Overview
The Baer Brakes 4301628R is an Extreme Plus front brake system finished with a red 1-piece monoblock 6-piston caliper and a 15 inch 2-piece rotor. Fitment covers 1988–1998 Chevrolet and GMC C1500 2WD trucks, the 1992–1999 C1500 Suburban, the 1995–1999 Chevrolet Tahoe and the 1992–1999 GMC Yukon.
Red powder coat covers the caliper body, which Baer machines from US sourced 2618 aluminum forging in Phoenix, Az. The system is meant for React 2 inch drop spindles that do not come with it, and the pads are the FMSI D1247 type.
Key features
- Red powder coated 6S caliper, a fixed 1-piece monoblock with six pistons
- Stainless pistons, abutments and noise suppression clips
- Pistons staggered to reduce uneven pad wear
- Seal design covers dust, weather and pressure with dual seals
- Caliper body CNC machined from 2618 aluminum forging, US sourced
- Two-piece rotor, slotted and drilled, zinc plated, with a billet hat
Care and maintenance
A red powder coat protects the caliper body, but it still needs regular inspection. Road salt, gravel and trail mud can chip the finish and expose bare metal. Clean the caliper with mild soap and water rather than harsh solvents, and touch up small chips before corrosion spreads under the coating.
Brake fluid absorbs moisture over time, which lowers the temperature at which it boils. Replacing the fluid on a regular schedule, and bleeding the system fully after any hose or caliper work, keeps the pedal firm. Check the reservoir level each time the hood is open, since a dropping level can point to pad wear or a leak.
Billet hubs and their bearings should be inspected for grease condition and play. Repack bearings when the hub is removed, and replace any seals that show cracking. The two-piece rotor should be checked for runout and surface wear whenever the pads are changed.
- Clean caliper and rotor surfaces when the wheels come off
- Replace brake fluid on a set interval
- Check hub bearings for play and grease condition
- Look for pad glazing or uneven wear at each service
