Mazda - Mazda3 :: Intermittent Vibration Mostly On The Floor But Sometimes Also On Steering Wheel
I have a 2008 Mazda3 (2.3L automatic, 34K miles), which has recently been annoying me.. The problem started about 4 months ago, when I got new tires and a brake job (pads + rotor resurfacing). Ever since, it has been having intermittent vibrations. I feel the vibrations mostly on the floor, but sometimes also on the steering wheel. Here's what I've done so far:
When the vibrations started, i thought it was a problem with the new tires. I had them re-balanced 3 times at two different places, with no improvement. I then took the car to the dealer, who replaced two of the three engine mounts (it appears these tend to break easily on this model). This seemed to improve the situation for about half a day, and then it went back to the same. I took it back to the dealer, who could not find anything wrong. Not being satisfied, I took it to a different dealer, who could also not find anything wrong.
So, I am now stuck with this vibration.. It is not always there, and not always of the same magnitude... it seems to be more likely to happen in the morning after a colder night (well, as cold as it gets in Los Angeles). It is most likely to be felt at around 45-50mph, but you can also feel it at higher speed sometimes. A couple of times I could definitely feel it at around 25mph. Also, I've noticed that the engine vibrates when the car is stopped, at around 1500-1800rpm (e.g. when I first turn it on). The dealer claims that this is natural for a 4-cyl engine, but I had never felt a vibration before.
My gut feeling is that this is something related to the engine, but two different dealers could not find a problem... since this is intermittent, it is hard to nail down I guess.
Mazda - Mazda6 :: When Step On Brake Pedal It Resists For A Quick Moment Then Collapse And Go To The Floor
I have a 2010 Mazda 6 with an unusual issue. When I step on the brake pedal it resists for a quick moment then seems to "collapse" and go to the floor. The resulting braking is affected, but almost unnoticeable. When I quickly release the pedal and re-apply pressure the pedal doesn't quite "collapse" as bad, but still is not as resistant as it normally is. I have taken it to the dealership three times for this issue and they can find nothing wrong with the car, the brake pedal or brake systems. It doesn't happen all the time and is not weather or outside elements specific.
View 4 RepliesPassat (B5) :: Clutch Pedal Gave Out And Dropped To The Floor Without Resistance
Last night I was driving home and decided to show off at a light. I punched it pretty hard, but it wasn't anything outrageous.. anyway, as soon as I shifted to second, my clutch pedal gave out and dropped to the floor without resistance. I coasted it to a gas station, luckily.. When I lifted my foot the pedal rose back slowly. I tried pumping the pedal, didn't work. I looked for leaks, but none were found. I turned it off, put it in first and tried starting it, and it turned over and jumped/jerked forward, a lot like it did right when I shifted into second and it went out. So I'm assuming that its not the entire clutch cause it wouldn't have engaged the engine. It's not a leak. pumping it didn't work so it's can't be a pressure issue.. what is going on? is it my master cylinder, or maybe my slave?
View 7 RepliesGolf IV / Jetta IV :: 2003 - Clutch Pedal Went Straight To The Floor With No Resistance?
So last evening, I went to start my car and the clutch pedal went straight to the floor with no resistance. Car started and was extremely hard to get into every gear. Felt like the only thing pushing the clutch pedal back up was the spring underneath the pedal itself. Clutch pedal was 100% just the day before. Got the clutch line bled (vacuum bleeder) and it worked fine again.
Any clue as to what could caused this overnight?
Its a AWP 1.8t jetta with ASR.. I believe I came across something about a revision in the hydraulic line but I'm not sure.
Nissan - Sentra :: Engine Rev When Car Idles / Clutch Pedal All The Way To Floor Without Resistance
Since I have gotten my Sentra 2003 I have had issues with it. This past year my thermostat went about 6 weeks ago. I noticed that when my car would idle the engine would rev. Over the weekend I drove on the highway for 2 hours. When I started slowing the speed don I noticed that I could press the clutch pedal all the way to the floor without any resistance. It came back up. I rolled into the toll plaza and stopped to pay the toll at which point I could shift the shifter into a gear but the car would not catch. No movement. I think my clutch mechanism needs to be fully replaced as the car has 115000 miles with the original still intact. IS that most likely the case and what am I looking at for the cost?
View 2 RepliesSaturn - SL2 :: Clutch Pedal Goes To The Floor With No Resistance - Hydraulic System Failed
I have a 2001 Saturn SL2, with a manual transmission. The clutch pedal recently gave up -- it goes to the floor with no resistance, and I can't shift. I understand that this car has a hydraulic clutch, and that the hydraulic system has failed. My mechanic says the whole transmission system should be replaced, (though he hasn't been able to look at the car 'cause it's stuck in my driveway!) Before I donate the car to charity, could the problem be anything simpler? Or is it a straight forward diagnosis?
View 11 RepliesMazda - Mazda3 :: 2010 - Makes Noise When Stepped On Clutch Pedal
The noise sounds a little like a baby Road Runner, a soft little "meep" sound. I usually notice it after the car has warmed up, when I come and go from a stop sign. In lieu of strapping somebody to the hood with duct tape, I've been trying to think of a tunnel that I could drive through fairly slowly with the window down while I attempt to replicate the sound.
View 3 RepliesMazda - Brakes - Mazda3 :: Brake Failure Driving Slowly In A Parking Lot
Recently, the brakes on my wife's Mazda 3 (5 door, 2.3, 2005, 67k miles, automatic) failed while she was driving slowly in a parking lot. The pedal went all the way to the floor, but the car did not slow down. She used her key to turn off the engine (I've since suggested she use the parking brake instead). The car shuddered (presumably the engine slowing the car?) to a stop. She re-started her car and had some braking power, which returned to normal after a few pumps of the brakes. Since then, the car has been looked at by our usual mechanic and the dealer. Neither can find anything wrong and the brakes have been performing normally.
For it's age, the car is in good condition, has been regularly serviced, and has spent it's entire life in southern California. The only unscheduled maintenance I can recall has been the refurbishment of the electric window switches for the driver's door and some modest body work following a hit and run on the interstate (just dents and scratches). It's only other issues are an occasional rough idle when stopped at a light and harsh shifting from first to second or second to third gear when the car is cold (it's done this "forever," and I've always figured one of the accumulators was a bit sticky). The car was not serviced immediately before the incident. Is the car safe to drive?
Prius (Gen 2) :: No Resistance In The Pedal - Brake Turned To Back Out
I was waiting for my son to come out of his work for an hour with the car on. I got distracted reading and messing around on my phone, and since the heater and lights were off, I had no incentive to turn the car off since it was perfectly quiet (the gas motor only kicked on once to keep the battery charged). Then, I can't remember if I turned the car off or left it on while I took a nap for an hour (he was a total of two hours late getting out of work).
At any rate, when he finally came out, I don't remember if I needed to turn the car on, but I do remember that as I pushed the brake down, put it in reverse, and began to back out, I was moving kind of fast and pushing the brake down didn't slow my motion at all. Also, it felt like there was not much resistance in the pedal. I stood on the brake and there was a noise and a jolt as I came to a stop. I really thought I had stopped because I hit something, that's how violent the stop was. But my son walked around the car and found I had not. No dash warning lights came on. I pushed the park button, powered the car off and on, then put it in drive and coasted forward / carefully tested the brakes. All was good.
I put it in reverse and used the brakes without anything seeming out of the ordinary. Then we drove 16 miles home with no issues. Until this incident I have never had a single brake-related issue apart from grabby brakes when it is raining.
This is what I have learned:
When I stood on the brakes, that is the only time the hydraulic system was in play.
Rusty brake components are pretty grabby.
Actuators are expensive and no service center wants to replace them at 92K miles.

View 3 RepliesChevrolet - Tahoe :: Parking Brake / Pedal Moved Down With No Resistance When Stepped On
I was driving my 98 Tahoe yesterday making a visit to my sister. pulled the truck into the drive-way, put the gear selector in park, stepped on the parking brake (a habit I've had for years) and YIKES! the peddle moved down with no resistance!
my parking brake light stayed on even after I released the parking brake peddle, which didn't spring back, but I pulled it back. light stayed on when I started the truck although I think the brake never engaged in the first place.
I drove the truck and didn't notice any drag at all. after driving a few miles I stopped the truck and felt the wheels for excessive heat but didn't experience that. my guess is the cable broke or came off and didn't engage the parking brake in the first place. sound correct?
Golf/GTI VI :: ABS Allows Brake Pedal To Go To The Floor?
I was driving around today and had to hit the brakes really hard for the first time. ABS kicked in and during the ABS 'action' the brake pedal rapidly went to the floor. With each 'pump' the ABS made it felt like the pedal sunk slightly.
This was on dry pavement, a little gravelly / dirty and the car stopped rapidly, but just as I stopped the pedal was VERY close to the floor, and with just a touch more pressure it did in fact hit bottom.
Sounds to me like the ABS pump needs to be bled, is that right? Can I do that myself with a VAGCOM? I hate having the dealer do anything, even if it is their job. How to SAFELY confirm if cars does / does not do this as well?

My 04 Camry is having brake issues. It has 205k miles. The front pads are great and the back shoes are great. (Drums in back) I've had them adjusted multiple times but my pedal still goes almost to the floor. It's not the master cylinder cause I've already replaced that. The pedal doesn't bleed off either. But I have bled the brake lines and there is no air left in the lines.

My mother went out 2 days ago to go run errands, she stepped on the brake pedal and it went to the floor (car still in garage and in park, low mileage car 81,xxx garage kept). I have not been able to duplicate the issue. The fluid has been changed twice since new, no signs of fluid loss, undercarriage inspection revealed nothing. I am thinking maybe a vacuum hose issue.

View 19 RepliesF Series :: Brake Lights Only Come On When Pedal Way Down Almost To Floor
I drive a 1991 F-150 Lariat Extended Cab. Out of the blue, my brakes decided they didn't want to work unless the pedal is about 1/2 - 3/4 of the way down to the floor. As soon as I release past that 1/2 mark, they shut off. While this makes it great for tailgaters, it does not make it great for police officers.
We have already replaced the switch thinking maybe it was that, but alas it was not. I was reading in a couple difference places about the multiswitch? However, the symptoms other people had were similar, but not the same. I never tilt my steering wheel, so I dont know if that's the issue!
Prius C :: Pedal Went All The Way To The Floor On Sudden Brake
2013 Prius c Two, bought brand new with 15 miles on it 5 weeks ago. A few times when driving, I noticed the brakes seemed weak, like they weren't stopping the car very well even at low speeds (My driving is mostly in town on residential streets, so I'm rarely going over 35 MPH. Even so, I'd have to really mash the pedal all the way to the floor to get the car to come to a complete stop, otherwise it would keep moving forward. Several times I ended up about 5-10 feet past the line, sticking the front bumper into cross traffic. Luckily no one hit me. I chalked it up to the quirks of a different car than the one I was used to, and figured if it kept happening I'd take it to the dealership.
On Monday, my wife was stopped at a red light. The light turned green and the car in front of her started to move forward. After a few hundred feet, he suddenly slammed on his brakes. She said her brake pedal went all the way to the floor, and the Prius didn't slow down at all. She hit him going about 25-30 MPH and totaled the Prius. She's an excellent driver and I've been with her before when she's had to panic-stop. She's never driven a car without ABS, so she is used to pushing the pedal hard and keeping her foot on it. She wouldn't even know how to "pump" the pedal. She swears the pedal just went all the way to the floor and the car didn't slow down at all.
Volvo - Xc70 :: Brake Pedal Goes To The Floor
For the past several weeks, my daughter reports that she has to put her foot almost all the way to the floor to get the brakes to work. The brakes do not have an effect until her foot is 1-2 inches from the floor. It usually happens after she has been driving for a while without pressing the brakes. I’ve driven the car numerous times but haven’t been able to replicate the problem. Her commute is approximately 10 miles each way in stop and go traffic. The car is a Volvo xc70 with 200k+ miles. I've had it looked at by a mechanic who didn't find anything but it's continuing to happen. I'm suspicious that it may be a master cylinder problem and concerned about complete brake failure -- should I be?
