Rear brake master cylinder rebuild kit?

[Ben990]

Can anyone point me to a rear brake master cylinder rebuild kit for a 2017 Alta Redshift MX? I know it is a Brembo, same as KTM, but I don't know which one to order.

I believe this is the brembo rear master (based on the P/N) = BR10850511

I was hoping to buy a rebuild kit, and I can't find one for this part number.

Its really weird that they dont have a rebuild kit for this P/N. Liquid does have new rear masters
7000053-01

And AOMX has this Moose Rear Master Cylinder Rebuild Kit KTM 12-20 or:

Rashid510,

I appreciate the replies.

Please clarify for me; the two rebuild kits you specified will work for the stock Brembo unit that came on my 2017 Alta Redshift MX?

Thanks!

The second link came off of a DIY on Youtube (

) for a Brembo rear master repair kit which is KTM specfic. The Alta Brembo parts are KTM derived so I will say possibly they can be used. PS13 (13mm is the piston bore) is the model.

The first link is meant for this rear master KTM: 77013060044 similar to the Alta rear master, but there are some features I cannot discern.
