Xin, I know who's silver city is that. If i'm thinking of the same owner, he no longer has it. haha.
Btw, I'm running on Yokohama A Drive R1. no issues.
Vuilun, two possibilities.
1) surface rust/wet brakes. usually after wash car or in the mornings. sound or surface rust will go away after some light stopping at a junction or two. usually no issues.
2) your brake discs are warped. This happens when the brake pad material sticks to the brake discs especially after hard braking and not letting them cool down before you park your car. So it causes the brake disc surface to be uneven. The cause of this is actually Honda OEM brake pads. If you wanna solve this problem, change new aftermarket pads and discs at the same time. Usually you can bring your own pads to SC and they will help u install. Or, install new discs at SC, and bring your car to workshop to change pads.
FYI SC procedure is to skim twice before allowing u to claim warranty. If you close to your SA, ask him straight help u claim warranty and change brake pads also.
My car had the same problem. without fail it will occur cause the temperature rating on the OEM pads are crap. So i resolved the whole matter by swapping out the OEM discs and pads. Replaced them with Brembo Max discs, and project U bestop pads. Total damage around RM700. But from that day till now, no issues at all. But I have this habit when I park my car, especially after driving fast, to touch my rims before i walk away so i know how hot my brakes are. usually it's warm to touch as in i can hold my finger there for a while.
Bros.thanks ur comment and advise..it help me a lot...will try talk to my SC..
