Creaking/Groaning Noise during low speed braking (2023 CX5)

[bizkitgto]

I recently had my front brakes and rotor replaced (stock OEM parts) two months ago (due to loud brake noise), and I still hear a noise from the front of my 2023 CX5 while braking. The noise comes during low speeds, usually under 10 mph, and almost always when coming to a full stop. The sound is not an obnoxious loud, high pitch squeak or squeal that you typically hear from brakes, this is more like a groan or creek, almost like a trumpet sound. I also hear a similar noise while shifting from park into reverse or drive. I hope it is not transmission issue too! This is driving me crazy!

Any thoughts?

They may not have put the anti-squeak pads/compound on the back of the new pads or cleaned everything well before installing new pads.

Anti-squeak pads? There were no such pads on my 2023.

Some aftermarket pads come with them.

The stock pads on 2023 CX5 are KY01-33-28ZC-MV, which are made by Akebono and I believe they are semi-organic. These aren't the good ceramic Akebono's.

I overlooked that OEM parts were used. My bad. It could still be due to lack of cleaning or anti-squeak compound.

Mazda does not use or recommend any grease be put on the pads, but you do on the areas where the metal clips attach.

How noisey are your brakes?

They started squeaking on initial reverse out of the driveway recently. They don't do it any other time. 2023 with 8000 miles.

those are NOT "stock pads", those are value line pads that dealers sells, which are a lower priced product different than what came from the factory... they are spec'd and made to a different standard, so don't be surprised of fitment (seen it myself) and noise issues

you can either get real aftermarket akebonos or go back to true stock and see if that solves the problem

yes they do, and they sell mazda branded grease (expensive here, cheap in japan) for that reason

but since the OP used unknowningly value line pads, the shims that come with them are inferior to the true OEM pads that came with the car... so, it's not a surprise to me that it made noise, whether the shims were greased or not

to me, noise is only acceptable from performance pads, due to more aggressive compounds... unless those value line pads stop harder (cold and hot) than the OEM pads, I would go back to get the pads warrantied

What I meant was Mazda does not use any grease on the back of their brake pads at the factory. And if you do some research online, the consensus is that it is not needed. The lube we are talking about is around where the clips go in.

Also, I could not find Molykote locally, so I used the little silicone grease packets from Advance Auto Parts.

 

[TheMAN]

the shop manual (what I copied from) says to grease the back of the pads, and the OEM shim kit comes with the grease too... any grease that may have been used in the factory will be very too little to notice by the time you need to replace the pads

"consensus" is that the grease helps makes the shims more effective at reducing the high frequency vibrations that causes break squeal

I replaced my pads at 3500 miles and there was no grease on the backs.

I agree with greasing the metal clips.

I had the same symptoms recently after having the dealer replace the front brakes on my 2017 CX-5 GT. I took it back to the dealer and described the symptoms. The service desk person claimed it was an industry wide switch in brake pad material that was causing the issue (an explanation I took with a very large grain of salt). They “resurfaced brake pads to remove glazing” (as listed on the invoice) for free. Noise returned a week or so later. I hadn’t had time to investigate more, but based on the other posts in this thread, I looked at the part numbers and sure enough, they used the cheap pads. Based on what I see at parts.mazdausa.com, it looks like the higher quality pads are part number K0Y1-33-28ZA, listed at about double the price. Not sure if I should take it back to the dealer and have them put those pads on, buy them myself and have somebody else do it, or have someone else put on aftermarket pads (I’m sure I could accomplish it myself with help from the Interwebs and some tools, but I don’t feel like messing with it). Won’t be going back to the dealer for repairs in the future. Up until now I’ve been satisfied with their work.

Edited to add “front” in the first sentence.

make them do it... they misrepresented the job that you paid for with misleading substandard parts

Based on some research online, I have heard the combination of Brembo rotors (coated) and Akebono ceramic brake pads keeps things quiet. I have yet to try this, so I cannot confirm. This may be my next experiment. I hope my problem is not caliper related...
