Brake booster is the very important part of the vehicle and if there is any repair in it the total brake system may collapse. So it is not advisory to troubleshoot a brake booster.

Brake boosters don't operate with fire, so they don't misfire. Brake boosters operate on vacuum from the engine. Your vehicle may be misfiring because of a vacuum leak. The best solution is to inspect all of the vacuum lines on your vehicle and replace any lines that are damaged or look old.

Brake boosters don't misfire. The booster is a vacuum power brake assist that makes it easier for the driver to press the brakes. A misfire typically refers to an engine. It is what occurs when the timing is off or something cause a cylinder to "fire" or combust at the wrong time.

If your brake booster seems to keep mis-firing then you will need to get under the car. Once under the car you can understand why this seems to keep happening.
