Clutch pedal free play C900...

Oct 04, 2005 11 Replies

My clutch pedal in the cab seems to have more free play than actual travel. I've got reciepts in the wad that came with it for a fairly recent clutch and a rebuild kit for the slave cylinder.



Clutch action seems fine, but the bite seems low but not ecessively low. Fluid level is good.



Any thoughts


I suspect air in the line.

Now, I _really_ suspect air in the line.

You might have air in the line.

Methinks Dave (as usual) is probably correct, although bleeding the clutch is not as simple as brakes as you'll need to pressurise the brake fluid reservoir. You can get a kit from Halfords for this one. Bentley manual explains the procedure.

Good luck Al

Not if you use Dave Hinz' IV method of clutch bleeding with an elevated turkey baster connected to the slave through a plastic tube!

Bleeds "backwards".

Works great!

Thank you, I hoped to be the case. Didn't want to consider a worn pin the linkage as UK cars "Swap across" under the dash using rod. I think it is working well enough to get me to the weekend.

I have a EZ-Bleed pressure bleed kit. Got one when I swapped the calipers on my last 900.

I haven't tried that yet, but I already have a pressure bleeder that uses the spare tyre. That worked last time gave the clutch and brakes a bleed through on my last 900 after going a front caliper swap.

Wow! I never gave that much thought. That's true for the brake also, I would imagine?

Doesn't really make it much harder to fix. The master cylinder 'pin' is dead easy to replace, and the other bit (that's part of the linkage) can be welded in-situ. I did this on one of my early 900s, and it worked very well.

But definitely try bleeding it first - that's far more likely.

Yup. Pedals are on the right, UK drivers side. brake light switch, servo (or ABS accumulator), and the brake/clutch cruise switches are on the left.

I changed a servo on my last 900, bit of a pig tightening four bolts, assembling a cotter pin with washer and fitting a split pin by touch in the dark. Removed the knee bolster, and then started unbolting stuff until I got closer.

Don't worry, will try the bleed first.

The C900 is notorious for wear in the hole in the clutch pedal mechanism itself. It is common to weld the hole shut and drill a new one. Also, the pin that goes in this hole can wear as well.

My advice is to get this fixed before shifting into reverse ruins the transmission as it did on mine.

Check the clutch pedal mechanism for wear and get under the dash and see if depressing the clutch pedal has a lot of play before the hydraulic mechanism is actuated.
