Hello. I have a 88 GXL (have had it almost 12 years) and i recently got her started after a few month parked at my brothers house. She started right up but i noticed that the brake went completely to the floor. i pumped it a few times and it still didn't hold any pressure. I braved driving it around the block a few times and it stops but it doesn't engage the breaks until almost fully depressed to the ground. There is plenty of break fluid and the break lines have been bled. Would this be my master cylinder by chance causing this? Maybe the Break Booster? Can anyone recommend someplace to purchase these at a decent price? Ebay can be a little iffy when purchasing any car parts but that seems to be the cheapest outlet for parts. I know you get what you pay for but i know some parts don't matter too much weather they are official mazda part or not.

Another post kinda covered this too but my coolant leaks bad out of the overflow tank, it basically sprays out of it, i replaced the hoses and the caps and bleeder plug too. Is there a 'how too' on properly bleeding the coolant system?

Thanks for any help you can give me. This car is sentimental and its becoming a project car for my son and I. I have a few plans for it and it needs lots of love but first things first and thats getting it safe to drive on the road again.

Thanks again
