Re: Disk Brake

No. The front pads are larger than the rear since most of the
braking action is required in the front.

I'm not sure, but I think the front calipers need more hydraulic pressure
for the reason mentioned above. I know that for front-disc/rear-drum
systems this is the case since the drums tend to lock quickly if the force
applied is the same as for the front. Most cars have a brake
"proportioning" valve to keep an optimum balance between the different
hydraulic "circuits". (Others can add to or correct me if I'm wrong.)
