This could cause a crash. Always use the proper brake fluid. Disc brake pads have built-in wear indicators that make a high-pitchedwarning sound whenthe brake pads are worn and new pads are needed. Thesound may come and go or be heard all the time your vehicle ismoving (except when you are pushing on the brake pedalfirmly). Notice: Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, your in brake system can damage brake system parts so badly that they'll have to be replaced. Don't let someone put in the wrong kind of fluid. 0 The brakewear warning sound means that soon to your brakes won't work well. That could lead an accident.
