The first disc I wanted, was a Yam' Stainless, We have to look smart !!, But was later told they didn't work very well, This was in the 70s, With a set of TeleForks, The supplier messed me about for ages,Dear Bill,
I've also come across discs in the past that are not great in the rain. Early disc brakes on bikes were often cast iron that indeed did go a bit rusty. I remember early MotoGuzzi had iron discs. Perhaps a bit of rust gave the pads something to grab on. Later stainless or non-rusting materials were used some of which were just as bad when wet. Most discs used now are drilled which makes them lighter and helps dissipate any water. The right pads to match the disc material makes a big difference to working in the wet and having minimal
So I bought second hand Commando forks complete, And fitted Alloy race yokes.
I seem to remember Honda did a small plastic guard, To stop water getting on to the discs.
Cheers Bill.
