Hi there. One of the problems with brake fluid is that it is very corrosive. Overtime, the brake lines and the connections between different lines and to other brake system components can become corroded, loose and then leak. Due to the importance of the brake system integrity for safe operation of your vehicle, it is always best to have a professional mechanic complete a brake system inspection to pinpoint the source of the brake fluid leak and recommend and complete the repairs to fix this issue as soon as possible.
