B9 S4/S5 Brakes


Registered User
Should anyone wish to change their front pads on a B9 S4/S5, then a special socket is needed.

It is a 22mm 7 pin (AS-22) socket which you can buy online from Amazon for around £7

A lot of garages DO NOT have this tool, therefore cannot do the job. Best to check they have one first before booking in!!

Thanks for the info!

Sorry to be an ***, do you have any links, a google search brings up lots of varied links to oxygen sensor tools etc!

Would like to pick one up for the collection (money spend on tools is never wasted!).
