How often are you supposed to get new brakes?
 

My f4i has 10,000 miles on it. Seems fine..still stops super strongs...just curious about how often to change pads..and when if ever you needs new rotors lines...etc

it depends how you stop. from fast speeds, or your weight as well.

best way is to check your pads.

You really only need to change them when they are too worn. Most brake pads have a wear indicator line in it, and a good rule of thumb (just to play it safe) is to replace them before the wear indicator disappears. You can prob take it a bit farther, but for the cost of new rotors, if you take it too far, it can be a pricey fix. You should be able to see the wear indicators while they are still on the bike with the aid of a flashlight

Here was my old rear pads after I pulled them off. Prob could have run them a bit lower, but better safe than sorry.

I'm sure there's some tutorials on here for changing brakes that might have better pictures than these

quick question---Where is the wear indicator??

It's that line in the middle of the pad. Hence, the flashlight to look down between the rotor and pad.

Pads can wear unevenly from side-to-side/end-to-end as well. So, be sure to completely check the pad all the way around.

Its unlikely at 10k that you need new rotors or lines...unless you are hard on your braking & have worn your pads down too far, or live in a rough climate. Rotors & lines can last an extremely long time or into higher mileage, as long as your good about changing your pads & fluid regularly.
