For Sale May be a world record for an NYB

What is the difference? Is it smoother than Smoooooth ?

More effective, the brakes really are stronger feeling. Of course Mr C had the Imperials pretty well worked out prior to my driving. Eddie had the NYB fronts in full working order, I don't remember if he did anything with the back... those wheels haven't come off yet, but the park brake cables are good.

Now if you are going down a step hill and stall... I recall from my first Imp that the brakes didn't want to stop with both feet and a big pucker in the seat... I grew up on a very steep street.

Drum brakes are 'self-energizing' (which has to do with the geometry of the brake pivots and physics of friction and reaction forces) and with all else equal, would provide a little more braking in a no-vacuum-boost situation. Does the 4-wheel disc Imp use a different MC or booster, I wonder? Would seem logical to have a higher-boost booster there, which would then require more leg effort if no boost.

Not that I am aware of... but there is a lot about Formals I am not aware of yet... Maybe a more knowledgeable member will chime in. The master reservoirs are different, but I think piston sizes are the same.

Self energized is because there is no second anchor point, all the shoes adjuster all rotate to locate on the top anchor pin via the rear shoe iron this is why the rear shoe is the bigger, it does a larger % of the work. On let's say a big truck they have a anchor point and a s cam side that actuates the brakes like the wheel cylinder, the S cam turns but is not supposed to have any axial movement and will cause that wheel to lock by helping to self energize, this is why you see a truck/trailer sliding a wheel and not even stopping fast.
