Look for missing anti-rattle bits and/or take it to a reputable brake specialist for diagnosis.

Thunk thunk on braking

But if you listen closely you can just hear it when it goes over uneven road, with the "thunk"

It's much more noticeable if you are going really slowly- say a car park for example, doing speed of less than 10km/h, and if the concrete slabs aren't joined together properly, you'll hear a thunk thunk, or clunk clunk, once you go over the uneven bump,oOr over a speed hump.

So I would say its proportional to the speed, because if I'm going 60km/h then thunk will be faster.

Here's the thing though. When I'm going slow and not on the brakes, there's definitely no sound. It's only when I apply the brakes that I hear anything.

As mentioned, it's hard to test at normal driving speeds, but I'm fairly sure it's not there unless I'm actually on brakes.

I intend to have a look at it this weekend and see if I can find anything. If not, I might head up to Mania and get them to have a looksee.
