I've been through my brakes a million times and I'm still not satisfied with the pedal height. I'm 99% sure everything is correct except the MC push rod. It feels like I have a good 1" of pedal travel before it touches the MC.
Anyone have an idea what the proper clearance procedure is? -Aaron |

The pushrod attached to the pedal is adjustable. There is a lock nut you loosen and then twist the rod to length/shorten it.

Thanks! Just didn't know what the value was. I'll check that it's 1mm.

You're gonna have to get down there and feel the play with the ol' Mk1 fingertips.

Yeah... I'll try shoving my fingers through the AL board I have first and see if it's close or not. If I could get that free play at the top of the pedal down a bit I'd be happier...

If'n ya pay real close attention, you can push the pedal and feel the pushrod hit the MC plunger/piston. 1mm at the pushrod doesn't equal 1mm at the pedal, but you can make an approximation in your head.

*Assuming* it's a 1.25mm thread pitch I could also run it in until it just touches and then back it off one turn.
