Screeching Noise When Braking My Mazda 2

Changed my brake pads a couple of months ago from a big servicing and repair chain. The car developed this issue right after. I went back there to get it checked. All I was told was that the brake pads form a layer of dust which causes it to make that noise. Has anyone had similar issues after they have changed their pads?

Edit: Anyone knows a reliable mechanic around Parramatta, NSW?

    No… That sounds like improper install or pads worn out already. The screeching is an actual indicator to alert you to replace them.

    You might get a bit of squealing if they're super brand new or haven't driven in a while and slightly rusted etc but should be gone after the third traffic light.

      The screeching is MOST COMMONLY an indicator the pads are worn. However, there are other causes and if the pads are new, you should have an expert check it out - not the one that installed them if they tell you it’s ok.

  • Probably cheap crap pads. What sort of car? Did they replace rotors as well?

    • Mazda 2. Nah, just the pads.

    Don’t mess around with brakes. If they are making noises that they shouldn’t, go and get them checked by a professional. Certain systems on cars should not be guessed at, brakes is one of them.

    Go somewhere else to check!

    If it's a 991 GT3 with carbon ceramic brakes then don't stress. It's normal.

    You usually need to make sure you bed in brake pads properly as well, that might also be the issue.

    Possible they replaced the breaks on one side, but not the other.

    When only replacing pads you can sometimes get noises due to the pad not matching the worn surface of the rotor. The noise will sometimes go away within a few thousand km until both surfaces are mated properly but not guaranteed.

    Best option is try a bedding in procedure as most mechanics don't bed them in as well as they could be.

    The noise might not go away which doesn't mean the pads or workmanship is bad.
    Majority of the time you can get away with just replacing pads with no noises.
    The only guarantee to fix the noise is to replace rotors aswell which is one reason why its usually recommend.
    Rotors are heat sinks so a new rotor will always perform better than a old rotor.
    Even relatively new pads and rotors can be noisy usually due to driving behaviour or not bedded in properly though not common

    When I had my car I went to a mechanic at Midway shops in Denistone.

    Rule NO.1 Most mechanics are liars especially if they got the Ta/apprentice to do it and they never checked over the work.

    You might have a piston locking up on a wheel causing it. Jack each wheel up do they spin freely? Has one wheel got more noticeable black dust around the rim?
    Look at the receipt did they machine or replace the discs? Can you see the discs are they shiny or dull looking if they're shinny then the mechanics only changed the pads if they're a dull mat looking you either have new or machined discs and that's good.

    If the pads wearing thin it's the steel wear indicator grinding against your disc. Screeching noise to me would sound like an aircon belt slipping

    Happens when my wife is in the car.

  • Just pads and not skimming or replacing rotors is generally a half-baked repair.

    The noise could be as simple as lack of cleaning and lubrication (when fitting the pads) of those surface that have metal touching metal.

    It could even be the pad material or they left out the shims or there is material build up on the rotors
