Dunno could be pad transfer? That can make the discs feel warped
Had you been using the brakes hard previously?

Robin

not really? I just drive the car normal, dont usually slam or hit the brakes hard.

Wat do you mean by pad transfer?

Pads seem about half worn

If it's discs you'll feel it though the pedal, if it's through the wheel only look elsewhere, eg. ball joints / track rod ends.

but I doubt its that if you've not been braking hard, or often leave you foot on the brakes for long distances

Something I learned from time in a race team.

If you use your brakes sufficient to get the discs hot, and then come to a halt & sit with your foot on the pedal (brakes applied), there is a build up of heat between the pads and the disc, while the rest of the disc radiates and disperses heat.
This causes the disc to warp. The severity of the warp is dependant on the amount of heat, duration of contact, etc but it IS evident.

Just think about it next time you stop at some traffic lights & can't be arsed to use the handbrake :wink:

Did you read the link above?
More likely to be pad transfer than actual warping, but the same effect at the end of the day!
