    Annoying brake noise!

    Since fitting my big brakes, I've had a loud click/knock noise when slowing.
    The calipers are secure so I know it's not that but I've pinned it down to the pads.
    Looking at the part of the pad that comes through the caliper, connecting to the retaining spring (remember member "expoliceV70's thread about the spring flying out due to there not being a clip coming off the pad) the metal blades/clips/things appear to have been stretched, as if somebody has tried removing the pad without unclipping it from the spring. The spring appears to sit a bit further out from the caliper than it should as a result and when I bashed it back in with a screwdriver, the noise went away for about 3 miles and now it's back.

    Would I be right in presuming I need new pads? I've looked at the pad and un-stretching the metal bit doesn't seem to be an option.

    All input welcome guys but reading this back, it looks like I've answered my own question.

    If there is a click/noise when braking, there must be some movement and give when the cars weight transfers, which is not what we want!!
    So yes, you know what needs to be done!!

    Martin. The spring clips stop any movement, so new pads here we go

    can you not remove the pad. heat up the steel fixing part and move the bits wear they should be when its cherry red. that way it wont spring back like it dose when its norm temp. not to loost i guess.

    The head of the rivet is 50% damaged so if I start messing about with it all, it'll probably snap off.

    Is it possible to heat and manipulate spring steel like that?

    yes its ££££ible. but as youve said if the rivet is damaged your going to have to let the heat do the work. think of it as warming up plastic. it gose soft so you can work it with out it being brittle. metal is the same.

    its only 1mm plate steel. will take no heating up at all. the pads them selves wont even reach the temps they would under hard breaking. im sure martin wouldnt do anything to risk the saftey of his family.

    I can put the plate and friction lining in a water bath and heat the tabs with no fear of affecting the compound (it's supposed to be able to deal with heat and moisture, after all) but I don't want to go messing with it as the chances are, the bloody thing will snap off.

    I've found some pads in euro carparts for 28 quid but a make I've never heard of so not sure.

    Says "for 336mm disks" on the website but I don't like buying brands I don't know, especially when it comes to brakes and the like.

    Bl00dy hell Martin!! Now you have mentioned this, I am hearing a clicking noise as I apply the brakes.

    Have you tracked down exactly what it was and have you got it sorted?

    I have just put new pads and discs on, so am scratching my head now.....

    I'm 99% sure it's the stretched fins on the pads causing the click. I just ordered a set of mintex pads from that very nice chap called Jamie at PartsForVolvos at a nice price. Hopefully, they'll arrive tomorrow and I'll get them fitted by the evening.

    Have a look at your pads and how the retaining spring connects to the fin that pokes through from the pad to the outside of the caliper, make sure it's locked in properly.

    I'll take pics when I fit my new pads, for reference.

    Is everything as it should be with your new pads Martin? I am going to strip my brakes down and inspect them this weekend, so would be good if yours are OK and is a simple fix for me!!
    I get the click noise most noticeably when I am shunting back and forth in a car park, as if the retaining spring on the caliper is being pushed forward and back when the pads bite the disc. If I go forward and brake 4 or 5 times forward only, then it does not happen, as if the spring has been pushed as far as it will go on the first brake application. Is that how it was for you?

    I only ask as I happened to be in my local dealer yesterday and got chatting to the head technician. When I told him of the symptoms and what I thought they were, he told me that it was probably something MUCH worse. I don't even want to think about it, so I hope you have fixed the problem with new pads!!!!

    PS, you posted some pics somewhere, but I can't find them now!!

    click

    The loud click has gone (I really should've got some footage for reference) and the new pads are lovely

    When I park, if I reverse and brake, I get a slight click from both calipers (it is only slight), I'm presuming it's just the pads shifting a little as there's about 0.5mm of "slop" if you wiggle the pad about. It then does the same quiet click when I go forward and brake.

    The retaining spring won't be moving about unless the "fin" from the pad is damaged/worn, even then, the spring will only shift outward and stay there. It won't cause any noise at all but will allow the pad to rattle in the caliper, giving you a loud click when the brakes are applied.

    Take your pads out mate and have a close look at the fins on the outer pad. Take some pics if you can.
