hi. i have search around the forum and cant find any info about it..

my car is just 2 yr 30000km only, and the mechanic told me i need to skim my brake disc...

is it normal for a 2 year car need a disc skimming? can any one share some info?

wat is skimming??

buang one layer of the disc brake ...
to make it rata again ...
ussualy for disc that already have surface x rata dah

er but for gen2 2 yr sudah x rata normal? or something wrong with my car??

thanks for the info.

Did you change your brake pads which leads to the mechanic asking you to do this? Trying to con you is it???
2 years old isn't old enough, 30k isn't far enough.

why the hell u want to skim ur brake pad in the 1st place? juz buy another new set lor then bed in properly
i think what he meant is skim the disc rotor.. but it is not nescessary as well as long as ur disc rotor is still flat
do u have braking difficulties like shaky when hard brake?
last time i skim 1 side rm30

yes i wan to change my brake pad. and he told me that my brake disc need to be skimed. i also feel 2 yr and 30000km sooo less ler.

is the disc surface suppose to be TOTALLY flat? i can feel very fine circular lines on the surface when i touch it with my finger.

i mean skim the disc, not the pads =)

normal brake no problem.. once i brake at high speed got feel a bit vibration, not till shaking lo

Yep.. if vibration exists then it probably requires skimming..

got vibration = not flat anymore
yes, it is supposed to be very FLAT or ur brake efficiency decrease lor.. for example:
u r travelling at 60km/h and hard brake.. ur car stop faster in flat road or bumpy road?

Was asking that just to know how you got that offer to skim it in the first place.

Anyways, fine circular lines, normal. If it's a deep scratch, not normal. If you brakes vibrate the skim, like what others suggested. The brake pads are running through some dips/bumps on the disk that causes that.

i see.. then wat would cost the disc not flat leh? cause 2 years only .. i rarely make hard brake..

Mostly due to wear and tear only... Your disc will be not flat but not noticeable... No point skimming it if you didn't find any problem with brake eg: vibration or noise...

Skim max twice. But some brake pads will eat up your discs, making them thinner and thinner.

I heard Bendix are one of them.

sudden temperature changes... causing it to expand and shrink at abnormal rate... molecul inside couldnt arrange themselves properly.... thus, u get warped disc...

alot caused lah.. most prominent cause is after a long journey drive and the disc rotor is hot, u rinse or wash the whole car and kena the disc rotor

i see.. then guess i gotta skim it..

wont got side effects right?

and btw will rs brake pads eat the disc up?

got after u skim the disc will be thinner.. u shd understand wat it skimming by now.. they ll remove the layer of disc to make the disc even again. thin disc ll break if under heavy braking.. so u must always keep noted of that. Skimming must not be done often. If u got extra $$ get new disc better..

u skim the brake disc..not the brake pad..btw..i skim last time 70 a pair...u need to skim if u can see lines on the disc..
b4 this my 'haus' brake pad makan the disc until can see small longkang on the disc

Clips for those who r interested
