I have a strange rattle since changing the front discs and pads on my MY04 Blob WRX. The best way to describe it is a pencil being rattled in a yoghurt pot. It only happens when I'm accelerating, strange thing is it goes away when I press the brake pedal with my left foot and the accelerate atthe same time. I had to give the pins a good bit of wacking to get them out as they had seized in, this bent them. These have been replaced with new items as well as the pad springs and retaining bits. 2 of the pistons on each caliper where seized as well but managed to free these off. Car feels fine and pulls well, could I have loosened something off that would cause this?

Anyone got any ideas what it could be? There is no noise when reving while stationary just while moving. Its starting to do my head in.

I bet you have removed the anti rattle shims and forgot to put them back on.They are brass clips that clip onto the back of the caliper and stop the pads from rattling

Nope they are on there made sure when I did them as I've left them out on a prevoius car I had.

There goes my theory then. Hmmmmmm - calipers lose?

All tightened back up as I had to replace all four caliper bolts as they were seized and ended up a bit rounded off by the time I'd finished. It really is spoiling the car as I thought there was something wrong with the engine at first.
