Suggestion

Finally, if your discs just make the limit, but you're replacing the pads, replace the discs anyway because the new pads will quickly wear the discs below the minimum and reduce braking effectiveness considerably.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Is there an easy "test" to determine if I need to change my rotors? I am planning on changing my brake pads next weekend and I am just wondering if there is an easy way to determine if I need to change the rotors also...... I purchased my 2001 Boxster when it had 42,000 Miles on it, it has always been serviced by the Dealership, It now has 72,000 Miles on it and this will be the first time any work will be done on the vehicle not at a dealership.

POST 2Original post

As a rule of thumb, you need to replace the rotors every other pad change. Pads avg. maybe 35k mi. so at 70k mi. you're likely due. Or you can use a micrometer and check their actual thickness. Rotor wear limit for the Base model is: Front 22.0 mm Rear 18.0 mm For the 'S' model : Front 26.0 mm Rear 22.0mm If you don't own a micrometer, a cheap plastic vernier caliper (available at any Lowes, Menards or Home Depot for <$10) could be a substitute (though a less accurate one). Just be sure to take measurements at several places around the Disc and account for any 'lip' which may have developed from wear. Finally, if your discs just make the limit, but you're replacing the pads, replace the discs anyway because the new pads will quickly wear the discs below the minimum and reduce braking effectiveness considerably. Like it or not, discs are a consumable and part of the price of admission. PS Be sure to flush and replace the Brake Fluid if it's been 2 or more years, in a climate as humid as New Orleans, that's the maximum I would go w/o changing it (which also happens to be the maint. spec.).
