Have a 2007 with manual transmission and just did the CDV (ClutchDelayValve) delete. Went with SS braided line from MC to bracket on transmission where it attaches to stock hard tubing to Slave. I followed to the letter the guidelines in this forum from other threads, using parts as done, and specified, by other contributing members..

It went as advertised, and true...there is a much more positive feel as to where the clutch bites, and better control, feeling more like a cable operation.

.....however, what I don't like is the sensation of vibration I get thru the pedal at 3K or 4K rpms. This translates to shifting into 3rd and 4th. Is almost like a tingle on the foot when depressing clutch pedal for those gears.. The SS braided line is not touching anything, or close. Is 18 inches and goes in the air from MC straight to bracket so is not rattling against anything.

I wonder if others, having done this mode, felt same thing but didn't care.

I wonder if it is vibration from engine transmitted thru the SS braided line or thru the fluid from the clutch itself.

I even wonder if the CDV is to damp this 'vibration' feel, at the expense of vagueness, instead of 'delaying' clutch action to safeguard the driveline from driver error, as commonly believed. Honda calls it a "Damper"

Thanks from any opinion on this matter.

 

Mine doesn't do this. Could be your throwout bearing.

 

This mod WON'T cause this issue....

 

My clutch is shot and has chatter on engagement. I still feel nothing through the pedal with the CDV removed.

 

Thanks, but it was not doing it before I removed the damper.(CDV), or at least did not feel anything like that.

Thanks everybody. Appreciate your answers. Apparently is just me, or my car. Am just trying to find if there is any other reason before installing back the CDV. I'd rather have the vagueness, but not the feel of vibration.

Hi OP,

Can you share your parts list please? I am having trouble with the other CDV posts since they are too old and the parts link don't work.

 

You only need to get the EM2 (2001 civic) clutch master cylinder and maybe a drill with a ½" drill to enlarge the 2 holes....

 

My is a first generation 2007, thus did not need a different master cylinder, just deleted the CDV mounted on fender, however, I believe the semi rigid steel braided line connected directly from Master Cylinder to engine bracket and Slave, transmits the tingles from engine at high RPMs which I don't care for. But it is true the Clutch feel is more positive, sportier, and more fun to drive.

Below is a picture of parts I used, however, am planning on going back to original hard line from Master Cylinder, and then use a DORMAN H381618 for Honda Civic 2005 to connect Master hard line to engine bracket and and hard line to Slave. This is m12 x 1 female to M10 x 1 female, rubber 'braided", and believe will eliminate or reduce the tingles. I will have to fabricate my own bracket for the fender, and I will be using the Honda clips, as in the engine bracket on Slave Cylinder to fasten the line to said fender bracket. Thus basically will have about same setup as factory, minus the CDV.
