Does anyone have the correct measurements for a 71-73 Mustang auto trans brake pedal for a car that has power assist brakes?
I'm after the measurements for the distance from the centre of the top pivot point to the centre of the pin that connects to the booster push rod.
Most information suggest that boosted brakes need a leverage ratio of 4:1. However, when I marked where the new pin needs to go on my non power assist pedal the distance works out to be 3:1.
I calculate that the pin needs to be approx 120mm or 4.724 inches centre to centre.
Here is a picture of my manual pedal.
Here is a picture of the pin area. Note the scratches in the pedal at about the 120mm mark. This is where I think the pin needs to go.
When I compare this to a picture I found on the Cougarparts web page, it looks about correct.
If any one has the measurements, I would appreciate it.
I have also emailed Cougar Parts to see if they can measure it for me.
If I was in the US I would just buy a second hand pedal. However, the cost of postage to Australia is more than the value of the pedal. So I may as well just modify the one I have.
