Clifton Posted June 20, 2007 Share Posted June 20, 2007 Piston size effects the bias too. If I plan to do any hard high speed braking, I dial all the rear pressure or it wiggles alot when you hit it, I know it is a wiggle away from getting ugly. Around town/low speed, I add almost all of it without rear lockup. My rears wheels/tires are wider than the fronts too. I am also running the stock proportioning valve after the adj one. Don't know if that makes a difference. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted June 20, 2007 Share Posted June 20, 2007 I am also running the stock proportioning valve after the adj one. Don't know if that makes a difference. This is also a bad idea. The stock and aftermarket proportioning valves both have a "knee" where the pressure reducing effect increases. Having two of them in series basically means that the harder you step on the brakes, the less the rear brakes actually do. More info at the link below: http://www.stoptech.com/tech_info/wp_proportioning_valves.shtml You guys should both do a dual master setup.

tonycharger72 Posted June 21, 2007 Author Share Posted June 21, 2007 Thanks for the link mate, will look into it, For rego I wasnt allowed to have an adjustable bias for the brakes, so I had to cut the top of the adjusting valve, so have had very little pressure to the rear brakes since doing the conversion - mix this with my tracking issues and the car isnt a whole lotta fun in the wet!!! Problem is so many little issues to take care of before I can deal with the brakes, steering, suspension, engine placement, radiator shroud, heater needs replacing, etc, etc, etc , Quote Link to comment Share on other sites More sharing options...
