Overview
The Baer Brakes SS4 Plus 4302334GB is a Grabber Blue rear disc brake kit built around a 4-piston S4 caliper and a 13 inch two-piece slotted, drilled rotor. It is intended for rear axles with GM 10/12 bolt C-clip housing ends in the small car pattern and wheels on a 5×4.75 or 5×5 inch bolt circle.
Match the axle flange and bolt pattern to your axle before judging whether this kit suits it. Baer makes the caliper in Phoenix, AZ from US-sourced forged or billet aluminum.
Key features
- Grabber Blue powder coated finish on the S4 caliper
- Four-piston floating caliper with hard anodized aluminum pistons
- Two-piece slotted, drilled, zinc-plated rotor on a billet aluminum hat
- Rotor pre-assembled with NAS high grade stainless hardware
- Dual dust, weather and pressure seals with noise suppression clips
- Stainless braided, DOT approved hoses and hardware included
Things to check
Before installation, look over the hub face and wheel studs. A warped or rusted hub surface can cause pulsation even when the new rotor is sound. Clean the mounting surface thoroughly so the rotor sits flat against it.
Wheel offset affects how much room the caliper has, so test fit the wheel before final assembly. Parking brake cables are often reused from the original setup or bought as a separate part, and it helps to confirm their length before work begins. Once the brakes are in service, watch for squeal, pulsing or longer stopping distances as signs the pads or rotor need attention.
- Clean the hub face before mounting the rotor
- Test fit the wheel with the caliper in place
- Check the old parking cable length and condition
- Watch for pulsing under light braking
- Replace pads when wear indicators start to sound

Vehicle fitment
Its axle flange is GM 10/12 bolt C-clip, small car pattern, the wheel bolt pattern is 5×4.75/5×5.00, and the minimum wheel diameter is 17.0 inch. These are the measurements to match against your axle and wheels.
Installation notes
Park brake cables are excluded from this kit, so the parking brake needs separately sourced cables. Hold the planned wheel against the S135H template to confirm clearance. Match replacement pads to the DR1-C pad type, and bed in new pads with a series of moderate stops first.
What’s included
The S4 caliper, two-piece rotor with stainless hardware, backing plate housing the 1-piece park brake shoe assembly, and stainless braided hoses with hardware.
