Braking Problems

I have a 94 Tracker that when I drive at normal local streets or highway speeds it drives great. When I have to apply the brakes at normal speeds or at highway speeds the front end of the car shakes like crazy. Lately I started getting a noise that sounds like metal clanging together but it doesn't do it all the time. The shaking of the car does shake everytime I apply the brakes. I have changed both rotors, the brake pads and both calipers plus I bled the 2 front tires where I changed the calipers and it still does the shaking. This is a 2 rear wheel drive not a 4 wheel drive or front wheel drive. Any suggestions would be greatly appreciated. Other than my clutch cable snapping one time I have never had any problems with this car until now. Please help thanks.

Id check the runout on the wheel hubs where the rotor mounts onto the vehicle. Id also check the wheel bearings. I have a 96 Tracker and i recently changed the front left wheel bearings. In my case the bearings wasnt making any noises or causing a vibration, but it could be part of the problem.

Can you please explain exactly what to check for and how to remove the bearings. I have manualy check the suspension for anything loose and felt nothing odd. How do I check the bearings and what is the runout on the wheel hubs that you mentioned? Thanks for responding to this.
