Overview
Baer Brakes part 4302332HO is an SS4 rear brake kit with Hugger Orange caliper finish. It couples a four-piston S4 caliper with a 12 inch, 1-piece slotted, drilled, zinc-plated rotor and is aimed at rear axles using a GM small pattern 10/12 bolt bearing-on-axle flange with 5×4.75/5×5.00 wheel bolts.
Baer’s backing plate supports the caliper and holds the 1-piece park brake shoe assembly. Pad types listed are DR1 or HB100, and the dust and weather seals are T compliant. Stainless braided hoses come with the kit.
Key features
- Four-piston S4 caliper, manufactured in Phoenix, AZ
- Forged or billet aluminum, CNC machined from US-sourced stock
- Powder coated finish
- Hard anodized aluminum pistons, stainless abutments and noise suppression clips
- Dual dust, weather and pressure seals
- Slotted, drilled, zinc-plated 1-piece rotor
- Stainless braided hoses included
Care and maintenance
Caliper finish holds up best with routine cleaning. Brake dust and road grime can build up around the powder coated body, so a mild wheel cleaner and soft brush keep it looking clean. Avoid harsh solvents on rubber seals and boots, since they can soften them over time.
Bleeding and hose care matter as much as the finish. Braided hoses should be checked for chafing where they pass near suspension components, and any sign of bulging or leaking calls for prompt replacement. After any hose or caliper work, bleed the system until the pedal feels firm and consistent, then check the reservoir level.
- Inspect braided hoses for chafing at each service
- Wipe the caliper body with a mild cleaner
- Check pad thickness at each wheel removal
- Bleed until the pedal feels firm

Vehicle fitment
No vehicle is named for this kit, and no years or chassis codes are given. The application is defined by the rear axle, so the S113E template is the practical way to confirm a match.
Before ordering, confirm the year, model and trim match your vehicle. Fit with a specific wheel style cannot be guaranteed, so compare the S113E template with the chosen wheel.
Installation notes
The park brake shoe assembly lives inside the backing plate, which doubles as the caliper mount. The 16.0 inch minimum wheel diameter and 1.02 rotor thickness make a template-to-wheel check worthwhile before mounting. Use jack stands rated for the vehicle and confirm the parking brake releases during bench checks.
What’s included
The kit covers the S4 caliper, the 12 inch 1-piece rotor, the backing plate with its park brake shoe assembly, and the stainless braided hoses.
Not included: park brake cables.
