Prius C :: Clump Sound When Take Foot Off Brake Pedal Quickly
Jun 25, 2012
When I take my foot off the brake pedal quickly, like after a stoplight has turned green, the brake pedal makes a “clump!” sound. I have looked at the pedal mechanism and it is for sure coming from that area. It sounds as if a rubber bumper should be there, but is not. When I take my foot off more slowly, no sound comes from the area. Is this something I need to put on my 5K checkup list? My car has 1700 miles on it now.

After driving in the rain and starting the car again after a few hours (as in starting the car again after work, or starting it first thing in the morning) the following happens: As soon as I release my foot from the brake pedal to go into "drive," there is a "thunk" sound from the rear of the car as well as a lurch. A soft "thunk" may have a soft 'thunk" sound, but a louder thunk will have a pronounced lurch/jerkiness from the rear. The car drives OK and has no problem with braking when I apply the brakes.
It happens only after driving in the rain. The dealer says the sound and movement are the normal result with disc brakes wearing off the rust on the rotors. Other wet weather concern (happened once): while driving in a couple inches of snow, the brakes began to grind and eventually failed to bring the car to a stop. Dealer rotated the rear rotors (due to uneven wear, although I had the car only two weeks at the time) and installed new rear brake pads. He said grinding brakes on an Elantra are normal in rainy, snowy, and dusty conditions. Is my car really safe to drive? Is there a problem? I'm considering trading it it as I don't feel safe. It is an otherwise OK car.

My friend has a prius and had her brake pedal sawed off modification. Funny cause she says that her foot is always slipping off the brakes now. It was always a bogus fix, to fix nothing caused by errant drivers.

I have a "05" Prius problem that I'm stumped on. I have 165k miles. I am the original owner and have maintained this car really well and it really runs incredible. I just started to hear a strange new whirring/winding sound coming from the front when driving. When accelerating it goes quiet. When I let off on the gas it starts whirring. Between 40-45 MPH if I let off on the gas it will whir but then when I drop below 40MPH it does it intermittently. It almost sounds like it is attempting to slow the car down . I've looked over the forum and other sites and hear about other sounds like this (ex: A/C motor), but nothing that matches my symptoms. I can say this, it in no way affects the performance of the car, just very annoying. If it is serious I would like to jump on it right away and try for 200K .

I drove my 2005 Prius 2 hours and parked it for 5 hours. No problems on the trip down. I got back in it and it started up just fine. I was sitting in the parking lot with my foot on the brake (hadn't moved yet) and the following occurred:
The brake pedal seemed to push back on my foot
The red exclamation point illuminated
The yellow exclamation point illuminated
The ABS light illuminated
The VSC light illuminated
The red parking brake light illuminated (not shown)
All of these lights point to the skid ECU. It seems like my skid ECU is toast or something called the ABS & BA & TRAC & VSC Actuator is an issue (never heard of it but I see it connected to the skid ECU). I did a visual check of what I could and everything seemed in order. I pulled a bunch of fuses and I didn't notice any that were blown. (I didn't pull them all but will tomorrow)
After not finding anything, I drove back home. As expected, I had no regen but the bigger problem was that I had no power assist on the brakes. A few times I actually did skid and the car brakes really bad without regen or power assist. If it was raining or snowing I could definitely see a hazardous situation.
I'm kind of at a loss here. Tomorrow I'll pull the kick panel down and see if the skid ECU is getting power but I can't think of anything else that would cause this situation.

I have just replaced the front pads and discs on my car. a 2000 115 tdi sport. Now I have a problem - the brake light is not always going out when you take your foot off the pedal. And it feels like the brakes are binding, but when you jack it up the wheels are all running freely ...

I just bought a 2013 Passat SE 2.5 about a month ago. Since driving it home I have noticed that the brake pedal sort of sticks when I let my foot up off it. It doesn't happen during hard braking, just normal to light, especially when I'm riding the brake in heavy traffic. When I lightly press the pedal in, it feels like something is sticking and again when I let off it has the same feeling and it will sometimes not come up with my foot, but it rather slaps/taps the bottom of my foot while returning to position.
I took the car back to the dealer to check out and of course the service tech didn't feel what I felt. So the let me drive a loaner Passat, same model, and I felt the SAME sensation in its brake pedal. At the time I just chalked it up to "that just must be how these are", but it's kind of annoying and I don't totally feel it's right. What is causing this?

I have a 2002 F250 4 whl drive 7,3 L Diesel with auto tranny. It refuses to run unless the foot is on the brake pedal. I have replaced the brake stop switch and A L L the fuel filters. It will start at times and idle near perfect and at other times it will start and then stop. When it does idle there is not a skip but when you put it in drive it shuts down unless you keep your foot on the brake. I think I only have 2 hairs on me head I have not pulled out

There is a low buzz sound when I have my foot on the gas pedal. It doesn't seem to effect acceleration or anything. At first I thought it was a wheel bearing but the noise disappears when I remove my foot from the pedal. The Sebring has 65K miles on it.

ABS, Traction, Brake (red & yellow) bulbs in.
ABS not working
Reduced brake efficiency
Heated brake disks
Regeneration charge indication doesn't go to left side much. But slightly charges battery.
ABS fuses ok in engine room
No vacuum sound in brake pedal
But faster brake actuator sound (every 5sec stop 2sec sound) on stopped ready mode in P. Engine not running.
Bit history;
I had brake light fuse blown. But not knowing was pressing brake pedal hard to start / goto ready mode as display said. So after replacing fuse, had the traction bulb on. After it was reset. Everything was fine. Apart from increased vacuum sound in brake pedal.

I have another small issue with my 2004 Prius. I just noticed yesterday that the second I very lightly depress the brake pedal, a little clicking sound is made down below. It sounds like it might be coming from the brake pedal itself or somewhere underneath the hood. It's only when I depress the pedal slightly and it makes pretty much the same sound when I release the pedal. I just had a 5000 mile service done to the car and there were no issues then.

I can press on the brake pedal when car is off or on and there is a kind of quirky sound made. I can hear a pump sound and then a squeaking or quirky sound. It happens every time I press the pedal when it is stopped, either on or off.

I'm having issues with my prius that are baffling me and I was hoping some of you smart prius masters could lead me down the correct path, I traded in my dodge durango to get 2 cars, a Lexus which runs great and then a 2001 Toyota Prius, The problem im seeing everytime I drive the Prius is no matter how fast im going when I release the gas pedal to quickly i get 3 warning lights (a triangle warning, Check Engine, and a Car with an explanation mark) the car will then only take off to a max mph of about 15-20....If i pull over and restart the car the warnings go away after about 4-5 times of turning the car off and on, I plan on taking it to the dealership.

I've never used "foot parking brake" on any of my cars before. The one I have has a standard automatic transmission when I put in "park" the pin inside the transmission locks it.
Do I just press the "P" park button or press the "foot parking brake" first?

Purchased a 2006 prius not too long ago with just over 100k miles.
I like the car, I average about 42-44 mpg. It is really for my commuting. The question I have is it seems like my brake pump runs all the time. When I take my foot off the brakes, it runs, when im in a drive-thru, my battery drains super quickly, however if i put in park instead of leaving it in drive while in the drive-thru, it does not.
My only thought is there is something wrong with my brake pump and the way it drains batteries.

I have 2005 Prius, 53K miles on it. Bought it as used car few months ago. It has been running great since then.
Since last few weeks I have been hearing a soft beep every time I take foot off the brake. Today I had my windows down while driving and I realized that the soft beep is actually a loud noise like squeak or beep. I can hear a noise every time I take foot off the brake (NOT when putting foot on the brake).
Anyone can standing near the car or other car drivers at red-light can hear the sound too.. This happens when- the Car is in D, I take foot off the accelerator and press the brake (to slow down or complete stop) then take foot off the brake.

Whenever I stop the car I push the P button, and the push the foot parking brake, then I stop the car with the start/stop button. Yesterday I started the car, and forgot to push off the parking foot brake. I put the stick on D and then I started to roll, after two seconds I saw the red lamp on the dashboard telling me there's a problem, so I check and to my surprise I saw that the break was on.

In the last couple of months I have noticed my '10 Prius III begins to roll forward or backwards about a foot depending upon which drive mode I select without releasing the brake. So here's the normal scenario I get in the car have my foot on the brake, turn it on wait for the ready beep/light, my foot has never left the brake or lessened pressure but not so much as to trigger the hill assist, I shift into D to go forward but say a car is coming and I don't want to go yet my car moves about a foot forward and I feel the brake pump up and then resist my foot. The same thing happens if I put it in R she rolls back a foot and stops. I don't recall noticing it before the great ECU update but I also can't say it didn't happen before the update was accomplished.

Car is in for knocking sound made when you are stopped and you turn the wheel quick from left to right. Also does the same thing when you hit a bump. Dealer is saying it was always that way I say bs. 2008 prius.

I'm getting this warning light coming up frequently - it's the same light that appears when I engage the foot brake.
Does this mean something thing is about to catastrophically fail?

This was quite unusual for me, but while I was driving down afternoon highway traffic, my left resting-feet accidentally bumped onto the e-brake. My Prius made a single beeping sound, but I don't think I fully depressed the brake at all so it kept on rolling and the e-brake light never stayed on.
I wonder if that did any damage to my Prius at all with a slight depress of the e-brake or if it wasn't anything at all?
