Overview
The Baer Brakes 4301390HO is a front brake upgrade for classic Chevrolet and GMC C10-series half-ton trucks from 1960 through 1989, with a Hugger Orange 6-piston monoblock caliper. It is sold as a kit built around a 14 inch two-piece rotor, and the 2.5 inch drop modular spindle is not part of the package, so buyers need that piece separately.
The kit is for two-wheel-drive trucks only. Its manufacturer fitment list covers Chevrolet C10 and Suburban models along with GMC 1000, C15 and C1500 trucks, as detailed below. It suits owners who want more braking capacity at the front and who run wheels 18 inch or larger.
Key features
- One-piece monoblock caliper with six pistons, designated 6S, manufactured in Phoenix, Az.
- Caliper body CNC machined from 2618 aluminum forging, with a powder coated Hugger Orange finish.
- Stainless steel pistons, abutments and noise suppression clips.
- Staggered pistons designed to minimize uneven pad wear.
- Dual seals guard against dust, weather and pressure.
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat, 14 inch diameter.
- Billet aluminum hubs with premium bearings packed in Redline synthetic grease and billet dust caps.
Care and maintenance
A front brake setup like this one needs regular attention to keep braking consistent. Pads, rotor faces and caliper slides all wear over time, and small issues such as sticky slides or uneven pad wear tend to show up before a bigger failure does. Checking these parts at routine service intervals is far cheaper than repairing a damaged rotor later.
Because the spindle is supplied separately, the hub and bearing assembly should also be inspected when the brakes are serviced. Clean, properly packed bearings help keep heat and play under control, and they are easier to check while the hub is off the truck.
- Check lug nut torque after the first drive
- Inspect rotor faces for heat checking
- Keep the caliper slides lubricated
- Replace pads before they wear to the backing plate

Installation notes
Rotors arrive pre-assembled with NAS high grade stainless hardware, and the hubs come with bearings already fitted. Mounting brackets, stainless braided hoses and hardware are supplied, but the 2.5 inch drop spindles are not, so they must be in place before the brake components go on. Check wheel clearance against template N117P, since the 14 inch rotor is meant for wheels 18 inch or larger.
What’s included
The kit includes the 6-piston monoblock caliper, the two-piece slotted, drilled and zinc-plated rotors, billet aluminum hubs with bearings and synthetic grease, stainless braided hoses, all mounting brackets and hardware.
Not included: 2.5 inch drop modular spindles.
