Overview
Grabber Blue is the finish on this Baer Brakes 4302343GB, an SS4 rear brake kit built around a 4-piston S4 caliper and a 12.0 inch, 1-piece rotor. It covers rear axles fitted with a GM small pattern 10/12 bolt flange and flush mount bearing housing ends, using a 5×4.75/5×5.00 wheel bolt pattern with 5 lugs.
The backing plate mounts the caliper and houses the park brake shoe assembly. The kit is suited to most wheels 16 inches or larger, and wheel fit is not guaranteed across every wheel style. The powder coated finish and CNC machined aluminum body are made in Phoenix, Arizona.
Key features
- Powder coated Grabber Blue caliper
- Hard anodized aluminum pistons paired with stainless steel abutments
- Dual dust, weather and pressure seals
- Zinc plated, slotted and drilled 1-piece vented rotor
- Stainless braided hoses, DOT approved
- Pad compatibility with DR1 or HB100 pad types
Caring for the finish
The powder coated Grabber Blue finish holds up to normal road and trail use, but it can dull or chip when exposed to harsh chemicals and abrasive grit. Rinse brake dust off the caliper with mild soap and water during regular wheel service, and avoid solvent-based cleaners that can soften the coating. Keep rags and brushes away from the piston seals, which should stay clean and undamaged.
Inspect the caliper and mounting hardware each time the wheel comes off. Look for chips in the coating that expose bare metal, which can start corrosion, and check the hoses for cracking or seepage. A caliper that drags or runs hot after normal driving usually points to a seal, slide or hose problem, so address it before the next trip. Recheck the mounting bolts after the first few runs on rough ground.
- Check caliper coating for chips at each wheel service
- Keep piston seals clean during cleaning
