Leaking front bleeder screw, caliper

Recommended Posts

I noticed dampness around my front caliper bleeder screw.

The screw appears to be tight. Maybe not tight enough?

Is there a seal under the screw or is it sealed simply by tightening?

thanks

Remove it and replace the O-ring, reinstall.

Huh? O ring? :thumbsup:

I replaced my bleed screws with "speed bleeders"...Quick and easy brake bleeding. They're sealed with thread sealant, and simply tightening them.

Apply a bit of pressure to the brake lever, loosen the screw a skosh, tighten it back down if there may be debris where it seals.

Or just tighten it a bit more. I have never seen a bleeder leak that wasn't just plain loose.

There is no seal or o-ring, it's just metal-on-metal.

Get a new bleeder screw, it has been deformed, most likely crushed a little on the side with the cross hole right above the seat. It happens sometimes from overtightening, and gets worse with time goes as you try to stop it by tightening a little more

So I loosen the bleeder a bit and re-tightened. Still leaking. Then I tightened it a bit more. Still leaking.

So is the consensus to replace the bleeder valve?

So I ordered the bleeder valve. I unscrewed the "old" one and it looked identical to the new one. The cone at that end of the screw looked blemish free. Screwed the new one in and it still leaked.

So....I put a socket on it and gave it a good twist. Leaking stopped.

Maybe I got lucky.

nice, too bad you spent money, but it's hard to tell what "tight" is by text, so it wasn't too tight afterall.:busted:

Sorry for the misdiagnosis, took a shot, hate being wrong, been wrong before, I did get married once.:busted:
