What can fail
A soft coating inside the master cylinder wears down a rubber seal prematurely, causing brake fluid to leak internally. This reduces your braking power when you press and hold the brake pedal.
What the fix does
Dealers will inspect your master cylinder and replace it along with the brake fluid reservoir. They'll also clean certain brake lines. Service is free.
