Grabbing Brakes in Reverse

[LINKSTER]

Whenever I park (1 hr+) my 2010 class 1V on a small incline and then go to back up, the brakes violently grab the disks like they are seizing up. After driving a mile I can back up totally normal. It only happens on an incline and never on an even surface. Has anyone experienced this or have any idea what might be causing it?

This seems to be a known event. There's a thread that talks about this problem: braking in reverse

Here's how to avoid it from the link:

Someone in another thread had a solution that I tried and it worked: when this occurs push 'park' button, pump brakes hard a few times and then get back into reverse w/o jerky problem. Thanks who ever you were!

Put your foot firmly on the breake and then shift to reverse and you should be okay each time every time.

I haven't specifically noticed the problem but when I am parked on an incline I have my parking brake applied anyway. I put my foot on the brake pedal and turn on the car. Keeping my foot on the brake pedal, I release the parking brake and put the car in reverse. Then I ease off the brake pedal.

I'm not sure how you do it. That is why I spelled out what I do. Hope it helps.

Make sure you're not invoking the hill-hold feature and then
getting weird behavior when it releases.

This happened to me once while reversing out of my garage (level surface).

Had this happen to me, today. Level office parking garage.

The lightest touch in reverse caused the brakes to seize up quickly. Seemed to do it 2 or 3 times before it settled down. The gas engine seemed to have come on, too. It was almost as if the brakes settled down once the engine kicked in.

Grabbing Brakes in Reverse would be bad for your hands. Brakes Grabbing in Reverse is another issue.

it happened to me this morning, since i needed to move forward in order to not hit the car behind me, the brakes where pretty violent in the incline moving forward but not going on reverse. weird.

It has happened to me at least a dozen times on level surfaces forward and reverse. There is definitely a problem with this otherwise wonderful automobile.
I questioned the local Toyota service manager and they were unaware of any problem. I contacted Toyota technical services and they had not heard of any problem either.
They said they would make a note in regard to the VIN of the automobile. I honestly believe the NHSB should be involved in forcing Toyota to resolve this problem.

I've had the problem too, forward and reverse...but after pumping the brakes for a bit it goes away quickly....sure GRABS fast and furious until then...even the slightest pressure on the brake pedal and it really seizes up....noticed mine in forward motion first, not reverse...though I've had it happen both directions...and only when the car is first starting up.
