Hi I have noticed the rear disks on my fabia vrs had gone very rusty and only seem to be using a tiny bit of the disk,

Upon inspection I noticed the pads were worn funny so I replaced the disks and pads

I then drove about 2 miles and realised by the smell that the handbrake arm wasn't releasing fully on the o/s/r

So I fitted the 1k0 return springs witch have sorted that problem out but the pads on that side still sound like they are squealing when am driving slowly

When i jack up the car the wheels are free but you can hearing them catching a bit

what else could I do to stop this

Did you use copper grease on the back of the pads, usually stops the squealing

ensure calipers were wound back fully and moving freely

check pad sliders and pad location in carrier

check return springs cause arm to fully return

readjust handbrake

finally, the big one, NEW rear calipers (I'm gonna have to do this soon i think)

If I ajust the handbrake that might do it because it's only it about 3 clicks now, am I right in thinking its the 10mm nut under the rear ashtray

Yes, the yoke bit should lie "across" the car at all times, if not then one of the levers/brakes is still seizing.

I've got a similar problem on my Fabia - the driver's side rear brake disc has about a 1cm unswept area from the outer edge of the disc.

All other discs are fine.

I fitted the discs and pads myself, so confidently can say they were fitted properly.

I've removed and recleaned them, wire brushed all rust away from the carriers etc, re-greased everywhere the pads contact to the carrier

Re-bled the brake system fully with fresh VW oil,

fitted the springs to the handbrake mech too

Still doesn't sweep that part of the disc.

Thinking it maybe a lazy caliper now,

Someone said it could be mis-matched discs/pads, but this problem only happens on one side, so I am thinking it's more a problem with this caliper.

And from reading on this forum, lots of ppl seem to have problems similar on that particular side (osr)

I think that you will find that once an area of the disc has ended up with an establish "growth" of rust, that area will now never get cleared by freeing everything up and re-assembling bits. You would need to skim that rusting area off, ie remove metal right across the disc(s) face(s) as well as "dressing" the pad(s) - doing that eats into the disc(s) and pad(s) remaining life and costs money, so it never usually gets done - new discs and pads or tolerate how things are is the way to go.

But why does this happen?

Surely as the pad is pressed by the caliper/carrier, then it pushes into the disc... There should be a fairly even pressure distributed across the back of the pad, which should in turn push the pad evenly into the disc.

What happens now is there would be uneven wear at the outer edge doesn't touch the disc (hence the rust area), and also the same can be said for the pad - the pad ends up looking stepped where it hasn't ever touched the disc.

But if it's being pressed from behind, then it should be pushing into the disc across the entire face of the pad?!!!

Which then goes back to me thinking along the lines that there must be a hinderance somewhere causing uneven movement of the pad - perhaps a sticking pad (caused by rust on the carrier), or sticking pin, or I just don't know
