Sorry about the confusing terms. I'm talking about the clutch hydraulic
system. If you replace the master, you WILL have to bleed the slave as it
will not release the clutch after about a thousand miles. I think a lot of
people think the clutch slave has failed at that point, and they replace it.
In replacing it, they bleed it, of course, which was--unbeknownst to
them--the original problem.
My point is that if you have replaced the master and the slave seems to have
failed, bleed it first before you spend the money and take the time to
replace the slave.
