Puggy 107 brakes under warranty?

Usual cause of warped disks is keeping the foot on the pedal when stationary after heavy(ish) braking, so possibly owner-inflicted if considered a fault.

The same mis-use can also cause minute amounts of material to be transferred to the disk in one area. Aggressive cleaning with a Scotch pad is worth a try.

If you are replacing the car at the same dealer, it might be worth mentioning the fact?

Chris

Thanks for the reply. I have just looked and the car we were going to buy has a hill stop facility as does my 5008 in which I understand the pads are held against the discs. Would this be likely to cause the same problem?

There's every possibility I guess.

Chris

Discs don't actually warp - it's just a catch all term put about by the trade (*) - they might just be mucky from type of use and a good scrub might work; I have used steel wool soaked in meths. Cars now seem to come without backplates so it should be possible to do it without dismantling other than taking the wheels off.

(*) On a similar note, our KA's discs are worn to the limit and a genuine reason for replacement. The discs and pads come to ?30. We have been quoted ?180 for the job. So an hour or so labour. The "warped" disc idea is obviously good to help keep the business ticking over.

My first disc-braked car was a three-years old 1966 Hillman Super Minx.

I have never, ever found rusty discs do anything other than grab and squeal on the first application of the day.

OTOH, new discs/pads can cause judder after a few hundred miles from new if not treated properly.

Chris

Mu mum had one of those, the garage stopped the squeal by spraying oil on the discs.

Depends how rusty you let them get, you'd be surprised how bad the insides of some peoples are

Yup, but sitting with ones foot on the brake has nothing to do with it.

I beg to disagree; I was dubious at first, but if you Google the evidence is overwhelming.

Chris

Thanks David. I went out in the car today and was of the opinion that the pads were grabbing and letting go rather than shaking from side to side so I might well try the steel wool with meths treatment before shelling out cash.

If it comes to it I have been quoted £98 for discs and pads.

Found this;

Stoptech are marketing their own stuff, but if you've got garb & release feeling then sanding the discs fixes the worst of it, easiest way is sit the front on axle stands, put it in 1st (unless its 4wd 4wd or rwd for the hard of understanding), let it idle & apply an orbital sander to the disc.

I'd say it has had hard use if it needs new discs and pads at 7500 miles.

Disks do warp, ths can be due to a fault in manufacture, over heating or rapid cooling .

The car had 4000 on it when I got it with FSH and I am an extremely light footed driver as is the missus.

I finally managed to have a look at the discs today and one side has grooves dug in it so it's booked in tomorrow at my local exhaust place for new discs and pads.

I'm a bit peeved at Peugeot over this as they wanted me to sign a disclaimer that I would pay a bill if they decided that it was down to normal wear only (At 7000!) It wouldn't have hurt them to have a quick look at the discs.

So it is wear, then.

Seems fair.

And yet it HAS turned out to be wear, hasn't it?

How long do you reckon it'd take for a mechanic to take the car into the workshop, onto an empty ramp, into the air, both front wheels off - come and find you to tell you that, yes, it is wear - so it's not warranty, but chargeable - then when you decide that you'll take the car somewhere cheaper, thank you very much, to put the wheels back on, back to the ground, and back it out. Half an hour, all in? Half an hour in which that ramp and that mechanic could have been doing chargeable work.

That was my initial reaction but why only one side? That suggests a faulty device.

It was the blank cheque attitude I objected to.

You can see the discs and pads through the wheel spokes so yep five minutes to look which might have given me some confidence to tell them to go ahead. The garage doing the work did just that. No charge to look at it and more (less?) than half the price that Peugeot wanted.

No. It suggests a pad that's been worn so low as to cut a groove in the disc, or something that's got lodged between caliper and disc - a stone, p'raps, or a bolt that's been thrown up from the road.

Not unusual for discs to have scores - stones etc can get wedged in them. But that doesn't necessarily make for judder.
