Is there anything wrong in this picture?

Does investigating stone presence require taking stuff to bits? I was well impressed I got the wheel off :o

I would imagine the disk would look scored, or at least marked in some way - can you see the other side of the disk thing?
 
Not sure from that photo (besides your disc needs changing)...

Like I said...not clear in the photo but :
Is that the caliper appears to be jammed 'on' - note the discolouration just above and to the left of the pad from heat soak, where it's 'burnt' off?

Unless I'm just seeing things :)
 
The caliper could also be sticking on the rods it slides on if they havent been lubricated with copper grease for a long time, thats if you dont find anything as easy to diagnose as a stone trapped. Are both the pads about the same thickness?

The discs are in need of replacement pretty soon as well I would say.
 
Has your caliper seized? Was a smell of burning apparent when you got out of the car and had a sniff at the wheel?
 
Might sound silly this, but drive forward so it is definitely making the noise, then reverse and this might help to dislodge it. Some cars have a guard fitted to prevent stones sticking within the caliper mechanism - from your pic, it doesn't look like they are fitted. :)
 
My 206 fronts do it when they're hot. Like country road hammering hot.

The pads and discs are fine though. It usually means the pads want some copper grease behind them.

By the looks of things, you might as well just get the lot sorted at a garage instead.
 
Front pads are approx 6mm in thickness.

I've no problems with getting new discs and pads but I guess what I need to know is whether its safe to use the car or whether I'm on the bus until the weekend (omg!). Logic would dictate horrid noise = leave the car on the drive, but hmmmm.

It is fair to say they had been subjected to some 'country road hammering' immediatly before the problem started....
 
Wait for the discs to cool down...metal expands, so if the stone, (if there is indeed one there) *should* be able dislodge itself.

Do the reverse suggestion theory posted above. Failing that find a empty road and jab the brakes on and off.

Your first suggestion was a good one, letting the brakes cool will help him find and dislodge the cause. His discs need changing anyway.

But hitting the brakes on and off is going to cause a bit of stress on the mechanism, and if something is lodged in there, is only going to make it worse.
 
Happened to me just a few days ago with my brothers/dads Pajero. Turns oout it was the metal sensor indicating 'new brake pads needed fool'. Despite them looking absolutely fine. Took the brake pads out and the where fine at the top but tapered right down to nothingness. As one of the caliper pistons seized. This pushing the bottom of the pad in and not the top.

Bit of WD40 to unseize the caliper+new pads and all was well.
 
Shouldn't be too difficult to whip the offending caliper off and drop the pads out to check for stones/gravel. Going by the meat left on them, it would be an ideal time to swap 'em for new pads ( other side too, obviously ) , better safe than sorry, dinae take chances wi' yer brakes. :cool:

If the bolts are stubborn, a bit of WD40 and an impact driver should soon have 'em off.
 
I "think" that your metal clip is on wrong actually.

Should be behind that "lump" providing some tension AFAIK.

Probably the wear indicator grinding on the disc as its supposed to.

What!? A small cable which would be almost impossible to hear!? Or are you talking about the non-electronic ones!

Fox, IMHO the discs need changing, there is a massive lip there (and whilst not dangerous) you've noticed noise. It could be a hot warped disc, that when its cooled down will play ball again! Alternatively, as suggested, its a stone, but there is no point trying to put something thin between the pads and disc as there will be no room. The pads sit on the disc (albeit lightly) permanently and self adjust.

Hope you get it sorted. BTW, well done on removing the wheel! ;) :D
 
it shouldn't be that hard to remove the pads and take a look, there should be some kind of pin, just remove it and swing the caliper up - the pads should just drop out.

but as others have said you disc does look worn, there's a noticable lip on the disc. I'd probably keep driving it and whack it in a garage for new front discs+pads+alignment.

No the ones that have a bit of metal that touchs the disk.

TBH the disks and pads look ****** to me. The disks look about 5 years old too :eek:

Si - 2 sets of pads and one pair of 310mm disks in 1 year :o

No swearing!! FF.
 
Actually, it would also be an idea to look at the other side and compare the wear on the pads and possibly the disc. This might give you a clue as to whether any pistons have seized and are causing excessive wear to one side.

Thats assuming the other wheel comes off Ok. :p
