Style chooser

hye all,i hope someone can explain this.

im using satria and yesterday i change my brake pad by myself(D.I.Y),
after all complete,i test the car to do the bedding-in.(rataan lapisan :D )
i drive and brake for maybe 2 kilometres la..not braking so hard...then i come back home and thought everything is ok..BUT..when i touch my break disc,it is hot as hell,even my rims is hot!! :o only the front wheels,both of them..the rear wheels is ok..and there a smell..like something burning..i think...
