Master cilinder resleave

I live in Michigan. I have had my 73 Commando for 47 years and need my front master cilinder resleave. I would like to get it done locally. I found a place in New York but expensive. Can anyone help me out with a contact.

Thank you Rick Taylor

I find the RGM sleeve kit to be the best one available, £49 plus VAT over here in the UK. Any half decent machine shop should be able to do the work for you. Are there any resellers of RGM stuff in the states? How expensive is the NY quote? I charge £40 to fit the kit.

Hi Rick, I made the move to the MadAss complete replacement item which was paid for and in my hands in under a week. It cannot be overstated how critical it is that this item on your Norton be faultless - this product is the answer to that. See here: https://www.tritonmotorcycleparts.com/297620488.html.

I used an RGM kit no disrespect to them at all but I was never 100% happy with it. I had it professionally done.
In the end I bought the Madass single disc complete set up and have never looked back.
I do understand it’s not for everyone so an option would be the Andover Norton replacement.
It’s identical to standard.

I brought a RGM resleeve kit but never fitted it, instead I went a complete Grimica front disc kit and the same as above never looked back, the stock front brake is so bad and one day it will let you down when needed as mind did without warning, now I have one finger brake if need too, my Norton brakes are as good as my modern Triumph, the stock brakes worked well new but they get worst as they age and I rebuilt mine a few times in the 46 years, have had the Grimica set up for over 12 years now and was one of the best upgrade I have done and at the time was just on $500 for a full upgrade, my life is more important than crappy front brakes.

The small bore AN replacement doesn't have an adjustable piston pusher like the RGM kit. This means that if your lever has too much travel (because the first part of the lever movement/piston travel just pumps fluid back to the reservoir) there is not a lot you can do about it short of getting a spacer made to take up the excess travel. The adjustable piston pusher in the RGM kit enables the excess travel to be dialled down to the minimum whilst still allowing the fluid to return to the reservoir. Doing this is where a lot of people fitting the RGM kit go wrong and either get the brake gradually locking on (mastercylinder not allowing the fluid to return) or excess lever travel (piston travelling a distance before covering the bleed hole)

Rick,
IMHO,you would be much better off getting a Madass replacement or one from AN with the 13mm bore.The sleeve kits I have used never gave me the confidence that I would recommend.Spend the money and get a new one.Just my 2 cents.

What make of sleeve kit have you used in the past? Rick asked where he could get his M/C sleeved locally and apart from my reply all the other posters have just voiced an opinion, and an expensive opinion at that. Not really what Rick was asking. The RGM kit is the best value for the money as far as i know. The sleeve isn't just pressed in (like other sleeve kits) It is a screwed bronze sleeve that requires the M/C to be machined and tapped to take the sleeve. Hence the need for machine shop facilities.
After dealing with a Mk3 fitted with the AN 13mm M/C that had excess lever travel (the owner wanted the front brake to be like the RGM equipped Mk3 that i own) is how i know that the the excess lever travel (of the AN 13mm M/C) can be tuned out with a spacer between the lever and the piston. I had to machine a variety of spacers with increasing thickness and by trial and error find the ideal one. End result a firm lever feel, better front brake and a happy owner.
I find it a little puzzling how some say they didn't have confidence in sleeved M/C's Did they not work? did it fail? If so, how?
Let everyone know how/why it failed would be more helpful than an opinion.

I have to agree with dobba99. Most of the answers were off topic, involving tossing the original parts and buying expensive solutions.

If the problem Rick is trying to solve is a corroded bore and he is happy with a sleeve with a stock bore size, it is a relatively simple fix and could be done anywhere.

Some folks have had issues when the the master cylinder was sleeved with a reduced bore, usually with a purchased kit.
I have sleeved two master cylinders, reducing the bore using the info contained here:

Worked great.

My apologies for getting off track of the original post. I am glad there are better kits out there now than what I used probably 8-9 years ago. I certainly wasn’t trying to offend anyone or spend their money.
