When Hurricane Katrina struck the Gulf Coast on August 29, 2005, public health services in the region were devastated. CDC Director Dr. Julie Gerberding asked the CDC Foundation to activate its Emergency Response Fund to support CDC teams deployed to flooded communities and evacuee shelters on the Gulf Coast.nitial requests were focused on meeting the immediate needs of hurricane evacuees and health responders. Working with CDCâs Marcus Emergency Operations Center, the CDC Foundation provided grants to health departments to:
Clean the friction surface of the drum with solvent or brake cleaner so you don't leave oily fingerprints on the friction surfaces. Clean up all the hardware if you're not replacing it, and lube the adjuster with high-temp grease. Run the adjuster all the way in so the new shoes will clear the drum later. Now reassemble the shoes, adjuster, and springs and retainers. You'll need those photos or diagrams.
The only way to be sure of the condition of drum brakes is to regularly pull the drums and check the lining thickness. It should be more than 1/8 above the rivets on riveted linings, and 1/8 above the metal on bonded linings. If the linings are soaked with brake fluid, the shoes should be replaced at the same time the leak is repaired. It is usually recommended that brakes be inspected at least every 10,000 miles. However, rear drum brakes normally last about twice as long as front disc brakes. If you know when the rear brakes were last checked, you can get by with inspecting them every other time you inspect the front brakes.
