History of problem, started leaking out of the top of the reservoir, I have not put any brake fluid in it and it had never leaked before. I removed the fluid in the reservoir after making sure the system was depressurized, replaced with clean fluid and was sure not to overfill. Now the electric motor runs & won't shut off. I read about a condition called air lock and tried to fix it by allowing a gravity feed from the reservoir after removing a specific line from the master cylinder. It did not fix the problem, I was never able to get any fluid to drain as gravity feed from the reservoir. The fluid is very dirty and I'm afraid the internals might be in bad shape. Everything was working great, only had the car for about 3-4 weeks. Any suggestions?
