Should I be worried???

Just had a quick once over today on the Disco as its nearly MOT time, I have noticed that the back brake pads have ground about 1/4" into the back hub!!!  this is on both sides, how thick is the hub at this point, am I not far off losing a wheel??  I presume already this will be an MOT failure, what is causing it, I suspect the calipers holding the pad are either worn or damaged letting them slide about (I lost a rear pad 12 months ago altogether!!)

let me know what you think please!! :shock:

hairyasswelder:
I think you just answered your own question  :wink:
New disks and calipers  :wink:
Think the calipers are worn allowing the pads to move. The damage to the 'hub' I presume is actually to the inner of the disk? so would assume the disk would part company NOT the wheel  :wink:
Either way its time to change them.

Now I think of it, yes it probably is the disc :roll:  better look for some new discs and 2nd hand calipers then I think!! :shock:

thermidorthelobster:
I'm trying to envision this but can't.  The callipers are on the outside of the disc, and the hub is on the inside.  So how can the brake pads be rubbing on the hub?  :?  Do you mean the part of the disc that sits over the top of the hub, which the wheel studs go through?  If so then it's the disc that'll end up severed.  I'm not sure how this would happen as the callipers should contain the pads.  Like Steve said, new callipers, discs and pads.

Evilgoat:
When I changed (me and Datalas) OddBod's caliper on the rear the pads were a goos 1.5mm into a brand new brake disk. Theres a protrusion that holds the pads in check and it seems to just wear off. We had 2 bloody great cable ties in there for the day while he looked for a new caliper.
