Searched for this topic briefly, didn't find anything. So I took my 01 yukon to the shop to get an oil change (I'd rather do it myself but I'm now in Grad school and have no tools at my new apt.) and my brakes have been kind of pumping when I am coming to a stop. Not a lot but you can tell just a little bit. Can't feel it at all until about 7 mph or less. Guy at the shop came back and said my brake fluid needs to be flushed. How much would yall assume that would cost? What's the effects if I don't do it for a while longer? Tight budget (fully living off of loans) and don't want to do something too early that isn't really too bad.
