Prius (Gen 2) :: Unusual Noise When Put On Emergency Brake
May 31, 2010
My 2007 Prius has started making an unusual sound. At first I thought it was some kind of pump or something, but now???
When I put on the emergency brake, the brake pedal or when I put the car in park or take it out of park and put it in D, it makes a "chuck chuck chuck" sound, not high pitched, but not a low sound either. It seems to be coming from under the hood on the left side. It sounds something like a belt slipping or a pump with a squeak maybe?
It does not appear to make this noise when simply depressing the brake while driving, so I'm not sure it's the same abs actuator issue.

While the emergency brake was set, I happend to lean against the rear driver side of the the car and was surprised to hear a clanking, slapping noise coming from underneath the rear of the car; seemingly near the left rear wheel. What I think I'm hearing is the emergency brake cable (I assume this is a rear wheel cable brake) slapping against the vehicle frame or wheel axle. Even opening and closing the rear passenger door caused the cable to slap against the car.
This got me to experiment a bit, so I rocked the car back and forth and side to side. It's the side-to-side movement that causes the noise. The emergency brake works when set. The noise disappears when I release the emergency brake.

Our 1993 Saturn SL1 wouldn't start this morning (this never happens). After we turned the car off, it made this "dugga, dugga, dugga" noise that seems to come from below the emergency brake. Even though the car has been off, the noise has been happening intermittently since this morning. We just replaced the battery a month ago.

I'm experiencing an unusual grinding noise when accelerating from a dead stop but only in this specific situation.
1. When battery is at a low state of charge and the AC is on, therefore, whenever I slightly step on the gas the engine will immediately start.
2. Only under this condition, when I slightly press on the gas and the engine will start to charge the battery and propel the car at the same, there is a slight grinding noise coming from the front of the car. I don't know what this noise is, it sounds like gears grinding, it's very light though.
I know it's not the brake accumulator noise, because that's a whole different sound, and also this only happens under the condition I described above. When battery is low and ac is on, and the engine will need to start right away even when gas peddle is slightly depressed.
The best way to describe the sound is if you were to take a soda can and cut it in half and rub the two halves together (the edges) it sounds like that.
Also, there are no lights on the dash. It's a 2009 with about 73,400 miles.
The transaxle oil has already been changed maybe 10,000 miles ago.
The noise started recently, at least I only noticed it recently since it's summer and I have the ac on much more. There are no drivability issues, but the thing is, this noise was not there before, I know I'm not hearing things. You know when you drove a car for quite some time you will naturally know what sounds are normal and what sounds are new.

I have a 2007 Prius with about 77,000 km on it. Lately I've noticed that the car would make an unusual noise sometimes when driving at around 50 - 60 km/hr in stealth mode, with slight accelerator pressure such that the energy monitor shows power flowing from the battery to the motor (ie - not gliding or regen braking).

Emergency brake light, VSC, ABS, and (!) On, after 02 sensor replacement by local shop. I'm having trouble with my 2004 Prius. I have been having this issue shortly after having an 02 replacement. It has about 232,xxx miles and instantly I started having issues.

I just bought an '07 Prius with all the options except leather, and when I took my wife out to show her how it works, it didn't. The emergency brake light wouldn't go off and the shifter light on the dash would only go to neutral. We turned it off and on again (more than once) and finally the e. brake light went off and the zero showed up for speed and we could go. I'm wondering if there is some safety feature that won't let you engage to go until the e. brake is released. And if the light is on, the car thinks the e. brake is still engaged. Plausible? How do I fix it? Would this be the switch on the pedal?

From what I've been able to gather there is a proclivity in the 2004-2007 Prii for the emergency brake light switch to break resulting in the dash brake light staying on endlessly. Here is a diagram on page 4 (Powered by Google Docs) of the emergency brake system with the switch labelled and here is a picture of the switch itself (RockAuto Parts Catalog).
I've located my switch and found that one of the plastic side pins is broken off and the whole thing is swiveling around. The problem is that I can't figure out how to get it off so I can replace it with a new one. I don't want to go to the mechanic for something like this.
Also, some of the information I've seen says that I need to replace the entire emergency brake pedal assembly. That could run several hundred dollars and I'm not prepared to do that just so a silly light will go off.

When parking on an incline, say my driveway which is pretty steep, I engage my emergency brake. When I release the brake I get a creaking noise as I put it in reverse to back out of the driveway.Two questions is using the emergency brake really going to keep my car from rolling back down the driveway and does the creaking noise mean the emergency or rear brakes are being stressed by holding the car in an incline for several hours each day?
I really worry some days I am going to walk outside and my car will be in the neighbor's yard.

I own a 2005 Toyota prius and when I turn on the car, all the lights on the dashboard turn on but when the e-brake won't turn on when I put the e-brake on.

I just bought my 2001 with 153k on it and I notice that sometimes it didn't appear to fully engage in park. What I mean is that.... If I park on a a small incline occasionally after I put it in park and take my foot of the brake..... It will pop into park..... Or I'll have to wiggle a little when I notice the key can't be removed from the ignition. Now that I notice this.... I can make sure it is fully in park each time.
My emergency brake cable doesn't work (and I always do use this religiously on my other cars), and I think having it reduces strain on the transmission..... But darn its near 300 bucks to replace I'm told.

I bought a 2007 Prius 2 months ago and I noticed that when I stop at a stop light and engage the parking/emergency brake while keeping it in Drive gear the car creeps forward. I have more experience with manual cars where when you pull the emergency brake it locks the car and prevents it from rolling forward or back despite the car being still in gear, so I'm curious to know whether this is a normal thing with a Prius and pushing the P button in addition to the emergency brake at a stop light with a slight incline is necessary. I find that this two step process of disengaging the E break and putting the car back in Drive makes you slow to take off. But what I want to know if this normal with a Prius?

recently I replaced the front rotors and pads on my 02 Saturn SL2. I did this because there was a grinding sound coming from the front left wheel well and I had noticed a band around the rotor that looked gouged. All in all, about 30 minutes of work, following the Hanes manual. In the course of disassembling the front left caliper, I realized that the cause of the gouge in the rotor was from one of the tensioning clips on the caliper bracket. One of the flaps on the clip had bent back and was causing both the grinding sound and the gouge in the rotor. So naturally, I replaced all the tensioning clips as well. After putting everything back together, I took the car on a quick test drive around the block. The noise, while lessened, was still present. Furthermore, after I got to work this morning, I noticed that that there is the start of the same wear pattern on my brand new rotor.
What could be causing this problem to reassert itself?

Been driving my 2002 Prius since January 2005 and I've never heard this noise. It first happened Sunday as I was driving down the road, then this morning (twice) as I started the car. It lasts about 15 seconds for several "rings" of a shrill, electronic (definitely NOT mechanical) sound that reminds me of Emergency Broadcast System tests on the radio, or a really annoying cell phone ring. No visual warnings or lights are displayed (well, the Check Engine light is on, but it's always on, and my local Toyota dealership has been unable to shed any light).

Ok so this past weekend I finally got my car up and running with kinetics stage 3 kit took it out for a drive plenty of times this weekend everything turned out great. Car pulls really hard. I also installed some new coilovers and spacers. This morning I woke up and drove my car to my local general tire shop to get aligned. When driving It first sounded great but after about 10 min, And yes I punched it a few times, the car started to make a wahh wahh wahh wahh wahh wahh wahh wahh wahh. With the speed of the car. Not from the engine! Now I'm hoping it's a wheel bearing or something because I've never heard one before.

My 2010 Sonata GLS recently started to emitting some noise during acceleration, seemingly come from under the hood. The noise is most noticeable between 15-25 MPH, and is more noticeable when I go uphill. The noise also becomes more frequent with higher speed.
I have a shared m4a file with the noise recorded on Google Drive [URL] ......

Let my brother borrow my 98 S-10 and before he even got home with it he called and said the brake light was on. I figured it was the emergency pedal was down a little. Said there were no leaks. Got it back today and the fluid level is way down. Filled, but the low pedal is still there. Can find no leaks. Also the ck engine light is on. May not be related. Didn't get a chance to ck code.

Okay let me start by saying my car is APR Stage 1. The other day I was driving with my cruise control on and held in the accelerate button to speed up. After holding in the button for a couple seconds the check engine light and battery light flashed back and forth as if I changed some setting with the tune. Ever since that happened, if I turn the TCS off, the emergency brake light comes out and the error message 'check brake pads' is displayed on the MFI. Also, the weird part is that it's not just the light. The actual emergency brake is slightly on without pulling the handle. I can feel it when I accelerate. It's harder to get the car going. Once I turn the car off and leave it off for a few hours it goes back to normal. Why this is happening?

This morning I had an unusual problem after starting up the car. When the gas engine kicked in, the car started shaking a great deal as if the engine mounts had come loose and the engine was moving around. I quickly turned it off and waited a few minutes. When I tried it again, everything was normal.
Thinking back, I'm not sure if I put it in gear before the problem occurred. Wonder if putting it in gear just as the engine is starting up could trigger something like this.
