Ok, I have a 95 monty LS with about 149K. About 2 weeks ago my brake light came on so i checked the fluid and it was low. I added some Dot 3 and the liht went off. Well, its been about 2 weeks or a little less and the light just came back on. I again checked the fluid and it appeard to be a little low so i added a little more. The light didnt go off this time. As far as the way the car is braking, everything seems normal like always. Where should i go from here? Thanks
