brake pad uneven wear

Well then the pads are made wrong for the car and the garage should order a set of quality pads which are manufactured to the correct specifications. If you bought them yourself then a reputable garage would refuse to fit them if they needed to be filed down.

I imagine they were doing, what needed to be done, nothing wrong, sometimes they don't fit, due to rust, or maybe they were just removing dirt.

Takman's rght on this. If they don't fit because of rust or dirt then you clean up the rust & dirt (usually in the caliper channels rather than the pad). Wire brush and brake cleaner should be all that's needed, if you have to resort to a file then something's wrong!

If it were me I would clean them myself, it is not rocket science. If I couldn't or that did not work, I have BOTH calipers replaced.

I would and replace the clips and slide pins, but if the Op has never worked on brakes before and he's got a known problem probably better to take it to a garage, or only attempt it if he's got a knowledgeable friend who can show him what to do.

Plus, being the rear, will need to think about the handbrake mechanism, might need a screw retractor tool.

it was supply and fit from the garage. I didn't supply.


what other reasons could there be apart from what's mentioned? because the calipers been greased twice, the pads been removed and re fitted twice.


I read somewhere it could be the hose pipe that operates the caliper? should the garage be automatically checking this?

It's most likely to be the caliper that is sticking and needs replacing but any decent garage should be able to tell you if this needed to be done.

I also hope you didn't pay for them to clean it twice? If after one clean didn't work then they either didn't do it right or cleaning it wasn't the solution, so no need to pay for it again.

Just a suggestion, based on my experience over the years: possible that the wrong pads were ordered. Was it an automatic or manual gearbox? Pads made for auto box cars are usually a bit thicker that those for a manual box car of the same model. (apart from gearbox spec) This is in recognition of the fact that an auto box vehicle needs to use the brakes more often, to slow down and cause a change of gear.

its a manual. but the previous pads had the same issue on the same side so having the wrong pads fitted twice will be a huge coincidence.


I will take it to the garage and get it looked at again.


I take it rust on the brake discs wont have this affect as no one has mentioned it to be a possible cause?

Geez, go to a proper garage and pay a bit more for a decent mechanic to work on your brakes.

The pad carriers need cleaning hence the tight pad and consequent uneven wear. A good mechanic will take the carrier off and clean them before fitting new pads. It's such a common thing these days.

Filing the pads? lol dear oh dear.

Salubrious is right: failing other suggestions being relevant, there is obviously something wrong with the operation of the caliper, preventing the piston going back into the caliper, or the slides going far enough back. Get them properly checked at a mainstream garage.
