Thanks for the info LEDFT and yes I would be interested in hearing more details. I will get that measurement for you this afternoon.
Thanks!

LEDFT,
Attached are two (2) photos of the sleeve measurement that I took a few minutes ago. The distance from the top edge of the sleeve to the top of the metal plate beneath the circlip measured 1.930 inches. Hope this helps!
Thanks!
Bill
Absolutely , thanks . Ill try to get you the details today Thanks again
I haven't tested this yet , just fyi. I disassembled the original master ,to do that pop the reservoir off, pull out the rubber seal out from the secondary feed port , looking down into that hole there's what looks like a main jet , get a flat head screwdriver remove it , remove the end cap and everything should come out of the master . Next I cut about .25 inch off the piston end of the sleeve (not sure was necessary ) then without grinding the "sleeve" I carefully reduced the circumference until it slid into the new master .
LEDFT,
Thanks for the info! It will be a while before I do this work, but the information you provided will be extremely helpful. Thanks again and good luck with your testing of the unit.

Bill - Results- , working the sleeve until it matched the measurement you supplied, brakes work really good , better than I ever remember . Have only driven it 8-10 miles , but brakes feel good , so the custom fit sleeve works no doubt and wasn't hard to do.
LEDFT, thanks for the update! I am glad everything worked out. I will definitely be looking at doing this to my MC as well!
Thanks again,
Bill
LEDFT, well I am finally ready to install the new brake cylinder and brake booster. I had a few questions after looking it over carefully and I am hoping you can help me out. The new master cylinder is longer than the original and I had the following questions:
1. The new master brake cylinder has two ports along the cylinder with a bolt located between the two ports. Do you know what the bolt is for?
2. Did you use the new push rod supplied with the cylinder?
3. Did you use a new brake booster or the old booster? I purchased a new booster and it came with a new push rod as well, only slightly smaller than the one supplied with the master cylinder.
4. Did you have to modify the rubber seal slightly to allow the sleeve from the master cylinder to pass through the seal on the booster?
5. Did you have to rework the two brake lines to fit the new master cylinder since the new cylinder is longer than the original?
6. My new push rod OD that came with my cylinder was actually larger than the ID of the sleeve(0.432" push rod OD vs. 0.4145" sleeve ID). The new push rod OD that came with my new booster was 0.3745" OD. Did you reduce the diameter of the sleeve a lot? Do you remember the diameter of the push rod you used?
7. Just out of curiosity, do you know how to easily remove the master cylinder reservoir? I tried but it didn't move much.
8. Since the original reservoir has the fill cap on the front of the master cylinder and the new master cylinder has the fill port on the rear of the cylinder (windshield side) , did you reorient the reservoir so that the fill cap location matched the original cylinder?
I know have asked a number of questions, but any information provided would be greatly appreciated. I have also attached some photos of the new and old cylinders for your review as well.
Hi gvillbill,
1. the bolt between the two ports hold the secondary piston in place, only remove it to replace the pistons seals (see machining in the secondary piston).
2. the pushrod must be adjust with a clearance 0.035 to 0.045 in (see attachments)
7. you have to pull hard enough to remove the tank because it's clipped into the 2 seals, to put it back, I put rubber grease to facilitate reasembly
8. fill cap orientation doesn't matter
sorry for my bad english.
Thank you for the info and the photos. I appreciate it very much!
The larger reservoir feeds the front brakes. The orientation of the reservoir on your new master cylinder is correct. It looks like it was installed backwards on your old master cylinder.
Thanks to everyone who responded. I really appreciate the responses.
