Problem with Leaking Bleeder Screws
CF,
I am installing braided brake line and just had my calipers powdercoated. I installed everything this morning and both rear calipers are leaking through the bleeder screw's end. I have tried three sets of bleeder screws (GM's, NAPA, and Russell's Speed Bleeders) and they all three leak through the hole on the end. All three sets appear to bottom out against the nut head and the caliper.
Any ideas? What does the tapered end on tyhebleeder screw seat up against? Could the seats be damaged (on both calipers???)?
Is it time for new rear calipers?
Regards,
DKHIGHPERF

Wondering if the bleeder screw's seat inside the caliper may have a little powder coating or other debris. Powdercoaters typically use silicone plugs in threaded fittings to prevent them from getting coated. Try removing the bleeder screw and get a good look up inside the hole. If necessary, remove the caliper and get it out into a strong light for inspection.

Also, check the screws you're using against the fronts. All four should be the same length.

Leaking with Speed Bleeders
I removed, painted and rebuilt my calipers last summer. No paint or debris in the bleeder holes. In stalled speed bleedrs and torqued them to spec. Two of them leaked. I wound up torqueing to spec and going 1/2 turn more. They don't leak now.

Get a round wire brush of small diameter and try cleaning out the holes.
Are sure that they are not spread out from over torquing ? My bleeded heads do not touch the surface of the calipers.

Copper washer? The bleeder screws don't use a washer, copper or otherwise. By any chance are you referring to the brake hose attachment to the caliper?
