Overview
Hugger Orange is the finish on the Baer Brakes 4302542HO, a rear disc brake system for 1960–1988 Chevy and GMC C10 trucks in 2WD form. Its 6-piston caliper and 13-inch slotted, drilled rotor form the core of the kit, aimed at owners of these trucks who want a complete rear brake package.
The mounting uses the OE large pattern 10/12 bolt C-clip housing ends and a 6-lug, 6×5.50 inch bolt circle. The Baer backing plate carries both the caliper and the park brake shoe assembly, and the rotors come pre-assembled with stainless hardware. The 13.0 inch front rotor diameter also applies to this color.

Choosing the right setup
Rear disc brakes change the balance between front and rear braking, which matters most when the truck is loaded or towing. The existing front brakes and the rear proportioning setup should be checked so that the rear does not lock early during hard stops. Pad compound selection follows the same logic, since a pad suited to daily road use may fade under sustained heavy loads.
Trail use adds different demands. Mud, water and rocks can get into the caliper area, so the rotor and pads need inspection after rough outings. Hose routing deserves attention too, because a hose that rubs against a suspension component will wear through. Consider replacing the hydraulic hoses at the same time as the rotors if they are older.
Matching the wheel and tire to the brake package is part of the planning. A larger tire adds rotating mass and can change how much clearance the caliper has, so check fit with the tire you intend to run before the truck goes back on the road.
- Brake fluid matched to what the truck already uses
- Pad compound chosen for the way the truck is driven
- Hose routing checked for clearance around suspension parts
- Rotor surface inspected after the first set of stops

Vehicle fitment
Sorted by decade, the manufacturer list starts with the 1960s entries: C10 trucks, the GMC 1000 and 1000 Series, and Suburban models, including the 1960–1966 GMC Suburban. The 1970s and 1980s entries add C15 and C1500 variants, the Chevrolet R10 in 1987, the R10 Suburban in 1987–1988, and the GMC R1500 Suburban in 1987–1988.
Trucks outside the listed years, and any model not named in the list, are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors arrive pre-assembled, so the bench work centers on the backing plate and caliper. The park brake cables are not included, so existing cables must be used or sourced separately. Check wheels against the Q135H template, since the minimum wheel diameter is 17.0 inch. Work only with the truck safely supported, and bleed the lines after reassembly.
What’s included
The set includes the 6-piston rear caliper system, the two-piece rotor with billet aluminum hat, the Baer backing plate with park brake shoe assembly, and stainless braided hoses with stainless hardware.
Not included: Park brake cables.
