I took my 89 Civic car to two mech. They told me my car is leaking
from m/c. They told me to replace right away. I talked about brake
line leaking. They jacked it up and showed me my brake line are all
fine. He said just change the m/c. My simply thought is m/c is so
small I'm thinking I can changed by myself. I believe
the leak is between m/c and power boost. is there a seal or
gasket place bewteen m/c and power boost. all I can do is just
unscrew two bolts holding a m/c from power boost. do you think
I just replace the seal or gasket rather than replace the whole
master cylinder?
