Brake Pads?
 

how long do they usally last? mine have done 4000miles but they feel a bit scrapy if u know what i mean they kinda hiss a lil bit but they arnt grabby, when i look at them when still on the bike in the caliper you can still see the groves and they look like they got quite a lot of meat left. should i take them apart just to check or will they be ok?

when i got the hissing sound on my last bike it ment the pads were worn right down but they still look fine at da mo maybe they could just need a clean?

cheers, have a gd easter

Take the pads out and give them a scrub. Also clean your discs. Clean out each and every hole in the disc and clean the surfaces using a brake and disc cleaner.

You should fine a marked improvement.

Oh and make sure that the pads go back in the same position. Left pads into the left calliper etc...

cheers ive only ever changed the front pad on my old nsr125 before (back one was to tight) i imagen it will be pretty much the same on my sv? just a case of taking it off then opening it up then opening the pistons wiv a screw driver or summin to get the pads back in?
