Too much braking and not enough changing the pads when they reached the minimum thickness?

In that case I'd be checking for trueness in the disk or it not running in the proper alignment to the caliper, but I'd have thought you might have noticed that because it must have been rubbing to wear the pads away like that in 800 klicks

It replaced a ScootRS disk and that thing rubbed all day long and i never had to change the pads.

All bolted up, the wheel spins without drag or rub. The caliper pistons arn`t siezed either.Fork links are true, uprated springs and new fork link bushings.

Wheel sits streight as a dye.

I`m really wondering if the edges on the saw disk were eating the pads, or realy soft pads.

we also cruised down to the rally on fast roads as a group, so we wern`t using the brakes as much as you would round town. The danish roads are pretty streight and flat.

I used to have a PM twin disk and that rubbed. Did about 6000km`s before changing pads and they still had pleanty of life in them.

Anyone else here running a pm disk with the new disk and caliper?

The saw blade discs are pretty aggressive on pads as I think they were designed for motocrossers to keep the pads clean and work instantly .The scoring looks to be the result of using fairly hard sintered pads and the newer PM discs wear the pads just as much.The Saw blade discs on a scooter are more a fashion fad over practicality.

It could also be that th disk hasn`t been de-burd after cutting?

Anyway, I`ve contacted PM and they seem a little shocked and asked which pads I had changed to (these came with the kit), so I`m hoping they will sort me out.

Silence from PM Tuning... Nice and sunny outside now after the shittiest summer in memory, so a bit frustrating.
