Vacuum Pump

Today I tested my $65 Chinese vacuum pump. Not so impressive. It does not turn itself off when it reaches a preset vacuum like the seller said. And it only pulls 13.5" HG of vacuum. Is that enough vacuum for the brakes? Am I going to have to purchase a vacuum switch so the pump automatically turns off? Maybe I will try to hook it up to the brake light switch so it turns on whenever the brakes are applied. I guess this is something I can start testing already.

Oh hate.
