Nissan is recalling 169,202 MY 2007-2008 Sentra passenger vehicles equipped robert Bosch master cylinder. Due to the machining irregularity by the supplier, the internal seal groove in the body of some brake master cylinders may allow for a gap in the groove contact area of the seal. This may result in brake fluid slowly leaking from the master cylinder into the brake booster assembly, causing the brake warning light to illuminate.
Dealers will inspect the master cylinder/brake booster assembly and if brake fluid leakage is detected, the master cylinder will be replaced with a new one free of charge. The recall began on August 20, 2008. Owners may contact Nissan at 1-800-647-7261.
