NHTSA recall 01V197000

What's wrong: Due to an assembly error, one or both self-locking nuts that secure the pedal assembly to the booster may have been cross-threaded on the booster studs that protrude through the firewall. In such a case, the nut(s) would not be fully seated on the stud(s).

Why it matters: If this occurred, the effective brake pedal travel could be reduced due to relative movement between the pedal and booster. Braking performance while driving could be adversely affected. In addition, it is possible that the booster could develop a leak after an extended period of time resulting in…

The fix: Dealers will inspect the two lock nuts to determine if they are properly seated. If the nuts are not properly seated or are cross-threaded, the brake booster will be replaced. Owner notification began August 17, 2001.
