Show Leakage of Grease Onto Brake Drums Is Harmful Another condition that is the result of warm weather is the leakage of grease from rear axle interiors and the attendant excessive deposits of that material on the brake drums, especially es-pecially on the inner periphery against which the emergency or internal brake bands act. This reduces braking etli ciency to a considerable degree am': wherever such deposits are found, the; should be removed by cleaning the part's thoroughly wl!h gasoline, even if this should necessitate removing the wheels to gain access to the brake drum interior. The leakage is usually caused by the thinning out of the grease due to high operating tempera- I tares in the axle interior. Scientific American. J |
