Default Clutch a bit floppy at the top

Seems a number of elements of my car are choosing the post-Christmas cash depletion to rear their heads. Leaky lights, dodgy brakes and now this...

The clutch pedal has very little resistance for perhaps a little over half its travel, and even with the pedal fully depressed, slotting a gear requires a little more force it seems.I checked around the pedal and carpet for any signs of a leaky master cylinder, but seems dry, and the reservoir seems full in any case...Any other suggestions?

Mine gets the same symptoms with no obvious leaks, I just bleed it up every other year.

Straight forward to do on the drive/road and you can gravity bleed it if your on your own.

I'll try that first, thanks.

Can you recommend a fluid?

I cant recall which DOT rating you need but if you check the cap it may be DOT 4/5.


Heres the link for the gravity DIY

Any DOT 4 brake fluid will do.
bleed full system
check clutch pedal height (as per workshop manual)
check there is zero free play in the pedal.
remove slave and grease the ball/cup, also remove any "nipple" on the ball end of the slave.

Refit everything and you should notice a difference

Honda spec is DOT3 for the hydraulics ( you don't want to be using DOT 5 as that is silicone based ) probably good idea for the clutch as it's less hygroscopic than DOT 4 or 5.1 and you're not going to be cooking it hot like you might with the brakes.

A slave cylinder clean might be a good idea if the bleed doesn't help, the amount of grey mung that came out of mine was considerable.

curse loudly when you realise the piston has popped out of the cylinder and is now caked with driveway dirt
