If you drive a certain Nissan, you'll want to hear this.

Nissan says a potential problem with its brakes is prompting a recall.

Nissan is recalling about 170,000 of its Sentra sedans because of a brake cylinder problem. The company says the cylinders in the 2007-2008 models could leak fluid.

If this happens and it's not fixed, it could increase your risk of a crash.

Nissan is notifying car owners about the recall. It will replace the cylinder for free.
