Overview
The Baer Brakes 4302533CY is a rear disc brake kit in Comp Yellow from the SS4 Plus line, pairing a 4-piston S4 caliper with a 13 inch two-piece slotted, drilled, zinc-plated rotor. It fits the rear axle of GM C1500 2WD trucks from 1988 to 1998, plus C1500 Suburban, Tahoe and Yukon models from 1992 to 1999.
Baer built the backing plate to carry the caliper and a one-piece park brake shoe assembly, so the parking brake comes as part of the kit. Rotors come assembled with NAS high grade stainless hardware, and Baer makes the calipers in Phoenix, AZ.
Key features
- Comp Yellow powder coated finish on the caliper
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Billet aluminum hat on the two-piece zinc-plated rotor
- Dual dust, weather and pressure seals
- Floating caliper with four pistons and a vented rotor
- Braided hoses with DOT approved rating
- Parking brake shoe assembly housed in the backing plate
- CNC machined from forged or billet aluminum
Choosing the right setup
A rear disc conversion is easiest to plan around the wheel first. Confirm that the wheel back spacing leaves room for the caliper body and that the tire sidewall clears the bracket at full steering lock. Also confirm that the axle and brake lines match the kit before any parts are unpacked.
Once the setup is settled, the parking brake needs its own check. Adjust the cable tension so the shoes engage properly, and test the park brake on a slope before driving. Pair the work with a fresh fluid change so the new caliper is not working with old fluid.
- Verify wheel back spacing against the caliper
- Set park brake cable tension after the first adjustment
- Replace aged rubber lines during the install

Vehicle fitment
Listed fitment covers 1988–1998 Chevrolet C1500 and GMC C1500, 1992–1999 Chevrolet C1500 Suburban and GMC C1500 Suburban, 1995–1999 Chevrolet Tahoe and 1992–1999 GMC Yukon. The kit’s notes say it is for trucks with the OE C-clip rear end and 10 inch rear drums.
Not covered: 2000-and-later models, Tahoe years before 1995, Yukon years before 1992, and 4WD versions, since this kit is built for 2WD trucks. Check the S135H template against any wheel you plan to run. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Stainless hardware and braided hoses come with the kit. Because the rotor is 13 inch, Baer calls for template checking against a wheel of 17 inch or larger. Rear brake work should go to someone familiar with disc brake systems.
What’s included
The Comp Yellow kit covers the S4 caliper, the two-piece slotted, drilled rotor with billet aluminum hat, the backing plate with park brake shoe assembly, the DR1-C pad type, and braided hoses with hardware.
