Hi

I had new mtec discs and pagid pads fitted to my car last week.

When I wind the window down my car sounds like its on a rail road.. as if the brakes are scraping (well they are )

From what I can tell a portion of the disc already looks to be corroded (as attached ) or the pads are touching..

Any advice ?

Pads are not touching where it is corroded.

I had the same problem on a Landrover - are the pads stuck in the carrier, or are they free to move? If they get stuck, they can do this. Also worth checking the wheel bearing.

As above the pads aren't making full contact with the disc. Often an issue if the carrier and slider pins haven't been cleaned properly and subsequently greased. Take it back to the fitter and ask them to do the job properly.

Something definitely wrong there.

Incorrectly assembled or they aren't the right discs for the car.

Whoever has done that job needs their arse kicked. Was it an apprentice and the work wasn't checked? If that was an experienced mechanic he would never touch my car again.

Thanks for the responses.

Is it also possible that these are non oem discs and pads thus need more bedding in time ?

Nope, shouldn't do.

Check the wire spring clip that holds the two parts of the caliper together on the outside.

I have MTEC dimpled and grooved all round, almost the entire front disc is swept by the pads. The rear pads sweep from the outer edge to just past the inner dimple, a small portion of the inner end of the groove is not swept.

All the best

Those pictures look like the outer edge of the disc is rubbing the caliper and that is causing the noise you hear. It is also fairly obvious that the pads aren't sweeping the centre section of the disc like they should.

Please can you jack the car and take photos with the wheel off. Pictures of the disc side on and picture of the outer edge of the disc where the disc goes inside the calliper.

If you are in the AA or RAC I would ask them to inspect this work. It isn't easy to see in your photos but to me something is very wrong and I still suspect incorrect discs for the car or something really odd with the way they have reassembled this.

Where are you based? If you are near M4 between Swindon - London (I travel a lot) I'll come and have a look for you and point out what appears to be wrong.

Hi kandlbarrett.

Thanks for the offer much appreciated however I live in West Midlands.

It's going to another garage tomorrow to resolve an oil leak and clutch issue (they fitted new clutch and did oil change last week ...) so will get a second opinion . I'll see what they say and post back on here.

Interestingly there is no sound coming from the passenger wheel, just from the drivers side. The sound also does not stop when applying the brake. It suggests something is in permanent contact with the disk.

One thing I just noted is that if I go onto eurocar parts the height for standard discs is 43.5 mm. The discs on the mtec website have a height of 44mm. Would this be an issue ?

Have you had a look at the spring clip on the calipers?

You can probably see it clearly without taking the wheel off.

I just had a look. Can't really see the spring you are referencing . There is the silver clip which holds the pads in but can't see a spring ? Nothing is touching the caliper visibly from the front

If the garage value your custom they should let you have a look with them and point out what is wrong. Some, for Health and Safety reasons, won't let you in the workshop but if you are escorted that shouldn't be a problem.

That small difference of 0.5mm in disc height won't be the cause.

DavidC has a point about the spring clip. Incorrectly seated and the calliper won't sit correctly so it is a very good candidate for being the cause and a simple 10 min or less fix.

Can you take a pic of the other side and post please?
