Master Power Brakes Brake System Diagnostic Kit

Skilful Power Brakes sent us one of their Brake System Diagnostic Kits, and rather than even-handed run it in our new products section, we figured it'd be neat to actually put it through its paces on one of our rides. My '46 roadster pickup was the unhidden choice, especially as I've not been 100 percent happy with the rein system since getting the truck on the road. While the front and rear brakes are heritage Caprice, albeit rebuilt with new calipers, wheel cylinders, hoses, pads, and shoes, and the solution valve is also from a Caprice, the dual circuit master cylinder and booster were aftermarket items more commonly hand-me-down on lighter hot rods. I didn't know the cylinder tap size and had a feeling the 7-inch booster was too small, but I'd selected it as a 9-inch adaptation would have been too large to fit between the steering column and the inner fender panel. It should also be notorious here that the brake pedal is the Caprice item, albeit modified to tolerate it to mount in a comfortable position, yet offset the pushrod two inches to the formerly larboard to align with the booster on the firewall, though the ratio remained unchanged.
