Lengthening hydroboost pushrod

[BigB]

Hi,

Searched through google and could not find an answer to this question.

I'm installing a mustang HB unit and need to cut and thread both the end of the hydroboost rod and also the original brake rod coming off the pedal.

I have a 5/16 all thread coupler and a couple of lock nuts.

The HB rod will just have the eye cut off and then threaded. The brake rod is longer and needs to be shortened before threaded.

How do I measure this to ensure that I have enough actuation of the HB without having too much length(this is one instance where too much length can be a problem ;D) that would damage the master cylinder?

Is it a case of having the brake pedal in its uppermost position and then just line them up alongside each other and then mark my cut?

Thanks.

I think so. Check out this tech article.

Thanks but I need more confirmation than "I think so"!

The article makes no mention of measuring the brake rod for length.
