Service brakes

84 reports12 crashes
“When I was driving my car with my child in it my break tightened up and I couldn’t apply them to stop I had to let my foot off the gas and let my car slow its self down safely. When I got my car home my husband looked at it and found out that my vaccum pump had went out and part of it broke off in the engine. This is very unsafe and this needs to be investigated because people can’t know when the vacuum pump is going to go bad this issue lays on gm and Chevy to make sure the parts they are using will hold up and be safe”
