Noice while applying break

F

I am encountering strange noises while braking.


A local mechanic inspected the vehicle and found the brake pads and rotor to be in good condition, indicating a potential axle-related problem. Nevertheless, a Mazda dealership inspection concluded that the rear brake pad and rotor need replacement, with an estimated cost of $760. My car is a 2020 CX5 with around 60,000 miles. Could anyone please advise on the possible cause of this issue and whether it is worth having the repairs done at a Mazda dealership?

Please find the noice video attached

60,000 is not unusual for replacement of rear brakes and rotors. In fact that's pretty good unless all your driving is highway then it's about normal.
I had to replace rear pads around 35,000 miles.

Would this sound be caused due to rotor issue. I had my maintanance done recently from another mazda dealership and they told me that no issue with rotor or pads in the multi point inspection. I am bit worried that even after changing rotor if the issue would still continue
 
What exactly is happening when the noise is produced? Car moving, reversing, speed, you pressing brake pedal?? That's a weird sound.

When pressing break pedal. One weird is when i start the car and drive for sometime it do not cause any issue. After driving 5 to 6 miles and then break applies i get this sound. Once it starts it continues throughout till i hapt and start next day
 
You may want to find a repair shop that specializes in brakes and suspension, usually not a Mazda dealer. That sound may have nothing to do with the brakes, only that the sound is originating near
one of the wheels. When you had it in the shop did they check the calipers to make sure one was not getting stuck? That could possibly explain the sound.

When you get to the bottom of this come back and report what it was.
 
Maybe have a shop (dealer or whatever) put the car in the air, enough that the wheels are off the ground. Then have someone "drive" it while it's on the lift and have the mechanic listen to the rear wheels to figure it out. You can also spin the wheels by hand while it's on the lift and see if anything makes the noise.
 
This is their multi point inspection report. Before taking to mazda dealer i took to local mechanic. They were mentioning something about the axle and joints. But to check that they need to remove all and that would charge me with 400$

$750 now for rear brake and rotor replacement...every time I see some one quoting a dealer price for one of these jobs it gets higher and higher, seems like on a monthly basis. I paid less for a set of new tires last year. For comparison, a dealer quoted me $450 for rear brake replacement 2 years ago.

Had my rears done at the dealer back in Aug. $210.78 out the door although they did not replace the rotors, only resurfaced them.
 
Very strange sound indeed. You said you paid $230 for a diagnosis right? Was that from Mazda or an independent shop? In any case, if they diagnose the issue, they should be able to explain what is causing the noise, not just tell you what needs to be replaced. Ask them to explain what's causing the noise, and ask them to show you if possible.

The $760 quote from Mazda is ridiculous, but that's usually because they are buying new OEM parts and their shop rates are likely higher than an independent shop's rates. If you decide to go with Mazda, ask them what happens if you pay the $760 and your car is still making that sound. You will likely have to eat that cost, which is unfair.

I would be very hesitant to pay the $760 without a legitimate explanation of what is causing the sound and why new components are needed. It's entirely possible that your brakes and rotors are perfectly fine, and it's some other unrelated loose component. They could book you in for brake caliper and rotor replacements, but just tighten up the noisy component and not touch the brakes, and nobody would ever know once you left the shop. It sounds unlikely, but some of these dealerships are really that bad.
 
Does the noise happen on smooth road when braking?
Or, does it only happen if you are braking and hitting bumps?

I ask because my Explorer had a noise in the rear that was only present when braking and hitting bumps. Turned out to be one of the control arm bushings (~ball joint). Only made the noise when braking and hitting bumps, didn't make noise any other time. I diagnosed it myself by pushing/pulling on the wheels. I was able to see the bushing moving and could feel the clunk.

A good shop should be able to give you a pretty good idea of suspension noise without disassembling and should have provided that with the original diagnosis.

I agree with @sm1ke - I would want proof of cause before forking over a bunch of money to repair.

If i fix it from them they will not charge for the daignostics. They gave a quote of 720 now for rear plate and rotor replacement and also for engine filter replacement. And if issue reoccur they will daignoize it free is what they told

That's highway robbery. Not knowing your location it should not cost more than $400 for rear brakes and rotors. I'm assuming you're in the US. If not then pricing may be in line, don't know.
As far as engine filter, that's a $20 part (or less) and you can do it yourself in 5 minutes with no tools.

What they mentioned as an issue is that it is caused due to a groove worn in to rear rotors and caused damage to rotors and pads

If that's the case and you're sure that's the problem then shop around for a rear brake job. Did they ever put it on a lift, remove the wheels and show you the damaged pads and rotors? Should be pretty easy to see once the wheel is removed. If that's the cause of the noise then either pay the $720 or go to another brake shop. I'm assuming the $720 is for both rears, not just one. If it's just for one then that's extreme highway robbery.
