Photo 2/20 | Baer Brake Kit 002 | Our ’08 GMC Sierra Crew Cab had just received a new set of 20x10 Black Rhino wheels and these 33x12.5x20 Atturo Trail Blade MT tires. The added rolling weight was just overpowering the stock brakes. The decision to upgrade to a big brake kit was a must for both safety and stopping power.
Photo 3/20 | Baer Brake Kit 003 | We called up Baer and ordered up a set of its 14-inch, one-piece drilled, slotted zinc plated rotors. We would be replacing the front brake discs only.
Photo 4/20 | Baer Brake Kit 004 | The first step was to remove the wheels and tires. As mentioned before, the factory brakes were just not cutting it with our new wheel setup, so the rotor and caliper will be tossed into the scrap pile. And since only the front brakes will be addressed, the rear wheels and tires stayed where they were.
Photo 5/20 | Baer Brake Kit 005 | Using our trusty impact wrench, we quickly buzzed out the top and bottom caliper bolts. The bolts themselves would also be tossed, so no need to clean them up as we normally would have.
Photo 6/20 | Baer Brake Kit 006 | We pulled off the caliper from the bracket and hung it up with a strong piece of wire. It was tucked safely out of the way.
Photo 7/20 | Baer Brake Kit 007 | The brake pads were then removed from the caliper bracket and we went ahead and unbolted it, as well.
Photo 8/20 | Baer Brake Kit 008 | With disassembly almost complete, all that was left to do was to unscrew the retainer screw from the disc and removed the two. We were left with a bare hub.
Photo 9/20 | Baer Brake Kit 009 | The Baer brake kit came with a new set of bolts for the extension bracket and gave them a quick coating of blue Permatex medium-strength threadlocker. It’s just a little insurance for the bolts themselves.
Photo 10/20 | Baer Brake Kit 010 | With the bolts all coated in threadlocker, we went ahead and hand-tightened the supplied 14mmx40mm bolts into the intermediate bracket. It’s recommended to grind down any casting flash on the mounting points, if any. We were lucky no casting flash was present, and no grinding was necessary.
Photo 11/20 | Baer Brake Kit 011 | Baer recommends you tighten down the bracket bolts to 110lb-ft and pull on the bracket as you are bolting it down to properly align it. So we did exactly that, and re-read the instructions after this picture was taken.
Photo 12/20 | Baer Brake Kit 012 | With the bracket installed correctly and torqued down to spec, we were ready to move on to the mounting the disc.
Photo 13/20 | Baer Brake Kit 013 | When compared to the factory disc, the Baer 14-inch disc dwarfs it in both size and performance. Being cross-drilled and slotted it will stop our Sierra like a champ.
Photo 14/20 | Baer Brake Kit 014 | Before we went ahead and re-installed the caliper, we gave it a few quick sprays of a water-based cleaner and degreaser to make it all clean and let it hang for a bit before the disk went back into place.
Photo 15/20 | Baer Brake Kit 015 | We installed the disc back onto the hub. Unlike the factory setup, though, it did not require a retainer screw. We did, however, thread on a lug nut to properly seat the disc and keep it from moving around.
Photo 16/20 | Baer Brake Kit 016 | It was now time to re-install the caliper bracket, and lock it down to the Baer intermediate bracket. We used the caliper mounting bracket bolts that were supplied in the kit to do so.
Photo 17/20 | Baer Brake Kit 017 | Here is shot of how the caliper bracket and the Baer bracket fit together.
Photo 18/20 | Baer Brake Kit 018 | With all the mounting bolts torqued to spec, our new Baer big brake kit was taking shape. It was time to slide in the pads and bolt in the factory caliper.
Photo 19/20 | Baer Brake Kit 019 | You may notice, as we did, a small amount of the caliper extends out beyond the outer diameter of the rotor. This is a purposeful design feature that allows the caliper to clear the larger rotor and has no effect on performance.
Photo 20/20 | Baer Brake Kit 020 | With the new Baer brake kit fully installed, we mounted up the wheels and tires. Our bigger brakes look much more proportionate in the larger wheel space, and more importantly, will stop our truck more efficiently.
