Re: [DML] Rear Calipers on Ebay



It makes a big difference.  Hydraulic brakes work by pushing fluid
from the master cylinder to the slave cylinders in the calipers.  The
slave cylinders in the calipers are the insides of the pistons.  If you 
change the volume of the fluid being pushed at the M/C and/or the size
of the pistons in the calipers, you will change the forces being applied
to the pads and therefore your braking feel and efficiency.  Most 
M/Cs these days don't use an external proportioning valve, so if 
you make the rear pistons smaller, all else being equal, you will 
apply more force to the brakes at the rear.  This will tend to 
cause the rear of the car to be unstable under braking, which is 
just what you don't want with a rear engined car.  

>From the description of the way your car brakes, I would say that
the Saab M/C is biased more to the rear than the OEM DeLorean
unit.  This bias pushes more fluid to the rears, causing them to lock 
sooner, causing the tendency to spin.
