Well today (finally) after buying bigger brakes a while ago I decided that the rear brake callipers and discs should be fitted as the front were fitted ages ago when I bought the setup.
Calipers and discs all came off easily with no problems.
The new brakes and discs were all fitted, few issues but all good.
When we started bleeding the brakes fluid started coming out of the handbrake part where cable fits onto.
Stripped them apart and it looks like there is possibly an O ring missing in the handbrake connection.
So unable to fix it, everything on the rear had to be removed and put back to how it was.
Hopefully Hi-Spec can repair them for me, then I can try again, they came of an ex show car so not brand new.
Yes I know they are Hi-Spec, but I couldn't resit adding a Brembo sticker
