Paul, thanks for your post, but rear cylinders need to be much smaller, because front calipers require hundreds of psi more than drum brakes.

When that kind of pressure is applied (usually from a power booster), the rear drum brakes lock up before the fronts can do their job.

The solution is a combination proportioning/metering valve which is installed on ALL disk/drum systems regardless of brand.

You have the right idea, but front brakes do about 80% of the braking. Even with drum/drum systems, the rear brake shoe area is always smaller and so are the piston diameters. We don't want the rear-end to lock up and swing around to the front.

Can you cite a company who offers disk brakes for my '55 without changing spindles? You mentioned, 'suppliers'. Who are they? - Dave
