2 probs - clunking and worn brake discs

[Anonymous]

Hi,

I have two problems if anyone has some good advice please....

When I'm going slowly and go over a bump I hear a clunk type noise from the back.  It appeared suddenly and only seems to be there at slow speeds.  It doesn't need much of a bump either, maybe even happens on the flat, hard to tell.  We've tried seeing if anything is lose and all seems fine.  Any suggestions?

I need to replace disks and pads all round.  I replaced front disks (used Mintex disks) less than 1yr ago and they're already very worn, though the green stuff pads replaced at the same time still look new.  The back disks have worn at a more acceptible rate - they were just OK last year and now just not-OK (they also have the same green stuff pads).  Disks and pads seem SO expensive - has anyone found a good deal?  Anyone else experienced disks wearing too quickly without any good excuse like too much heavy braking?

I've checked previous posts, but can't really find what I need.

Thank you!!!!
