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.
When you consider all the above factors, front brake pads typically last between 40,000 miles for stop and go city driving and approximately 60,000 miles for highway commuting driving. Rear brake components typically last around 80,000 miles for all conditions.
