Weeping bleeders

Just replaced the rotors, pads and reman calipers on my expedition.

Got everything buttoned up and brake fluid is weeping from the bleeder threads. I've sprayed it down, wiped it clean and verified that it is dry, then rechecked after a drive and even just sitting all day (have rechecked several times) and there is always fluid around the threads.

As stated, they are reman calipers. I've verified they are tight. Loosened and tightened several times, and even gave them the full onion to get them to stop weeping.

Any thoughts? Am I just hosed and looking at another set of calipers? Odd that both sides are weeping the same....

Are they the correct bleeders for the calipers?

There is a similar problem on the Ford Truck forum. It took replacing the caliper with another one to fix the problem. It was thought that perhaps a worker at the rebuild facility was drilling out a stuck bleeder and that the angle of the drill bit did not coincide with the seat angle of the new bleeder screw.

They are the bleeder screws that came with the reman calipers. They are brand new, but not sure how I would know if they are right.

I suppose I could try the old ones and see if they work, or buy new bleeder screws and see if they work.

That's my fear ... that I get to do it all over again....

I could see one of them being wrong or miss drilled, but to have both seems odd....

They don't feel right, though. As soon as you crack the screw, it wabels loosly in the threads..... Maybe just they mounted the wrong bleeder in the calipers? That would be better than having to warranty them out....

Definitely the wrong bleeders, there should not be that much play in the threads. If the threads on those screws are not correct for the calipers, the seat angle may be wrong also.
I would try the old ones first

3/8 thread bleeders will fit where 10mm should go and be slightly loose...

That would make sense... I had to use my 3/8 inch wrench for the bleeder and no metric wrench fit which I found very odd.

I'll compare to the old ones and see what I can find. Might try the old ones and see if those work. I'd rather have new ones though since the old ones are pretty crusty.

I'll bet that's what happened. SAE bleeder in my metric caliper.... makes more sense than both of them being cracked or misdrilled.

front and rear STOCK caliper bleeder screw size is M8X1.25 it is a standard size in the motorcycle braking component arena. the correct speedbleeder part # is SB8125. i believe they throw L's at the end of the part # to indicate increased length. they do work nicely and extremely handy for automotive purposes but IMO always found them to be a waste of money for street bikes. and your "weeping" fluid? can be caused by galled bleeder seat in caliper which is extremely unlikely(have never seen it on a street bike)....nicked/dirty/corroded bleeder seat also pretty unlikely on a 9 year old street bike....residual fluid on threads and bleeder that needs re-tightened. my solution when i run into this: have rubber plug handy....remove bleeder....do NOT touch lever or pedal....squeaky clean bleeder seat and threads....Qtip clean caliper seat as best you can....put a dab of thread sealant on the bleeder(i don't use tape)....and reinstall and tighten. always works.
