Overview
The Monster Green Pro Plus is a rear disc brake system for 1960-1986 Chevrolet C10 and GMC C15 trucks with five-lug wheels. Its 6-piston caliper squeezes a 14-inch two-piece rotor, and the kit is designed for 2WD trucks.
The backing plate supports the caliper and houses a one-piece park brake shoe assembly. Stainless hardware comes already fitted to the rotors. The 14-inch Pro Plus is sized for most 18-inch or larger wheels, though wheel styles differ, so test fit with the template before choosing a wheel.

Street and trail driving habits
Drivers who move from drum brakes to discs often notice a firmer pedal and more consistent stopping, but the change also shifts how the truck behaves in hard braking. Test the brakes at low speed in an empty area before taking the truck on a highway. On dirt roads, disc brakes can pick up mud and grit, so rinse the rotors and caliper after deep puddles or trail runs.
Brake fluid should be fresh after any brake work, because moisture lowers its boiling point and can soften pedal feel under heavy use. Inspect the front brakes too, since uneven braking between the front and rear can pull the truck. Keep an eye on the pad wear indicators and the rotor surface at each oil change.
- Test brakes at low speed before highway use
- Rinse mud and grit off after trail runs
- Change brake fluid after brake work
