Although you haven't specified what vehicle these breaks are attached to, breaks will get hot because, as they attempt to hold something to stop it from moving, friction will build up and both things will get hot.
i have a 93 nissan and the front brakes are getting hot when driving
This could be for a few reasons, but if they are getting hot without you applying them, I would suggest that they are sticking and causing the pads to rub on the discs, or if they are drum brakes, the shoes on the drums. If they are only getting hot as a result of using the brakes, I would suggest checking that the brakes are balanced properly, and that the front brakes are not doing all of the work/ or that the back brakes are working at all.
Front pads (disc brakes) Rear shoes (drum brakes)
Brakes do get HOT ~400 degrees actually. What is the symptoms your are experiencing, fading, brake smell, vibration?
front front - rear rear.
The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.
The brakes could be hanging up. caliper, or hose problem.
Front brakes have significantly more stopping power than rear brakes.
Yes.
Of course. All vehicles have front & rear brakes.
There are no emergency brakes on the front wheels of vehicles.
It is not necessary to break in brakes.
