Were the original bolts used rounded on the end? When I get to where I have 1 3/4 pedal travel, the new bolt I put in digs into the cam fairly hard. I can get it to work and I put some grease on it but perhaps that bolt needs a chamfer or radius on the end. Thoughts?

Turn the bolt upside down and let the head go towards the cam - then the load is spread out on more area :-)

If there are raised markings on the head of the bolt, file them off first and polish the bolt head to make it smooth, then install it upside down as Roger suggests. Keeping grease on the cam wearing surface is a good idea, too. :-)

Second both Roger's & Marks comments.

I slightly radius the bolt head, polish and grease.

You could radius the end of the bolt, as it get worn to that shape anyway.



Worn bolt on left.


Or as posted, turn in a new bolt upside down, using a new bolt with hex ground off some, to provide a smoother glide.

why not use a carriage bolt?

Carriage bolts are coarse thread.

The cam is tapped for 3/8 NF.

I ground the markings off as described, put a 1/8 Rad/Chmf on the hex and put it in. It made a total difference. With these improvements and a little greased it works smooth as greased catshit on a door knob.

One thing I do is try to remember to push the low peddle in before setting the hand brake with the same setup.
