Several years ago I upgraded the rear brakes on my F-Type from "performance" 326 mm to "super performance" 376 mm.
There is a thread or at least a series of posts about it around here somewhere but can I find it, no way!
Anyway the major hassle I had was getting brake fluid into/through the new calipers (bought new on Fleabay) and eventually I found that the holes in the calipers into which the brake line banjo bolts go had been plugged up with screws/plugs which were very difficult to see. Then when I tried to screw them out (hex/allen head around 3/8") they were stuck so hard I eventually rounded them off, and in the end I had to drill them out.
For years now I wondered about those blanking plugs and WTF were they doing in there, then lo and behold I just came across this vid by South Main Auto:
So apparently those blanking plugs are reasonably common and not some strange anomaly like I first thought, moral of the story beware if/when you go to fit new brake calipers to an F-Type!

Edit - forgot to add that when I first put the banjo bolts into those holes they did up nice and tight and everything seemed good to go, it's just that I could not get any brake fluid into the calipers no matter what I tried. It took several hours of head scratching and removal/refitting/inspection until I finally figured out what was going on, those plugs were buried way down deep and very difficult to see. So yes as Eric O surmised it would be quite possible to assume everything was good to go and then discover you had zero rear brakes!

 

Wow, another methodology to make these cars unfriendly to work on! I thought my 2013 VW golf was bad.

What is suggested for removing these plugs? Are they referenced anywhere in the Service Manual(s) ??

 

He simply used a small impact driver and I assume a hex bit and zipped it out real easy.
Nothing about them in the service manual which is not surprising as they don't exist on a new/working car!

 

"Nothing about them in the service manual which is not surprising as they don't exist on a new/working car!"

You don't need to know when you buy the car. But, when you SERVICE it...

This strikes me as something written by a technical writer - but not someone who had actually done the repair.

Thanks for this (and all your other helpful posts). Cheers.
