Finally got pretty all the fab work done on the rear brakes, oops I mean brake.
Bring on the safety warnings...
I have eliminated all the drum brake components, the drums, the backing plates, the cylinders, the mounts. At the wheels there is nothing but the bearings. My guess is 50lbs less with the pinion disk brake. The brake disk itself is from a early geo metro, the caliper Wilwood just like I have on the front. Parking brake is the Wilwood manual disc caliper. I still need to confirm the midget brake cable will work and fab a mount for it or another cable.
The rear brakes only do 33% of braking, so really a third disk brake like the fronts is the right proportion. The issue besides the disk spinning 4 times faster than the wheel, is the braking will tend to lift the right rear wheel, as accelerating tends to lift the left rear wheel. I don't see it as an issue, but will see how it goes when its one the road.
