Loosing Clutch Pedal pressure?

[Petronas]

What does it mean when I'm loosing clutch pedal pressure?

Are my Slave/Master clutch cylinders failing or is my clutch going?

I seem to be loosing pressure up the top of the pedal so there is a big gap between pressing the clutch and actual clutch pressure. The pressure comes back to normal every now and then.

Been like this for 2 days.

check fluid levels and for leaks

otherwise i'd be betting on the master cylinder seals

if it's fairly old it's probably time to change it
iirc new unit from honda for an ek was only about 75odd, not too sure about a bb6 though but i wouldn't imagine it'd be much different

yeah thats right, check the fluid level first, i had the same problem some time ago, my clutch was a bit softer than normal, checked fluid level, it was almost empty, topped up and gave few pumps of the pedal, all back to normal. i can't seem to find a leak but i have to top it up every 2-3 month, not a big deal, so i left it like that. but i always carry a bottle of oil and brake fluid in the boot of my car.

Do you guys know how to check fluid levels? I've never checked clutch fluid levels before

usually in a smaller reservoir next to your brake reservoir

also follow your clutch pedal upwards where it connects to the master cylinder itself, usually leaks from there too

Next to you brake booster there should be a smaller plastic reservior with a grey cap on it, open the cap and see if there are fluid in it, there is a line on it where the brake fluid should sit, anything below that needs a top up.

Thanks guys.

To eg6sir - You mean clutch fluid in your last sentence yeah?

Sorry yeah, clutch fluid, but you use brake fluid to top it up though.

Just topped up the brake and clutch fluids. (I'm guessing the bigger cap was the clutch fluid) - The clutch fluid was only 2 - 3cm below the line but filling it up made a difference, clutch was back to normal. We'll see if the pressure holds or not...

[vinnY]

bigger one = brake fluid
smaller one = clutch fluid

[Petronas]

bigger one = brake fluid
smaller one = clutch fluid

Oh... Well the clutch fluid was only about 1cm below the line... But it still made a difference... Dunno...

It's most likely your Clutch Master cylinder. Best way to check: you know where your pedels are. Get on your knees and look at your pedels. The actual floor/firewall will be wet, dirty and covered in clutch/brake fluid. It may have dripped down under your carpet or will be all caught in the carpet, and as seen on a mates car can be quite messy and can corrode the floor. It's best not to keep topping up the fluid and leaving it. If you are having to top up your Clutch fluid, then it's obviously going somewhere. Somewhere being on the floor of your car directly under your feet/pedels. It takes 2 seconds to check it out. If it's your Master Clutch Cylinder, then go to Honda get it replaced, and make sure you wash the part of your car where there is the fluid to avoid corrosion.

FYI, Brake Fluid and Clutch Fluid is the same thing. They split it up into 2 products as a marketing thing, so you buy both, expecting them to be different.
