once, and only once because i never went back, car quest tried to sell me on a 200 brake master with a 1 1/8" bore as a comparable swap for a clutch master. his reasoning was "its the same bore, it will work fine" its not just the bore thats different, its also the stroke length. i called the guy a dumba$$ to his face and walked out. not saying this is the problem, but its something to watch out for. the 200 and 300 brake master has the same bore as a clutch master, but its different in the stroke length. they wont swap.
