53 --- Brake drag - drum brakes
Incorrect adjustment. Re-adjust the brake operating mechanism.
Drum warped or oval. This can result from overheating or impact. The condition is difficult to correct, although if slight ovality only occurs, skimming the surface of the brake drum can provide a cure. This is work for a specialist engineer. Renewal of the complete wheel is normally the only satisfactory solution.
Weak brake shoe return springs. This will prevent the brake shoes from pulling away from the drum surface once the brake is released. The springs should be renewed.
Brake camshaft, lever pivot or cable poorly lubricated. Failure to attend to regular lubrication of these areas will increase operating resistance which, when compounded, may cause tardy operation and poor release movement.
