I tried to bleed my brakes and found that my rear right bleeder screw was snapped in half and on my left rear, after smelling Fc fumes all day, I forgot my "righty tighty lefty loosey and broke it off. I tried to search but couldn't figure out the thread pitch size.... Halp!!!!

 

248 threads popped.
I got this:

i'd recommend some speed bleeders also (while you're at it). Russell makes them, so they can be found at most parts stores, for like $11 a pair. I bled my brakes by myself in like 5 minutes. its amazing.
the key to bleeders is use an 8mm wrench (cuz theyre small) and dont put muscle into it! just tighten till they re snug, and make sure you cant loosen them by hand (no wrench)
front - M8 x 1.0 x 35.15 (SB8100)
rear - M7 x 1.0 x 35.15 (SB7100)

 

Just ordered those, though the part numbers were different. 35 bucks for all 4, shipped. Nobody had them locally.

 

would you be so kind as to put the part number you used in this thread for future use? :P

 

Front Part # 639550

Rear Part # 639570

2 of each needed... Duhhhh

 

Awesome!! Thanks dudes!!! Now do you know a good way to get the broken screws out?

 

Screw extractor would probably work... Russell, the make of the above speed bleeders even states that their bleeder screws are intentionally NOT hardened to aide in the removal in case the end user over-torques them.

If they're just stripped, I've used vice grips with a ton of success. Heating the area around the screw with a pencil torch would probably help too.
