I doubt that is the problem. There are other things to check first.
Starting at a rear wheel cylinder, remove the brake line and push the pedal.
If
fluid flows, the cylinder is bad. If no fluid, move forward along the line to
the
splitting block, and remove the line going in from the flex hose. If fluid
flows, the problem is in the block or the line from the block to the wheel. If
no fluid, remove the line going into the flex hose. If fluid flows, the flex
hose is bad, (That would be my guess.) if no fluid, move forward again to the
next connection.
Play Shelock Holmes and track down the problem by eliminating things
systematically. After you eliminate everything else, the last thing that is
left, no
matter how improbable, has to be the problem.
That process works with electrical problems as well. Just make sure you don'
t let all the smoke out. :-)
