Yeah I think if you have water in your brake fluid , And your brakes are dragging it heats the water up possibly too the point it makes steam this pressurises the brake system locking on your brakes as they cool down the steam will contract turning back into water and your brakes will ease off. This can then also allow pockets of air from the water boiling. Best bet too change out the nrake fluid and ease off the brake adjustment a bit .
