Overview
The Baer Brakes 6T front brake system, part number 4301682GG-2, is a complete front disc brake kit with a six-piston 6T caliper finished in Graphite Gray and a 13.5 inch vented rotor. It fits GM C/K 1500 trucks from 1999 to 2025 and GM 1500 SUVs from 2000 to 2025, including the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, GMC Yukon and Cadillac Escalade.
The kit replaces the stock front brakes with a 1-piece slotted and zinc-plated rotor, a direct-mount caliper, stainless braided hoses, mounting brackets and hardware. The rotors use a curved vane design to support cooling, consistent braking and reduced brake fade, and the pads use the common D1247 pad type.
Key features
- Six-piston, direct-mount 6T caliper with a powder-coated Graphite Gray finish
- Caliper CNC machined from US-sourced forged or billet aluminum
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 1-piece slotted and zinc-plated vented rotor, 13.5 inch diameter
- Stainless braided hoses and all mounting brackets included
- Dust and weather seals are T compliant.
Before you buy
A front brake upgrade on a full-size truck changes more than the rotor. Pad compound, rotor thickness and hose length all affect how the front end stops and how the pedal feels, so it helps to review them together rather than swapping one part at a time. Heavier tires and towing loads put extra heat into the front brakes, which makes cooling capacity and pad choice worth considering before you order.
Front rotors and pads are often replaced together, and a caliper change usually calls for new hoses and fresh fluid. After the first few drives, inspect the rotor surface and check the pads for even contact and wear. If the pedal feels soft, vibrates under braking or the truck pulls to one side, stop driving it and have the system inspected by a qualified technician.

Installation notes
The hoses are sized for stock-height vehicles, so a lifted truck may need longer hoses. Baer recommends checking wheel clearance against its O080M template before mounting, because it cannot guarantee fit with every wheel style. Brake work should be done by someone experienced with hydraulic systems, including bleeding the lines afterward.
What’s included
The kit includes the 6T caliper, the 1-piece slotted and zinc-plated rotor, stainless braided hoses, all mounting brackets and the hardware needed for installation.
Not included: wheels, which need to be at least 17 inches in diameter.
