Brake Caliper Bleed Screws won't stop leaking
I just completed the annual service on my 2005 LT. This included the installation of new brake pads and the annual brake flush.
Back story… Several years ago, after reading threads on this forum about speed bleeders, I purchased a complete set of the screws for my bike. I later determined that they aren't really needed to perform the flush, so I never installed them.
So fast forward to last week, I find the unopened bleed screws in the original packaging and in a moment of brilliance, I decide that it would be a good idea to install them on the bike. I completed the install and system flush with no problems, at least I thought. I went out for a ride and noticed leakage from the bleed hole (not threads) on both rear caliper bleed screws. I tightened them down more, still they leaked. So I decided to place the original screws back in the caliper… now they are leaking as well (from the bleed hole, not the threads). I can’t torque them down any further. Prior to this situation, I’ve never had leak issues with the bleed screws.
My concern is, Why is it leaking from the bleed hole, but not the threads, and how do I make it stop?
Options I’m thinking about:
1) Putting thread sealant on the original screws and reinstalling.
2) I have another set of unopened speed bleeders, SB1010, not the SB1010S that I could try. The SB1010 is a longer screw.
3) Ordering replacement OEM screws.
Thanks in advance.
