The brake shoes should be renewed if the linings are contaminated with lubricants or hydraulic fluid
irrespective of the state of wear.
Check for signs of leakage from the wheel cylinders. Inspect the boots, also examine metal brake pipes
for wear, damage or corrosion and pull-off springs for damage or overstretching and replace as necessary.
Do not attempt to remove the adjusters from the backplate, if faulty a new backplate will be required.
Other than hydraulic parts, metal to metal contact points should be lightly coated with a high melting point
grease that is shoe tips, the areas where the shoe platform seats against backplate, the wheel cylinder
abutment slots.
DO NOT allow grease to contaminate the shoe linings, rubber parts and the friction surface of the brake
drum.
