Bad Wilwood Caliper???

[TX-Lou]

So, we were trying to bleed the brakes today and we got nowhere. We were just trying to start with the rear passenger caliper and had opened up one of the posts. As my son pumped the brake we noticed a leak on the drivers side rear caliper at one of the posts. I went around and tightened up all of the posts on all of the calipers but it still dripped. I took the post off and made sure the thread was clean. When I put the post back on and tightened it up I got this as he pressurized the system:

There are no other leaks in any of our connections or any of the other calipers. Just this one and it is a gusher as you can see. It looks to me that that the post/pin in question doesn't seal when tightened. Did anyone else run into this? I'm afraid that if I try to tighten it any more it will just break off or ruin the caliper.

Thanks in advance for any help/opinions,

Lou,
Are you tightening black bleeder screw into the brass fitting?
If so, your bleeder screw is defective. Even a snug screw will stop fluid from coming out.

Take the bleeder screw out and inspect it's tip for damage.
Look into the brass hole to see if the flare seat looks damaged.

Never mind.....

Talk about not seeing the forest for the trees.....

I was so concerned about the brass fitting part of the bleeder screw I didn't even notice the small black inner screw. That is what I get for working in a dark garage. Never even noticed it was a threaded inner screw.

So, for anyone else who comes across this the inner black screw does not come tightened on the Wilwoods. You will need to tighten them all.

Now excuse me while I go put my dunce hat on and sit in the corner...

Cheers,

Thanks Bob, I was in the middle of posting my response and feeling dumb when you posted. I appreciate the reply though!

Are there bleeders on the top of the caliper, too?

I also just noticed the caliber is upside down, bleeders need to be on the top to remove trapped air.

Actually there are 4 bleeders on each caliper (two on top and two on the bottom) on these Wilwoods. We used the top ones to bleed the brakes. Everything went smoothly and there are no leaks.
