I recently had my Stoptech calipers rebuilt. Now a few of the bleeder screws are leaking. I will attempt to clean them out with a brush. Has anyone tried a hydraulic thread sealer?

Just replace it, the system is not difficult to power bleed.

Yeah. All of the bleed screws are new. I think I will order some new ones. Clean the out the calipers reassemble and hope that works.

Almost makes me wonder about the new bleeder screws not having the proper taper interface to the seat causing the leak?
Tantamount to bad valves/valve seats in a cylinder head.
Just a guess from afar.

Try giving Dave a call over at Zeckhausen a call. A leading Stop Tech dealer and a very smart brake guy. We've had many a deep discussion about Mue slip VS tire grip VS electronic intervention. Besides being a smart MF, possesses deep knowledge of the ST Line.

Yeah the shop that powder coated and rebuilt them installed new bleed screws. I’m hoping there is just debris still in the caliper.

Agree with the questions on the bleeders. Hopefully they did not powdercoat the bleeder seats, or the new bleeder valves to make them look cool? I'd reach out to obtain the specific ones for these calipers from a source that will get you OEM hardness, diameter and taper angle.
