Torque spec for rear brake bleeder valve? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

ddeflyer · 08-08-2014, 03:50 PM

Does anyone know what the toruque specification for the rear brake's bleeder valve is? I think I've been under tightening it (used a torque wrench on my AP kit's valve and was was quite under torquing them).

"Snug" - Sorry I don't know but I've never once torqued a brake bleeder. Just make it tight, it doesn't need a lot of torque. I'd guess 10-15ft-lbs at most.

Yeah, the AP racing bleeders are 12.5 ft/lbs so that sounds about right though a specific spec rating would be awesome for precision/assurance.

Found it in a DIY thread by F1point4. It's 5.9ftlbs/8.0 Nm.

Wow, glad I didn't do the 12.5 that the AP brakes call for!

Bah mine probably have 10-20 ftlbs. It's all good.

Since we are on the topic, does anyone use speed bleeders? I was thinking of getting some but I don't know if they would actually help since it seems the only trouble I have bleeding my brakes by myself is air getting by the threads, not back in through the hose.

I use a bottle with a one way valve if I have to do it by myself. I've never had any issues doing it that way.

I'm lazy and use the Motiv. When I installed my AP calipers it made it a breeze. I've had good luck with speed bleeders in the past though, just don't over torque them because they'll snap off.

Word of caution on torquing the bleeders, don't use a big ass torque wrench. Unless you have one that reads from like 0-30ft-lbs, it's not going to be accurate at 6ft-lbs. Just make them snug.
