Took the car out for a spirited drive the other day.
Once the discs got hot after some hard braking the car started to 'wobble' under braking. You could feel it in the pedal and in the steering wheel. Only when they were hot though. This also happened in my old WRX aswell but ended up being there permanantly............Anyone know why or how to fix as im sure its not right!!

My focus rs did this was warped disks on front changed them was fine after that might be worth see if they are warped and grease and clean your callipers

I would be personally pulling the caliper off and checking the pistons are not seized, if they appear all ok then its almost down to warped discs.

I'd say warped discs or disc as they get hotter they get softer if you know what I mean so they get more movement check discs be could only be the one of them but if it is I would change them both anyway

Always do brakes in pairs. New discs is new pads too IMHO.

If they are expensive discs, you could take em off & get them skimmed!
Cost around £30 for a pair, once skimmed you must replace brake pads as they will have uneven wear
