Toyota - Tacoma :: Brake Pedal Felt Mushy / Swoosh Of Air Coming From Rear Of Engine Near Firewall
May 28, 2012
05 Toyota Tacoma without traction control but has ABS. A few weeks ago I noticed the brake pedal felt mushy. I had my wife step on the brakes with the engine running. I could hear a swoosh of air coming from the rear of the engine near the firewall but more towards the passenger side. I did the following tests:
With engine off pump brake pedal and it built preassure and stayed firm.
With engine RUNNING held foot on brake and turned engine off. The brake pedal moved slowly to the floor.
Check the check valve in the brake booster and its good.
So, I replaced the Brake booster, bleed the air out of the master cylinder and bleed the brakes. Now it feels great for about the first 20min of driving but then goes soft again. and I'm still getting the swoosh of air escaping from somewhere in the same place as before.
I'm wondering if I have a vacuum leak somewhere before it goes into the brake booster? the connection is good where the vacuum hose comes from the engine to the brake booster. OR should I replaced the master cylinder?

Brake pedal goes to floor with no resistance first time I start in am. Rest of day all normal. Started when cold weather came. Fluid ok, no leaks seen.

My brake pedal is sticking down every time I push it in. I tried replacing the spring that was in there with a stronger one and sprayed the whole unit down with an all purpose silicon lubricant. It seemed to work a little but the problem is far from solved. It seems like it is sticking somewhere further away from the pedal. Master Cylinder maybe? I selected Tacoma because it's the closest option to my truck, but it's actually a 77 pickup/hilux.

2004 Toyota Tacoma... I drive 40 miles each way to work daily and sometime, usually 20 minutes into the drive, I get a vibration in the front end and felt through the floorboards and steering wheel, that get progressively worse until the entire cab is shaking. It lasts approximately 10 minutes and then it stops only to happen again on the next drive. Wheels have been checked.

I am looking to buy a 2012 Prius and I test drove it. Everything seems ok except each time I press the brake pedal there is a swoosh noise its as if air is being released from somewhere and I can easily hear it. Is this normal? the car is 95000 km on it. The dealer says it might be a normal hybrid noise. I currently have a 2007 Prius but that does not make this noise.

I recently purchased a 2014 Prius with the package 5 trim. I'm completely loving the car, but noticed when stepping on the brake pedal I hear a soft "swoosh" noise from under the dash. Almost like a short vacuum or sucking sound. The car has 500 miles, and I don't recall hearing that noise initially.

2001 F350 XL... Fitting on PS pump broke and I lost PS and PB with fluid everywhere. Replaced the hose with a new one from Autozone and I have no noticeable leaks.
I know I lost more than a quart but I could only add less than a quart (Mobil 1 Synthetic ATF). I'm also getting a whine from the steering wheel when I turn stop to stop. The power steering is back and there are no leaks (that I see) but the brake pedal is mushy. I've pumped and turned stop to stop for a while. Do I have to bleed the system like I'm doing a fluid flush? I hate to waste the synthetic fluid that I changed about two years ago.

My 09 Tacoma 91000 miles- symptom: when idling with foot on the brake, on occasion, experiences engine pause/subtle forward sensation; otherwise drives superb. Service shop said the issue is remedied by replacing the drive shaft thereby switching out the "yoke" which is the source of the problem. Shop said this is a common problem with 09 Tacomas. Does this need immediate repair or can I drive safely?

I got the attached warning today on my 2010 LS600. The pedal felt a little soft after the warning. It kept popping off and on, dinging every 30-40 seconds.
I checked the brake fluid, it was full. Car has 36k
I had it towed in to Lexus and they couldn't get the warning to come back up.

I have a 2005 F-250 4x4 and recently i noticed a grinding noise while driving and then when I come to a stop I hear a clunk and the grinding stops. It sounded like it came from the driver side wheel so I changed the wheel bearing assembly. About 3 days later it started again. Now it sounds like it's coming from both sides. I am at a loss. The hubs are unlocked. It's hard to describe the sound but to me it sounds like 2 gears with a large chain rotating on them. I hope that made sense. The clunk can be felt in the brake pedal.

The brake lights come on in the rear after i park the car. it appears the brake pedal is not springing back for enough to disengage the brake lights. It does not do this all the time, but seems to have start doing this at night when it gets colder. I can look outside and see my brake lights on, then go off, then come back on. It has made the battery go dead twice in the last week. is this a easy fix or something more complicated. this has nothing to do with parking brake, i normally do engage parking brake since i park on a flat surface road in front of my home.

My 1999 Toyota Tacoma (Ext Cab, 4x4 TRD) has 162K miles and now the clutch pedal intermittently sticks to the floor. I have to pull it off the floor with my toes while driving and have also felt the pedal start to pull back towards the floor on its own while the truck is in gear.
I'm looking for some wisdom as a few blogs/websites point towards a master cylinder, others say the master and slave, and my local auto shop said I need to replace the entire clutch assembly and throttle bearing. My truck is no spring chicken anymore but I'd like to keep it running for a few more years...

The clutch on my 2003 Toyota Tacoma has been acting funny for a while. I have to pull the pedal back up with the top of my foot about half the time, otherwise it acts like the clutch isn't all the way disengaged when I push the pedal to the floor. The master and slave cylinders have both been replaced as well as the clutch pedal mechanism itself (thought it might be the spring). I adjusted the push rod a little bit and it seems to have worked slightly but it's definitely still a problem.

I have a 2007 Tacoma 4 cylinder 5 speed. The clutch pedal started sticking about a month ago and has only happened a hand full of times. When the pedal is pushed to the floor it would stick, I thought it was hanging up on the floor mat at first but that was not the case. I went out to move the truck today and the pedal immediately stuck to the floor. Like usual I tapped the pedal kind of on the side to get it to release. the pedal then came back up. But now it wont push back in at all!!! There is only 1/2" of travel on the pedal and stops solid. It's like it is binding up on something. The spring seems to be in place the right way and nothing that I can see obviously wrong.

I have a 1997 toyota tacoma. The truck runs great. Last year I replaced the front calipers and breakpads. I drive the truck maybe 3,000 miles per year. The issue I have is that the brake light will not turn off. I checked the hand brake and it works fine. The switch on the handbrake is fine too. The really unusual thing is that randomly it will turn off. usually around 30-40MPH or when I have slammed on the brake. The brake fluid is fine. Is there a sensor in the rear on the rear pads that I may need to replace?

I have a 99 F150 4x4 (5.4) 173k miles. I bought the truck from family about 6 months ago and from time to time if you stepped on the brake pedal to hard (not locking up, but pretty hard) it would feel like the passenger rear tire would lock up. He said that there was an issue with the automatic adjuster on that side. Here lately the ABS light on the dash has been coming on every couple of days, of course on the next restart it's off. Could these two issues be related?

Passenger side brake light is not working. Bulb is fine. Seems that the "plunger action" in the socket may be lacking. I put some WD in there.....worked for a day or so....now not working. Can I replace this socket or do I need an entire lens assembly?

When I am coasting in reverse or forward at low speed e.g. 5 mph, I am hearing a whine that seems to be coming from the rear axle.
Usually it happens just after I have shifted OUT of gear (it's a manual transmission).
I uploaded the sound as a WAV file to here: Note! I recommend that you disable flash before going to this [URL]......
When I speed up the whine just rises in pitch and it's making my ears ring. What that sound might be? Maybe I just need some "axle grease" or something?

I've had a used 2007 V6 Camry for about six months now.
I recently started noticing a quiet set of rapid clicks/clacks sound coming from engine compartment/firewall area more or less on driver side. I'm not sure if it was there all along or if I just began noticing it.
It occurs after starting the car, putting it in drive and as soon as I let off the brakes and begin rolling. It might only happen going forward. I will have to notice if it does it in reverse.
It happens rapidly and stops and I don't hear it again until I repeat the steps above after the car has sat a while. I don't believe it will do it again, if say, after doing it once I stop, put it into park and then back into drive and go.
I don't believe it's the CV joints. It does it once and stops and is not related to movement of the steering wheel. It almost reminds me of a relay switching something.
I'll also add that I had a 1995 Prizm and 2000 Corolla that did the same thing. Both were manual transmissions. The click they made was much louder though their cabins were not sealed as well as the Camry. The clicks would happen only after the car had sat a while as soon as the car first started rolling and then would stop. Could it be the same thing in all three cars?

I have a 2002, Toyota Tacoma, extended cab, V6, 4WD. I purchased this new back in CA, before moving to CO. When the weather turns cold, a noise begins to start. The noise appears primarily when I am decelerating (just taking my foot off the gas). The noise sounds like chains rattling. I would equate the noise to the sound a diesel pickup makes (low rumble). The noise sounds (to me) like its coming from behind the passenger's seat in the floor. The noise is quite loud (people walking on the street can hear it and its apparent something is not right with the truck). The only constant thing is that it must be cold out. So, when spring comes, I tend to forget about the issue. We are having snow this weekend in Denver and its starting again. I have taken this to multiple mechanics over the years. They tighten everything up, but cannot seem to find or fix the problem.
