If it's not the brake, it's time to take it apart and check the wheel bearings. After disassembly and cleaning, if the bearing, spindle, or hub have a blue tint to them, they have been overheated. The deeper the blue tint, the more heat the part has seen.Any wheel bearing showing signs of being overheated should be replaced. You've already got it apart and wheel bearings are cheap. In the case of an overheated spindle or hub, you should have them checked by a reliable shop who does front end and brake work as they may not be safe to use again.

If left too loose, the wheel is loose on the spindle. Too loose is better than too tight, but it affects the way your Mustang drives. This is where many problems in braking and handling comes from.

 

Loose front wheel bearings allow the brake drum or rotor to actually move on the spindle. To check this, you jack the car up and, with the tire off the ground, grab the top and the bottom of the tire and rock it from top to bottom. If it's loose, you'll feel the tire and wheel move.

 

If this is happening, your wheel alignment will change every time you turn the car, when you brake, and, most notable of all, while driving straight down the road. Every time the road has a change in it, such as a high center or grooves, the loose tire and wheel will follow the road, causing the car to pull from side to side. Not exactly what we want from our classic Mustangs!

 

 Another problem that a loose front wheel bearing will cause affects braking, if your car is equipped with disc brakes. Disc brake calipers squeeze the brake rotors to stop the car. When the brakes are not in use, the calipers are in what's called the relaxed state. This means that there's no pressure on the brake pads; they're just resting, a few thousands of an inch away from the rotor, waiting to be squeezed against it.

 

This is where a loose rotor can cause a brake problem. When the wheel bearings are loose, they allow the rotor to wobble. It can't run true like it's supposed to. Since the brake pads run so close to it, as the rotor wobbles, it pushes the brake pads away from the rotor which pushes the calipers piston(s) back into the caliper.
