Toyota - Prius :: 2007 - Front Brakes Sort Of Grinding And Rear Grabbing
Apr 10, 2015
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?

I have an 2007 Toyota Prius and in the mornings, especially if it is humid or moist outside, my brakes grab badly during the first couple of stops....it's bad enough to make somebody run into the back of me. When it happens, you will also hear a screeching noise coming from the (sounds like ) rear brake, passenger side. I have taken the car to the local garage twice and they found nothing wrong. I have taken it to the local Toyota dealer 3 times and likewise, they found nothing wrong either.

Two weeks ago I took my 2004 Prius (with about 165,000 miles on it) to the dealership because of problems with the rear (drum) brakes grabbing (sometimes hard enough to lockup one of the wheels). Their diagnosis was that they were badly out of adjustment. They "cleaned, adjusted and beveled rear brakes" which fixed the problem, but it returned this morning. I should also mention this dealership had "cleaned and adjusted" the rear brakes twice before over the last couple of years.

About a year ago, the rear brakes became very suspectable to moisture and started grabbing. After a few stops the grabbing would subside, but I could still feel the rear brakes engaging a little earlier or more than the front brakes (the rear-end of the car would hunker down a little). So I replaced the rear shoes, the old ones had about 90K on them, not worn real bad and had plenty of life left. I made sure that when I installed them to clean everything, put a skim of silicone brake grease on a couple of the friction points and set the adjusters down so they would be able to auto adjust to the right setting.
The grabbing didn't stop, so I've lived with it for a while and finally got around to replacing the front brakes on the assumption that maybe since they were old that they may not be stopping the car as much as the new rear brakes were. Didn't work, in the back of my mind I'm wondering if there is possibly something wrong with the master cylinder and the balance between front and rear brakes is off. I'm going to go clean the rear brakes again today and crank the adjusters back to see if they adjust to a better position this time around. The drum and disc surfaces are in good shape and color.
Can the master cylinder get its balance messed up?

What causes grabing brakes in the morning OR when wet???

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.

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.

I have 2003 F150 SuperCrew 5.4L XLT. For past month or so, have been hearing metal rubbing sound and had shakes in braking - as well as a "grabbing and pulling" sound near brake pedal - very aggravating to say the least. Weird thing is the grabbing and pulling sound only happens under 10 miles an hour or coming to a complete stop. (The grabbing sort of sounds like the sound the ABS makes when hit really hard)
Yesterday I had brakes and rotors replaced - mechanic said front rotors were beyond turning - very bad. 135,000 miles on truck. Felt more comfortable until I pulled out of shop and when I applied brakes, had the same grabbing/grinding sound, but no pulling. Went back to mechanic and had him ride with me to hear sound, and he is stumped.
Knew it was safe(r) to drive since new pads/rotors installed, but when I got up to 55mph and barely touched the brakes, the steering wheel began to shake violently - but no sound/grabbing from brake pedal area like I get when I am 10mph or under. Really at a loss right now.. What's going on?
Truck is a 2WD, also hear some thump thump thump sounds from front left tire, which are only one year old, but tire man said that was from suspension arm or something - nothing to worry about he says.
Some people have said "bearing" or "hub" but when brakes were replaced, the bearings were repacked...is this the same thing? Is the current problem safe to drive with? I do not take vehicle out of the county - just to work and back and hunting on weekends.

My 2011 Honda Civic makes a grinding / squeaking sort of noise when I start it after it has been sitting out in the rain - either for several hours or overnight. The noise seems a bit like the noise when you crank the car but the engine doesn't start. It happens after rain or a snow, so it would seem that moisture is getting into a place it shouldn't. The dealership checked it out and couldn't find anything wrong or anything that would prevent it from starting. They also told me that this noise might well go away after the first oil change - that the additives in the oil now are suppose to seal things.

So I have a 2012 Sonata with about 80k miles on it. I bought it used a few months ago. It has recently started having issues with the brakes.
When the car is cold and I start driving, every time I push down on the brakes they will do a quick grab after a few seconds. Sometimes its a slight grab and other times its a jerking grab. After I drive 10-20 miles or so and it warms up this goes away.

When I am driving, regardless of the speed at which I am traveling or the weather conditions, etc. The car arbitrarily surges, making a sort of grinding sound. I have to quickly tap the accelerator to stop it...a real problem if traveling in rush hour traffic, for example, so as not to run into the car in front of me. I have mentioned this to the folks who service my car but, naturally, it never does it in the shop.

I replaced the pads and rotors on my 1989 toyota camry yesterday. Took it out for a test drive and all appeared to be OK. I did not bleed the brakes, but did have to remove a small amount of brake fluid after installing everything.
On my way into work this morning there was quite a bit of grinding noise coming from the brakes. The noise was not consistent, happening both while brakes were depressed and also when not in use. It also would go away after a few minutes and didn't always happen while braking.
I'm thinking the piston may be locking up at times, but don't know. I'll also throw out there that this is my first brake job. I did follow my Haynes manual and don't think I did anything wrong.

We have a 1998 Toyota Corolla with 170k miles. The brakes are squeaking and grinding often. In Feb. the front brake pads were replaced, but the noises continued. In May, they replaced the front pads again, within a week the grinding and squeaking continued. Finally, I took the car in late July and had the mechanic drive the car around. He said the back brakes were making the "grinding" noise and the front was squeaking. He said it was "cheap brake parts". When he looked at the brakes he said the back brakes needed adjusting and may not be working as well, therefore making the front brakes work hard. This caused the front brakes to get hot and develop a glaze. He adjusted the back brakes and scratched up the front brakes. The car was fine for about 2 weeks or so. The sounds have gotten progressively worse and I refuse to drive the car. The brakes seem to work, but the sound is so terrible like something is loose, or off and scraping metal. We have used this mechanic for years with a recommendation from our neighbors.

Just bought a 2010 Toyota Rav4 about 2 weeks ago. It rained the other day and the brakes made a grinding noise the first time I braked after starting the car but didn't make it after that. Did it again the same day, still raining, but only the first time I braked after starting the car. I have a 30 day guarantee on the vehicle and need to know quickly if the brakes are bad or not.

Yesterday morning, as I backed out of my short driveway, I felt a grinding and then felt a thunk on the passenger side when I applied the brakes. Why would my new Venza[~5401 miles] have this? The dealer didn't feel it during a drive and couldn't find anything wrong with the brakes on inspection. The dealership claimed it was due to rust. I don't buy it. Why would new brakes rust and why would Toyota make brakes that rust?

I thought I'd be free of problems having bought a new Toyota Rav4 in Jan. In June, with less than 3K miles, my husband had a (BIG) fender bender (turns out his meds made him blank out, he was driving at 10-15 mph) (and he is going on 80). Repairs cost over 3K, but I was able to drive it to the dealer. Soon after I got it back a month later, I started hearing a brief grinding noise under the accelerator, at speeds of 20-30 mph. Mostly after I took my foot off the accelerator, once or twice after I took my foot off the brake. This noise sounds like brakes grinding, appears very sporadically and briefly. I took it to the dealer and of course they could find nothing wrong, said everything checks out. They said to bring it back when it's doing the noise. Which it does maybe once a week, for a second or two. sheesh.What to do? I actually want to start all over, I do not want to drive with my ear to the gas pedal. (My husband now only drives in town!)

My car came back from the shop yesterday with new brakes and pads and seems to be making some odd noises, both at low speeds and while breaking. I called the shop this morning and they said that this sound was normal for awhile but to come back in a week if it persists. Is this sound advice, or should I be driving my car right back to the shop?

My rear brakes are grinding so I am preparing to replace all pads and rotors. Any special tools or procedures from when they did theirs? Do the rotors have retention screws? Do you have to use a special tool to push in the pistons?

I've got an 03 Camry (211K mi.) with front and rear disk brakes. I have a pulsing/grinding sound from the rear brakes. I think the pulse is from the run-out of the disk/rotor. Took it to a Toyota dealership last year and they pulled apart, cleaned and lubricated the parking brake assemblies on both sides. Brakes ran quiet for about 3 months and then the noise came back. When the climate is dry, it makes all kinds of noise. When it's humid (above 80%) or raining it's quiet. It still stops good and there is no pulling to one side or another, so I figure my calipers aren't leaking.
I bought the car used a little over 3 years ago and don't know when the last brake job was done. I was going to replace the front and rear disks and pads and inspect the calipers for cracked cups or seals. I was talking to an old school mechanic and he said something about opening the bleeder line(s) when I compressed the cups or I'd damage the ABS control. I looked at my manual and it said nothing about this. I'm not looking to replace the ABS controller because of a silly mistake on my part. Looking for info about cracking the bleeder when compressing a caliper??

I use a bottle hanging like an I.V. drip to flush the Brake Fluid in all my cars. I can pump all the old fluid out, as well as the air. My Superduty 7.3 has a good solid brake pedal after the flush. It seems to me the rear brakes handle 60% of the stopping load. Its been like this for so long I'm not sure if it's ever been different. i then go to a gravel or wet road and test the rear abs, and it seems o work, but definitely has a squirrely feel. I did some strong pavement stops with speed, and it stops, no skidding. Is that the way it should be?

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.
