SOURCE: service brake booster display

Your brake booster is the heart of your power brakes. It runs off a vacuum from the intake to booster. Your brakes will still work as long as they have fluid. They'll just get stiff. It probably means you need a new one

Battery not charging/ service brake booster is on after getting off work


Do a diagnostic test to find out what codes come up. Once the repairs are made to clear the codes, you shouldn't have any more check engine lights cycling.

Flashing battery light and brake light


Are you referring to warning lights on the dash board? The flashing battery light may mean you have a charging problem and the flashing brake light may mean you need break fluid or have an other brake issue. Take it to a service station or the dealer. Or read the owners manual.

Battery not charging/service brake booster


The brake booster uses vacuum from the engine to multiply the force that your foot applies to the master cylinder.

After we jump my car and take the cables off we touch the brakes and it shuts off. Why?


Your alternator is not charging or the battery is faulty. The load of the brake lights is draining the battery of the minimum charge needed to keep the engines computer running properly. If you turn on another high drain electrical item, like high beam head lights it will do the same.

Another possibility is a faulty power brake booster; applying the brakes would cause a loss of engine vacuum if the booster were faulty-this is far less likely..but possible.

Chevy Suburban 1500 -- Battery Not Charging Light....Replaced Alternator....Still had battery not charging light....Replaced battery....Still have battery not charging light...also first time seen service...


Make sure that you buy a 'lifetime' warranted alternator from your parts source to avoid problems with bad alternators out of the box. I would try to return and exchange the alternator with one that tests out ok on a bench, in order to verify if the wiring in between the alternator or the alternator itself was bad.

Service brake booster would have to do with the vacuum or power booster problem around the master cylinder for the braking system. That wouldn't have anything to do with the alternator, I do not believe.

Good luck on these repairs.
