Overview
The Baer Brakes 4301107HO is an Extreme Plus front disc brake kit in Hugger Orange for GM G-Body and S10/S15 vehicles. Its one-piece monoblock six-piston caliper clamps a 14 inch rotor, and billet hubs with pre-assembled spindles are included.
Manufacturer fitment covers Buick Regal, Chevrolet El Camino, Malibu, Monte Carlo, S10 and S10 Blazer, GMC S15 and S15 Jimmy, Oldsmobile Cutlass and Cutlass Supreme, and Pontiac Grand Prix. Owners who want the orange finish on those models get the same 14 inch rotor and D1247 pad type as the other Extreme Plus color options.
Key features

- Caliper CNC machined from US sourced 2618 aluminum forging
- Hugger Orange powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Pistons staggered to minimize uneven pad wear
- Dual dust, weather and pressure seals
- 14 inch two-piece slotted, drilled, zinc plated rotor on a billet aluminum hat
- D1247 pad type (FMSI D1247)
Before you buy
Large front brake kits change how the whole front end behaves, so it helps to think about the system as a set. A bigger caliper and rotor add stopping capacity and heat capacity, but they also add weight to the spindle and hub, and that load moves through the steering and suspension. Drivers who run a heavier wheel or tire should look at the total package before assuming the brakes will feel the same as stock.
Pad choice matters as much as the caliper. Pads are matched to the rotor material and the way the vehicle is used, so a street driver and a trail driver will often prefer different compounds. Check pad wear at each service and look for uneven wear, glazing or a pulsing pedal, which can point to a warped or worn rotor.
- Brake hose condition and fittings after install
- Lug nut torque after the first wheel removal
- Fluid level after bleeding the new calipers

Installation notes
The billet hubs and spindles come assembled, so the install centers on the caliper, rotor and braided hose connections with their included brackets. Wheel clearance is the first check: the listed minimum wheel is 18.0 inch, and the N085P template is the comparison Baer recommends. A qualified technician should check the finished brake system before road use.
What’s included
Supplied items are the one-piece monoblock caliper, two-piece rotors with pre-assembled NAS high grade stainless hardware, billet aluminum hubs with premium bearings and Redline synthetic grease, billet dust caps, spindles, brackets, stainless steel braided hoses and hardware.
Not included: wheels.
