Overview
The Baer Brakes 4301388R is a red Pro Plus front disc brake system for Chevrolet C10 and GMC C15 half-ton trucks from 1960 to 1986. It is designed for two-wheel-drive trucks running a 2.5 inch drop modular spindle, and it uses a 14 inch two-piece rotor with a six-piston caliper.
Choose this kit when you want Baer’s brake package under one part number, with the front rotors, hubs, brackets and braided hoses all supplied. The system is built for wheels of 18 inches or larger and uses the D0731 pad type.
Key features
- Six-piston fixed caliper with staggered pistons that help reduce uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals protecting against dust, weather and pressure
- Two-piece slot, drill and zinc plated rotor with a billet aluminum hat
- Billet aluminum hubs packed with Redline synthetic grease and billet dust caps
- Powder coated finish on CNC machined forged or billet aluminum parts
- DOT approved steel braided brake hoses
Pad and rotor wear
Pad life on a truck with a drop front end depends on how it is driven. Heavier loads, towing and frequent stop-and-go traffic all increase heat in the front brakes. Two-piece rotors with a separate hat can be serviced more easily than one-piece rotors, because the hat stays on the hub while the friction ring is replaced.
Slotted and drilled rotors help clear debris and gases from the pad surface, but they can show cracks and wear faster under heavy use. Check the friction surface at each pad change, and replace the rotor if it is below minimum thickness or shows heavy scoring. Bed in new pads with a series of moderate stops before relying on hard braking.
- Check rotor thickness at each pad change
- Replace pads in axle sets
- Inspect braided hoses for abrasion near the spindle
- Use brake fluid from a sealed container
