Front Brake question.....

[chilli]

Got an issue....I showed my mate the noise the front brakes were making, and he's deduced that the pads are moving, not a lot, but moving within the caliper. I'm sure it never used to do this. I'm guessing it's not just pad wear, and that something had broken/fallen off??

Think I'll take it in anyway, but was just wondeing if anyone else had experienced this?

Cheers.

You dont mention which bike but...

All pads move a little in the caliper. The pads are typically held in place by a pad retaining pin which effectively goes through a slot at the rear of the pad to prevent it going awol - this goes from one side of the caliper to the other and normally is about the thickness of a pencil lead.

Additionally the disks are almost certainly a floating design if the bike is modern, so these will naturally move too -- designed like this so they dont warp when hot etc.

Pics would help :-)

Cheers for your response, however not sure what I'd be taking pics of! If there's supposed to be a little movement of the pads, then happy days.
It's a 2006R6 by the way..... A black one(fastest).

Thanks again.

The 10R's pads move around about 1/2 mm in all directions.





If the r6 pad retaining pins are in place (examples above) then I'd not be to concerned -- if your really worried drop it into the dealer -- they'll tell instantly...

Cheers Mark,

The pins are definately there, and the play is only slight...it just never used to do it! I guess that's just down to pad wear?

Thanks again.

Floating disks etc...

Is that why I can occasionally feel a slight chatter through the front end of the bike, when braking to a standstill at low speeds?

has someone left out the anti rattle shims ? these are the spring steel bits between the pads and the pad pins on some bikes and fit between the pads and the caliper on other brands .

Well my discs are fully floating and are very loose on the carriers, they rattle like a Tamborine but there's no chatter under braking as the load is all one way, I'd say you might have suspension issues (or wavy discs?).
