Overview
The Baer Brakes 4301682S-2 is a front 6T brake kit in Silver for GM C/K 1500 trucks from 1999 to 2025 and GM C/K 1500 SUVs from 2000 to 2025. Its 2-piece, 6-piston direct mount caliper clamps a 1-piece vented, slotted and zinc-plated rotor that measures 13.5 inch across, making it a front disc upgrade for Chevrolet, GMC and Cadillac full-size trucks and SUVs.
Baer machines the caliper from forged or billet aluminum and powder coats it. The stainless steel pistons use staggered placement, which is designed to minimize uneven pad wear. Dual seals guard against dust, weather and pressure. Mounting brackets, steel braided hoses and hardware come with the kit. Baer designed it to fit most wheels 17 inches or larger.

Before you buy
A front brake upgrade affects more than the caliper. The pads, rotor and hoses work as one system, so replacing only one part can leave the others at mismatched wear levels. When the caliper changes, the pad type and rotor thickness need to match what the caliper was designed to clamp.
Trucks that have been lifted or fitted with larger tires put more stress on brake lines and change the angle of the hose, so hose length should be checked on the actual vehicle. Steering components and wheel clearance also matter, since the front wheels pivot through a wider arc. Check the front suspension for play before a big brake install, because loose parts can shift the rotor.
- Confirm the pad compound suits how the truck is driven, towed or used off road
- Bleed the system after any hose or caliper change
- Recheck caliper bolts after the first few stops

Installation notes
The hoses are sized for stock-height vehicles, so a lifted truck may need longer hoses. Check clearance with the O080M template against the wheels you plan to use, since the minimum wheel diameter is 17.0 inch. Because brakes are safety-critical, have a qualified technician inspect the completed installation before the vehicle goes back into service.
What’s included
The kit includes the 6T caliper, the 1-piece rotor, the mounting brackets, the steel braided hoses and the hardware.
Not included: wheels and tires, and the longer hoses a lifted vehicle may need.
