POL offers an assortment of braking components for '67-72 Chevy trucks, and we chose a package that covers everything needed and more. Starting at all four corners, the package we chose comes with four 12-inch rotors with GM ratcheting calipers and performance brake pads. For some added performance and looks, we also chose to go with the optional cross-drilled and slotted rotors. The front rotors come complete with new bearings and seals. By the way, POL offers packages for either five-lug or six-lug vehicles; we went with a five-lug set. We bought the deluxe kit, which comes with the option of stock replacement spindles or 2.5-inch drop spindles, which we ordered. Another benefit to running the new POL drop spindles is their later-model '73-87 control arm ball joints and outer tie rod ends, which make future replacement easy and simple. The kit also comes complete with inner tie rods and adjusting sleeves. Another item included is rubber flex hoses, but instead of using rubber hoses, Project Get Shorty is going to receive the 10mm stainless brake hoses, which not only look cool, but also add to the performance of the brake system due to the fact that the hoses won't flex and pulse. In back, we also ordered new emergency brake cables to hook up the GM calipers to the '71 factory e-brake setup.
One other area that also needs to be upgraded when doing a four-wheel disc setup is the master cylinder and booster. Whenever you use a four-wheel setup, you need to use a dual master cylinder. Another necessary upgrade is the booster. The proper booster needs to be used to ensure that all four corners get the adequate amount of psi to operate the brakes at their fullest potential. For our setup, POL provided us with a dual master cylinder and a dual-diaphragm 8-inch power booster. Besides the fact that the setup is more than enough to stop the truck, it also converts the truck from manual brakes to power brakes. On top of that, Shorty is also going to utilize a self-proportioning valve, which will provide a sufficient amount of braking to keep the rear brakes from locking up.
Well, until next month, it's off to the Primedia Tech Center to get rockin' on installing these parts.
