Overview
The Baer Brakes 4302340HO is a rear SS4 Plus brake system for Chevy and GMC C10 2WD trucks in the 60-87 range, with OE large pattern 10/12 bolt C-clip housing ends and a six lug 6×5.50 bolt pattern. It combines a 13 inch two-piece slotted, drilled rotor with a 4-piston S4 caliper in Hugger Orange.
Hugger Orange is the powder coated finish on the S4 caliper, which is made from CNC machined aluminum. Each piston is hard anodized aluminum with stainless steel abutments. The rotor hat is billet aluminum, the kit uses DR1-C pads, and the minimum wheel diameter is 17.0 inch.

Caliper finish care
A powder coated caliper keeps its color best when the surrounding area stays clean. Brake dust, road salt and wheel-well grime can build up around the body and mounting bracket, so a periodic rinse with mild soap and water helps. Avoid harsh solvents on the coating, and keep high-pressure spray away from the bleeder and seals.
The finish is only part of the picture. The pistons, abutments and seals do the work of clamping the pads, so inspect the caliper body for leaks and check that pistons move freely whenever the pads are removed. Keep grease off the rotor surface and replace pads as a set on both sides.
- Rinse the caliper with mild soap and water
- Avoid solvents on the powder coat
- Look for fluid seepage around the seals
- Check that pistons slide freely after pad changes
