AuditNetÂ® Audit-library::Internal-auditing-department-charters. The Internal Audit Charter establishes the departments position within the organization, authorizes the records that the auditor has access to, and defines the scope of internal auditing activities. It is important because it represents the contract between the internal auditing department and the organization.
When my front brake pads wore out at 23,000 miles, the dealer informed me that the rotors had to be replaced also, and showed me the wear on them. I had them replaced. Now, at 32,000 miles, my trusted local mechanic tells me the rear brake pads need replacing - AND the rotors! I have owned 5 cars before this one, and kept all into old age, but I have never needed to change rotors before.
Brake pads are not used in cars with drum brakes. It depends on the driver how long brake pads will last. A gentle driver can expect at least 25,000 miles on a set of front brakes. A vigorous driver may only get 15,000 miles. There are many types of brake pads; OEM, sport, heavy duty, and racing. The harder you drive, the faster the brake pads will wear out.
