Overview
The Baer Brakes 4301368HO is a Pro Plus front disc brake kit for 1978-1988 GM G-body vehicles and S10/S15 2WD pickups, plus the S10 and S15 Blazer and Jimmy, finished with a Hugger Orange six-piston caliper. Each kit comes with billet hubs already assembled on stock height spindles.
Stock height spindles keep the front end at factory geometry instead of raising or lowering it. The rotor measures 14.0 inch, the bolt pattern is 5×4.75, and the wheel studs are M12-1.50 x 51.5mm.
Key features
- Six-piston fixed caliper in Hugger Orange, assembled in Phoenix, Arizona
- Two-piece 14.0 inch vented rotor, slotted, drilled and zinc plated, with a billet aluminum hat
- Stainless steel pistons and abutments with noise suppression clips
- Staggered pistons to help limit uneven pad wear
- Dual seals for dust, weather and pressure
- Billet hubs with premium bearings, Redline synthetic grease and billet dust caps
- Stock height spindles included with the hubs
Hub bearings and seals
Billet hubs carry the wheel bearings, so their condition affects both braking and steering feel. Bearings lubricated with synthetic grease need less frequent attention than conventional grease, but they still benefit from periodic inspection for play, roughness or heat. When the hub is off for pad or rotor work, look at the seal lip and bearing surfaces for wear before reassembly.
Dust caps and seals keep water and grit out of the bearing. A cap that has cracked or loosened lets moisture in, which can lead to early bearing failure and rust on the hub face. Clean the surfaces with a light solvent, dry them, and replace any seal that shows cuts or hardening rather than trying to reuse it. Torque the axle hardware to the specified value and recheck after the first few drives.
- Bearing play checked by hand with the wheel off
- Seal lips inspected for cuts or hardening
- Dust cap seating confirmed after reassembly
- Hub surfaces kept clean and dry before installation

Installation notes
No separate spindle work is needed because the hubs are already mounted on stock height spindles. Wheel studs are metric, M12-1.50 x 51.5mm, so use wheel hardware with that thread. Confirm wheel clearance with the Q082P template and the 18.0 inch minimum wheel diameter. Keep the vehicle supported on secure stands while working at the front.
What’s included
The kit includes Hugger Orange six-piston front calipers, 14.0 inch rotors with stainless hardware, billet aluminum hubs on stock height spindles, mounting brackets, stainless braided hoses and hardware.
