Balance bar. Am I going to die?
scudderfish - 3/6/14 at 05:09 PM

I'm overhauling my brake pedal. Looking at the current setup, the pushrods are cocked, the master cylinders are wider apart than the width of the balance bar housing


Reading this document
http://www.wilwood.com/TechTip/TechPedalTip.aspx says this is a no no. However, if I move the clevises so that the pushrods are square, then they will be further away from the pedal than the 0.25" specified. Should I put some washers in there and pretend the pedal is wider than it really is? Will I go straight on at the first bend and plough into nuns bottle feeding abandoned kittens? I'd like to avoid major restructuring, but I'm toying with the idea of scraping the current pedal, cutting out part of the bulkhead and fitting one of these http://www.obpltd.com/Pedal-Boxes/Pro-Race/Floor-Mounted-Bulkhead-Fit/1-Pedal-Units-BHF/Floor-Mounted-Single-Brake-Bulkhead-Fit-Bias-Pedal-Unit-OBP004 0PR

You are supposed to have large washers between the clevis and tube

the pushrods are best set parallel, its more efficient, the design of the master cylinder allows for misalignment in all directions, because hardly any pedal set up allows the pushrod to be 90 degrees the whole time, by the nature of the pivot points the angle of the pushrod changes, but its best to have them as straight as possible in the first place

as stated above, fit the washers and at the same time get the pushrods straight. measure the distance between centres of the bolts on the bulkhead and then copy this dimension to the clevis centre points

Yes, you are definitely going to die... eventually, like the rest of us; It's the only certainty of life.

The balance bar though, isn't going to kill you, the nuns or the kittens. It's not ideal but re-spacing and fitting washers should sort it. Just be sure to leave enough lateral play for the bar to operate without binding/locking out.
