Can anyone supply a part number or specification on the bolts that hold the front Brembo calliper to the carrier.

 

I'll go into more detail on another thread but basically one of mine looks like this:

Its a 10mm hex socket head, M12 @ 73mm long but I need to find 2* of them urgently.

:angry:Looks like somebody needs a new torque wrench by the look of the stretched bolt.

Not guilty Neil. Whilst working on the brakes today found the bolt rattling looking like it was loose. Pinched it up and it fell apart. Suspect it's been  shearing for a while and I finished it off

Ive never had an Audi caliper off but surely it shouldn't be threaded all the way down it looks like the wrong bolt anyway.i would have thought it should be threaded leaving the approx thickness plain for caliper lug ( could be wrong)

No it's definitely the original bolt as the other one is the same. I've trawled online parts lists but this bolt is not listed as I suspect it is supplied to Audi with the caliper from Brembo.

I’ll have a look at etka when I get to work.
Will let you know.

[T-800]

No listing for it Rob

I’ve looked at the R8 one as it’s the bolt most use on the 8 pot upgrade
Don’t know if the length is correct though ?

[T-800]

Failing the above Rob I’ve checked against the other RS models and they all share similar bolts.
The RS3 and TTRs are the only ones to use that caliper

Maybe best to use a local bolt & nut company ? See if they can assist in supply of new ones.

[T-800]

There’s a list of popular bolts Rob
Here’s a screenshot
There’s an M12 x 70 at the bottom.
Not sure on the pitch though could be 1,5

Cheers Sean, 

 

Yes this is proving to be a pain. I suspected it wasn't an Audi part and even that R8 one you found dosen't appear to have a standard Audi part number. I think these get supplied to Audi with the caliper from Brembo. The R8 one might do if the thread pitch is okay.

 

I'm going to have a trawl locally to see what I can find.

I’ve a local Nut & Bolt place here and they are very good at finding the correct bolts etc.
Good luck.

Rob I wonder if these would suit.

Same 4 pot brembo caliper I believe.

 

Same seller supplies these for the Evo Caliper which is pretty much same setup......

I saw these too but they appear to be the bolts that hold 2 halves of the caliper together if you strip them down for a service

Ah right..........oh well...

 

I wonder if the seller could assist with your requirement though Rob ?

 

Could be worth asking the question........

Might be best contacting Brembo direct pal, explain the situation and ask about the bolt. They were exceptional with me over the years and half the time just sent parts FOC.

I had contemplated that Looch however I’m supposed to be going away to the south coast for a long weekend on Thursday so I have a strict timescale 😳

[Duke3D]

So after trawling every local, motor factors, garages and even DIY stores no bolts 

 

In desperation I headed to my local Audi dealer to find as suspected they don't list the bolt as a spare part. They offered to sell me a new caliper at £600 but i declined 

 

Clutching at straws I asked if they could supply the R8 bolt Sean identified earlier, WHT001330A, by tomorrow if i ordered them now,  'No sir' came the reply, we have those on the shelf 

 

'Ill take two' says I and £16 lighter here they are:

Comparing them to the original they look perfectly OK, slightly longer and the head is a bit smaller but good to use:

 

 IMG_0280.JPG   62.14K   10 downloads

 

 IMG_0279.JPG   38.72K   9 downloads

 

However trying to fit them proved otherwise. It appears the original bolts being threaded along the whole shank was not a mistake. The Brembo callipers on the 8P have a small threaded section at the top of the hole. they are designed for full threaded bolts that have to be wound all the way through until you reach the non threaded part of the shank under the head and then they spin free. Its a way of making them a captive bolt but not impede thread misalignment between the caliper and the carrier. Now I could have found a local engineering firm to thread the rest of the bolt but as I couldn't see it had any structural benefit I just drilled the small threaded section out of the caliper. 

 

So they're back on, Hoorah

Now just one more thing.  DOES ANYONE KNOW THE TORQUE SETTING !!!!!

 

I can't find any info on these F-ing callipers anywhere. Ive found a thread for an S8 that states 80 ft/lb so I've done them up to that at the mo. Any more guesses gratefully received.

No info regarding 8P or indeed 8V on Elsawin for Caliper to bracket Torques

 

However on the R8 Caliper (8 pot) Elsawin shows the same bolt with a tightening torque of 110nm and it does say to renew every time.

Cheers Sean, 110nm translates to 81 ft/lb in real money so I wasn't far off the mark 

[oze172]

I know its an old thread but with our cars getting older I wanted to add the right replacement bolt for future reference....don't shoot me!

 

Audi quite often list caliper bolts as part of the caliper assembly, Porsche on the other hand are also big on Brembo and consider these consumables.

 

The exact same Brembo bolt is Porsche part number 99907340201 with the description Brake Caliper Mounting Bolt M12 x 1.5 x 72.

This bolt has a torx head superceding the original socket head which is way better. Torque 110Nm.

 

Price...less than £4/each and off the shelf.
