Dealing with garages that cant fix a problem?

[FlamBango]

Ok so im getting a very loud noise when i press the brake pedal. I assumed it was the calipers sticking. The discs and pads are 2 weeks old. The old ones were warped to hell and juddering badly when braking , so put new ones in. Im assuming that the vibrations knackered something else around the brakes over time.

Fast forward to now. I have taken the car to a garage regarding the noise when braking. They think its the discs and want to replace them at quite a cost, the fronts. I'm not convinced this will fix the issue as the discs are new and there is no new juddering, still cutting them in and driving very carefully! So my question is what comeback do i have if the noise is still there after the work is done. Get my money back? Get them to fix it properly and take the cost of the new set of brakes off? I'm not an overly confrontational person so its not too easy to stand there and argue Up until now ive been really happy over the years with the garage, so its frustrating that they cant diagnose this issue right away.

If they can prove there is a problem with the 2 week old discs then surely you will get a refund form the manufacturer? Assuming it's a manufacturing fault, if it isn't then they need to fix what's causing the fault to occur.

yeah thats fair enough. If the new discs are fine with a couple of days driving then i will assume they were the issue. I dont know how they would provide evidence though. This whole area is quite grey and trading standards dont really say a lot about this sort of situation. I know theyve done good work for me before so no reason to think they wont now, they just dont seem 100% it will solve things. Ive always assume replacing discs / pads was one of the easiest jobs that could be done so struggle to see how a new set could make this noise when you brake. Anyway, fingers crossed it will be solved.

Back up...

Firstly what "very loud noise" are you getting? Describe it if you can. Do you get it when you brake or do you get it all the time? Does is it louder when you are braking at higher speeds?

Secondly, did you fit the parts? If so, what brand parts did you fit? Are they the correct parts?

Thirdly, what make/model/year car is it?

Fourth, are you getting juddering from braking or just "very loud noise"?

I haven't touched it.
It's a metallic whine, loud, when you softly apply the brakes, stays noisy briefly when you lift off which made me think of sticky callipers. They think the disk is warped but I don't feel any judder at all.
