How to adjust hydraulic clutch?

[FletchCossie]

Does anyone know how to adjust the biting point on a hydraulic clutch? My biting point is right next to the floor.

[Rolls]

surely it'll be done ony the master + slave cylinder sizes?

[andy escos]

sounds like you either need to bleed the system or adjust the push rod on the master cylinder to raise the pedal up a bit .

[FletchCossie]

The pedal is in line with the brake pedal don't wanna raise is up more cause it will be awkward to drive

[Warren]

Is it a centre push system or external cylinder with the arm ?

Only real way is to change the master/slave cylinder to a different size. There are only two sizes of slave cylinder, I found the smaller one to be be the best. Bigger the master the higher up the bite is.

from memory you can get master cylinders in...


0.625
0.7
0.75

I have the smaller of the two slave cylinders and a 0.7 master.


There could of course be another problem causing it, and that might be a wilwood master cylinder. In which case its shit and will leave you without a clutch pedal shortly

If yours is - change it now!! Just get a girling one!!


A top tip if you do have a wilwood master is to check the brake fluid and make sure it isn't silvery grey - it's all the aluminium wearing off the inside

Warren, external cylinder with the arm. It's a Reyland kit bought about a year ago .

KJC, everyone else seems to have these kits without problem. The biting point is ok, but I wanna be 100% it's disengaging the clutch as the gearbox is crunching into reverse.

[kjc300]

if its a Reyland one the sizes will be fine. Unless the pedal hasn't been drilled in the right place.


Just double check the master isn't a wilwood one, as martin had to stop using them as they had too many problems with them.

[FletchCossie]

Thanks mate, I'm sure it's drilled ok. Will have a double check on everything and re-bleed it

Thought the 2wd box does crunch into reverse as something to do with synchro

[FletchCossie]

Col, I thought that as well mate, but with the low bitin point I wanna be safe

[RWD_cossie_wil]

Fletch, 2wd T5 has no syncro on reverse, whenever you select reverse, put it into 1st first, then reverse, gets rid of the crunch as it matches the gear speeds

[FletchCossie]

Thanks Will, I have already started doing that will see how it goes with the low biting point and keep putting it in 1st first

what do these figures actually refer to??

I need to custom spec a hydraulic clutch system for my car and no one will help except with a "buy our kit" which is useless when i intend to use a focus/puma master cylinder as theres no room for a conversion kit on the bulkhead. I dont want to buy a kit to throw half away

Warren, the sizes above are the bore diameters of the cylinders.

They are imperial not metric, sorry if that was obvious.
