power brakes

Step 30:  Install power brake vacuum pump.  Without any vacuum one could sufficiently stop, but holding the car on a hill would get old quickly.  A purpose built electric vacuum pump and reservoir from an electric vehicle supply house is added to help out.

A bracket to hold the reservoir is fabricated, you may recognize it bolted to the top of the motor in step 5.

It fits in front of the battery.  The reservoir takes a few seconds to pump up after every application of the brake pedal.  It works really well!  Power brakes really improve the driving experience.
