Hydraulic clutch

Post by DAReese » Sat Jul 16, 2016 10:13 am

Trying to decide whether to go hydraulic after the firewall gave way and I've gone through five clutch cables in a year.

How hard is the conversion? I'm guessing I'd have to collect the parts from a turbo coupe and get after market pedals from somewhere.

I've only found two people who have done it. Is it really that hard?

Another option is to Panel Bond a metal panel to the broken area. It's stronger than welding due to surface area contact. Just FYI.

Thought about that, at least adding a patch but cable keeps pulling through although that might possibly be made worse by flexing firewall. Thoughts anyone?

I've got the firewall on my parts car, and I can get one form a pull apart, so I could sandwich them on both sides on the firewall.

It's worth it. Burton power sells a pedal box modified with a hydraulic slave. It may be on an exchange basis. Having done a setup with an aftermarket pedal assembly, and seen the amount of work a friend of mine did with an aftermarket setup, I would go with the burton power.

If you are using a turbocoupe slave, you need some -3 adapters available from Summit and a 3/4" master.

That being said, you should address your firewall issues first. By going hydraulic you're not replacing any force, just displacing it.
