Brembo Spares & Service

[PEZBerq]

I need to replace some rubber boots and seals on both the master cylinder and caliper of my 87 Husky 510 twin pot Brembo disc brake. Does anyone know where to source parts for these elderly Brembo's?

Also how do you pull the guts out of the master cylinder without tearing off the rubber boot  . It is my first disc brake bike and I tore the dust boot off the master cylinder thinking it would pull off when it is captured by the assembly I got the internals out but I now have a torn dust boot that I can't see how to replace. There seems to be a steel ring pressed in that needs removing to install the new parts. Is this right and if so how do you get it out The teflon bush and rubber boot are captured by the steel ring and I mangled the teflon by levering it out through the ring    Any suggestions appreciated  .

11 mm I believe Walter. Is that a standard Brembo size?

Have been told that the retaining ring will come out if you make a tool that hooks in behind it and pull out.  A bit like an Ohlins shock tool doohickey - whatever that means  The ring clicks into a small groove and you have to be careful not to install it in with too much force or it will go past the groove and over crush the nylon bush and O ring I suppose. Drum brakes are so much easier
