Prius (Gen 3) :: Grinding Noise From Front End When Applied Brakes At U Turn
Apr 9, 2014
Coming to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.

1950 cadillac - standard drums on all 4 corners.
I put new wheel cylinders on each drum, and replaced the drivers front hose, as it was clogged. The passenger side I left because it works and doesnt leak. I've cleaned all the brake surfaces, shoes and drums, and bled everything.
When I brake, and only when I brake, the front right makes a grinding noise and the car pulls to the right.
I tried tightening the star wheel today to bring the shoes inward in hopes that would equalize brake pressure up front, but when trying again today, I got that grinding sound still.
There is no scoring or gouges on the shoes, drum, and the inner and outer ball bearings seem fine - round chrome balls with no discoloration, no gouges on the spindles. Granted I don't drive this far at all, especially now that I have this grinding.
How can I really tell if its the ball bearings? It only makes the grind when I am on the brakes.

Is it just me or is this an ABS thing? during a snow storm i was going about 25mph and had applied the breaks and started making a grinding noise... if it is the abs how are you suppose to work with the response time for a quicker stop.

I noticed yesterday a sound, like a grinding sound, *sometimes* as I apply the brakes to stop. I'm at 68k. The noise only happens when the brakes are applied so I suspect there is an issue with my brakes again.
Some BACKGROUND info: At around 60k (or 8 months ago roughly), the front pads were replaced after the brakes were squealing and a pulsating brake pedal when stopping. The pads were replaced by a dealer. In addition, both front/rear rotors were turned at the same time. Rear pads had 40% at the time and were not replaced.
Some weeks later the pulsation came back and I went back again and they machined them again. For this current issue I was thinking about taking the car to someplace local (not a dealer) and getting a free brake evaluation of what is going on.
I'm also concerned that all this machining the dealer did to eliminate the pulsation may have decreased the life of the rotors and perhaps they need replacement now.

I have started hearing a noise with my brakes. First thing in the morning when I back up and apply the brakes, I get a clunk or pop noise from the left front wheel. It will pop again once I move forward and hit the brakes. It only does the noise one time when I first apply the brakes in either direction. Once the brakes have been used out on the road and are warm, there is no noise when changing directions. I've had this noise in another car I used to have and it was caused by the aftermarket brake pads not being exactly large enough and there was slight pad shifting in the caliper. Being this is a new car and has the OEM pads, I would hope there would be no pad shifting or movement in the calipers.

My wife told me she was hearing a squeaking sound coming from the front end of our 2006 Prius (90,000 miles) along with a noise when she applied the brakes.

Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.

2008 Passat Komfort Wagon with 34,500 miles. Started to get grinding sound when I applied brakes, which diminishes as I drive. Thought it was rust, but sound is very loud and sounds just like pads are gone and digging into rotors. The brake warning light is not on.
Dealer told me rear caliper was closing unevenly and recommended service---not covered by warranty of course. When I picked-up car same noise as before. The service manager told be that the car was just washed and the rust built up in the last hour---I could believe some built-up, but the sounds made my teeth ache. When we went for a test drive the noise got quiter, but was still apparent. The SM told me this is a "normal" noise. I have had many cars with disc brakes, dating back to a 1960 Jaguar; none have made this "normal" sound.

Over the last 2 wks or so I have been hearing grinding noises out of the right rear brake. 1 day it sounds like it was metal on metal. Think is just all the road salt catching between the brake pads?

Here's my issue, after a full break job my right front brake began to grind. Curiously it wouldn't grind initially after breaking soon after start up. I could go on and slow break for quite a distance, but soon after a hard brake or just slow breaking long enough the grinding begins. I've taken the car back to Firestone three times and even after a few adjustments or cleaning the problem persist... I've starting to feel bad for Firestone and embarrassed to be holding on to this 99 Chevy. I can't continue to drive this small car that sounds like a MTA bus while braking.
But I digress... I did notice, purely by accident (or it may be a mere coincidence), a few times the ABS light came on and during those periods the grinding was less abrasive. This leads me closer to believing the issue is with the caliper.

When I gently apply the brakes at slower speeds there is a single "click" noise. This happens every time. I took it to the dealer. They said it was normal. I am just trying to find out if indeed it is. Do other people get this click when they apply the brakes.

I have a grinding noise coming from what I believe are the front brakes. It happens when I apply the brakes and sounds like the brake pad is worn out and there's metal-on-metal contact but when I checked the pads, they are at 80-90% (rears have about the same amount left). I hear it the loudest just before coming to a full stop, from about 20 mph down to stop. I thought it was caused by rust on the brakes but after I wore off the rust, the sound is still there.

Driving in snow, braking in this car routinely handles poorly and brakes make a loud grinding sound. It sounds like the front brakes. I just had a brake job from a trusted dealer. I read the thread here on the Honda Accord that reported the same sort of brake problem. The issue is the brakes, NOT tires as that thread suggests. Braking strength is greatly impaired under these conditions. I am very apprehensive about driving in snow, and ready to trade in what is otherwise a fine car.

My mom has a c-3, today while she was out, pulled out of a parking lot at slow speed, went to stop at the traffic light and all she hear was a 'grinding' noise and had no brakes. Luckily she has thinking ability and used the parking brake to stop. She pulled off when able but then the brakes were fine. I'm a gen III driver.

I have a 2007 Prius with 130,000 miles on it. I plan to trade in about a year, maybe a little less. I have noticed my brakes grabbing. My mechanic says that the front brakes are sort of grinding and the rear brakes are grabbing. Both are worn, the rear brakes to about 30%, front brakes to 60%. They also say they will probably last out the year. Should I put new brakes on to be safe and to be able to sell the car with new brakes, or should I just wait it out and trade it in with worn brakes?

Just noticed this tonight. While making a left turn, I had the blinker on and had the brakes applied and noticed the indicator on the instrument cluster was blinking. Once off the brakes, it took it a few seconds for it to resume blinking.
When I got home, I checked to see if the right signal did the same and it did. I also checked the rear lights and when the signal is on and the brakes are applied the light does not blink nor does it brighten up like they're supposed to when the brakes are applied, it stays dim as if both the blinker and brakes are off.
I did a quick search. I have not checked any of the bulbs or wiring, but I'm thinking it might be the turn signal switch/ lever. What the problem might be?

So, last week I got my transmission replaced and they also had to replace the CV axle because it was damaged beyond repair when the Transmission self-distructed. They drove it after all the repairs and said it was driving fine, just that it had a belt squeak.
On my way home (30 min drive) about 10 minutes in, still in the city, my brakes start making a grinding noise and sort of a thump thump thump when I brake which sounds like its coming from the passenger side front, it makes me really nervous. It doesn't sound like any brake grindy noise Ive ever heard before and it wasn't making any brake noises before it broke down. (On a side note: it also made a weird noise maybe the first 3 times I drove it after getting it back and I turned the wheel hard to back out of a parking space, that used to be when I heard the belt squeak but I haven't made it squeak since I got the car back.)
Everyone I talked to said it sounded like it needed new pads so tonight I bought new brake pads and rotors for the front and got everything taken apart. The rotors didn't look bad at all, just some light surface scratches, nothing deep, no warping I could see, and the brake pads look almost brand new. I did notice that the inside brake pad on the passenger side was missing its little metal plate that is usually between the caliper and the pad, so I went ahead and replaced all of the brake pads hoping this lost metal plate was the issue.
I also turned the rotor by hand on each side while the brake pads were off and the only difference I could notice was when turning the passenger side one it made a little more noise almost like it was loose.
I got everything put back together and drove around the neighborhood with my boyfriend in the car to listen, the grinding noise was gone and it seemed to brake really well (never got above 30 mph.) However, on my way to return the rotors to advanced auto (45-50 mph) it started making the thump thump thump noise but without the grinding, still on the passenger side. I can feel it in the gas pedal and now it not only happens when I'm braking, but also any time I let my foot off the gas pedal. The only time I dont feel/hear it is when I'm accelerating.

2005 Lexus RX330. 98K miles. 2 year intermittent problem. When apply brakes the front end shimmies until car completely stopped then go again & all is well until at some future time it happens again. Dealer checked twice & private repair checked also. Nothing found. Tires re-balanced & rotated several times. Newer tires with no issues. This is an INTERMITTENT problem. The rotors have been, new pads & spring installed.

my 99 s/w 2 started making a squeaking sound coming from the front right wheel area it goes away when I apply the brakes? is that one of those built in warning features to let you know the brake pads are getting low? the brakes have 86,000 miles on them.

Buddy has a problem on his '03 F-450 cab and chassis. When he turns on a turn signal, everything is OK...but it goes out when he applies the brakes. Also, the brake failure light is lit up on the dash, despite the brakes being fine. These problems happened at the same time. I'm think a ground, but not sure where to look.
