Any time I use my emergency break, no matter what the temperature is, my back passenger tire locks up. In the winter it is the worst as it won’t rotate at all until it decided to break loose, usually by hitting a curb. During the summer it will have strong resistance and will help if I put it in reverse a couple feet to release. I had the manufacture look at it and was told to just not use my emergency break. That some times water can get into the breaks and freeze them. But it happens at all temps including above 100 degrees.
