Charlie4runner: Your problem in traffic is not the brake, but the driveline binding up at the slip yoke. I have had 3 4runners so far, the latest 05, and they all do it. Feels like rear ended by someone. The driveline has to be lubricated continuously and toyota is supposed to do this at every oil change ( they told me they do it even if not asked). Poor design of drive shafts and not likely to change. Once lubed properly, it may not occur for thousands of kms. Sometimes they dont do it properly, and once I was back there the next day to have it relubed again. This will solve your problem.
Never had any pulsing of the brakes, in fact, they are the best of any truck I have ever had. Got 80,000 km on 2003 4runner same pad and rotors and no vibrations.
The only big vibration problem I encountered was the Dunlop tires, pure junk. Usually out of round and you can feel this on highway speeds above 80 km or so. In fact on the ten tires with my two -2003 4 runners, I think 5 were out and could not be balanced. On my new 2005, I made sure it had the Michelins, and boy, what a difference! Vehicle is eerily silent up to 160 km/ hr so far.

The pulsing of the brake they are referring to is the brake booster buzzing. It's an annoying sound for it gets louder in the winter when it's cold and hums in the summer when it's hot. Toyota claims they made this system that way because the 4runner is a heavy truck. Also claim it's part of this new system the EBD (electronic brake distribution) The booster on the 05 model is made out aluminum as a pose to the metal one in 03-04 model. You can see this right away when you lift up the hood and look at the left on the braking resurvior.

#960 of 2607 Passenger Airbag Light
May 18, 2005 (10:58 am)
If you have a 2005 4Runner, please let me know if the words PASSENGER and AIRBAG are both illuminated in orange when you turn on your park and/or headlights. Right now, when I start my vehicle and turn on my park lights or headlights, only the word AIRBAG will illuminated in orange. However, I thought when I first purchased the car that the both words PASSENGER and AIRBAG illuminated in orange. The OFF and ON lights for the PASSENGER AIRBAG are working fine. Just need to know if the word PASSENGER should be illuminated in orange when lights are on.
Tried contacting several dealers and got varying answers. Please help!!
#961 of 2607 1995 - Rough Ride for 1st 1/10th mile
May 18, 2005 (12:00 pm)
Okay what do I try next?
If my 4Runner sits for about 24 hours or longer then I have this problem. If I am running errands I don't have this problem.
I start the engine. It starts fine. Even while not in gear I can tell when the engine is running rough. When I start driving it is a rough ride. But after about 1/10 mile it stops and runs just fine.
I've just had all the wires and plugs replaced. The mechanics tested the fuel injectors and they are all working in spec. The mechanic even replaced one that was close to being out of spec, but the problem is still occurring.
What are other things I should have the mechanic check? (I am clueless when it comes to vehicles - and I'm beginning to think my mechanic is too!)
#962 of 2607 decrease of rpms
May 18, 2005 (6:21 pm)
My '95 4x4 V-6 man. trans. 4Runner with 110,000 miles does this while braking:
RPMS go from 1000 to 250 when I start braking, then jump right back to 1000 again when fully stopped. During these few seconds the power brakes and air conditioner malfunction
and I've smashed a bumper or two because of this malfunction.
Mechanics tried everything (so they say) but no one has been able to pinpoint
the problem. I'm guessing it might be the knock sensor. Anyone has some ideas?
May 18, 2005 (7:20 pm)
you mean you clutch out and when the engine revs drop it almost stalls? It's some kind of sensor, probably, you are right. That is going to be a hard one to pinpoint, I am sorry. Turning the idle up a bit would be an easy but temporary fix.
juliennb: you mean it hesitates like crazy for a second then gets going strong? I would check the condition of the "snorkel" feeding air to the FI. If it is cracked (a common problem), then when you take off and the body flexes, it allows the intake to flood with air which causes the computer to go crazy trying to compensate, and you get all kinds of driveability problems. Once you are moving along in a steady state, the crack closes and it returns to running normally. Check that the large rubber piece feeding air to the FI has no leaks and is making a snug tight connection. Those things crack all the time.
#964 of 2607 Re: 2004 4WD 4R brake pedal making "hissing" sound (not worse sound/action)
May 19, 2005 (1:34 pm)
YES, my brake pedal makes the same sound and I asked a NON-dealer mechanic, who specializing in Toyotas and is great, to test-drive the car before I did the final paperwork, he drove it around the block and on the highway, said it was fine and great and about the "hissing" brake pedal said, Yeah, some cars make that sound and some don't, he said , "after a while you won't hear it." Most of the time I forget about it but it is annoying at these prices!!! I try to think of it as a sign of "tightness" and general excellence of the car (which I find is true!) but these posts can be unsettling!!!
