hi all.

i would like to know the position of brake pad relative to the brake disc..

1) is the pads suppose to touch the disc till the outer most area? or the contact area will fall within the surface of the disc and leave one thin uncontacted circular line at the perimeter or the disc?

2) can we adjust the pads position relative to the disc?

1. not too sure but both my brake pad are at outer disc
2. no, all the latch are fixed as what i can see

i had a funny prob.

i bought my second hand car almost 1 year ago. and recently changed the brake pads. And i find that the pad does not in contact fully with the disc.

now only i realise that the previous pads leave a thin protuding line at the outer most perimeter of the disc, while the new pads sit on top of the protuding line. This cause a untouched area of around 1 inch thick.

how is this possible? why my prevoius pad and current pad are not the same size? old one is smaller and new one is bigger.. or else it won leave a thin line at the disc as the position of the pads is not adjustable.

something is wrong.. all the pad must contact with the disc and not touching the outer most of the disc.. have ur car check before anything

i guess got a bit misunderstanding here.. haha. The untouched area i mean is on the disc loh. The pad ngam ngam sit on top of the protuding line, causing gap between it and the disc, leading to a 1inch uncontacted area, not the pad is outside the disc 1 inch.

with this i scare it might cause the pads to eat inside the disc at the lower area as more pressure will be transferred there.

Attached thumbnail(s)

That is still too big a gap. Looks like you got the wrong pads. Some setups do leave a very thin edge on the disc that is outside the edge of the pads. Mine leaves a very thin edge too but that is normal with most cars. That edge is usually about 2-3mm but not 1 inch like yours. Definitely wrong size pads.

er looking at the first pic, there is a polished line near the outer most perimeter, can see? and the second pic, the lower corner there the pad did polished the outer area also. initailly the disc is all rusted after i wash my car.

so the pad does touches the outer most of the disc, and wont be wrong size i guess. i think is the pad sits on top of the protuding edge, causing space between the pad and the disc, therefore the pad doesnt touch the rusted areas although it is on top of the rusted areas.

wat do u think le?

Your gen2 is it? If it is then it's definately not normal, mine is polished all the way to the edge

ya its gen2.

now it polished to the edge. but the problem is before this it was not polished to the edge, leaving a thicker line there. now it starts polish the line lo.

hurm....never encountered b4...what brakepads did u buy....???

KBS i think...

Draw a nice thick line using liquid paper or a paint marker or worse case a permanent marker on the disc (where u think it doesnt contact) to check for pad contact.

it can be seen from the rust right?

If you're really worried, have the discs skimmed and then replace the pads with the correct size. Not much options around this problem

yeah tot of that too. but now exam season no time.. maybe few more weeks later only will consider that..
