Clunk from rear on braking?

Alext · 10-24-2008, 05:07 AM

What is causing the clunking sound from the rear when you brake (with a sharp press on the brakes)?

Anyone else get this?

I also notice a slight rattle from the transmission when coming off the clutch quickly and engaging a gear while the car is in motion. But I think this is normal as I remember my '01 MX5 doing this. (only audible when no AC is on and windows up).

Alext, i get the brake/rear issue too.

Alext · 10-24-2008, 05:16 AM

Kris, I find that reassuring that I'm not the only one. I initially thought it could be the pads moving in the caliper, but it doesnt sound like it. It really sounds like something to do with the rear suspension.

Kris · 10-24-2008, 05:22 AM

Agree, ive no idea. Only does it now and then, extremely slow and as you said, with hard pressure

Alext · 10-24-2008, 08:33 AM

Yes, only at extremely slow speeds...for example when I am coming to a stop in my garage.

Is it a different sound than the toolkit sliding around? That is annoying when it clunks around.

Alext · 10-24-2008, 08:10 PM

Na it cant be the toolkit.

Hi guys, I had this too. Had a friend get their head near the rear wheel to find the source, it's the pads moving and hitting the caliper. The noise is amplified in you garage, if you brake in reverse and the move forward and brake they will shift back and forwards (the pads) and smack into the surrounding caliper metal.

Alext · 10-25-2008, 07:19 PM

Thanks Swift. I did a test last night also...I again suspected it was the pads shifting around because I noticed as you said above it only happens in one direction once.

Kris · 10-25-2008, 07:42 PM

Cool! good find. Alext, did you test it and found the issue?

ANyone also have an annoying squeak on their sunroof when its open? grr drives me NUTS

Alext · 10-26-2008, 03:21 AM

Kris, yes I am pretty sure it is the pads that are moving around causing the clunking. Pretty normal. Or as we say on the Lotus forum whenever a strange noise is heard in our poorly insulated cars 'TADTS'...They All Do That Sir. (usually the reply you get from a dealer).

WAY · 10-26-2008, 08:49 AM

I have a cure for your problems guys because i don't seem to have this problem. Get yourself aftermarket front pads and don't use the factory backing plate. You will hear so much clunking noise that suddenly it's impossible to hear the rear ones. Lol

I thought it was the dog leash smacking the bumper a la Clark Griswold :biggrin:

WAY · 10-26-2008, 06:08 PM

Prof knows what I am talking about because he has been in my car and have heard my non-backing plate front pads lol.

cuizhuoyi01 · 02-27-2009, 03:16 AM

I had the clunk noise too. sound like something not tight and hit something.

matt · 02-27-2009, 06:18 AM

Common noise.

Its comes from the tank's.

The thing that makes this noise is the "tankmeter" that meassures your fuel.

You wont notice the noise when your tank is 3/4 to 4/4 filled up.

edgab · 12-28-2009, 03:02 AM

i also heard this clunking noise from my rear right when braking at slow speeds. i'm positive it's brake related because when i hold the handbrake, i can feel it at the handbrake lever.... any fix to this clunking? should i worry about it? thanks.

Shawncube · 12-28-2009, 06:35 AM

I had the same problem, it's the fuel tank and mine was replaced under warranty after replicating the noise to a technician.
Hope this helps

What's the problem with the old fuel tank? What's making the clunking sound? Thanks.

Shawncube · 12-28-2009, 11:18 AM

As already said it is the 'tankmeter' or 'fuelmeter'. Mine was loose so the fuel would knock the meter and would produce the clunck sound. It will not make the noise if you fill all the way up.
Hope that helps
