I have a Wilwood Dyna Pro calipers on the front and I have some problem on bleeding. When I open both upper bleeder valves on the calipers the fluid will not bleed from the valves instead it will come out around the bleeder valve. I checked the valve and it's clear. Also the brake paddle is very hard to push down when bleeding.The rear brake are stock and I have no problem bleeding them. The brake works fine beside it's little spongy. Does anyone have a similar problem that can share their experience. Thanks.

 

I have the same calipers on my 12.19 kit,you are opening the ''small'' bleeder valve in the center (1/4'' wrench size) aren't you, not the outer adapter?Because if you open the outer (i believe 7/16 wrench size) adapter the fluid will flow out around the adapter instead of the bleeder valve that is still closed on its seat.It took me a while to get all the air out,you really need a pressure bleeder to do the job properly.I have been told that its very hard to get the air out once its gets trapped in the ABS pump.Hope this helps.

OH.... I never realize there's a smaller bleeder valve... I will try again tomorrow. Bill, thanks a lot for your help....
