[DeTomaso] myth of Pantera braking force limiter?

[SOBill at aol.com]

Jim,
 
There is no myth about a brake force limiting component on a  stock Pantera.
 
There are two pressure related components of the brake system in  the front 
trunk of a stock Pantera.
 
One component  is the front/back brake pressure proportioning  valve. This 
valve is plumbed so as to reduce the pressure to the front brakes  with 
respect to the rear brakes after a certain threshold pressure is reached.  This 
pressure reduction to the front brakes, which is backwards from every other  
application of a brake proportioning valve, is so the Pantera front  brakes 
are more nearly balanced with the stopping power of the rear brakes.  The 
pressure characteristics of this valve were tested and are described at  
_http://www.panteraplace.com/page199.htm._ 
(http://www.panteraplace.com/page199.htm.)  
 
The second component mounts the brake light switch. This  component also 
contains a shuttle valve and an electrical switch. The  shuttle valve senses 
the brake line pressure of the front and rear brake  systems. If the 
pressures are grossly different due to a major pressure loss in  one system, the 
shuttle valve will move so as to close the electrical switch and  light a brake 
failure warning light on the dashboard.
 
Have fun,

I went by Steve Wilkinson's today to get a brake caliper  rebuild kits and 
he said there is no front / rear brake force limiter on a  stock Pantera. 
The square thing is just the brake warning switch and the  cylinder is a 
pulsation absorber, so if rotors are out of tolerance you don't  feel it in the 
pedal.


So if I remove the extra stock caliper on  each rear wheel I should not 
have to put a valve  in,

correct?
