GM really hit a homerun when they launched the new '07 Silverado and Sierra. New body styling, great interiors, powerful engine combos, and good mileage make these truck fantastic choices for a daily driver or show rig. One area, however, where GM skimped to save money was with the rear drum brakes. Stating that rear discs were too costly, the drums were slapped back on and the braking chores left to the ABS computer to modulate between front and rear pressures. SSBC has a great solution to this dilemma with its new Force 10 Tri-Power rear disc conversion with three-piston calipers, 12-inch rotors, and built-in parking brake. The kit is bolt-on, can be ordered in multiple colors to add a custom touch, and best of all, vastly improves the stopping power of the newer GM trucks. During a recent SEMA truck build, we made sure to chronicle the install of SSBC's new rear disc conversion and we also snapped pics of the new Force 10 Tri-Power three-piston aluminum caliper with 14-inch rotors for the front of the '07 GMC. Check out the photos as we easily upgraded the stopping power by 36 percent and did so with basic handtools in the garage.
From The Driver SeatFirst off, the GMC stops easily with minimal pedal depression. With the addition of the large 22- and 24-inch wheels, big brakes were a must and the SSBC Force 10 front and rear kits performed very well. The frontend doesn't nose plow nearly as bad now that the rear brakes are clamping down with a big bite. In the looks department, there is no contest as the SSBC bright-red, aluminum calipers helped to add a performance look from behind the billet wheels. This upgrade was a huge success and though we did spend a little over $3,000 on front and rear brakes, it does make a huge difference when you apply the brake pedal and you're confident the truck will stop.

Out of the boxes from SSBC, we pulled out the front and rear brake kits that included aluminum calipers, vented rotors, and the necessary hardware for the install.

FrontWith the truck up on jackstands and the wheels off, we took a look at the factory front brakes. Whereas they stopped the factory 17-inch wheels/tires well, the new 22-inch wheels really taxed the system. And besides, these brakes don't belong on a show truck that is going to be driven.

A -inch ratchet and metric socket were used to break free the caliper mounting bolts. The caliper and rotor were then removed.
