How often should i change my brake pads?

When ifirst get on it i'll do a ***** and the fugger will squeeeeeeeeak like a mug

 

a *****.......lmao!
my front brakes squeak like whoa, maybe i should change them?

 

just pullem apart and clean them with contact cleaner
say by by to the sqeeeksa lil emory cloth on the hub doesnt hurt either
and if they been that way for a while the shoes are probably glazed over, hit them with some emory cloth to just a lil scuff will be enough
the brake dust causes them to squeel
oh by the way dont breath in the dust
its not a good buzz like they say lol

ps
those are brake shoes
pads are for disc brakes
