Overview
The Baer Brakes 4301390B is a black Extreme Plus front brake kit built for 2WD 1960–1986 Chevrolet C10 and GMC C15 trucks that run CPP 2.5 inch drop spindles. Its 14 inch two-piece slotted, drilled rotor works with a six-piston monoblock caliper finished in black and set up for 5×5 inch wheels.
The 4301390B is the black-caliper counterpart of the red 4301390R. Baer includes the brackets, braided hoses and hardware, and the billet hubs come with bearings and Redline synthetic grease already in place. Owners matching a black wheel and caliper look will find this is the finish to check against part number.
Key features
- Monoblock six-piston caliper, designated 6S, in black with a one-piece design
- Stainless steel pistons and abutments with noise suppression clips
- Staggered piston arrangement to reduce uneven pad wear
- Dual seals for dust, weather and pressure
- Caliper body CNC machined from forged 2618 aluminum and powder coated
- Two-piece rotor, slotted, drilled and zinc plated, with a billet aluminum hat
- Billet hubs with premium bearings, Redline synthetic grease and billet dust caps
- D1247 pad type with template N117P
Keeping the caliper finish clean
Powder-coated calipers hold up well to normal road conditions, but brake dust and road salt can dull the finish over time. Rinse the wheels and calipers with water after winter driving, and use a pH-neutral wheel cleaner rather than harsh solvents that can lift the coating. A soft brush keeps dust out of the caliper fins and around the slide pins without scratching the surface.
Stainless braided hoses resist abrasion better than rubber lines, yet they still need checks for chafing against suspension parts, especially on a lifted or heavily used truck. Look at the crimped fittings for weeping fluid. Because the spindles are supplied separately, any spindle work should be finished before the new hubs and calipers go on, and the wheel bolts should be checked for torque after the first short drive.

It fits 2WD trucks only, and four-wheel-drive trucks are outside this application. Chevrolet and GMC models after 1986 are outside this application too, apart from the 1987–1989 Chevrolet Suburban. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the drop spindles are not supplied, the truck needs its CPP 2.5 inch spindles in place first. Verify the N117P template and wheel clearance before choosing wheels. Brake components carry safety risk, so a qualified technician should inspect the completed work.

Included with the 4301390B are the two-piece 14 inch rotors, six-piston calipers, billet hubs with bearings, mounting brackets, braided hoses and the hardware set, with the rotors pre-assembled using stainless hardware.
