listed: Tahoe models before 1995, Yukon models before 1992, 4WD vehicles, and model years after 1999 for these nameplates. Baer cannot promise fit into every wheel style, so use the S135H template. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Pre-assembled rotors and braided hoses come with the kit, and the park brake shoe assembly sits inside the backing plate. Compare the 13 inch rotor with the S135H template before mounting on wheels of 17 inch or larger. Rear disc work is best left to a shop that handles brake installs.
What’s included
The kit includes the black S4 caliper, two-piece zinc-plated rotor, backing plate with park brake shoe assembly, DR1-C pad type, and braided hoses with hardware.
Not included: Park brake cables.
