New for the 1959, 1960, 1961, 1962, 1963, 1964 Impala is a 13 inch front disc brake kit featuring Wilwood 6 piston calipers, poly matrix pads, Global West billet aluminum hubs, bell hats, Wilwood rotors, ARP studs, braided steel line, bearing, seals, and hardware.
The kit is a direct bolt on. No modifications are required to the spindle. However, you will need at least a 17-inch or larger rim in order to clear the assembly, and the hub assembly will move the wheel outward by 3/8 of an inch. In most cases, this should not be a problem, but you should include this measurement if you are ordering wheels.Tech Tips:
How you should run your brake lines
- If you are going to use a manual brake system, Global West would recommend using a 7/8 master cylinder. A 7/8 will provide a soft pedal and plenty of line pressure at the wheels.
- If you are using a vacuum power brake unit, a 1-1/8 master should be used.
- Global West would install an adjustable proportioning valve in the rear line and a 2 pound residual valve if you are using a drum brake rear. If you are going to run disc brakes in the rear, then the 2 pound residual valve will not be required.
For the front brakes – run the line out of the master cylinder and go to a tee. From the tee, split the lines off to the front brakes. If you have the adjustable proportioning valve (w260-11179) that has the tee built into it, run the front brake line to the valve and then the two lines from the valve, out to the front brakes.
The rear line should run out of the master to the proportioning valve, then from the valve to the residual valve and to the rear brakes. The residual valve is used only with drum brakes. If you are using rear discs, you will not need the residual valve.
