Brake Clunk - My experience

I took my (03) X today for the brake clunk - basically, braking after direction change results in a loud clunking noise - also took with me the invoice that someone had posted on this forum about the shims they got installed.

here's what they said:
- every MDX has it.
- its normal.
- the shim set is a factory part, ALREADY installed in every mdx, so it doesn't make sense to install it again, and there isn't enough space to install ANOTHER one.
- he Moly-coated my brakes (all four) as a one-time warranty gesture - said it will take care of the clunk for a few months, but it will be back once the coating wears off, and there is nothing that can be done about it.

My questions are:
1. Is there ANYONE on this forum who DOESN'T have the brake clunk?
2. Is there ANYONE on this forum who was able to get rid of it for good?
3. The person who got the shim set installed - was it not there in your X earlier, or did they just replace it with a new shim set, or did they install another one OVER the existing shims?

Thanks for your resonses.

Hi MDX350:

___Our Brake Click developed after ~ 4000 miles if I remember correctly. It was not like I didnít expect it sooner or later but unfortunately, it came way too soon

___Good Luck

I don't think I have heard the "clunk". I guess I'll know it when I hear it.

Just took my 01 X to the dealer today...

Once again I was told there is nothing they can do about it. I even printed out the work order someone posted on here to show the dealer. He stated the part were from a Honda Odessy and only for the rear brakes. He stated the brakes already come with shims.

He told me the bottom line is that Acura is not addressing the issue because it does not affect the safety of the vehicle. He stated that almost all the MDX owners who purchased at the dealership (Springfield Acura in NJ) all have the same issue.

Bottom line is its a design flaw. And the worst part is Acura is not even owning up to it.

I dont think we're asking too much to get a form letter from Acura explaining that its not a problem. They wont even do that. Hell for a $40k+ car I dont think its asking too much.

Even if nothing can be done to fix the problem I think in the spirit of good customer service Acura should send something out to the customers if only to give us the impression that they know about the problem and they care.

With all the new SUVs on the market Acura should take care of its customers if they expect future customer loyalty.

Right now I feel that for the $$$ I paid I really didnt get my $$s worth. Dont get me wrong, I like my car but from a value standpoint you really should get more than fake plastic looking wood and clanking brakes. The Honda Pilot has almost every single feature of the MDX for several thousand $$ less. Definetly a better value for your money.

Next time I might have to consider Lexus, Volvo or Toyota.

MDX350,

My MDX developed directional change brake clunk after 4,000 miles also as posted by xcel. Like you, I reported this to my dealer during some other warranty work and got the same results. Yes, I know most of us paid $40,000+ for our MDX's...and yes the Acura engineers should have thought more about this "brake clunk feature." In the end, you just start to live with it.

When the pads are replaced you can bend the new pad to go tight against the caliper. This will make the noise go away for good. You can even open the calipers without replacing and bend them by hitting them with a punch bit and that will take up the slack and no more noise. My Acura wouldn't do this until the brakes need replacement, but Manager stated this will fix for good. Out of factory they use the shims which wear down, they should use a punch and snug them in at the factory to make it right.

That punch technique sounds like such an easy fix. Why didn't Acura do this in the first place to eliminate brake clunk?

Agreed, Acura probably doesn't want to slow the folks down on the assembly line.....even though it would take less than 5 minutes a wheel!

Any negative long-term effects of this brake clunk on the brake life?

It's not a problem, it's a FEATURE...

I took my MDX in for this same thing a few weeks ago and got a long laborious lecture on why it is a bad idea to try and fix it.

Acura is not the only car company that has this, um, feature. Grand Cherokee's do it too...as do many cars with rear disk brakes. Other companies have tried to stop the pads from shifting, but it causes the pads to either drag on the rotor and overheat the brakes or drag on the caliper...and it still shifts, you just can't hear it as much. Neither of these things are good for your brakes, and according to my service manager it will shorten the life of your brake pads, and potentially the rotors too. I acted skeptical, so he went to great length to show me on cars that were in the garage bays.

Anyway, that is why Acura isn't trying to fix it. They feel their design provides the best wear on the pads, rotors and calipers and any modifications to fix the knuckle cracking noise will just screw up the brakes eventually....causing more warranty repair.

So, my pads are still doing their knuckle cracking every time I change directions and stop. But, I am not going to risk putting in a repair that will cost me more money in the future.

Mine has brake clunk

Mine has brake clunk that started around 5000 miles. Not a big deal to me though.
