Overview
The Grabber Blue Baer Brakes Extreme Plus front disc brake kit, part number 4301107GB, is built for 1978–1988 GM G-Body vehicles and 1982–2003 Chevrolet S10 and GMC S15 pickups. Its 6S caliper is a 1-piece Monoblock design with six pistons, and it clamps a 14 inch two-piece slotted, drilled, zinc plated rotor.
Baer supplies the kit assembled on modified stock height spindles, so the hubs and rotors are set up for the front end of a 2WD vehicle. Baer also lists S10 Blazer and S15 Jimmy versions, which are covered in the fitment section below. The kit uses the popular D1247 pad type.
Key features
- 1-piece Monoblock, 6-piston, 6S caliper manufactured in Phoenix, Az
- CNC machined from US sourced 2618 aluminum forging
- Powder coated finish in Grabber Blue
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled, zinc plated rotor with billet aluminum hat
- Stainless braided hoses and billet dust caps
Wheel fit and clearance
Wheel fit is about more than diameter. Offset, backspacing and the face of the wheel decide whether the caliper and rotor clear the spokes, and a wheel that meets the minimum diameter can still rub. Set up the wheel on the hub before final assembly and check clearance at full steering lock and with the suspension at its normal ride height.
Drilled and slotted rotors shed heat and water quickly, but they can wear pads faster on some street setups and can show cracking near the drilled holes over time. Look at the rotor face and the pad surface during routine brake checks, and replace parts that show cracks, deep grooves or uneven thickness.
Stainless braided hoses hold their shape better than rubber lines under heat, though they still need inspection for chafing against brackets or suspension parts. Brake fluid should be replaced on a regular schedule, since moisture lowers its boiling point.

- Caliper and rotor clearance at full lock
- Braided hose routing away from moving parts

Installation notes
Because the spindles and hubs ship assembled, the front end needs less prep. Compare the N085P template with the wheel you plan to run, since wheel fit can vary by wheel style. Have a qualified brake technician install the kit and check the brakes before the vehicle returns to the road.
