Clutch Master Cylinder

[RXWPN]

Hi Guys,

Can we use Evo clutch master cylinders on a facelift Legnum VR4? I have an aftermarket heavy duty clutch and the engagement point is right at the top of the pedal and adjusting the pushrod assembly doesn't seem to do much. I have heard that the Evo master cylinders have a larger bore and may make for a better engagement point? I have a new OEM spec Legnum master and slave cylinders just not happy with where it engages. I hope clutch isn't worn its only done under 30,000 ks and it isn't slipping at all.

Has anyone tried the Evo master cylinder?

Cheers

I've never heard that before. I'd be interested to hear the results.

there has been a lot of talk on here about brake master cylinder and using different size one but i have never heard of anyone wanting to change a clutch master cylinder.

is there any mechanical adjustment on the pedal side of the clutch master cylinder i have a clutch pedal and master cylinder in the shed as part of my manual conversion kit i can have a look tomorrow if you want.

I'm not 100% sure, but I think that adjusting the shaft just adjusts the free play. winding it in just makes the pedal have less travel which doesn't feel great. I think clutch just might be worn ill get it checked. I'm not going to be happy replacing one very 30k though.

make sure you are not low on clutch fluid. not sure how that would effect engagement pedal height but with checking.

Use a camera or friend to check the slave actuation compared to the pedal.
Also try making the push rod shorter. I found that trying to have it too long stopped it being able to self adjust.
