When vehicle was turning left from a two lane state road onto a downhill country lane the vehicle brakes failed and the brake pedal was depressed to the floor. The vehicle responded to application of the hand brake. Subsequently, the vehicle brakes did seem to work somewhat when rapidly "pumping" the brakes to provide stopping ability. The vehicle was then slowly driven to the closest Toyota dealership (bill kidd's Toyota, cockeysville md). Part that may have become inoperable: Braking assist/master cylinder

Rear brakes locking up. I drove the truck a couple mile and we had a lot of rain and when I parked the car I set the emergency brake as always since it is a stick shift/ manual transmission. I went to go to the store the next day and the truck would not move since the rear left wheel was locked up. I called Toyota road side assistance and this was memorial day weekend and they wouldn't come to get the car because the dealer was closed and someone had to sign for the car. I was fortunately home at the time but did have to go to work on Tuesday and that would be when they came. I did some research on the internet and found out that I am not the only one with this issue. This is not called an emergency brake for no reason!!! what would happen if I had to use it in a driving emergency and needed to release the brake and it did not release"??" this car has 13400 miles on it and this is a serious issue if you ask me! I was lucky enough to figure out how to repair it myself with enough searching the internet and reading everyone else's complaints and freed the drum up to move the car so I can get to work but Toyota needs to step up to the plate again and correct the issue for everyone's vehicle including mine because I will not be doing this again while this car is still under warranty and has a long history of this. I wish I had known of this before I bought the vehicle!!!

12/9/17 there was a small amount of snow on my driveway. My driveway is slightly on an incline and then levels off at the top I put my vehicle into 4 wheel drive and proceeded up the driveway with no problem. I deactivated the 4 wheel drive and placed my vehicle in park w/O using the E brake. I never use the brake with this vehicle or my prior vehicle a Tundra. Two and a half hours later my daughter informs me that she heard a loud bang and observed my vehicle had rolled down the drive way striking a tree. When I went to investigate I observed that my vehicle gear shift was in park. Also there were tire tread marks on the grass and not skid marks. Question is why being parked for over two hours this occurred.

When decelerating at any given time vehicle loses compression at he brake pedals and feels as if though vehicle is thrusting and losing power to engine. And also when slowing down when speed reaches 20 mph, vehicle can be felt almost wanting stall.

I pulled up to park the truck. After put in park the 2017 Toyota Tacoma lunged forward. This caused the vehicle to hit a brick wall. There was almost $5950 in damage to the truck and the airbags did not go off. I watched myself crash into the wall and could not stop the truck.
