Finally got around to fitting the rear brake upgrade, as usual there were issues but nothing major.
So to start off the problem, the new calipers while almost identical in dimensions and having the same piston size and handbrake mechanism doesn't fit. Not really an issue as the carriers cost more on their own than with calipers so they were kind of freebies. So I used the original calipers.
Original 280mm disc next to new 302mm disc.
Not really much of a difference with it being only 22mm
Anyway new disc and carrier fitted and old and new carriers so you can see the difference.
Now the other minor issue, the old calipers need stripping down as one has a torn boot and the other is getting a bit stiff. It has loosened up with being wound in and pushed back out a few times but it's on its way out. Anyway all back together.
