  • [Corsa D 2006-2014] Rattling noise

    Im going to be honest and say I am not the best in the world with cars & i figured here would be the best place to come for help before I get ripped off in the garage. But whenever I drive across speed bumps or just in general driving really i have a strange rattle coming from the front of the car. My friend seems to think its in the passenger footwell but to me it sounds more back right of the car, but he's probably correct. I am already going to have to folk out £250 for new front brake pads before my next MOT according to the garage & if this is going to cost a lot it would be coming near the point of not being worth it financially. It doesn't cause a problem with the car its just annoying and i don't want it too progress to something dangerous. Any help or advice would be great ).

    Hi Welcome to the form

    Its not easy to accurately locate rattles on the move. A rattle I was convinced was at the rear on my Yaris turned out to be a broken front spring.

    The most likely source of the rattle on the Corsa D are the anti roll bar Drop links. These are quite cheap and easy to replace. You may even be able to do it yourself. Look it up on line.
    You may be able to detect them rattling by grabbing hold of them and giving them a shake , or use something as a lever to see if there is any excess play in the joints. But be careful, never climb under a car supported only on a jack . If replacing the drop links doesnt fix it, there are other possibilities, but may need an experienced mechanic to locate the problem..

    £250 for brake pads sounds a lot. .Unless the quote was from a main dealer (main stealer) who are notoriously expensive. Much better to use an independent garage with lower overheads. I think for that price they probably mean the front discs need replacing.(together with new pads) Are the discs scored or rusty?

    Replacing pads , and changing discs are also possible for an experienced DIY mechanic but not really a job for a beginner.

      Thank you for the response! Yes, I was mistaken and sadly it does state discs as well. But, it was from a main dealer, so may be able to get it cheaper somewhere else.

        Its best to avoid main dealers. Pretty much any garage will be able to work on brake pads and discs (maybe not complex ABS problems etc) . For more complex vauxhally stuff try and find an independent vauxhall specialist who generally employ vauxhall trained mechanics. (main dealers employ lots of trainee mechanics , and sales executives, car washers etc etc)

        A possible downside is some mechanics ,stop and steer establishments etc will use the cheapest pattern parts available. Whilst these may be ok you might prefer to have Original equipment (OE) quality brakes . They will probably fit better parts if you pay the extra ,but might grumble a bit (or claim theirs are great) if they have the cheapo ones in stock, but have to have decent ones delivered . As a very rough Guide cheapo brake pads might only cost them £10 a set, and two brake discs £30 for parts. Whereas they might be able to get decent OE quality , such as Brembo for maybe twice these prices. (I have brembo discs and pads on both my cars . I fitted them myself)

        Incidentally was it a main dealer who said you needed new discs? Whilst in no way do I want you to drive on sub standard brakes a small amount of scoring and rust may have no material affect on braking and might still be able to pass the mot . To some extent the tester can use his expert discretion of how much scoring and minor rust is acceptable. A main dealer, might be more critical then elsewhere. , But discs do wear thinner over time, and have a minimum acceptable thickness which is not open to discretion. But if the discs are deemed acceptable, maybe the pads are still ok as well. These too have a minimum thickness that is 'measured' (or expertly 'estimated' ) If they are nearing their limit this may be shown as an 'advisory'

        But its not worth taking risks or penny pinching. If the pads need replacing and the discs are borderline it makes sense to get them replaced at the same time. Much of the dismantling work is duplicated. Equally you should always fit new pads when fitting new discs, even if the existing pads have little wear.

          Hi there,

          If you're looking to but new brake pads then it is worth investigating Halfords brakes4life where they offer free replacements of pads after paying for initial set. I've not tried them yet but been recommended by friends. Also, I'm not paid to sponsor them lol

            I did not know about this scheme, and I can see why someone learning that they might one day get free replacement pads might recommend it. But how many have actually received new pads totally free of cost?

            Most people only need new pads every 30K - 60K miles . The major condition of the scheme is that you agree to them repairing any 'faults' they find during their inspection of the brakes ,hydraulics and cables. This wont be free . Their word is final. No free pads without paying for the other work. Whether it really needs it or not. They might 'find' things like dirty calipers that need cleaning ,discs with slight rust or scoring that they will assure you need replacing (even though they would easily pass the mot) ), renewing brake fluid earlier than the manufacturers recommendation etc.

            'Free' safety checks are a very emotive subject. How can you object to safety checks and brakes kept in tip top condition? They might occasionally find a real safety issue. But there is no such thing as a free lunch. It costs them fitters time, , (once its up on the lift for inspection the extra time and cost of fitting new pads is fairly small. ) Even if its a genuine loss leader to attract customers they are hoping to generate extra work.

            Personally I have enough experience to clean my own brakes, and change my own pads and discs if necessary so I tend to steer clear of 'free' checks. But they can be a good idea for many . Many similar establishments offer 'free' checks, but the extra perk of potentially getting free new pads makes this better than most. .

            There are fair use exclusions, so boys racers cant expect to have their pads replaced every 10k miles
