1993 Chrysler town and country


#1

I am having a problem finding the name of the part i need for the van. I have the fully loaded town and country and the brake system had what sounded like a pump running. Now the noise went away and the brakes do not work. I need to find out what that bulb by the master cylinder is and what it does.

That is the brake booster, and it uses vacuum from the engine to boost your pedal pressure for power brakes. If it was leaking, it should have sounded like a large sucking sound. If it fails, you’d have to press extra hard, maybe with both feet. to get the van to stop.

This is a pain to replace. You’d have to remove the master brake cylinder, then unbolt and disconnect the booster from underneath the dashboard. Most are not easy to get to.
