Brake Disks

    I was travelling to work this morning in in trusty 04 Almera H/B when I heard a rubbing noise from the front of the car. I slowed down as the car felt a tad lethargic and after about a mile I pulled up as I wasn't happy. When I got out I noticed smoke coming from the front driver side wheel and as I'm not exactly very familiar with the workings of a car I gave a call to a person in the know. They told me to let it cool and drive on slowly as it was more than likely a problem with disks/pads/calipers.Anyway brough it into the garage adjacent to work and he informs me that the disks are shot. He asked me did I live by the sea. I've never used this fellow before but have been told he's quite good. Would the disks being shot cause the wheels to smoke like that? How much will it cost me to fix?Any advice would be much appreciated.

    brake disks are approx eu 75 to eu100 each. You'll need pads as well, and labour - so you are up to eu250-300 I'd say.

    Not a mechanic but I would speculate that the car was sluggish & the disk got extremely hot because something was preventing the front brake from disengaging properly. Could possibly be caused by very badly worn disks and/or pads, ( causing the pads to come out of the caliper too much & getting misaligned ) , or corroded/seized caliper mounting, or some other problem with the caliper and/or its mounting.

    The job needs to be done - car is unsafe without it.

    It sounds to me like the symptoms associated with a piston being seized in the caliper, keeping the pads pushed against the disc.

    Replace caliper, discs and pads.

    I'm not sure what the "sea-side" thing is about unless these is evidence that corrosion has caused the piston to seize, in which case the cause is likely to be a failed seal, which has nothing to do with the seaside, but may point to the seal being damaged while changing pads.

    Gulp. Up to 300 quid. Obviously it needs to be done so I'll have to pay it. To me it seems as if it happened while I was travelling to work. I didn't notice anything untoward prior to that. Unless of course I didn't realise until this morning.Yes the car seemed sluggish and laboured and thats why I did notice this morning. The mechanic did mention a piston without seeing the car however when he did examine it he said it was the disks. Should this happen with such small mileage (only 55k) on the car?

    Repair caliper, replace discs and pads.

    ... Repair caliper ...
    It all depends. If the piston didn't cause damage to the sleeve in the caliper then it may be possible to replace the piston, the seals, etc. and repair the caliper as you suggest. But a full working caliper from a scrappy will cost €50 at most and it's probably going to cost more for the repair.

    Maybe you picked up a stone that got jammed between the pad and disk? Living by the seaside might mean the disk gets a layer of corrosion overnight, but i think all disks get that to certain extent, and it ribs off quickly without a problem. (But what would I know?)

    Nearly exactly as you mentioned above Foxt. The disks were rusty and the brake wasn't disengaging properly. Fixed now anyway. At a cost of 180e.
