My nearside front brake caliper piston was knacked and causing the brakes to bind on the disc, which has been the case for a couple of weeks (had to wait until pay day to sort it). The pads were also knew as of about a month ago, so I'm not sure if they'd bed in properly before it started to go (I'd done a quick fix on the caliper when I changed the pads).
I've just changed the calliper and the edge of the disk (the top if looking down on it) is rubbing on the caliper. There's a lot of rust there on the edge of the disc so I'm not sure if that's relevant. My mate said he thinks t hey're 'warped', but my stepdad said it could be a build up of rust that should be 'knocked off' - anyone had any experience of this?
Further problem is that when I brake the brakes are really ineffective and the pedal goes pretty much down to the floor. I think this suggests I've not bled it properly, but a further problem is that its grinding against the disk and juddering when I brake. The car does stop but it doesn't sound very healthy at all and sounds like its metal on metal (although the pad's thickness seems more than ok).
I've just read a few articles and it said this might be caused by deposits on the disc from the brakes getting too hot, while the juddering may be caused by the brake fluid boiling. Does this sound like an accurate diagnosis, and if so what course of action should I take?
