Brake bleeder screw dimensions

[Bepis_Corgo]

Hello,

I stripped one of my brake bleeding screws, and want to replace it as I'm getting ready to flush my brakes.

I see the OEM ones, but nothing about dimensions. Didn't see anything in ShopKey Pro either. I don't want to buy the wrong size. Anyone know the pitch/thread/length?

Thank-you for your time.

Brembo brakes?
Did you strip the hex?

I honestly would have expected the threads in the aluminum caliper to strip first?

same question as post 2
the bleeders are steel and the calipers are aluminum so I can't imagine it's even possible to strip the bleeder
Plus, how did you strip them if you are "getting ready" to do brake work?

very confusing

Maybe he means he stripped the head not the threads, I have stripped lots of heads on various cars...never the threads.
usually when you have to revert to vice grips to get them out if the head is rusted.
Im sure they are very generic bleeders, most auto parts store could match them up if you brought it in

This sounds like a case for the patented R.B.R.T technology...

(Rounded bolt removal technology)

It's all about the grip, and not the slip.

sheesh how old is this car? Out of the probably 10 vehicles over the years I've done brake work on I've never once seen a bleeder with significant corrosion or even close to the point that the hex would strip off

My guess is it was overtightened. And maybe the overtightening even started to round the hex, and trying to loosen finished it off. I had a much older car where that had clearly happened. Ended up replacing them with Speed Bleeders, but every bleeder valve since that's worked itself more than wrist tight makes me paranoid. They seem so fragile.

I always use a 6 point socket to break the bleeders lose first time around. Then use a small (5"?) wrench to loosen/tighten.

I live in eastern canada where its the rust belt...we use salt for road deicing.
And I owned lots of beaters in my day.....lol

Did any of those beaters utilize aluminum Brembo monoblock calipers?

Nope, They were all of the standard single piston variety. Rear Brake slave cylinders from the old drums were the worst for bleeders going bad..

 

[rtv900]

my guess would be didn't use the right size wrench and knocked the corners off the hex and maybe way overtightened on top of that

^ha ha ha
yeah seriously
lot's of beaters out there with fixed brembos
