Overview
The Baer Brakes 4301390CY is a Comp Yellow Extreme Plus front brake kit for 60-87 Chevy/GMC 2WD 1/2 ton trucks with a 5 lug, 5×5 inch wheel pattern. It is built for GM C10 truck owners who want 14 inch rotors and a 6-piston caliper up front.
A 1-piece Monoblock 6-piston 6S caliper clamps a 14.0 inch two-piece slotted, drilled and zinc plated rotor. The caliper is powder coated in Comp Yellow and uses stainless steel pistons, abutments and noise suppression clips, with staggered pistons to reduce uneven pad wear. Dual seals handle dust, weather and pressure, and the pads are the D1247 FMSI type.
Key features
- Monoblock 6S caliper with stainless steel pistons and abutments
- Staggered piston layout intended to reduce uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled and zinc-plated rotor with a billet aluminum hat
- Billet aluminum hubs with premium bearings packed in Redline synthetic grease
- Powder coated caliper in Comp Yellow
- Stainless braided hoses and mounting brackets included
Pads and rotor wear
Pad choice affects bite, dust and how quickly the rotor surface wears. Friction material that suits street driving can glaze under heavy use, while more aggressive compounds may wear faster and create more dust on wheels. Match the pad to how the truck is driven, and bed the new pads in gradually so the surface transfers evenly to the rotor.
Slotted and drilled rotors help clear gas and debris from the pad face, but they still wear with use. Check for cracks radiating from the drilled holes and for a pulsing pedal, which can point to thickness variation. A rotor that is worn near its minimum thickness should be replaced rather than reused.
- Bed in new pads with several moderate stops
- Check caliper pins for smooth sliding
- Look for uneven pad wear on both pads
- Replace rotors in pairs

Installation notes
The w/Cpp 2.5 Inch Drop Modular Spindle (5 Lug, 5x5BC) is not included in this kit, so plan for it before the rotors go on. Compare Template N117P with your wheel first. The 14 inch system is designed for most 18 inch or larger wheels, but wheel fit cannot be guaranteed for every style.
After the braided hoses are installed, bleed the brake fluid through the full system and check for firm pedal travel before driving.
What’s included
Contents are the 6S Monoblock caliper, 14.0 Inch rotors pre-assembled with stainless hardware, billet aluminum hubs with bearings and dust caps, mounting brackets, stainless braided hoses and hardware.
Not included: the 2.5 inch drop modular spindle.
