Lexus LS 2007+ :: Grinding Noise When Braking While Cold
Aug 3, 2013
I just had new pads(ceramics, not sure of the brand) all around and new front rotors installed from a local shop that I trust. When braking while cold, there is a grinding sound and feel, I took the car back to the shop, they've acknowledged the issue, double checked their work, and are willing to replace the pads if it continues, which it has. Is there a break in period for ceramics, should I specify a different type of pad.

Loud engine grinding noise accelerating from stop when you first start the car? It is right after cold start, lasts 10-15 seconds until I get to 30-40mph. Engine sounds normal otherwise.

So my dealer diagnosed my 2007 Prius with a transaxle issue, but what bothers me is that it doesn't make the sound all the time. When I brake lightly, there is no sound and when I brake heavily there isn't either. It is only when I do a medium brake above 7 mph of course and around 20's mph range. I am hoping for something besides the transaxle...maybe a wheel bearing...anything.

2006 SAAB SUV AWD, Right front wheel rubbing/grinding. When cold, coasting and braking. Not continuous. It has completely died while turning. New tires all around. Had both front brakes replaced x2 in 2 years. Still rubbing feel in right front.

I have a 2007 ES350 with 85k miles. I've noticed that whenever the AC is turned on, there is an audible grinding/groaning type noise coming from the engine bay. If I turn the AC off, the noise immediately stops and returns as soon as I turn it back on.
I've also noticed that the noise only occurs when the car is in drive or reverse. If I switch to park or neutral, the noise immediately stops.
I had the serpentine belt as well as two idler pulleys replaced in hopes of solving the problem but the noise is still present. Any other troubleshooting I can perform to narrow down the problem?

My 2007 LS 460 makes a noise like a pump pulse sound during braking. When I step on the brake before coming to a stop there is no noise but once the car is 20 feet before coming to a complete stop at times you feel and here a pulse or pump or vale sound in the front engine area. Sometimes as I increase pressure on the break pedal a little harder you can feel and here a single pule and at times 3 or 4 valve or break pump sound. What might be going here? I am certain the sound is not coming from the wheel area. It is definitely under the hood. Could it be a faulty load sensing proportioning valve or booster?

I have a 2007 RX350 with about 243,000kms on it. I recently purchased this car and everything is great on it except one thing. As of late, I've begun to take notice that when I accelerate from a stand still (for example after stopping at a light/stop sign), a loud rattling/grinding starts and then as I pick up speed and change gears, it fades away. The sound is more rattling than grinding. As if there is a metal bowl with some smalls stones in it and someone is just shaking that. There is also another sub issue that I'm having. There seems to be a clicking noise every time I apply the brakes or even accelerate. The same clicking noise reoccurs every time I put the gear into drive from neutral. However, when I do that, there is only click as opposed to braking/accelerating, where there are many. I'm hoping this is all part of the same issue and not isolated issues.

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.

I've read a few posts about the Prius braking system. Just wondering what other owners have done when they experience the metal grinding noise and when brakes need to be replaced. My car has around 67,000 miles. I was planning to take it to a Toyota dealer, although prefer to find a certified Prius or hybrid mechanic at an independent shop.

I recently purchased a brand new 2013 Hyundai Elantra and I have noticed that I sometimes when I brake fast but not fully slamming on them from going about 60-80km I hear a loud grinding noise. When this happens the roads are dry so I know that it is not caused by slippery or wet roads.

Bought my Prius (2005, with 160K miles) about a month ago and since I've had it I am hearing a metal on metal grinding noise when braking at low speed. How loud the sound is depends on how hard I am on pushing on the brakes. One of my co-workers has the same model and said that his does not make that sound. Not sure if its just because it has after-market brake pads or something? This noise only occurs when braking at low speeds (below 10 MPH) so I assume its an issue with the front brakes.
Is this something I need to get looked at by the dealership? I had a local mechanic that worked on my old Honda beater take a look and he said that the rotors and brake pads looked new and wasn't sure why they'd make noise.

My car is making metal grinding noise when coming to a slow stop when you are stuck on traffic or going into your driveway. You can hear the sound and feel the sound.
I had this issue a year go and i took it to the dealer and they told me that i need to replace my rotors and my front brake pads.
A year later the noise came back and they told me that i need to replace my pads. I replaced my front break pads and a month later the noise is back. I went back and checked my pads and the pads were still new.
I only hear the sound when braking after driving in a heavy traffic or on a stop and go traffic. I don't hear the sound when i start to drive or driving in a non traffic condition.

I may be worrying over nothing but lately when I brake or accelerate I hear a grinding noise on my radio. I listen to AM. With my other vehicle it usually meant there was a problem somewhere.

My car was making a weird grinding noise when braking above 7mph. I did the neutral brake thing and seems to go away sometimes. The dealership said it needed new rotors and brakes, so I went ahead and did that with them, then called me to let me know the sound did not go away. Now they are stating my grinding noise is coming from the "inverter generator" which is what they said was the transmission. I am just curious why this goes away sometimes and if it's related to my previous issues with the car.

2004 Jetta GLI V6 24v 6 speed ... This started a few years ago, but it was happening in 3rd gear only -- therefore I avoided engine braking in 3rd gear all along. The noise was a pretty loud, noticeable grinding/spinning noise. 3rd gear while accelerating or maintaining gas worked and still works perfectly, smooth as can be.
Somewhat recently (6mo-1yr ago) all the other 5 gears started making this grinding noise, some more than others. 1st gear I don't really know because I don't engine brake in 1st. However, 2nd, 3rd, 4th, 5th and 6th (barely noticeable but still there) all make the noise. I now of course avoid all engine braking, however even the transitional steps between gears can be heard sometimes ... unless I perfectly match the RPM etc, but I'm just trying to get to work and back here ...
The car is still quite drivable, but with a major obstacle (pain in the ass) and a new clutch is probably around the corner -- I have 107K on it now. However ... a few years ago when it had 26K on it .. it didn't need a new clutch yet 3rd was still making that noise.

Recently I've noticed more that when we first start the hyundai in the morning or after sitting a while and we use the brakes it grinds/ squeals a little and then doesn't after about 2 or 3 miles. Is this something to get checked out or should I spray something on my brakes to lubricate?
My next step that I though of was to get a simple automatic car wash cause it's been a bad winter in Rhode Island and the street shave been flooded with rock salt. I figure that might cause some friction under the pads.

I bought a new 2013 Hyundai Elantra Coupe this past August and this is my first car.
My first concern was that Hyundai advertises 27mpg in city and around 37(?) for highway. I acknowledge the fact that Hyundai recently had to lower their mpg estimates for some of their cars and provide reimbursements but however, these reimbursements are for 1-2mpg difference. My car after more than 6 months is still only getting about 14-15 miles on a casual drive in the city and only about 19-20mpg combined and about 24-25 on the highway! I am only getting about half the estimate for in city! I do not drive aggressively. In fact I am a pretty safe driver since I am a new driver and cautious about everything. I am also using premium gas on my car. I called the dealership I got the car from and they were trying to tell me about the reimbursement program which I already knew of... The reimbursement based of the 1-2 mileage difference is not what I want. I want to fix it and get close to the estimated mileage as I can. What is the best way to go about doing this?
The other issue is that sometimes when I hard brake, my car makes a loud grinding noise. My dealership's service center said they could take a look at this. I was mainly wondering if there is anything I should be concerned about for this?

So whenever I brake while reversing (and rarely while moving forwards) I hear this odd grinding noise coming from the front left wheel and can feel it through the brake. Im not a petrol head but I decided to replace a wheel bearing hub myself recently to save money. I am pretty sure I reconnected the anti lock brakes correctly though I doubt it's that. My brakes are good.

I have a 2008 Toyota Yaris Hatchback with only 60,000 KMs.
I have been having a lot of problems with this cars ABS and brakes. For a few months now, the ABS Light and "!" will come on and off throughout my drive to work and home. Also, sometimes when I hit the brakes it makes a LOUD grinding noise and when I'm holding down the brakes the car doesn't stop as fast, it kind of like skids. Now, I've noticed that this noise only occurs when the ABS light is OFF. When the ABS light and brake light come on, NO noise what so ever.
I've gone to multiple mechanics and replaced almost everything you can name for brakes (pads, drum, rotor, etc.). I've also tried replacing the ABS sensor wires, but still I am experiencing the same problems. It's really frustrating because the noise only happens sometimes, and of course it never makes the noise when the mechanics in the car with me.
I've made a video of the noise it makes, you can check it out here ......
