Overview
The 4301628CY is an Extreme Plus front brake kit with 15-inch two-piece slotted, drilled and zinc-plated rotors and 1-piece Monoblock 6-piston, 6S calipers. It fits 1988-1998 Chevrolet C1500 and GMC C1500 trucks, plus 1992-1999 Suburban, 1995-1999 Tahoe and 1992-1999 Yukon models in the 2WD configuration.
The kit uses stainless steel pistons, abutments and noise suppression clips, staggered pistons to reduce uneven pad wear, and dual dust, weather and pressure seals. Pads are the D1247 FMSI type. Rotors arrive pre-assembled with NAS high grade stainless hardware, and billet aluminum hubs come with premium bearings packed with Redline synthetic grease and billet dust caps.

Choosing the right rotor
Rotor size affects both braking feel and how much room the wheel needs. A larger diameter gives more leverage against the pads, but it also takes up more space behind the spokes. Choosing a rotor is therefore a matter of matching it to the wheel, the tire and the typical load rather than picking the biggest option.
Hat and rotor surfaces are worth inspecting as the truck ages. A slotted or drilled face helps clear debris and gases, though it can wear the pad faster if the pad is not suited to it. Rotor hats should sit flat against the hub, so check the mounting faces during every service.
- Confirm wheel clearance before choosing a rotor size
- Inspect the hat and hub mounting surfaces at each service
- Consider pad compound together with rotor surface

Vehicle fitment
The manufacturer fitment list includes 1988-1998 Chevrolet C1500, 1992-1999 Chevrolet C1500 Suburban, 1995-1999 Chevrolet Tahoe, 1988-1998 GMC C1500, 1992-1999 GMC C1500 Suburban and 1992-1999 GMC Yukon.
The listed fitment covers 2WD trucks and SUVs of these years. 4WD models and 1999 C1500 trucks are not on the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The fitment notes call for React 2 Inch Drop Spindles, which are not included, so confirm the spindles are in place before the kit is fitted. Baer cannot guarantee fit with every aftermarket wheel, so use the N117U template to compare the rotor and caliper with the wheel you plan to run. The 15 inch system fits most 19 inch or larger wheels. Brake work carries real risk, so have the system installed by a qualified technician.
What’s included
The kit includes the 6S Monoblock calipers and 2-piece rotors pre-assembled with NAS high grade stainless hardware, billet aluminum hubs with premium bearings and billet dust caps, all mounting brackets, stainless braided hoses and hardware.
Not included: React 2 Inch Drop Spindles.
