Kawasaki Vulcan

I have a 2009 Kawasaki Vulcan 900 and I wanted to know if the disc brake on it is supposed to have grooves on it? My only front has different paths and I wanted to know if it was built that way.

It is normal wear and tear. When new, they are perfectly flat.

So when replacing brake pads, it should be noted that you do not 100% effective braking done before you, because the new pads dishes need time to bed in the groves.

Do not worry about it. There is a minimum thickness in mm written on the disk. If you have a high mileage example, you can measure it to be sure.

It is interesting to note that, sometimes, if the thickness is only .5 mm min suggested new ones. That said, I saw very little mileage rotors with cracks in the thinning on Japanese bikes. They are built very well for obvious reasons.

They get so use.

nope it does not have them! means there worn!

It depends on the size of the grooves ... sense only if its small grooves, wrinkles around the rotor which is just normal wear (assuming the bike is older). However, if there are two slots closest to the center of the rotor you probably wore the brake pad rivets right in the rotor. This means that its time for a new rotor.

No - sounds like its time to replace

I do not know about your bike, but both my old Kawasaki had sintered pads from the factory. They work hard in the rain and noise free, but they bear more records than the pad organic or non-metallic do.
