Agreed, I have had many, but the XX is a different kind of beast! My rear caliper totally melted, still have it as a paperweight! Deffo flush it, and flush it well, then do it one more time. While I am sure you know, cleaning the return hole on the slave on the front fork is crucial - I used a wire brush bristle and hey presto! Will do a short video of what I used as reference as others asked, and hope it helps. Thanks for stopping by and good luck matey!

@@nikchristides4895 I really appreciate your video. A picture is worth a thousand words but your video on this particular issue is worth more. I am currently in a strange place and without a manual but your video alone is EXACTLY what I needed to see to help me through this procedure.

Video , made of two pages and me talking should be up soon. Good luck my friend!

@@nikchristides4895 question for you -i currently have the secondary master right here in my hand. How do you back the little filter out? Mine is stuck in the hole. I've tried pumping the actuator to create pressure to see if it would pop out. Nothing yet. Thanks

@@Guy-ky9mc from memory, I did the work on the bench, and used the tiniest flat head and toothpick to avoid damaging the soft plastic. Disconnect the whole thing and look for something flat to pry them apart. I think there is a small opening one of my watchmakers flat heads got in and I still gouged/deformed it a little 😬

I sincerely appreciate that! I will also try to video the two pages I used to clean the return valve on the front LHS fork slave (which activates the rear) , but .. drowning in bringing an RF900R to life

Hey Keith, our symptoms where the same. My caliper was so badly melted, it had the shape of the hub - like melted cheese - mine is now in the yard getting rusty as a conversation piece. I did not even try salvaging it! My recommendation would be to join one or two Facebook XX groups. There is a gentleman called Paul Manners, he is collecting parts, renewing and selling and think it's your best bet. The other idea would be ebay or something similar, to find someone dismantling Blackbirds. Join the FB group. There is some noise as always in FB, but nice group to be part of. Finally me personal theorem - the jobs we hate doing (like bleeding/fitting tyres etc) are the jobs we end up doing so many times we become experts 😆 Good luck, message again if stuck.

No. Having a poorly maintained (unflushed) combined brake system meant the debris did not allow the secondary located on the left front fork to release the pressure from the rear I would only recommend home mechanic to fix if you understand how the CBS works

I do not; but have a short video with a photo of what to expect when you take it apart. Recently did the job again - video was impossible due to the amount of brake fluid that goes everywhere 😩. Having done this so many times, disassemble the secondary master at the front fork (do drain the brake fluid first) liberally clean in a tub of brake fluid and consider a repair kit.

Drain fluid completely Crack the 3 torx screws Undo the nut holding the master in place (only one) Remove, gently remove rubber boot (mine tore hence needed new kit) Clean or rebuild.

One last thing. The two 10mm on the master hide the filter. Undo those, and even if you don't fully dismantle you'll see the dirt covering the return hole

Depends on what oil you mean. If bleeding, brake fluid yes. Engine oil should have no bearing with the brakes. If it does something went wrong somewhere!

Sfortunatamente no. Era troppo sporco e difficile. Unisciti ai gruppi su Facebook, hanno una foto. Proverò a postare un link.

Giorgio have a document to share, message me on Facebook if you want a copy

@@nikchristides4895 ciao, non uso Facebook

@@giorgiobassini8138 aspetta mi, will do a video of the instructions for you this week. I have been I'll, but should be ready next week!

Ciao Giorgio, I am uploading the two pages, apologies I couldn't do sooner!
