Stop­ping a Square


Street Trucks - - TECH -

IF YOU’VE BEEN a Street Trucks en­thu­si­ast for a while, we’re sure you’ve heard the term “big brakes” or “big brake kit.” Have you ever thought about what those words mean? Ob­vi­ously, a larger set of brakes or a rear disc brake swap will draw the eye to the wheel well, but have you ever thought about the per­for­mance gains you could achieve by swap­ping out the stock brake sys­tem?

We did, so we reached out to Classic Per­for­mance Parts (CPP) for help. Since CPP has been build­ing brake sys­tems for classic trucks for about 25 years, we knew the com­pany would have the right kit for our ’79 C-10 project. Sure enough, CPP of­fers a com­plete bolt-in kit to up­grade the C-10’s front brakes, swap the rear drums for discs, and the kit also in­cludes a brand-new booster and mas­ter cylin­der. Of course, the com­plete kit also comes with all of the nec­es­sary hard­ware and brake lines.

Now that we’ve found a kit for our truck, how will it help our stop­ping per­for­mance? The physics of start­ing and stop­ping are ba­si­cally the same: Ki­netic en­ergy ap­plies to both. Just like a high-per­for­mance en­gine launches a truck off the line when you put your foot on the go pedal, a high-per­for­mance brake pack­age is nec­es­sary to bring the truck to a stop faster when you put your foot on the stop pedal. CPP de­signed its brake pack­ages to main­tain the ef­fec­tive­ness of stop­ping power con­sis­tently.

We will get more into the specifics as we in­stall the in­di­vid­ual com­po­nents. Fol­low along and we’ll show you how to swap out the fac­tory brakes for one of CPP’S com­plete brake kits.
