Overview
Fire Red is the finish on the Baer Brakes 4302485FR, a rear disc brake system built around a 14.0 inch two-piece slotted, drilled rotor and a six-piston caliper. The target trucks are 2WD Chevrolet and GMC C10 models from the 60-87 range with a 5 lug, 5×5 inch bolt pattern and large pattern 10/12 bolt C-clip housing ends.
Baer’s one-piece park brake shoe assembly sits inside the backing plate, which also serves as the caliper mount. The rotor is supplied with NAS high grade stainless hardware already installed, so the rotor and hub come as a prepared unit. Dual seals guard the caliper against dust, weather and pressure, which suits owners who want the caliper color to match a restored truck.
Key features
- Six-piston caliper with stainless steel pistons, abutments and noise suppression clips
- Pistons staggered to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slot, drill and zinc-plate rotor paired with a billet aluminum hat
- Billet or forged aluminum caliper parts, CNC machined and powder coated
- Stainless braided hoses with DOT approval
- Pads specified by the D0731 FMSI type
Wheel clearance and first drive
Wheel clearance is the most common reason a rear caliper kit has to be reworked. Offset and backspacing change how close the caliper sits to the spokes or inner barrel, so a wheel that clears the template on the bench may still rub once the truck is loaded. A fresh tire can also grow the stack height enough to change clearance.
The first drive after a brake job should be slow and deliberate. Test the pedal feel, listen for rubbing at low speed, and check the wheel after a short run for heat or smell. Parking brake function deserves the same attention, since the rear shoe assembly sits in the same backing plate as the caliper.
- Measure wheel backspacing before buying new wheels
- Recheck clearance after any tire size change
- Feel each wheel for unusual heat after the first run
- Test the parking brake on a slight grade

Installation notes
Compare the Q135P template against the wheel you plan to use before mounting, since fit is not guaranteed across every wheel style. Confirm clearance at the caliper and rotor, then test the brakes at low speed in a clear area.
