Nissan is recalling 169,202 of the 2007 and 2008 model year Sentra because the brake master cylinder might leak fluid, according to the National Highway Traffic Safety Administration (NHTSA).

"The internal seal groove in the body of some brake master cylinders may allow for a gap in the in the groove contact areas of the seal. This may result in brake fluid slowly leading from the master cylinder into the brake booster assembly, causing the brake warning light to illuminate," NHTSA advised.

NHTSA warned that if consumers ignore the lamp, "one of the brake circuits on the vehicle may not operate as designed increasing the risk of a crash.

Nissan dealers will inspect the braking system on the Sentra when the recall begins July 23.

If brake fluid is found to be leaking, Nissan will replace the master cylinder free of charge.
