BRAKES 25 INSPECTION Observe for wheel cylinder leak by lifting the rubber dust covers (2.1) on the cylinder. If leak is observed replacement of kit is recommended. If no leak is observed, check the pistons (2.2) for freedom of movement and temporarily fit an elastic band around the cylinder to retain the pistons in the bore. CLEANING Clean the back plate thoroughly. Use a wire brush to remove any corrosion, but take care not to damage the rubber dust covers on the wheel cylinder. Note: Never use petrol or kerosene, or paraffin etc. for cleaning brake parts as they are dangerous. Ensure shoe-sliding platforms on the back plate (1) are smooth and not corroded. If necessary, clean the filings and apply a light smear of Graphite grease (high melting point grease) to each platform. Examine the adjuster assembly to see it is in good working order and ensure the adjuster nut is free to run the full length of the thread. Care must be taken to fit left and right hand thread nuts properly.
