Default ls240 clutch engagement issues.

I have the wilwood 3/4 master cylinder that is mounted using a 1/8" metal plate to utilize stock mounting studs.

Clutch has been bled several times and the rod on the master cylinder is extended as far as the oem bracket will allow.

It seems that the pedal is in the correct position, and feels nice and stiff.


any suggestions as to why the clutch still will not engage?

how much free play do you have in the pedal till it starts engaging?

ive heard some people have had to make a new bracket for the pedal. mine is all the way out and it engages about 2 inches off the floor.

no you typed it fine, sounds like you need to make a new pedal bracket for your master.

I had a similar problem after I replaced my flywheel. The car would start in neutral but I couldn't get the clutch to disengage...just grinding. I thought it was a hydraulics problem but in the end it turned out to be the ARP flywheel bolts that I used - the heads on the ARP bolts were too tall, and were interfering with the springs on the clutch disk. I replaced the ARP flywheel bolts with stock bolts and I was good to go!

Fidanza aluminum flywheel and Centerforce Dual Friction 12" clutch.

After finding the issue, I tested the bolt length on my bench with the Fidanza and the Centerforce, then the Centerforce with a Centerforce steel flywheel. The ARP bolts were too tall no matter which flywheel I tried, stock bolt heads are much shorter than the ARP ones.
