It's hard to comment on reliability since everything depends on the maintenance it got from the previous owner(s).
Fix the brake fluid thing first. Jack it up and remove the wheel where the leak situates and investigate the situation. The brake system is not complicated, check the lines and connectors, maybe the connector just got loose?
