Overview
The Baer Brakes 4301627CY is a front Extreme Plus brake kit in Comp Yellow for Chevrolet and GMC C1500 2WD trucks from 1988 to 1998 and C1500 2WD SUVs from 1992 to 1999 that run React 2 inch drop spindles. Its caliper is a 1-piece Monoblock, 6-piston, 6S design clamped to a 14 inch, 2-piece slotted, drilled, zinc plated rotor.
Anyone upgrading the front brakes on these trucks gets the caliper, rotor and hub in one package, along with stainless braided hoses and the brackets that mount them. The caliper uses D1247 pads by FMSI number, and the finish is a Comp Yellow powder coat over the aluminum body.
Key features

- Caliper body CNC machined from a US-sourced 2618 aluminum forging
- Comp Yellow powder coat finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals against dust, weather and pressure
- Slotted, drilled, zinc plated 2-piece rotor with a billet aluminum hat, fitted with NAS stainless hardware
- Billet hubs carry premium bearings packed with Redline synthetic grease
Keeping the brakes in shape
Rotors on a truck this size see heavy heat, so inspect the friction surface at pad changes for scoring, grooves and a raised lip at the outer edge. Pulsing through the pedal often points to uneven thickness or runout rather than a problem with the caliper itself.
The Comp Yellow powder coat holds up to normal cleaning, but harsh solvents and high-pressure washing near the caliper seals can lift it over time. Wipe the caliper with a mild cleaner after trail or track use and keep the hose fittings dry and free of grit.
- Inspect rotors for scoring and lip wear at each pad change
- Keep the caliper finish clean with a mild cleaner
- Check hose fittings for weeping after the first drive
