i have Centric remanufactured calipers and ordered bleeder screws from the local Auto Parts for an S2000, only what I got was the wrong size (8x1.25). The Centric screws are 10x1.25 which according to Centric should be OEM size. So either the auto parts store is wrong or Centric replaces the OEM with a larger screw. 10x1.25 is not an easy size to find so I was just going to get OEM Honda from Majestic, but I wanted to be sure OEM is in fact 10x1.25 (what Centric is saying they use). So could someone confirm?

Ok I should have just searched, a quick search of Russel Speed bleeders turned up that they are 10x1.25, maybe I will grab those

M10x1.25mm is correct, I've replaced my front ones before.

I have a front one that seems to not make a 100% seal. I could suck out brake fluid with a vacuum pump while it was closed. Did you change your for a similar reason?

Should I replace just this one, or both fronts or all 4?

When you replace it, you just unscrew it untill it comes out and then screw in the new one? Does a lot of brake fluid come out while doing this? And get much air in the system?

How tight should I screw them in? Im affraid to over tighten or keep them too loose, but tightening them hard feels like it will brake or brake the caliper. Ive heard people brakeng them. I dont have a torque wrench for this low torque setting. Should I get one torque wrench for these screws?

Many questions, hope you can help. Today was my first blrake bleed so im still learning.

Thanks in advance!

There is a small amount of fluid left in the threads and inside the bleeder after you done a bleed and close it.
This can sometimes make you think it's leaking so I usually put in small paper bits and try to suck most of it out.
I did overtorque mine slightly but they still kept seeping out small amount after a drive so that's why I replaced mine.
Torque wrench is always nice to have and helps a lot to calibrate inexperienced wrenching hands.
I think the torque spec is only 9Nm so it's not much at.

Replacing the bleeders is very easy and it wont leak much fluid at all, just keep a rag ready and thread in the new one right away.
There is not really any easy way for air to enter so bleeding is done very quickly.
