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.
The answer to that question is in YOUR right foot. ( many less miles if you mistakenly use your left foot to brake instead of letting off the accelerator ) My 92 Explorer has only had one set of front pads and no rears in 140,000 miles. The 79 chevy p/u only has 70,000 miles and has never needed brakes.
