Show noise of squeaky brake may be remedied easily when a brako brake squeaks it shows that it la Is not doing its ita work efficiently as correct braking operations consist of a smooth gripping action without aque squeaks or chatter chatter Is caused by an alternative gripping and releasing of tie te bands on the drums this thia la in caused partly by the design of the bands and partly by tho the method of fastening the linings As the bands banda are open on one side aide they cannot conform to the shape of the drums druma unless they are of the right shape if when the pedal la Is pressed the bands start to wrap from the bottom and continue upward on both sides the chances of chatter are not so great greal but if the bands banda take hold first at tho the top the slack on both sides must inus t be taken up first before they will lie flat anthe on the drums producing chatter if the bands are bent or kinked kicked when the linings are attached they will not grip the drums evenly producing chatter and uneven wear squeaks are caused by the linings becoming hard and glazed due to tho the friction and the application of pressure which presses tho 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 way Is to apply a mixture of castor oil and powdered resin to the linings the former acts as a softener while tho latter increases the frictional resistance s si |
