Adjustable Disc Brake Proportioning Valve

[comet_666]

Running manual disk/drum and I am using this prop valve. Have about 80 miles on car and poof! if is leaking out of the stem. POL says it could be a O Ring gone bad. I think the part is just a piece of crap. Anyone used this or have issues?

Never used this one, but havent had any issues with my wilwood adjustable prop valve...  like 100k miles and no isuues.  People also love the speedway mini adjustable prop valve.  Little brass thing and nobody has reported any leaks with them...

I run 205/75 front tires, 275/60 rear. Disc conversion on front, stock drum rear and NO PROP valve. No issues with distribution or lockup.
