I check all my fluids every week. The trans fluid is fine as well as the oil and now the coolant and brake fluid. I've only had the car about 8 months and last week is the first time I had to add coolant and only because I think it evaorated from a small hole in the overflow tank. The car never overheats. As the brakes go I know there has to be a leak somewhere and I hope to find one today and fix it. I still can't explain why only sometimes when I drive the car hard it will spit out whiteish smoke from the tailpipe. I tried to make it happen again today but it wouldn't do it. Should this be a concern that I need to spend a lot of time and effort trying to get to the bottom of because besides the leaky brakes the car drives like a dream except for the occasional hard shift into reverse.
