I was recently looking at the Avanti brake booster brackets, and associated toggle mechanism. It is similar to an early '60's Chevy.
What was the purpose of this, other than perhaps to give the motor some clearance?
My problem is it is mechanically disadvantaged. It appears that the pedal effort is reduced by about half, and the travel doubled to the booster. It can't be a disc brake reason, the Chevy's have drums.
Is this someway of utilizing the same pedal as standard brakes, with it's strong mechanical advantage, and not have to redo the swing pedal setup?
Just curious as to why you would go to mechanic disadvantage, only to boost it.
In just a few years, GM went to direct booster actuation without the toggle, just angled everything outside the firewall up.
1963 Studebaker Avanti: C4 Corvette narrowed front/rear suspension, C5 13" calipers/rotors adapted to C4, Viper differential with Intrax 3.54 ratio (the snake has been charmed!), coil overs, stainless tubular frame, stainless chambered side exhaust, real magnesium wheels.
Here are two links for some pictures and information.
