Differences in Pedals

[J-B Racing]

Can anyone descibe in detail the difference bewtween the Power Master Pedal in the Buicks and the Vacuum Set up Pedal??
Is it the Ratio?
is it the Shape of it.
Can someone post a pic of both Pedals side by side??

Thanks

Go to www.tomsttype.com and go to the vacuum brake link on the left.

looks like it falls exactly halfway between the vacuum hole (lower) and manual hole (upper).. so if you had a vacuum pedal and want to go with a hydraboost, you'd put the pivot in between the existing holes. if you are going from a hydraboost/Powermaster to a manual or vacuum setup, you'd have to find out how far the proper hole is away from the existing hole.. hell, you could just google "brake pedal ratios" and figure it out without too much effort..
