Brakes on a 2.5 Vectra

    Recently took my 98 Vectra in for its MOT, according to the testing centres
    result I needed new brake pads on the rear for the MOT. The garage who did
    the MOT replaced the pads for me, according to them the rear discs were fine
    and did not have to be replaced. Now when I brake from speed I get a noise
    which can only be described as an air brake (not so loud tho) on a truck
    from one of the back wheels. When i looked at the disc I could clearly see a
    gouge mark all round the disc were the origional pads had worn in to it. I
    asked the garage about the gouge and was told that the discs were fine and
    that the pads had not worn in properly. I left the car with the garage so
    that they could trim the new pads better to fit the discs. This happened
    about 1 month ago and the brakes are still making this noise. Am i right to
    insist that the garage replace the pads and discs (I would be willing to pay
    for the discs) but the labour and new pads are down to the garage? BTW I
    know its the brakes making this noise because it only happens when braking.

    The pads are VX original or 'compatible' replacements? Sometimes the cheap
    one don't cope with the disc (noise, whistles, rattle, etc).
    It belongs by the components used to make the pad braking material.
    Replacing them (both!) with original VX spare parts should fix.

    But would the gouge in the disc make the problem worse, or is it down to the
    pads itself, as you are saying?

    If the gouges in the discs are made by different sized / shaped pads, maybe.
    It's quite normal that some mechanical parts 'get used' each one with the
    other, during a long time.
    Some of the pads' material permanently wields with the discs (don't forget
    that they can become VERY hot under some circumstances!), and using a
    different make/model of pads may develop strange behaviour of the whole
    system, with a different chemical composition of the old pads' loose
    material wielded on the discs and the new pads' one.
    With high mile-aged cars it's better NOT to change make and model of the
    spare parts, it is known to be a major source of problems.
    Even with the electric parts (bulbs and fuses), and (weird but absolutely
    true) the screen wipers!
    This is NOT definitely a hidden 'promo' for original brand replacements, if
    you like to use cheap spare parts it's better to get your car used to it
    since it's brand new (pretty much impossible to do, if you want to stick
    with the maker's warranty) or almost as soon as the warranty expires.
    But, as I've told before, once you've choose a make/model of parts, stick to
    it. It's better.

    braking.


    Light scoring of the discs is usually OK if they're within spec
    otherwise. Maybe they put the wrong size pads on?!

    AFAIK, a car shoudln't fail becasue the pads are worn, only that what's
    there isn't good enough to pass the brake test.
