Is the rotor warped at all? If you don't have a repair stand flip your bike upside down and spin the front wheel to see if the rotor rubs on the pads. If so you might need to true the rotor.
If the caliper was not alligned properly to start with, the uneven wearing of the pads could cause this problem. Parts could have also shifted as things settle in.Leprechaun19 said:Strangely, the pulse was not felt on the first two rides - just after the 2nd ride.
The whole things is a bit odd - just want it to go away so I can ride without being jarred.
I have some fine woodworking measuring tools - will see if I can use one of those.
Thanks very much.
