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 pads need replacement on disc brakes on a regular basis. How often they need to be replaced will vary depending on your driving habits. The accepted lifespan of the front disc brake pads is roughly 30,000 miles. This can vary greatly though. If you drive the vehicle hard and ride the brakes, the pads may need to be replaced in only 10,000 miles. The rear brake pads should last twice as long as the front disc pads. Again, this will vary depending on how you drive.
