I've fitted my old Moto Guzzi V50 with Suzuki SV650 calipers with Carbone Lorraine pads.

I have to use the old Iron(?) discs but someone has told me these aren't compatible with the pads.

Which pad materials work with which discs and can you get them for my calipers??

p.s. if I break really hard the front judders ,it feels like the wheel is 50p coin shaped, I presume this is poor(completely absent) damping on the front forks.

Anybody got a pair of cartridges for KTM sx50 or Marzocchi pit bike forks???

The juddering sounds like headstock bearings to me.

I haven't heard of certain pads for certain discs, all I can think of is your mate thinks you have carbon ceramic pads or something, with them being called Carbone Lorraine? I might be wrong

Another vote for headstock bearings, can you feel it knock if you brake sharply from slow speeds?

Also Carbone Lorraine pads are freaking awesome, I used them on my car, but they ate through my discs and at £480 for a new set of disc's, I was not happy, awesome pads though!

No knock at all BUT they're ball races not taper bearings.

I'm used to failed taper races (and wheel bearings)as I also own a Honda CRM the worst bike ever for them.

If it is ..........B00locks............ the ball races are no longer available and a taper roller conversion is complicated.

It might not be, I'm no mechanic, but it just sounds like it could be.

It could be a number of other things as well, I wouldn't take my word for it!

On the plus side, you have an awesome set of pad's Very Happy

Hi

Had a similar thing with some cast iron disks on my FZ750. Plenty of pads seem to stick to cast iron disks (especially sintered pads) and these seemed to have left a "mark" of the disk that the pads seemed to judder over (same effect as warped disks).

All the best

Conversion? I replace the headstock bearings in my bike with taper roller bearings, and they were a direct swap. Bearings a bearings, so long as you get the right size, no?

Yup, I swapped all those loose BB's that were in the two separate races for a tapered bearing set.

I didn't have any problems.

I may be missing something though as I don't know this bike.

Even ignoring metric / imperial issues (not going to be a problem with a Guzzi), not on all bikes are the bearings races easily removed, or have ball bearings of a size where there is a common taper roller equivalent.

All the best

There's no straight swap. It's either get an adapter made or use too tall a bearing and miss a locknut out Shocked

The Disc/Pad incompatibility problem is apparently called "Graphite Glazing" but google gives me nothing .
