clutch cylinder problems

91 Accord EX-R 285,000kms

Got some intermittant clutch actuation troubles, any ideas on
differentiating between a master or slave cylinder internal leak?

Or is it a parts swapping exercise? Factory manual is no help is diagnosis.

Thanks,
Steve

Pull back the rubber boots on both of the cylinders. You should be able to
see any fluid leaks. Note that you'll have to go under the dash for the
clutch master cylinder.

diagnosis.

With the age of the vehicle, and the kilometers....I wouldn't
just replace one or the other. Replace both of them as
a unit. Far less likely to have problems if you do this.
Of course, you need to determine that the problem is
hydraulic related first.

Hi Stephen,

If your Accord is like my '94 Del Sol, there is no such thing as an
"internal" leak on the clutch system -- no shaft seals to contain any fluid
leaking past the piston seals. If you have a fluid leak, look for it under
the dash for the master and peel back the boot to check the slave.

I did have an intermittent problem with the clutch on my car --
unpredictable clutch pedal travel prior to engagement and synchro's working
hard occasionally to get the disk to slow down enough on gear changes.
Turned out to be a small piece of metal broken off of the disk bouncing
around between the disk and pressure plate. Had to pull everything apart to
figure it out though.

Good luck finding your problem -- hopefully in the hydraulics, but don't
ignore the rest of the system.

Look for bubbled paint on the firewall or booster where the MC mounts.
As another noted, you are way ahead to just change both and be done with it.

Found bubbled paint at the firewall, just a minor leak, just enough to
inhale a little air to bugger things up. A new dealer master ($108CDN) and
all is well.
