I'm about ready to replace my front pads. But I'm wondering why nobody ever mentions having the rotor turned, like on a car? Not needed??
Also, I know there are variables, but as a rule of thumb, how long (miles) should pads last?
Happy New Year, BTW.

not needed, few post out there indicating it can't be done. even most cars don't need the rotors done today, but they like to tell u to get new rotors instead.
bike rotors need to be cleaned up with some sand paper, forget the grit # for the new pads.

Generally turning is not needed because there is only .5mm per side to play with. There is a guy that can "resurface" ones that still have enough "meat" on them, but I cant see how you can wear one to the point of needing work and still have enough to have some removed and have 4mm to be in specs. Just new pads is all that is generally needed until new rotors are needed which for most seems to be a few miles over 100,000......

If you run your pads to the metal, replace the rotors. There is not enough room to turn them usually. If you replace pads before they are worn out then you can get away with some light sandpaper,to resurface the rotors. Most of the time, they don't even need that  |

The rotors are so thin and if you tried to turn them, the lathe cutting bit will just chatter on the surface of the rotor. All you can do is grind them down, not a service that is very common. Buy new or acceptable used ones. Been there done that!  |

Mine are a bit fat on the outside edge lip and a little tricky to get the caliper/pads over, but still in spec. They don't get turned, they get replaced.

Turn rotors? Nope, replace when needed. (and the price has dropped) Front brake pad milage? I can't answer that. Everytime I've changed out my pads, they really didn't need it yet. Same with the valve adjustment, waste of time, never needed it. Timing belt, didn't need it. Spark plugs, didn't need it. However,last night I did change my engine oil, rear end oil and clutch and brake fluids and air up my tires. What kind of tires? What air pressure? What kind of oil? What viscosity? How long since my last oil change? I'll never tell This is my favorite riding season here in Florida...(winter)  |

I replaced the original pads at 20,000 miles.  |

Looks like they were ready.  What did the rear pads look like? |

I only have about 7,000 on the new front pads I put on when I got my 99 STD and they look to be at about 50% already. Anyone have a better option than oem? Sold my 02 shadow recently with 70,000 miles on her, and still had 25% left on it. whole different animal.  |

Brake pad wear is very rider specific, and also related to how urban your area is with traffic and lights. My OE pads last a long time.... but at tire changes, if they are anywhere close to gone, they get replaced.

Although that does seem to be a bit excessive I would point out that wearing the pads is much cheaper than wearing the rotors out. I'd simply get some more of the same pads and keep using them. I use organic pads and show very little wear on the rotors. *** |

just for conversation, a flywheel table grinder is the better tool for resurfacing a brake disc. Also ideally I think brake pads should be replaced before they reach the wear slots to dissipate heat better and not warp the the disc in the long run. Plus, the thinner the brake pad gets, the faster the rate of wear, as in, I've had to buy a new rotor because the thin pads wore out in an eyeblink and damaged the disc. Now I always keep spare brake pads handy.

I agree with the use of organic pads, your rotors friend. I have good luck using EBC pads on a couple of bikes. The price is right too.

It seems that about 90% of the users feel that you must use OEM rotors AND OEM pads to have good AND quite brakes. I tried EBC pads on OEM rotors--Not happy, toooo noisy. However, I have used EBC rotors (they cost less than OEM rotors) and OEM pads several times and they have always been as good AND as quite as OEM pads with OEM rotors. Just my personal experience.
