Uneven disc wear and pulsing brakes.

EDIT : Do Moto Guzzis have these silly wafer thin rotors? They seem more sensible than most about such matters. What about Harley Davidson ?

Dunno about modern ones but mine uses std brembo equipment, non floating cast iron, weighs a ton (or tonne)

Cast iron is generally a superior material for rotors, the use of stainless is a cosmetic thing.

After some investigation, I've got myself a pair of new aftermarket discs plus new pads. I'm fitting them today. It was a mission getting the disc mounting bolts off, but that's done now.

In the manual it says to use "Thread Lock Super "1360"" (it was super alright... damn hard to undo).
Loctite 243 ought to do the trick though, right?

[imdying]

243 will be fine.

243 will be fine.

I've got it all back together, just in time for uni tomorrow.
I was going to just clean around the edges of the caliper pistons, but accidentally popped one out and discovered there was corrosion/gunk behind the seals, so ended up pulling them both apart and giving them a good clean. 4 pot calipers with twin discs have their drawbacks, it took ages. I'd hate to think what it's like with 6-pot calipers.
