I burnt my brakes..

[Simon8v91]

Brake discs going blue is usually not detrimental to the disc.  It happens a lot on track days etc and they return to normal after more typical driving 

As you have found out - the blue colour is caused by excessive heat.  As others have said it could be poor quality pads or not bedding in properly.  I would also suggest a lazy caliper or sticky sliders and if your alloys get hot with normal driving this seems likely.  Problems like you describe should only happen after a few high speed brake - accelerate cycles, even under load, but if your brakes were already hot.........

Cheers, i only had one in the back and the front.. but they wernt the smallest!   Was mostly curious because it hadnt happened before, gunna try some different pads I reckon. If not, new discs!

As for the wheels, they are being saved for the summer and occasions.

well you did say you had halfords own pads,  they are utter crap  stupidly easy to fade and once they have been got proper hot they don't last long    that smoke is the resin that holds teh pad together burning

Check that your calipers are not sticking slightly! If the discs have turned blue, they must have heated BEFORE you hit the breaks, boiling brake fluid, causes brake fade.. think about it
Halfords brake parts will meet a british standard, and should easily cope with a relatively light car, 3 up, from @80mph
check the calipers, and replace if required,  and replace the flexi hoses, along with some fresh brake fluid from an unopened container, re-bleed ALL the brakes

with 280mm brakes you will normaly feel if you have a binding calliper you'll feel the car stop unevenly as one side will be hot and the other not also you'll smell it when pooteling allong.

also meeting british standard dosen't mean a lot really.  compared to other pads they are crap end off.  fadeing is also mainly caused by the pad,  as the pad gets HOT it starts to gas, this gas then forces it's way out pushing the pad away from the disk.  also during this prosses the pad has a nasty habbit of glazing whitch means it'll have a lot less bite till the glaze wears off  mainly why grroved disks are avalible,  to vent the gas from pad and remove said glaze from pad.  with any resoanble pads you should be able to get the disks glowing with good pads you should be able to get them glowign quite brightly

Crap pad - Mainly metal based - hard
Good pad - Mainly fibre based - soft
