Brake bleeder screw thread pitch and size.

BlpltGTV · #1 (**permalink**) 02-20-2009, 06:16 PM

Does anyone happen to know the thread pitch and size for a set of ATE front and rear brakes. This is for the bleed screws. I'm looking to get a set of speed bleeders.

Thanks,
Will

Centerline was selling them for Alfa systems, specific to your car as found on this page, or mabe this page.

They have them for the clutch clave cylinder too.

Thanks for the links but those are WAY over priced. Summit has them for far less, I just need the thread pitch and size.

I've worked on these things for years and as I remember the most common size is 6X1.0 but ATE makes different calipers for different applications and your best bet is to take one off and match it up with your tap and die set gauge, you do have a tap and die set, don't you?

Seriously, we have 28000+ members on the bb and no one can tell me the thread pitch and size for a 69 GTV with stock ATE brakes.

No, I don't happen to have a tap and die set, not something I need on a regular basis. I wish I had one sometimes, but don't really need one. I would pull one, of each but then I need to rebleed the whole system. A good idea, but I have better things to do with 4 hours.

I 'think' I've got an old set of stock bleeders out in the garage if you can wait til tomorrow for me to go out and look then compare it up with the tap-n-die set.

Front : 8x1.25
Rear : 7x1.0

Thanks for taking the time to do that. I'll post the part #s from summit when I get around to ordering them.

NP, I needed to go out into the world and get some oxygen anyway

NOTE:

I did a bit of spooking, and even though the above #'s are for ATE on spiders from 69 to 94, the same calipers are used on your car starting in 69 so it's a pretty fair bet that there won't be any surprises.

6x1.0 is the slave cylinder bleed screw on Alfas. My Alfetta has 7x1.0 on the brakes. My GTV has been converted to BMW 2002 calipers, so my current size of 7x1.0 on those is irrelevant to this. There is a guy on Ebay who sells them for $7 each and $5 shipping whether you buy 1 or 5 (brakes + slave). He's got a lot for sale so it's easy to find him.

Got the rears, the fronts are on backorder

The 7x1 works great, I just wish I had the fronts so I could easily finish the job.

Half is more better than none

Check some of your local parts stores. Every once in a while you'll stumble across a set or two sitting on thier shelves in the back where nobody but that one guy knows about.

They are the kitties rectum though, ain't they? LOL

Oh, side note:

Every year or two it would be worthwhile to back them out a wee bit and apply something to the threads to prevent them seizing in place. (seems even the 'structions mention something to that effect)

For one, it's nice when they work like they should, for another, if you break one of those bad boys off it ain't gonna be no joke getting it R&R'd
