Hello,

 

Just wondering if anyone knew what size and thread the banjo bolts for the 2 metal hydraulic lines that are attached to the rack? (see picture below and circled in green)

 

 

They aren't listed in the online VAG parts catalogue

 

 

I undid them with a 13mm spanner, so I would have thought M8...but when I tried blanking the hole, before I painted, with another M8 it was way too small. So i guess M10? but I don't know they pitch?

 

I would just use the old ones, except I rounded 2 of them getting them off and now need replacements.

Not sure if this diagram will help ?  http://volkswagen.7zap.com/en/rdw/polo+derby+vento-ind/po/2001-240/4/422-422060/#22A

Nope, that is the same diagram I have seen. It tells you bolt sizes for the hoses from the pump to the rack. But doesn't quote the bolt sizes for the 2 little metal hydraulic lines bolted to the body of the rack....

Yeah, thinking about it, they won't list them as they are part of the whole rack assembly, I think you'll find they are fine thread 1.0 at least the banjo bolts for my brake calipers were, as I bought  M10 & M12 x 1.0 taps to clear the threads  

I've just been outside and gone through all my bolts, I have bolts from the calipers I have just taken off the car. They are M10 x 1.5...correct size too coarse pitch.

 

Also some from my G60 calipers I've just put on, M10 x 1.00.....the pitch is too fine, so I guess it is in the middle at 1.25?

 

Thanks for mentioning calipers Nige, it got me thinking!!

Have you got a thread gauge to double check ? might be some weird imperial thread !!

I haven't got a thread gauge unfortunately, I'm going to get a M10 x 1,25 bolt to check before purchasing new banjo bolts!
