The mention of 55%, 80%, and 10% in relation to oil seals might reflect various metrics or considerations concerning their performance and application. For example, in many mechanical systems, seals can be categorized based on their efficiency, effectiveness in preventing leakage, and their material composition. A 55% rating might refer to a baseline performance measure for standard oil seals, whereas an 80% rating could indicate high-performance seals designed for rigorous applications. On the other hand, a 10% figure could relate to the failure rate or the operating conditions under which these seals can be compromised.

Another notable disadvantage is their performance in wet conditions. When exposed to water, drum brakes can diminish in effectiveness until they dry out, leading to concerns around safety. Furthermore, since they are often housed within a drum, maintenance can be more challenging, potentially leading to neglected issues.

Барабанні гальма мають декілька переваг. По-перше, вони зазвичай дешевші у виробництві та установці, ніж дискові гальма. По-друге, барабани добре працюють у вихідних умовах, оскільки вони більш стійкі до води і бруду. Це робить їх хорошим вибором для автомобілів, які їздять по нерівних або неасфальтованих дорогах.
