I lost all my breaks so i put break fluid in will that hurt my car?

Hello, your brake system is a serious safety system, and should never fail to the point where you "lost your brakes". I urge you to have your brake system checked immediately before driving again to protect yourself and the safety of others. If your brake system needed brake fluid to stop again, there must be a serious leak that requires immediate attention. Having the system function again after adding fluid indicates a major safety issue. No failure of brake operation that was corrected by adding fluid is acceptable to ignore. Seek professional guidance immediately. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
