Need front master cylinder rebuild advice

I've got an '81 XJ750 Seca
I've ordered all my parts from Chacal, now I'm just waiting for the snail mail. I've ordered everything I need for the diabolically mounted front master cylinder rebuild project. I'll do the brakes later...another paday. So is there any advice you all can give before I begin this adventure? I'm SOOOOOOO used to starting something like this and it takes far longer than expected, or worst case I have to go to an "expert" to help finish. I've got the Haynes manual coming, so is there info that is irrelevant in there, is there additional steps that need mentioning that were left out?
I've ordered the circlip pliers
flex hone
reservoir screws and
MC rebuild kit.
the manual
and I have a mighty-vac pump for the brake bleeding phase

Any advice on bench bleeding the MC? Never done that before.

Does anyone have an MC filler screw cap they want to sell?

 

You sound like you have everything you need to complete the project to me. I just did on from a Honda, but I assume the Yamaha master cylinders are about pretty much the same. All there is behind the c-clip is a seal, piston and spring to contend with. Just watch what order things are in and put it back together the same way it comes apart, and you'll be in business. The main thing is to keep everything clean and use new fluid to bleed the system. Good luck!

 

When I bleed mine, I use a bottle with a 4-inch nozzle (rigged up some acrylic tubing) to top off the MC through the filler hole. Also, if you have a mighty-vac, you may not need to bench-bleed the MC... Just fill it, pull vacuum on the bleeder valve, and start pumping the brake. Make sure you keep the MC topped off.

When you re-assemble the MC, lube all the rubber parts with some fresh brake fluid. That will make everything go together a lot easier.
oh.. and don't forget to lube the cable that connects the brake lever and the MC.

good luck!
