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: Depends on the warranted life of the pads already on your car. If you have 10,000-mile brake pads, you need to replace them every 10,000 miles. However, if you hear a grinding noise coming from your wheels, regardless of the mileage on your pads, you probably need to replace the pads.
