Overview
The Baer Brakes 4302340GB is a complete SS4 Plus rear brake kit for 60-87 Chevy and GMC C10 2WD trucks, with OE large pattern 10/12 bolt C-clip housing ends and a six lug 6×5.50 inch bolt circle. The Grabber Blue version pairs a powder coated 4-piston S4 caliper with a 13 inch two-piece drilled and slotted rotor.
Hard anodized aluminum pistons with stainless steel abutments sit in the caliper, and the rotor hat is billet aluminum. The backing plate supports the caliper and also houses a one-piece park brake shoe assembly. Pads are the DR1-C type, and the listed minimum wheel diameter is 17.0 inch.

- 2-piece slotted, drilled, zinc-plated rotor with billet aluminum hat

Parking brake planning
The park brake shoe assembly sits in the backing plate, so the parking brake works through the rear unit itself. Before installation, confirm how the parking brake lever will connect to the shoes, since that connection determines the cable length and routing you will need.
Park brake cables are not part of this kit, so sourcing them is a separate step. Measure the path from the lever or pedal to the rear unit, route the cables away from heat and moving suspension parts, and secure them with clips so they do not drag or rub.
- Cable length measured from lever to rear unit
- Routing kept clear of exhaust and suspension
- Cable housings secured with clips
- Parking brake adjusted after the first stops
