So, I live at 7800 feet and my idle vacuum is around 12 to 14in hg.
This causes my brakes to be somewhat to be desired.
I added a vacuum pump and switch to the brake booster which puts about 20 in hg into my vacuum booster.

This helps alot....the ex will stop faster with much less pedal effort.

The question I have is my vacuum readings change on the gauge I put on the brake booster vacuum side. When cold the pump will shut off at around 20 in hg, and the pump will run for about 5 minutes to get to 20 in hg. Once warm the pump will draw down the system to 20 in hg in about 30 seconds. And left to sit in a warm engine compartment with engine off the vacuum reading increases from 20 in hg to 25 in hg. Is this normal?

Guess I should look into a hydro unit.....does anyone know of a kit for a 2000 Ex?
