A hot brake indicates the beginning of a stuck caliper. Brake fluid absorbs water. This will form a rusty deposit in the bottom of the caliper cylinder as the piston moves out as the pads wear. When you put new brake pads in and push the piston back into the cylinder, it will ride over this deposit and stick. It may not be noticeable at first, but they will begin to drag as the piston binds in the cylinder. An older caliper can seize as the deposits work under the piston and fuse it to the cylinder. It is very important to remove the piston from the cylinder when replacing brake pads to ensure the cylinder is clean. Brake fluid should be flushed yearly as should power steering fluid. If your fluid looks dirty, it is. It should be clear or amber colored.
