Overview
The Baer Brakes 4302541FR is a Pro Plus 13.0 inch rear brake kit finished in Fire Red, made for 2WD GM C10 trucks from the 1960 to 1987 range. A six-piston 6P floating caliper clamps a 13 inch two-piece slotted, drilled and zinc-plated rotor, with a 5 lug, 5×5 inch hub layout.
Baer manufactures the caliper in Phoenix, Arizona. The backing plate acts as the caliper mount and also contains a one-piece park brake shoe assembly, which keeps the parking function at the rear axle inside the same unit. Rotors come pre-assembled with NAS high grade stainless hardware, and the system is designed for the Large Pattern 10/12 bolt C-clip housing ends.
Key features
- Fire Red powder coated finish on the 6P caliper
- Two-piece slot, drill and zinc-plated 13 inch rotor with billet aluminum hat
- Stainless pistons, abutments and noise suppression clips
- Staggered piston layout to minimize uneven pad wear
- Dual seals rated for dust, weather and pressure
- T compliant dust and weather seals
- Braided brake hoses, DOT approved, with hardware
On the trail and in traffic
Rear disc brakes shed heat faster than drums, which helps when the truck is loaded or going down a long grade. Heat still builds on steep descents, so use lower gears and avoid resting a foot on the pedal. Good airflow around the rotor and caliper keeps fade in check.
Off-road use brings mud, sand and water into the brake area. Rinse the assembly after deep wading when it is safe to do so, and check the dust seals for cracks after heavy trail use. Trapped water and grit under the pads can cause squeal and uneven wear.
- Check pad thickness at every tire rotation
- Look for scoring on the rotor face
- Inspect braided hoses for chafing near the axle
- Keep the parking mechanism clean and free of grit

Installation notes
Clearance is the main check on this kit. Lay the Q135H template against the wheel you intend to run, because Baer warns that wheel design, not only diameter, decides whether the caliper clears. Park brake cables are not part of the package, so inspect the cable routing on your truck before the rear is assembled.
What’s included
The package includes the rear 6P caliper, the 13.0 inch two-piece rotor with pre-assembled stainless hardware, the backing plate with the one-piece park brake shoe assembly, and braided brake hoses with hardware.
Not included: park brake cables.
