Overview
The Baer Brakes 4302334S is a silver SS4 Plus brake kit for rear axles with GM 10/12 bolt C-clip housing ends in the small car pattern, with 5 on 4.75 and 5 on 5 inch bolt circles. The kit pairs a four-piston S4 caliper with a 13 inch two-piece slotted, drilled rotor and a park brake shoe assembly.
The backing plate mounts the caliper and houses the one-piece park brake shoe assembly. The 13 inch SS4 Plus fits wheels 17 inches or larger, and the caliper is finished in silver.

Before you buy
Rear brake kits for C-clip axles work as a matched set. The caliper, rotor, backing plate and park brake shoes all have to suit the axle flange and wheel before the kit goes on the vehicle. Start by confirming the flange style, the bolt pattern and the template, then check wheel clearance with the rotor and caliper together, since the rotor diameter sets how much room the wheel needs around the brake.
Park brake function deserves attention with this type of kit. Because the shoes sit in the backing plate, the cable set and adjustment must be sorted out during installation. Route the cables by hand against the axle tube and trailing arms before bleeding the lines, so the parking brake engages cleanly once the system is complete.
- Check wheel bore and offset before settling on a rotor size
- Replace any brake hose that shows cracking or swelling
- Re-check caliper bolts after the first few drives
- Bed in new pads with a gradual stop-and-cool routine

Vehicle fitment
Fit depends on your vehicle’s year, model and trim. Confirm fit before ordering by matching the axle flange, the 5×4.75/5×5.00 bolt pattern and template S135H against your rear axle.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Park brake cables are not included, so the park brake shoe assembly in the backing plate needs a separate cable set. Baer recommends comparing the S135H template with your wheel before installation. Brake work is safety-critical, so have a qualified technician verify the installation.
What’s included
The kit includes the silver S4 four-piston caliper, two-piece 13 inch rotors pre-assembled with stainless hardware, the backing plate with park brake shoe assembly, and stainless braided hoses.
