Hi
I realize this is an old post, but I just started having the same problem with my 99 sienna... thumping/clicking sound from rear when I brake. Just wondering if you ever figured out what the problem was? Van brakes fine, just noisy.
 
Thanks
Patti

Hi Patti, I took my van to the dealer & was told that the noise was due to the rear brake drums & would need to upgrade to a new style which would run about $600. I then took it to a local car repair shop that a co-worker recommended & they resurfaced the rear breake drums and cleaned & adjusted the brake shoes all for $72 !! and the thumping noise has been gone since March 2008.
 
Good luck!!
Sue

I have 06 sienna bought new and the break is weak. I have one hit at the back and two near danger stop. Before I hit the car I drove at 40miles and have 30feet after him, I never expected the car cannot stop until I'm 4feet near by and I need add more force to the break, yet still hit the car at about 15miles and left two dents due to license nuts and my front logo dropped off. this happened less in a year ago with 60K miles in the car and after I have new front pads and fixed a caliper bolt stuck problem for about 30days driving.
  
After bleed break fluid (I will check rear soon) I retested the break. the full range is about 3.75inches thus too long to use it w/o moving my foot. At 1st one inch I can stop an sliding car at idle speed; 2nd one inch I can hear air push sound; at third one inch the air push sound is obvious; the last 0.75inch needs large force or raise my foot.
 
Compared with GS300, 1st one inch is nothing, but then nice sensitive and I usually needs 1.5inch for noticeable speed down at 40-50MPH.
 
I posted my problem in another forum and a few replies either says one has similar hit accident or this is a well known Toyota 'feature'.

I recently read a few posts about a malfunction that occurred after a recall repair of the Stop Lamp Switch Bracket so I decided to join this chat and post my experience to share with others.
 
I brought my 2011 Sienna in for its 1st service after purchase (3500 miles) and at the same time they did the recall replacement of the stop lamp switch bracket. Prior to this my car was running great - no issues at all. As I left the dealership, I noticed the brake pedal felt hard, like a rock with no give or squishiness – like stepping on a rock – and when I did press down on the brake pedal, it was very sensitive and stopped abruptly. This is an issue I never had before, prior to bringing it in for service. At the time, I didn't think it was an issue that maybe it was part of the recall work that had just been done, that they replaced the brake pedal. After about 1 mile, lots of warning lights (including the ABS light) went on and it was very hard to drive & control the car. At that point, I turned around and headed back to the dealership; it was very hard to drive & control the car safely – when I pressed the gas pedal, it was like driving with brakes on, there was lots of resistance & there was a burning rubber smell, when I took my foot off the gas pedal – my car would not glide, but came to an abrupt stop. It was hard to pick up speed & stopping the car became unpredictable. Brake pedal was still hard, with no give. So scary, with my baby in the car! I was so lucky that I didn't get in an accident - I was trying to navigate through a busy intersection during rush hour traffic and there was no place to pull off!!!!
 
The dealership still has my car after 4 days, they told me it might be a faulty recall part (the switch bracket). Toyota opened a case to investigate this matter and a Toyota engineer is checking out my car this week. Not sure if a new switch bracket will fix the issue - if not, next time I may not be so lucky. It seems this is a serious problem that's been happenning to lots of people - I wonder how many others there are that haven't spoken up? I decided to join this chat forum just to get the word out there to other people. I hope others do the same! It's only a matter of time until a real tragedy happens...after all, these are family cars.

Did no one bother to look at the brake lights to be sure they "followed" the brake pedal operation/application...??
 
Sounds as if the brake light switch is always closed and with the new brake override firmware fix that will disable the DBW throttle system.

I just went to the dealer to get some stuff out of my car and ran into a mechanic who said it was a mechanical error - by this he meant the mechanic made errors when putting on the new bracket assembly. I don't have much more info since Toyota is still doing an investigation and I don't have an offical report yet. I've seen a number of other cases similar to mine so it makes me think there needs to be better training to repair this recall - maybe it's a bit more complicated than expected. I'll know more next week when I speak with the managers and get a hold of that report. Until then, my car sits at the dealership.

For most cars with ABS, maybe all cars, when the brake pedal is initially depressed the system automatically checks to see that/if the ABS "reserve" brake fluid pressure level is as high as it should be. If it is not then the electric ABS pumpmotor is activated to bring the reserve brake pressure source back up to the functional level.
 
If, as I suspect, you were driving around with your brake lights always on ABS "armed"), then an ABS fault would undoubtedly eventually arise.

TY so much for sharing this with the rest of us. We are not currently having any issues, but thought we'd have the recall done on our next oil change. We will now be waiting to hear more ... and hopefully give Toyota mechanics more time to figure out what they are doing!
 
Please keep us all posted!! Thanks again!

Final Report of Malfunction: They had my car for 2 weeks & opened a case and a Toyota Specialist/engineer came in and the investigation revealed that the problem was improper installation – the brake lamp switch had moved position & was applying pressure to the brake pedal causing partial engagement of brakes (brake pedal switch was not adjusted properly)… Ended up they replaced rotors, brake pads, and front/back calipers. A 2 hour investigation uncovered traces of brake fluid at all four brake calipers – fluid had bypassed caliper piston seals indicating the calipers had overheated…I drove less than 2 miles in total with the malfunction in stop & go traffic. I requested new rotors & brake pads and all parts associated with malfunction – the caliper damage wasn’t something I thought of and am so glad an investigation was opened. The dealership took full responsibility and is working hard to earn my trust. It seems from all the research I’ve done, there needs to be more training or care when doing this recall. It seems like an easy install BUT THE MECHANIC NEEDED TO READ DIRECTIONS!!!!!!!!!!
