As the banda are open on one aide, they cannot conform con-form to the shape of the druma unless they are of the right shape. If, when the pedal la pressed, the banda start to wrap from the bottom and continue upward on both aides, the chances of chatter are not so great.

If the banda are bent or kinked when the linings are attached, they will not grip the drums evenly, producing pro-ducing chatter and uneven wear. Squeaks are caused by the linings becoming bard and glazed, due to the friction and the application of pressure pres-sure which presses the grit Into the linings. Roughing the surface of the linings with a saw blade or coarse file will usually remedy the trouble, says Automotive Digest Probably an easier eas-ier way la to apply a mixture of castor oil and powdered resin to the linings.
