Car Forum / Honda Cars / January 2005Rust on brakes in new Accord
Hi, I just bought a new 2005 Accord coupe EX V6 (manual transmission) and noticed that there's rust all over the rims of the brakes as well as a couple of other components in that area (but not on the brake surfaces themselves). Needless to say, I'm not very happy about this. Does anybody have any opinion on this? Is that normal or expected? Thanks, Mike > Hi, > [quoted text clipped - 5 lines] > Thanks, > Mike it's normal & expected. getting owners all wound up about it is a great way for dealers to make money though. in case you were wondering, brakes get hot and need to dissipate that heat. paint doesn't help heap transfer & tends to burn off. stainless steel doesn't conduct heat very well. so, being as disks generally wear faster than they rust anyway, they're regarded as an expendable item. high quality brembo disks are $30-$40 each. Jim (and the others who replied), Thank you very much. Makes a lot of sense when you put it this way. I'm definitely calmer now, and a bit smarter :) Mike >Hi, > [quoted text clipped - 3 lines] >themselves). Needless to say, I'm not very happy about this. Does >anybody have any opinion on this? Is that normal or expected? Yes it's normal. How could you protect the rim of a brake rotor from rust? It can't be painted or oiled because it gets damn hot. The rest of the brake assembly you can paint if you want to go to the trouble. Use a high temperature paint and take care not to get any where it's not wanted like the rotors, the pads or the exposed part of the pistons. Most people don't bother. >>Hi, >> [quoted text clipped - 6 lines] >Yes it's normal. How could you protect the rim of a brake rotor from >rust? It can't be painted or oiled because it gets damn hot. Not to mention your car won't stop until the oil/paint is worn. Not a good thing. ------------- Alex >>>I just bought a new 2005 Accord coupe EX V6 (manual transmission) and >>>noticed that there's rust all over the rims of the brakes as well as a [quoted text clipped - 7 lines] >Not to mention your car won't stop until the oil/paint is worn.

The rims of the rotors do get rusty pretty quick, and would probably dissipate heat better if they didn't, but nobody has figured out how to keep them rust free on a street machine.

Needless to say, I'm not very happy about this. Does > anybody have any opinion on this? Is that normal or expected? It's normal. You'll see quite a lot more after the winter's over. This past summer has been wetter and cooler than usual, and I'm seeing a lot more rust than usual on recently installed parts.  SignatureTeGGeR?

If you let the car sit in damp conditions for a couple days, then go drive it with the window open, you'll hear the brakes "grind" until the rust is ground off. As for the other surfaces, is that rust or is that brake pad dust? > > I just bought a new 2005 Accord coupe EX V6 (manual transmission) and > > noticed that there's rust all over the rims of the brakes as well as a [quoted text clipped - 9 lines] > > As for the other surfaces, is that rust or is that brake pad dust? Thanks for the reply. Regarding the other surfaces (and forgive my ignorance on their function): there are two components just above and behind the rear brakes. The one towards the front of the car looks like a black cap on top of a small metal plate, and the rim of that plate looks rusty. The other component looks like a couple of large bolts that are connected to the suspension, and they too have some rusty areas. Both seem to actually be rusty rather than dusted from the brake pad, but I'm less concerned now that I understand this is normal. Regards, Mike > Hi, > [quoted text clipped - 3 lines] > themselves). Needless to say, I'm not very happy about this. Does > anybody have any opinion on this? Is that normal or expected? Sounds quite normal. The iron parts of a disk brake are open to the elements and quickly develop surface rust. John >Hi, > [quoted text clipped - 5 lines] >Thanks, >Mike That's normal. The rust will be burned off after driving a few miles. Just leave your car outside for a few days of rain and you'll notice the discs rusting very quickly. I noticed this when I upgraded to alloy wheels where rust would start forming in the matter of 8 hours of work...I'd return to my car and the discs would be covered in rust. |
