I have a 1989 Toyota Corolla and have noticed a leak by the passenger front wheel?

Can I safely drive my vehicle if the wheel cylinder on the front passenger side wheel has leaked?? I can't afford to have my brakes done yet.I have a 1989 Toyota Corolla and have noticed a leak by the passenger front wheel?it would not be a cylinder would be a caliper or brake hose,and no you shouldnt drive it brake pressure can make it leak worse or fail
