Disc Skimming---is It Really Neccessary?

I overlooked the status of my car brake pads to the extent that the pads wereso thin that the metal part of the pad touched on the rotors and as a result the rotor surface became uneven. I have since replaced the pads with new ones, but now when I brake at high speed the steering wheels vibrate....this I believe because of the uneven brake rotor surface with only part of the pad touching the rotor surface due to the uneven rotor surface. Skimming the rotor would solve this vibrating and juddering problem...I have done it before.
My question is this..... I am thinking why should I skim and thin the rotor, shorthening its life span. maybe I should let the new brake pads keep on gripping....although got vibration...but sooner or later the pads will adjust to the uneven rotor surface to the extent that all parts of the brake pads will be in contact with all parts of the rotor, although both surfaces will not be smooth, but the vibration and shuddering should cease. Am I right?
Whats your advice sifus?????

It depends on how your pads will now wear the disc?
The disc is not only uneven worn but I suspect it is warp, that is why you are experiencing vibration on high speed braking.
If the disc is already too thin, I suggest your change the disc rather than skim as the disc has to be of a certain thickness to be used. Further prolong used will kill your pads, and then you will have to change the disc and pads again.
Don't play play with the brake system. They are the most important part of safety equipment in the car......

if u dont want to skim.. try sand paper-ing on ur disc, brasso it if u wanna cheaper solution get rid all the corrosion & dirty part.

Bro...I will go skim if really necessary......Bro vr2I think theres still room to skim. The rotors are slotted and the slots are still there, though if I go skim the slots probably gone and I end up just with a ventilated, non crosdrilled and non slotted disc.

bro. mosh,
He wants to get rid of the vibration......

oooo.. i tot vibration due to not so smooth disc...
errr .last time i got the same thing too.. but the mech said my break pump got clogged and it cannot disperse the brake oil? and at the other side, the thing that hold the brakepad was miss-allign..

Brake pump can get clogged ,meh ? Maybe brake hose possible ,only came across brake pump that leaks oil but clogged never before. What thing is that thing ,the clips or the caliper ?

For Slotted disc, if not mistaken if the slots disappear it is about time to change them already.
Anyway, if you are used to slotted brake disc be careful of not slotted disc as you may experience brake fade......

Brake pump is the one attached to the firewall and servo unit. They normally leak and not jam.
The other is the brake piston at the caliper. For this, we don't call clog but jam. If jam needs to be taken out, cleaned and fitted back using a brake kit.
For the brake system, it will never get clogged if you service and change the brake fluid once every 2 years. The other likely cause is damage to the brake line......
