#143 of 167 2010 Sienna XLE rear brake failure
Feb 19, 2013 (2:22 am)
Sienna was at 42,054 at time of incident. At the conclusion of a 3 hour drive back home with the van, we had smoke rising from right-rear tire. The smell of hot brakes was very strong.
I got the van to my local mechanic and he confirmed that the rotor was toast, pads non existent and caliper had seized. He replaced the brake pads on the rear tires and put new rotors on both. We opted, due to cost, to replace only the right-rear caliper. He thought we'd be good.
Three weeks later my wife calls me that the hot brake smell was in the air again. This time it was prevalent from the left-rear tire. I was back at the shop once again with a seized caliper, but now on the left. This one was caught plenty early and everything checked out OK, but the caliper was replaced.
Is 42,000 miles too early for this type of work? The van has only lived in Southern Maryland and Virginia. It did haul a UHaul trailer almost nearly one year prior when we moved from Maryland to Virginia. It hasn't hauled anything since then.
I called a Toyota consumer line and they pulled up my information. They said there was nothing that could be done for us and it was just generalized as "wear and tear". I don't know about you, but I have owned many vehicles in my life and haven't seen such a wholesale failure of all the replaceable components like that. It was like they were on a timer.
We are also dealing with sliding door issues, which I understand there may be coverage for at a dealer.
Anything similar out there?

Loosing two rear calipers in quick succession tells me there is likely something systematic at play. If your mechanic still has the calipers, he can do a quick inspection to determine or rule out some possibilities.
1) Inspect the sliders, pins & boots for signs of corrosion or lack of proper lubricants. This would impede the release of the brakes. That would (possibly) indicate an original factory assembly issue.
2) Check the fit of the brake pads in the carrier for the same thing. If they fit too tight, they won't retract well. Ever have the rears serviced prior to this?
3) Does the piston move within the caliper easily? Pull the piston out of the caliper and check the inside for rust. That would indicate contaminated fluid. Given what happened, make sure your mechanic thoroughly flushed the entire system.
4) I once owned a Corolla that did this to the fronts. The new caliper seized up too within a week. It turned out to be bad rubber hoses that collapsed on retraction, trapping fluid pressure on the caliper.
5) Remote possibility, but it could be a master cylinder, ABS or proportioning system issue that is trapping pressure and causing the rears to drag.
No boat ramps or immersion of the rears in standing water?
I'm sure there are other possibilities, but that's what comes to mind!

Thank you for the reply.
The mechanic said last night that though it was unusual for calipers to fail this early, it wasn't as uncommon as I'd think. He wishes he had replaced both calipers three weeks ago and not just the one.
1) He made no note of any corrosion.
2) The brakes have never had to be serviced in our 42,000 miles. I was tracking pad wear for an upcoming replacement, having had our tires replaced last May. When I'd go in for the free rotations, we were monitoring brake pads. I knew pads would need replacing in the next 10k miles.
3) When the van was in the for the first failure (right side), the mechanic checked out the left side caliper and reported all pistons were working well. I neglected to say that during that first job, he flushed the brake fluid and filled with new, mostly due to the heat that generated during that 3 hour drive.
4) There was no discussion of hoses being checked. Unsure.
5) Mechanic spoke of this, but also said words similar to it being a very remote possibility.
In the end he feels now that we have replaced all parts in pairs, we should be good to go. He kicked himself for not insisting we change out the left caliper at the time. But he felt for us and the bigger bill we were paying with having to change out everything at that time.
No standing water or boat hauling. Just the one UHaul trailer for our move to Virginia from Maryland in January 2012. The mechanic had seen our trailer hook and questioned me on hauling as well.

I have my OEM pads and rotors at 58k miles, but no towing here. I do load it up with weight, though.

It sounds like you've found a competent mechanic who asked all the right question, so I don't know what more to add. Obviously if it were to happen again you go looking for the esoteric stuff like collapsed lines or a major problem in the expensive stuff under the hood (topic #5).
At this point you write it off to a random freak run of brake components bearing an original equipment defect with unusually precise timing. Maybe you should play the lottery this week? Hopefully, we'll never hear from you again - and I mean that in a good way!!

My 2006 Sienna had the same thing happen at 40,000 miles and I replaced the caliper and wheel had run very hot. At 80,000 the wheel bearing went bad due to the over heating caused earlier with the brake problem. We thought the caliper went bad because I drive a lot om gravet roads and it is dusty. Now at 100,000 no problem.

We are now at 42,000 miles and change. Since the left rear replacement of caliper, we have had no more issues in the last 2,000 miles. I find myself still checking after a long drive, feeling the rim... smelling for hot brakes. So far, nothing.
I hope it was just a freak coincidence. This van was supposed to be our 200,000 mile vehicle. I had never had seen such a brake failure in any vehicle I have ever owned. I started to doubt my 200,000 mile goal. We'll see what happens now.

It is August and the right rear tire "hot smell" has returned after a grocery trip this morning. February to August... 6 months and failure again?
Guess I'll be taking some time off of work tomorrow to see if the brake place can give me a caliper check.

For those of you following along, Toyota dealership identified a bad Master Brake Cylinder, rotors that needed to be resurfaced, and other brake fixes from my recent seizing issue. Total cost for the entire work was quoted at $1,800. I contacted Toyota Corporation for a little help. They agreed that at 47,500 miles I should have not had such a wholesale failure of my van's brake system.
They have taken to discussing my outcome and meanwhile the dealership is continuing to make the necessary repairs.

Good to hear that they are at least considering helping you. Good luck and let us know.
