My little forum on timing belt replacement
A brake light that goes on when the parking brake is disengaged indicates that your brake fluid level is too low. You will not miss the distinctive smell of brake fluid if a leak is present; likewise, have your brake fluid level checked if the fluid leaking underneath your car has a light amber color. Rotor surface issues cause vibrations of the brake pedal or wheel. Brakes that need repair may squeal until you come to a full stop or when you release the brake pedal. That means that your brake wear indicators may be scraping against the rotors.
