Overview
The Baer Brakes 4302541MG is a Monster Green Pro Plus rear brake system for 1960 to 1988 Chevrolet and GMC C10-series 2WD trucks with 5 lug, 5×5.00 inch wheels. Its 6P caliper and two-piece slotted, drilled rotor are paired on a backing plate that houses a park brake shoe assembly, so the kit covers both service and parking braking at the rear.
The Monster Green caliper is powder coated and CNC machined from US sourced forged or billet aluminum in Phoenix, Arizona. Both the front and rear rotors measure 13.0 inch outside diameter, and they come pre-assembled with NAS high grade stainless hardware. The 13 inch Pro Plus suits most wheels 17 inch or larger, but fit with every wheel style cannot be guaranteed, so check the Q135H template against your wheel.
Key features
- Monster Green powder coated caliper finish
- Staggered six-piston layout to reduce uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled and zinc-plated rotor with billet aluminum hat
- Vented rotor construction
- Steel braided hoses carrying DOT approval
Off-road and rotor protection
Rotors on trucks used off pavement face mud, rocks and water crossings. Water can cool a hot rotor quickly, which may cause surface stress over time, and mud packed into the caliper can slow release. Slotted and drilled rotors help shed water and debris, but they still need periodic checks for cracks and heat marks.
After water crossings or deep mud, let the brakes dry out and test the pedal before driving fast. Wheel fit matters here too, because a rotor that rubs the caliper or backing plate can overheat quickly. Keeping the rotor face clean at each wheel swap helps the pads grip evenly.
- Mud and grit behind the backing plate
- Rotor cracks and heat discoloration
- Pedal feel after water crossings
- Caliper dust boots after trail use
- Wheel clearance checked against the Q135H template

Installation notes
Before the rotor is fitted, hold the Q135H template against the wheel you intend to use and check clearance. Park brake cables are not included, so plan the parking brake connection before the truck is returned to service. Rear brake work calls for an experienced installer, and a brake fault at the rear axle is a hazard.
What’s included
The set includes the Monster Green 6P caliper assembly, two-piece 13.0 inch rotors with pre-assembled NAS high grade stainless hardware, the backing plate with its one-piece park brake shoe assembly, and stainless braided hoses with hardware.
Not included: Park brake cables.
