Project Impala Part Two By Jim Aust Courtesy of Rod & Custom Magazine     The latest dropped spindle and big brake kit from Classic Performance Products comes with everything to get your '58-64 fullsize Chevy stopping, handling, and looking better all in one shot. Kits for many other makes, models, and years are also available. When it comes to brakes on a car, bigger is always better. Beacause of that fact, Classic Performance Products decided to go with their new complete 1958-64 front brake kit along with their latest 2-inch drop spindles on their Project ' 62 Impala. The new big brake front system uses 13-inch cross-drilled, gas-slotted and zinc washed rotors, mounted to 2024 T6 billet aluminum CNC machined hubs with PBR C15 calipers that attach to the spindles with CPP custom caliper mounting brackets. The PBR C15 calipers have twin 52mm pistons and a larger brake pad surface that offers about 60-percent more stopping power in the caliper than the popular C5 caliper at about hall the cost. This new spindle can be used on ful1size Chevys up to 1910 with a wide range, of disc brakes, from stock to the popular 11-12- and 13-inch kits available. Cast from high-qualiiy Ductile Iron with 4140 Chromoly CNC-machined pins, these spindles accept factory ball joints and stock steering arms. It should be noted that these 2-inch dropped spindles cannot be used with factory drum brakes, but are a direct replacement using original-style ball joints and factory steering arms. The decision to go with the 13-inch brakes will require that l1-inch (or larger) rims be used. We'll find out the final decision on the rims and all the other details on the Project '62 in upcoming issues of Rod & Custom. We've had a sneak peek into the future and we think you're really going to dip, this one. The centerpiece to this installation is the newly designed spindle. The CPP 2-inch dropped spindle can be used with any disc brake kit from the budget OEM-style brakes to the performance minded 12- and 13-inch units. A quick comparison will note how much sturdier the new dropped CPP spindle is over the factory unit next to it. After removing all the frontend components and discarding the tired old drum brakes, the reassembly begins with the cleaned A-arms receiving a fresh set of ball joints. Pressing a new set of bushings into the A-arms will eliminate the frontend slop that follows after many years of driving. An impact wrench makes installing the new control arm bushings easier, but a conventional rachet will work too. After the new dropped coil is finessed into place and the new shock is installed, the new spindle finds a home in between the new ball joints. Because of the well-planned design of the new dropped spindles, which retain all the factory geometry of the front suspension, the factory steering arms are reinstalled.  After the new aluminium hub is installed, the new caliper bracket is bolted in place on the spindle. The new dual-piston caliper completes the installation of the new components under the front of the car. Classic Performance Products' revolutionary master cylinder contains all the valving and proportioning valves inside the unit. Mated to a 9-inch vacuum booster, this pair will supply ample fluid pressure to the new brake system.
