brake calliper dust seals

[s.mac]

After the nightmare I had with my 2nd hand AP's I'm fully refurbing my old callipers that work on OEM M3 disks.

Ive cleaned them down and had them bead blasted ready for painting.
I will need to service all the parts which I can do but I'm having trouble finding somewhere I can get piston dust seals from, they are about

Front calliper seals - 50-52mm wide outer 36-40mm inner
Rear Calliper seals -43-45mm wide outer 30-33mm inner

they do just sit over the piston area to stop crap getting in.

Anyone know where they can be bought ? I have found sites in America but cant find any over here :whistle:

the rubber has got too hot and melted, I used to use backing plates and they were fine but then changed pad type and just used the stick on tabs for the pads, they obviously weren't up to the job .....
