A "Clunk" After Pushing the Brake

I finally was able to capture the clunk i hear from hitting the brakes, what i found on the search is that it could have something to do with the pads and callipers.

It happens whenever ive been driving for a while and i approach a stop light, like a second or two after i depress the brake pedal. This is pretty random.

I have noticed i can make it happen on demand as i move back and forth between Reverse and Drive, Which is what i did in this video, it can be clearly heard at about 0:38-0:39. And at about 0:37 you can hear me push the brake pedal. Watch it in HD.

Sooo, does anyone mind clearing up what this could be and if anything needs to be repaired? As far as i can tell, the truck still drives perfectly fine.

 

My truck has always done this, from what I've found this is normal.

 

I hear the same thing when stopping at a red light and switching back an forth between reverse and drive. I saw some where in the forums that is has to do with the brake pads on our trucks. They have a lot of play in them that causes that clunk you hear.

 

Mine will do it slightly just after starting up and taking off in drive. The first slow stop I come to it makes that faint clunck noise, I can feel it in the pedal to... Then I really dont hear or feel anything after that.

 

Any of you know of something called axle wrap? I could be wrong cause i havent heard it mentioned for a while and it may just be on the first gen... That sounds like it could be it though

 

Naaah because i have a 4x2 PreRunner, so no front Diff or Axle .

 

Mine has been doing the same thing FOREVER. It even does it when I hit a bump/pothole. No clue what it is. Sounds like it's coming from the front left wheel area right?

 

its normal, just the brakes doing their thing. There is a thread somewhere about it, but no worries man its all good.

 

Axle wrap comes from the rear diff and leaf spring setup.

I had a loud clunk in the same circumstances as you. It turned out to be the the front suspension bolts were not tight. And also check your rear suspension bolts. Torque them all to spec, but be careful when tightening the front cam bolt in that you don't mess up your alignment.

EDIT: I didn't watch the video, but if its a loud metal on metal clunk, and not a "ting" sounds like others are saying, then it could be what was with mine

 

NORMAL! Your loud "Ting" in the video is pretty obvious. It's the same tone that the front brake pads make when shifting against the metal pins that slide through them. But rather than repeat myself from last month's post...

There a reason why there is so much play in them though? I remember reading a thread but never said why, just the way they are designed?

OP-Do not mean to seem to still your thread man just a quick question.

 

Yea I don't remember why they do it, someone in another thread explained it. But really no need to me alarmed by it.

 

Same problem here.. Another "Little oopsie from Toyota".

 

i thought it was just mine!! norms by the looks of things now

 

Yep, also read somewhere were Chris4x4 said it could be the truck shifting down to 1st when it comes to a complete stop

 

Same thing toyota says. When they actually try to give a reason.

 

If Toyota would have designed the pins, calipers, and brake pads to better tolerances, it wouldn't happen. But then you might have more difficulty sliding the pins through the calipers and pads. Still, there's too much space in between which allows them to shift. I've always worried that the pins would wear down when they're getting slammed back and forth over the years. But after almost 6 1/2 years, my front brakes have yet to fail. I'll be sure to let you know if they eventually brake and I crash as a result.

FYI, I believe the solution in the TSB to reduce the noise was to add grease to the pins (so you don't hear the "Ting").

 

Yeah lets hope we don't here that result from you. I have done gotten used to it

 

I've been hearing this for the past 6 months and thought I was crazy and looked everywhere for the source. The brakes seem to be the most plausible answer. A friend and I took turns trying to figure out where it came from and it sounded more from the tranny, but assuming both left/right brakes do it, it was probably tricking our ears to the middle of the front end.

 

Anyone confirm the problem goes away after replacing pads with say aftermarket green pads??? Brakes seem fine but, kinda embarrassing leaving work sometimes...
