Hey everyone. New to the forum...however not new to Moto Guzzi. I recently purchased an 09 Vintage with 20,000 miles on it and the first thing I noticed when braking was the pulsing of the brakes, like riding a bucking horse. My 02 Cali Special Sport did not do this and my 02 EV does not do this with twice the mileage. It appears to be the front brakes. Happens with just the front brake applied and happens with just the foot brake applied. I don't know what to replace these rotors with... if they need replacing. I've cleaned out the bobbins with brake cleaner until they turn... not the solution. Are these semi-floating rotors, full floating? The bobbins on my EV do not turn but are fixed. If I have to replace them, what is my best option without spending tons of money. I want good reliable brakes. Most of my riding is sport touring. I don't need the absolutely best brake available.I need a good replacement rotor. A problem like this could not be caused by the brake pads, could it?
