Overview
The Baer Brakes 6T front brake kit in Black, part 4301682B-2, is made for full-size GM pickups and SUVs. It pairs a 13.5 inch vented rotor with a six-piston 6T caliper and fits GM C/K 1500 trucks from 1999 to 2025 and SUVs from 2000 to 2025.
The package includes a slotted, zinc-plated 1-piece rotor, the 6T caliper, stainless braided brake hoses, mounting brackets and hardware. Baer rates the kit as performance grade and names the D1247 pad type for the pads.

Before you buy
A front brake upgrade on a full-size truck or SUV changes more than stopping power. A larger rotor and a multi-piston caliper add weight and heat capacity, so the steering knuckle, wheel bearings and hub should be inspected before installation. Wheel clearance matters just as much, since a bigger caliper body sits closer to the spokes of the wheel. Measure the inside of your wheels and compare them with the template before committing to the kit.
Consider the brake pads as part of the system. Pads matched to the caliper and rotor keep wear even and reduce noise. Replacing the rotors and pads on the same axle at the same time gives a more consistent pedal feel than mixing old and new components. Brake fluid should also be fresh when the system is bled, because moisture lowers its boiling point under repeated stops.
- Check wheel bearings and ball joints for play before fitting
- Replace pads and rotors on the same axle together
- Use fresh brake fluid when bleeding the new lines

Installation notes
The hoses are built for stock-height vehicles, so lifted trucks may need longer ones. Because Baer cannot guarantee fit with every wheel style, check wheel clearance with its O080M template first. Have an experienced technician install the kit and bleed the brake lines.

The kit includes the Black 6T caliper, the 1-piece slotted rotor, stainless braided hoses, mounting brackets and all necessary hardware.
Not included: wheels of at least 17 inches in diameter.
