have the brake disc turned. or maybe, too much play in front end. Raise front wheel and try to move it side to side (with out moving the other front wheel) side to side slop means worn out steering linkage or control arm. Might cause vibrations. have the brake disc turned. or maybe, too much play in front end.

When there are any issues with your brakes it is best to take your car in to a certified mechanic. Brakes can knock for several reasons, including the calipers, brake pads, and bearings.
Have you replaced your rear pads or calipers? May have air in the lines. The reason the E- brake works is because it is engaged by a cable and has nothing to do with the hydraulics of your brake system.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
The Roller bearings can be used at all the places where the severe loading is applied at high velocity between two moving parts
Oil (in car). Grease (in bearings). Silicon. Water.
Hazard controls should be applied whenever there is an increased or unacceptable risk or hazard.
Brake calipers will sometimes not pull back from the rotors as they should and will make noise as the brake shoes literally rub the rotors continuously. This can happen even after changing both brakes and rotors. The contact points where the brake shoes slide back and forth on the caliper should be cleaned and have lubricant applied to prevent this. Also, could be a bad wheel bearing. There is a ball-bearing behind the hub that the wheel bolts onto which help the wheel turn with less friction. Sometimes those bearings will stick instead of turning. If detected early enough, it can sometimes be resolved by repacking them with grease(some cars have sealed bearings that cannot be repacked), but usually when they are as noisy as you imply they need to be replaced.
There are no calipers used with brake drums. Brake drums work with curved brake pads pressing against the inside circular surface of the drum when the brakes are applied. These pads are held in place and pushed by a spring and lever assembly that is mounted to a steel plate attached to the wheel or axle of the car. This plate does not move. Calipers are used with disc brakes to hold the brake pads on both sides of the disc brake and to apply them against the disc when the brakes are applied.
worn pads, calipers sticking or disks warped, more than likely pads though
Your brake rotors are warped and need replaced/resurfaced.
air still in lines. rebleed
There is a plug in the back of the caliper that has an Allen head screw under it. You have to turn the screw all the way in and then back it off 1/3 of a turn.
