Altering proportioning valve set screw
 

I found this post by Dave Bell regarding replacing the set screw in the prop. valve to essentially turn it into a VW "T." Does anyone have any more specifics? Im interested in what bolt to buy, which on to replace (exactly) and if you need to bleed your system after this alteration:

"Stock proportioning valve is nothing more than a big spring that your leg is compressing.

Normally you can hear a faint click in the factory proportioning
valve at the knee of the pressure curve. You can change the knee of the curve by adjusting the set screw in the valve. The set
screw is pretty short which limits the range of adjustment. You can remove the factory set screw and replaced it with a longer bolt and turn it in so far that you never get to the knee, never proportion.....

Total cost.... a new metric bolt."


-Thanks!

the 'T' cost 5 bucks new,

why mess with the stock valve??

I thought this might be easier since you don't have to fiddle with unscrewing possibly stuck brake lines and rebending them.
