There are fairly simple solutions to the problem of vacuum assisted brakes. In our Metro, adding an auxiliary vacuum canister/reservoir was enough of a solution. I can press the brake pedal multiple times without losing assist, which is more than enough for this car. It's never an issue.

With this Caprice, which has bigger brakes, more inertia, and can coast much farther than the Metro, an auxiliary vacuum reservoir wasn't enough. I ended up installing an electric vacuum pump from a VW diesel (with a vacuum-activated switch) that would "recharge" the brakes as necessary when the engine was off. The Caprice could coast indefinitely and never run out of brake assist.

Other features you'll need to do EOC successfully:
  • A kill switch (you don't want to use your keyed ignition switch to shut off the engine);
  • a manual transmission (for bump starting);
  • manual steering (for obvious reasons!);
  • a deep cycle battery (EOC will ruin a standard lead-acid starting battery pretty quickly); and
  • an electric pump for the heater core coolant circuit (if you like having consistent heat in the winter!).

I looked around for it online after your first post, but didn't find anything. This would explain why! Please do let us know when it's out.
