Vehicle: Infiniti G37 coupe 2008

Diagnosis: Some times I hear whistling coming from left part and brakes gets hard

  • Is it normal to change the brake servo at 51,500 miles?
  • What is the possibility to repair it instead of changing it?
  • Should change all related parts with it? or just the servo it self?

A whistling sound implies an air or vacuum leak. With the break servo it will be a vacuum leak. A servo failure at < 100,000 miles seems quite unusual. Be sure to check that the leak is from the servo and not from the vacuum hose serving it. I'm much more suspicious of the hose than of the servo unit.
