What’s up everyone, I have a 2000 Acura TL 3.2. 130,000. But theres a light metal scraping sound coming from the right passenger side. I had the front break pads and right wheel bearing replaced 2 days ago because it was recommended by my backyard mechanic. Yet the sound came back after disappearing for 1 day of driving . It normally makes the sound after I accelerate over 20 mph and when I take sharp right turns...what could this issue be?

 

Welcome to the forums.

Since this is a topic/technical issue which will require replies, and not a "New Member Introduction", this thread has been moved to the model specific forum.

 

Check the heat shrouds behind the brake disks. They bend easily and when too close to the disks will make the noise you describe. You can bend them away slightly with your fingers.

If it were a bearing issue, I would be suspect of the LEFT one since that's the one that takes the load during right turns.

 

 

let us know what you find

 

+1 on the brake shields. I bend mine back every time I do my seasonal tire changes; I mean REALLY bend them back, otherwise I would get a grinding noise when I turn.

 

 

If thats the case then you have a sticking caliper, least thats what it sounds like. If you have access to infrared thermometer shoot each wheel and determine temp to see which one is sticking.

 

Hey, is the sound coming continously for you, or more as a pulse? I just did my front rotors and pads, and my front drivers side wheel is making a pulsing mild scraping sound.... so I'm thinking for my case it's likely not the shield.

 

Hey Arkady, when you did the front brakes, did you, by chance, examine the (slider pins)? I recently had two different noises, coming from the left front, on light brake application, both a clicking type noise, and a rubbing type noise. Turned out, the bottom slider pin was dry, causing the caliper to drift, creating the noises.

 

I definitely did not check those for dryness! Will generic grease work there, or should I get fancy and get some Honda-specific stuff?
I'll take a look at those this weekend when I have time to lift the car up again.
