I just looked at js_demo with my toe brakes and they show the same behavior, 
range is +/-1, left brake sense is reversed.

Debian Linux 2.6.38-2-686 #1 SMP Thu Apr 7 05:24:21 UTC 2011 i686 GNU/Linux

I have this as a configuration: (add an offset so the range is 0..2 then 
multiply by 0.5)

 <axis n="1">
 <desc>Left Brake</desc>
  <binding>
   <command>property-scale</command>
   <property>/controls/gear/brake-left</property>
   <offset type="double">-1.0</offset>
   <factor type="double">-0.5</factor>
  </binding>
 </axis>

 <axis n="2">
 <desc>Right Brake</desc>
  <binding>
   <command>property-scale</command>
   <property>/controls/gear/brake-right</property>
   <factor type="double">0.5</factor>
   <offset type="double">1.0</offset>
  </binding>
 </axis>

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
