Pedal travel with HTOB
I'm over here in the UK on vacation and I got to thinking about my clutch pedal travel. The pedal travels all the way to the floor which is also the full stoke of the master cylinder. I noticed that the clutch begins to engage at about the half way mark of the pedal travel as I release it. Should I think about installing a pedal stop to reduce the amount of movement as it is quite a stretch to put the pedal all the way to the floor.

Yes, a pedal stop would be an excellent idea. In some cases a stop is necessary to keep the slave from hyper-extending and consequently damaging its seals.

Re: Pedal travel with HTOB
Came up with an interesting pedal travel stop. I removed the clutch master cylinder and tapped the bottom hole with a 3/8" coarse tap. Then I reinstalled the cylinder using a hex head bolt on the inside of the pedal box with a locknut. by adjusting the "stick out" of the bolt I can restrict the pedal travel. The bolt head works against the upper part of the pedal above the pivot point. A little adjustment goes a long way because of the pedal ratio.

Be careful that you don't punch through the pedal box and break the ears off of your master cyl.
There's a huge amount of leverage there. |

Fred,
I hear you but I have a jam nut up against the pedal box wall. I would have to completely distort the wall to risk fracturing the flange. |
