Wilwood 4 piston calipers. Anyone have problems?

Bleeding them ? 4 bleeders 2 top and 2 bottom.
The only way they worked was to completely remove the bleeder.
Darn things don't work properly 😕

front or back?....my rears gravity bleed but my fronts will not. I hope you are only bleeding the top outside bleeder.

The rears that came on my Strange 9"
I bled from outside first and when I did the inner fluid was already there.
I got the whole car bled. That's not the issue. Its the bleeder fittings in the rear calipers that don't bleed. Just Strange. 😆

not to sound foolish but can you see all the way through the bleeders if you take them out and look down them?
I've seen people try and bleed these with the ones facing the ground too.it's pretty a good watch..

Yeah I checked that. Hole on both ends but you cannot see thru it. Almost looks like a valve inside or something?

that's odd.maybe the bleeder's are no good?machined wrong?pull caliper,flip it over,pull the ones from the bottom and see if they're blocked as well.you won't have to re-bleed it either.

I pulled a bottom one. It's the same
Never had bleeders that won't bleed

that's odd.call strange as the diff came from them.maybe they'll refer you to wilwood.

Bleed the tops, might need a little more pressure to open the bleeders. I used a little hose on the nipple into a jar and had the GF push the pedal and it worked pretty good. Also back them off a tad more than you think, they will work.

I like to use teflon tape on the threads of the bleeders so air can't sneak by the threads
