Ok I take my 1999 Cadillac Escalade EVERY 3000 miles to get the oil changed and the man who changed my oil said that my back brake tank was very low on fluid. Needless to say me being a female I went and filled the tank with fluid and now my brake light is on and my brakes go to the floor. I also see some heavy spots by my back driver side wheel on the ground. What did I do?

 

changing oil every 3,000 mile is a waste and needless .. you should change oil when the computer advises you to change it.

as to the brakes, hard to tell what is happening but the car needs a visit to a brake shop or the dealer, in a tow truck.

It turns out that I needed a brake line on the drivers side front to back $200.00 bucks shelled out but hey I would rather stop than be sorry!
