hey all,

just took a test drive on the tsx. however, i noticed that before getting into the car, i saw some type of rustic build up on the surface of the disc brakes...but after the drive, the rust goes away but on the outer rim of the disc, the rust remains. i'm assuming that the calipers are responsible. is this normal for any car with disc brakes similar to the tsx? of course, the rust appears on a rainy day. thanks.

What do you mean by outer rim? Do you mean that if you look at the disc straight on, you wouldn't see the rust? Or is there a ring of rust around the outer edge of the disc surface where the pads grip it?

Yes, that is normal. If a car sits for a few days, rust will start building on the discs... especially if it rains. That happens all the time with my GSR. After you drive it, the pads will wear the rust off.

I've noticed rust on the outer rim as well, but it hasn't caused any problems.

Normal to have some surface rust where the brake pads don't touch.

yeah, it normal fer all cars!!!

unless u have a GT3 with ceramic rotors or something !!!
just drive around, ur brake pads will wipe off any on the braking surface, and brake cleaner will take off any thats on the top part.

that is completely normal. a fine layer of rust will develop on the rotors if left out in the elements for long periods of time.

the outer rim of rust will always be there because no part of the pad touches that part.

hope that answers the question.



didn't read many of the posts before me so ehh.
