Could anyone tell me what the missing bit on the brake disc is for please ?

These are brand new front disks fitted to a J11.

Thanks.

Lanstrom, when I first saw your photo it looked to me to be a possible NC Machining Error where the Cutter had dug in (Programme Error) and had been accepted by Quality Control as it would not affect Braking or Safety. But now after looking around I found the attached photo and this Machined Cutout is also there. Could this be used in Production or in Service as a Brake Setup or even for the Disc Manufacture - Dave ;)

Thanks for spotting that image. I had a look on Google Images myself but I couldn't see anything due to people using generic images. I did check out the opposite (OSF) discs and they also had an indentation although it was half the size.

Now I have just noticed that the garage have charged me £530.21 for a Full Service and new Brake Discs/Pads. According to Nissans web site https://www.nissan.co.uk/ownership/niss ... epair.html these should be fixed cost at £269 (Service) and £239 (discs/pads) so it looks like I have to phone them up now (unless I have missed something) :(

Perhaps the machining is to balance the disc rather than adding weights?

Switchback, well done I think you have cracked it 10/10 :D . These sort of points are always interesting and to find a solution even more worth while. Lanstrom, this could well answer your question !. Take a look at the attachment - Dave ;)

And there was me thinking it might possibly be a maximum wear indicator!

I was always told it was the wear indicator.
