Car Forum / Acura Cars / August 20082001 TL Rotors
When I bought my car used at 68,000km, the dealer had the front rotors machined due to shaking. At 85,000km they put in new rotors, again due to shaking. Now, at 107,600km, they replaced the rotors again because the shake was back. The dealer showed me the wear on the rotors, and told me they could not be machined. I'm no expert, but they seemed pretty worn to me. When I told the service manager I only had 22,000km on them, he said it's not only distance that count, but time too. Huh? That's 17,000km on the machined rotors, and now 22,600km on brand new rotors. 10,625 and 14,125 in miles, mostly city, each time over a two-year period. Is 14,000 miles on a set of rotors normal, or is there something wrong with the brakes on this car? Crappy Honda rotors? Crappy Honda brake pads? And no, I don't drive like a maniac. Signed, Puzzled.  Signature"What, me worry?" - Alfred E. Neuman How bad is traffic in your area? I had the front rotors on my 2001 TL machined at 59,000 kms to cure vibrations and they were replaced at 82,000 kms. At 104,000 kms, they might have to be machined again (very light vibrations when braking at 80 km/h or more), but they definitely don't need to be replaced. On mine, the vibrations issue never occurred during winter (different rims are mounted during winter). > When I bought my car used at 68,000km, the dealer had the front rotors > machined due to shaking.

Dealer said the rotors were OK and did not even need to be turned. No shake at all and the Pilot is heavier than than the Acura. I can only conclude that the Acura is "underbraked" as it were. Perhaps and aftermarket brake system would cure the problem. Wonder if the newer TLs have that problem. I drove my car from the dealer straight home yesterday, about 1 km, and this morning there is already surface rust on the brand new disks. Is that normal? >I drove my car from the dealer straight home yesterday, about 1 km, >and this morning there is already surface rust on the brand new disks. >Is that normal? Yes. The surface rust will appear whenever water gets on the rotors, and disappear after the brakes have been used again. Repeat ad nauseam.

Yep. One rainfall will cause rust on ANY rotors. Check out the cars in any parking lot after it rains and you'll see.

Two years, each time. >Where do you live? And how often/long do you drive? I live in Canada, so I get the slush and snow (and plenty of rain lately). I drive very little, a little over 10,000km a year, and it's mostly city, for short trips. I don't commute with the car, though, I take the bus and walk to work.

Time in this case is the operating factor, not mileage. Time and water cause major rust. Plus, you get patchy corrosion where the edges of the pads sit for the extended length of time the car sits. That patchy corrosion creates a frictional "boundary". As the brake pads cross that boundary in and out, the frictional coefficient changes. This is felt as vibration. That means the rotors are most likely not actually warped, just saddled with patchy deposits resulting from disuse. There is no way of removing such deposits outside of machining. Cars hate to sit. The more you drive them, the better they are. The more they sit, the worse they are. Unless you live in Phoenix, Arizona, where there is no rust...

They are cheaper, and according to what I have read on the 'Net, probably much better quality than the Honda rotors. Signature"What, me worry?" - Alfred E. Neuman |
