17` TRD Premium Rear "clank/clunk" noise

[fireforeffect]

I Googled this problem after reading your initial post again. The symptom your experiencing only happens with foot on brake after 15 minutes of driving when shifting into reverse. This is a rare symptom reported on other vehicle types with after market pads installed. Your vehicle is stock with 7000 miles. It should not have this problem. Has dealer inspected the brakes? Have you demonstrated the issue to the dealer?

[MENTION=211123]DougR[/MENTION], thank you for the intel. It actually happens every time, no matter how long I have been driving after switching from drive to reverse and then re engaging the break. Course of action:
1) Moving vehicle forward in drive
2) Stop vehicle completely
3) Keep break pedal engaged while shifting into R
4) Lighten pressure on break pedal to initiate reversing of vehicle
5) More forcefully reengage break pedal to control reverse --> CLUNK/CLANK

This did not occur when I purchased the vehicle. I just had my 1 year service completed yesterday- I'm assuming they inspected the breaks considering my complaint and did not find an issue. I will bring it back (which will be the third time) after your prior comment stating this is not normal.

Just returned from overseas. Issue is still occurring. The dealer is saying this is normal. Anyone have suggestions on how to elevate the issue to Toyota? Its annoying the S**T out of me, and if I attempt to sell the vehicle it is certain to raise red flags.

Again, the clank noise occurs after
1) Stop vehicle, foot on break
2) take foot off break (partially or fully)
3) re engage break (CLANK/CLUNK)

I'm going back to the dealer on Tuesday so any input would be greatly appreciated.

Suspect brake pads?

At first I thought it was a suspension issue (which really freaked me out), but upon numerous searches through various Toyota forums (T4R.org being the best - followed extremely closely by Tacoma World), I have ruled out my UCA's, LCA's & any other suspension movement because everything is torqued & tight.
I swear it's gotta be those floating disc brakes in the front adjusting to the vehicle now moving from park (or drive) to reverse - happens EVERY time (about 4 or 5 full tire rotations into the drive). This sound KILLS me!! It sounds like a loud'ish metal on metal clank & my beautiful rig is falling apart. I read on a forum that installing another disc brake clip on the top portion of the brake pads will help "tighten" up the brakes and keep the sound to a lesser clank....but I must have ordered the wrong clip size from John Elway Toyota (evidently John Elway owns Toyota dealerships?) & the ones that came are way too big to fit in the housing.
I highly doubt that clip would have done anything anyways, but in my desparation to get rid of that nasty sound I would try anything. Anyone else experience this? If so, is it normal?? I don't know how this could pass for normal...

*& yes, I have owned the vehicle for over 2 years now & just recently had the radio low enough to hear this upon reversing. I know...

Rant over...

That sounds like the same noise I'm experiencing. It just strange how its not a common problem with all 4Runners. My vehicle is bone stock and has 13,000 miles on it. I should figure out if the noise is coming from the rear or the front.

Also, what I don't get is if the brake pads shift and you can hear it when going in reverse, then why wouldn't you hear them shift back when you go forward?

That is the correct clip. The clips put a lot of tension on the pads, so just remove the pin, squeeze it into place and slide the pin back through. I just completed the same process for my front pads about a month ago. I installed 4 new oem springs (top and bottom) and lubed up the pin holes on the pads with an OEM caliper grease that I found recommended on a Tacoma forum for this issue. Brakes were completely silent for the first month. Just this week I noticed a faint clank coming back. The grease is really thick but I assume it's starting to break down a little and not deadening the clank as much anymore.

Dealership told me that same thing about floating pads. It's just so frustrating and really weird that it's completely random that one rig has the issue and others do not. Seriously makes you feel like you're driving a beater when there's a huge metal on metal clank every time you brake.

Are you planning on just dealing with it? I'm not sure what other actions to take unless elevating the issue to Toyota corporate. I bought my 4R new and it didn't make this noise.

For the time being, yes. The extra spring and caliper grease eliminated it initially and now just starting to barely hear it only because I'm listening closely for it. It's so quiet now, it's not an issue. It's been a month so I'm hoping it doesn't get any worse. If it keeps getting worse I will pull off the wheels and put on more grease. I attached the Tacoma TSB with the caliper grease part number. I found it on eBay for around $35.
