Lexus LS 2007+ :: Brake Performance Rotors - Mild Grinding Noise Or Rough Feeling When Stopping
Oct 7, 2011
I installed a set of Brake Performance rotors ( slotted ) with premium ceramic pads and have had a bit of strange stuff going on from day one. When I first got them installed there would be a mild grinding or rough feeling when stopping. It got better over the first couple of day but was still there. I also notice a loud whirling or humming noise when I stop from high speeds. I called brake performance and they saids that it may be that the ceramic pad is to hard for the system. It sounded a little odd. The weather in AZ finally hit 77 yesterday so I have been driving with the windows down and have been noticing more of the grinding sound even when the brakes are not pressed.

So I'm new to the all time awd car thing. I came from a 4x4 truck which 4x4 was never engaged on pavement or in tight cornering. When maneuvering my is250 awd in tight spots ie. parking lots and the front wheels are at full lock in either forward or reverse there is a slight binding/grinding feeling or faint noise. Is this normal on an awd car or Lexus specific??? Did a quick search and didn't find much about this issue. I'm pretty sure its not tire rub.....stock set up.

I have a 2005 F-250 4x4 and recently i noticed a grinding noise while driving and then when I come to a stop I hear a clunk and the grinding stops. It sounded like it came from the driver side wheel so I changed the wheel bearing assembly. About 3 days later it started again. Now it sounds like it's coming from both sides. I am at a loss. The hubs are unlocked. It's hard to describe the sound but to me it sounds like 2 gears with a large chain rotating on them. I hope that made sense. The clunk can be felt in the brake pedal.

Last June I took my 2001 Audi A4 off the road since I bought a more fuel efficient commuter car but I wanted to keep the Audi in the family until my oldest son started driving. That day has come and I'm making the car drivable again. I pulled the battery over the winter and kept it on a Battery Tender. I put it back in over the weekend and the car started up up and runs just fine. The only problem is that the rotors are extremely rusted and make a horrific grinding noise. Is there anything I can do to remove this rust? I assume I can just grind it off with the brake pads but that can't be good for the brakes which, if I recall correctly, are fairly new.

Experienced excessive brake noise? Driving to work this morning and noticed the car was not stopping as normal and brakes being very loud. Did a quick check and found my driver's rotor looking like this...

I have 325 miles on my Touareg. When I drive, especially during the first 15 minutes, I can FEEL something unusual happening in the engine through the steering wheel. Example... when I am stopped at a light, I can feel something like a "hum" or something experiencing resistance in the engine. It's not always continous. I am not used to feeling anything like this through the steering wheel when I am stopped (based on my other cars). This feeling is more pronounced when I turn. It seems to vanish when driving a straight highway after 15 min. I can only relate it to "feeling" a hmmm.
I have never owned a 4WD vehicle so I don't know if this is normal. I wish I could describe it better.

But I'm still getting a grinding/clunk noise and general loose feeling from the front end. The only play I can feel is when I grab the u-joint/knuckle and pull up and down on it. I also noticed the seal at the end of the axle shaft tube is not there on 1 side... would this lack of seal cause the looseness?

I noticed the front brake pads were touching the rotors when I was painting the brake calipers. I had my e-brake engaged and in park. I'm assuming the e-brake only brakes the rear wheels because the front rotors were still movable. Although the car still rides fine but I'm not sure if this is normal.

08 ES350 with 52k miles has a grinding sound in reverse. Brake pads were inspected - ok. Suspect that parking brake shoe is worn. Any tips on teardown/replacement ?

I replaced my warped front brake rotors a couple thousand miles ago and all was fine but when I went to swap over to my snow tires, I can see that the outer part of the rotor has been rubbing on the caliper bracket. This is happening on both front rotors. Could my new rotors be too thick or something?

i have with my Treg. Occasionally, like once every two weeks, when I am slowing down to almost a standstill, i suddenly hear a loudish grinding noise that seems like it was triggered electronically. I seem to think it happens when the auto box is shifting from 2nd to 1st before the car comes to a standstill, but not every time. Obviously when I took it to the dealer it did not happen!

I performed brake maintenance today with my brother on my 2010 corolla CE, my front rotors were warped and my pads were used ( and also uneven) and I replaced both front rotors and pads.
The install went smoothly, my brother changed a couple of brakes sets and knew what he was doing and showed me up.
Took it for a spin, the brakes work very nicely ( i bought the ceramic wagner bundle ) but theres a slight grinding noise when driving, like the pads are touching and rubbing a bit too much on the rotor, but the driving is unnafected. Also, there's a sqealing noise coming from either side when you turn only.
Braking itself produces no noise whatsoever, only when you turn that it squeals.

I replaced my pads 3 months ago. Now I have a metal grinding sound (not squeaking). The mechanic says I need new rotors, and he will resurface the pads. I know I can replace the rotors myself; but do I need to resurface the 3 months old pads? If so; how will they resurface them?

Just thought I'd ask, I was at the dealer last week and while there asked them to take a look at my brakes because they were making a slight screeching sound but only when first applied when speed was slow.
They said it all looked good but that the sound I was hearing was from grooves that had been etched into the driver's side front rotor. I find it hard to believe that my rotor would have grooves in it after only 21k miles, considering I don't track it or drive it aggressively that would have caused that.

I'm having a vibration feeling while driving. The dealership has replaced both lower control arms, bushings, and the right side drive shaft. They have told me that it is caused by my rims and tires. So I purchased new rims and tires and that has not fixed it.

Two weeks ago I pick up our 08 460 SWB , with 24,300 miles on the car ...
I noticed today while in park standing and waiting for my wife to come out the nail Solon ..the car had this very mild tremble / shake ...and sounded like a belt under the hood was loose .. Something like a rotating fan sound loud but not that loud to make a big stink out of... When I drove off and came to a stop sign I pressed the breaks and RPM's went from 1,100 to 1,300 and back down when the car was at full stop??

I have a 2007 Honda Civic with about 46,000 miles on it. I purchased the car "certified used" about 1 1/1 years ago. For the past several months I've been experiencing a grinding/crunching noise when I apply the brake in reverse. I've taken it to a Honda dealer and they more or less told me that it sounds like something could have been wrong with the brakes. They ended up telling me they couldn't find anything wrong and that my brakes are fine. I've called the dealer to see if they could look at it again, but now my car isn't under warranty and they'll charge me to look at it. What could be causing this noise? At this point in time it's more annoying than anything - I'm afraid if I let it go it might end up hurting something in the long run.

So, got the 20 K miles service done last month on my 2012 Passat.
Recently I noticed that when I press the brake pedal to slow down, it seems to work fine. The brakes "catch" the rotors, there is a clear "grip" to the rotors and the car responds pretty fast to start slowing down. However, when I did a brake check to stop the car, I notice that when I press the brakes hard, they don't "grip" the rotors as hard as I would expect past that initial grip instance. Seems like their grip is not "catching" the rotors. As a comparison, my other car (6-cy, disc brakes front and rear) does maintain that grip. Am I missing something in this? Is the behaviour of the Passat's brakes expected?
How often does VW do break flushed based on their service schedule?

So I just bought a 2004 Ford Focus. I did not drive above 15mph when I tested the car due to the lake effect snow that was occuring. Now that I own the car I have noticed if you try to stop going over 20mph the car starts to stop but last second it lurches forward a little bit. There is also a grinding noise that sounds like its coming from the back and a loud vibration that sounds like its coming from underneath the middle of the car. I'm trying to figure out if it is the brakes, tires or a leak in a brake line (those are all things my dad said it might be).

I'm getting sick of having my rims getting dirty after one hour of driving because of all the brake dust that the OEM pads give off. I keep hearing from shops that ceramic brake pads are not only more quiet but will put out much less brake dust. On the other hand, Lexus is telling me that if I do that, I will forsure damage the rotors but I really feel like they just want me to keep the car stock which is why they're saying that.
Are ceramic brake pads a bad idea with stock rotors?

I hear a grinding noise from tire area when in motion and when stopping and happens only intermittently. I have taken my 06 chevy uplander to 2 auto repair shops and to a chevy dealership repair shop now and all three say they can't find anything wrong with it. shortly after, the noise happened again but now when it occurs the display screen reads... Service ABS system and service Traction system... when i turn the engine off and back on again the warning is no longer there unless the noise occurs then will read both again.
