Rear mate, there putting groovs in the discs already, somets wrong big time

Did you wind the pistons on the calipers right in when you fitted the new disc's and pads?

If not - try doing that.
Clamp brake pipe and open bleed nipple before you do

Can help - but often points to sticking calipers im afraid and will need changing..

also check that the handbrake cable isnt too tight / caught..
