Hi, don't take a chance with the brakes. it really doesn't matter how fast you can go,but if you get up to speed and you can not stop it doesn't matter how fast you were going. the brake master cylinder on any car must not leak fluid from anywhere. the cyl. that you mentioned is passing fluid around the seals and it should be replaced. the tii master will fit but the lines will have to be pushed into new position to reach. when you buy the new master cylinder make sure that you also get the rubber gromets to adapt the lines to the over sized openings. i have all this stuff on the shelf if you want it. good luck, e-mail me with your results or if you want parts. stone stone racing co phila pa 215.592.0265
