Speed bleeders -- size?
 

Want to get speed bleeders but don't know exact diameter, thread pitch, and overall length. Don't want to take the screw off to find out and introduce air into the system...

Using my little measuring calipers I got about 3/8'' (10mm?) for the rear, and about 5/16 (8.5mm?) for the front diameter. But obviously I don't know the length or pitch. The guy @ www.raceshopper.com -- where I usually get my speed bleeders -- did not know, but did tell me "Bleeder screws are available in 3/8", 5/16", 8mm, or 10mm. - AND they are all different."

The local Mazda parts counter did not know either. I will call another Mazda parts counter and see if they have one in stock and can measure it for me. I will also buy a FSM and see if that tells me. But I'm not sure either will help...

The answer is in the Speed Bleeder thread

From a raceshopper invoice. Note that these are not on my car, but another forum member has them.

2 speed Bleeders for front calipers RX-8 SB8100 7mm x 1.0 - 34mmL
2 speed bleeders for rear calipers RX-8 SB1010 10mm x 1.0 - 34mmL
2 speed Bleeder clutch RX-8 /master cylinder SB7100 8mm x 1.0 - 34mmL

:)

oh poo does the clutch and brakes share a master?? in which case I'd need to bleed both?? what about an ABS unit that needs bleeding?

i lost track of time and have forgotten about the *ONLY TWO* FSM's on ebay... hopefully another one will pop up sometime... but maybe not b/f I get to the brakes...

thank you for the part #'s. why didn't Edwin @ raceshopper not know what I was talking about... if he had sold them before?!

2 8MM for front brakes
2 7mm...master cylinder and clutch slave
2 10mm rear brakes

Part #'s above

This thread ranks higher than the other one for some reason and so to not have to sift through that entire other thread like I did since the first page is full of confusion...
