Default overheating disc

I changed my pads for Ferodo DS2500 and discs on my classic (4pots) and took it out for a quick run and when i came home i noticed that one of the discs has overheated and has gone blue/brown, any ideas as to why this has happened?

sounds like you have sticky pistons in the caliper
it may need new seals and cleaning up a bit

remove caliper from disc, remove pads, pump brakes till piston protrudes then clean them in-situ and push them back, then replace brake pads (in same place they came came from)
if its still sticky then you need to push it all the way out and remove seals, clean grooves tat the seals sit in, clean or replace seals, clean pistons and reassemble

or I believe someone does part-ex reconditioned calipers on here, if yours are very bad
