<VV> 4-Piston Calipers - Non-Corvair

[JVHRoberts at aol.com]

For racing, lots. 
A 4 piston caliper is fixed, no sliding mounts. This makes sure everything  
stays square and doesn't move in unexpected ways. 
The body of a 4 piston caliper is FAR more rigid than the 'C' clamp of a  
single piston caliper, giving a FAR more firm pedal, and allowing the use of a  
smaller bore M/C for better mechanical advantage. 
And pad changes are a total breeze compared to most single piston calipers.  
Pull a pair of pins, leaving the caliper in place, pry the pistons back, slip 
in  the new pads, stick the pins back in. On my 300ZXTT, a pad change takes 5  
minutes per wheel, including jacking the car up and taking the wheel off! 
Downside? They cost more. That's about it.

Can  someone tell me what the advantage[s] is of a 4-piston brake caliper 
over a  1-piston caliper?
