2007-12-05ALERT! Before you replace your suspected failing brake booster you might want to change the o-ring seal between the master cylinder and booster first.

If your engine is producing good vacuum to the booster but your brake pedal still feels hard then at least check this o-ring.

You have asked for it so we decided to deliver. Here is my recommendation for the best vacuum test pump you can buy for the money. Over the years Ive used three different types of vacuum hand pump testers and out of these three this one has proven to be the best all around. It has the best feel of the grip when pumping, the greatest amount of vacuum created at each pump stroke and the highest durability. This unit has a brass body and is very well built. Must better than the Mighty Vac plastic units.

Use this on your diesel to test for vacuum pump operation and to isolate major problem areas. Use this on your gas engine to check for intake leaks, valve timing problems, ignition timing, and fuel injection problems. Can also test low pressure fuel pumps. Gauge reads to 28 inch Hg Vacuum and 0-10 psig pressure.

Others may be full of vacuum leaks due to heat and age.
