General disc brake question

FISHBREATH said

Thanks for the input, guys. It is a '68 'Cuda, soon to have a 440 & 5 speed. I want it for street use, so it will not see a 1/4 mile or road course track, but I want it to stop like a newer car. I noticed that the aftermarket multiple piston brakes are much more expensive than single piston brakes.

How about rotor size for this application? Is bigger better for the street?

Larger rotors would offer more friction surface, theoretically allowing more braking force. Would also add more mass though, something you don't need on the front of a big block A-body. As you may know, the 440 'Cudas from the late '60s were notoriously nose-heavy and supposedly handled terribly due to the poor weight distribution.

Whatever pieces you choose for the swap, you'll want to make sure the rear brakes are in good working condition too and that the proportioning from front to back is dialed in correctly. Most of the braking is done by the front brakes, so with the added weight, it might take a little trial and error to prevent lock up. I'd consider new strut rods and bushings also (to handle more braking force) and heavier duty torsion bars with the extra weight up front.

The extra weight will also change the alignment specs, which can affect braking if incorrect.
