Nissan Technical Advisor 9/9/2010I highly recommend to check again the leaking issue with other workshops.
You can use the “Find a Shop” feature of AutoMD for shops nearest you.
Bender 2/14/2011Since i dont really trust the stealership, ill check it again myself, good thing i have this link to share
deanb 2/14/2011On vehicles using vacuum assist brakes, if the rear seal(s) on the master cylinder are leaking/defective the result can be brake fluid loss through the brake booster vacuum. Although uncommon, no leaks will be noticed as the brake fluid is sipped out via the booster vacuum source and burned via the intake and out the exhaust. A quality shop should have checked this for you.
