is it ok if i change my rear brakes first because its going out before my front ones?if so which pads should i put cause stock pads leaves a lot of dust?will this mess up the bleeding system sequence if i just bleed the rears?

 

Seems weird that your rear pads are wearing out so fast, since a vast majority of the braking gets done by the front brakes. My rear pads last 2-3 times longer than my fronts. U carrying a bunch of bowling ***** around in your trunk or something? Ha Ha.

If you are going to take the time to bleed your brakes, dont be lazy - do it right and bleed them all, in the correct sequence.

As far as pad choices go... do a search - theres lots of good info.

 

the previous owner probably change the front before the rear. i have the car for a year now front still good

 

^that probably explains it !
