MG TD TF 1500 - Material for M/C liner

I'm going to rebuild my spare master cylinder and have it ready ... just in case.

I don't know the best material to use as a liner .. Stainless, mild steel, brass .. or what?

Gordon - Iwould go with mild steel or brass, stainless steel tends to take a rather rough finish that would probably shorten the life of the seals. Cheers - Dave

Gord.....the seamless brass tubing is readlly available in the correct ID, and is easy to machine the O.D. to size. Be carefull when you bond these into the cylinder with Loctite. Do not use the catalyst, because it activates very quickly with the copper in the brass and bonds before you get the sleeve all the way in.
I did cross hatch hone the ID of all my cylinders.
Boring the master cyl. is a little tricky even on a Bridgeport.

If you need enough for a few cyl's let me know I've got lots of it. These metal suppliers often have a minimum buy.

Sounds like brass is the way to go. I need only enough for a single M/C. It will cost me more in gas (Montréal - 70 kms one-way) to fetch a small piece, than it will if you can provide - plus, I'll know its the right stuff.

Advice about the Locktite much appreciated but specifically, which Locktite product is it?

I'll send you money for the piece and postage, to my US address in Chateaugay, NY 12920 (15 minutes from here)

Thanks for your kind offer. I'll contact you off the BB.

Stand by.

Hi Colin, when using Loktite how much clearance do you have between the brass sleeve and the master cylinder? My understanding is that a press fit will squeeze all the Loktite out of the joint.

I will offer a comment here. One of the problems a professional repair facility had a couple of years ago was leakage between the bored housing and the inserted sleeve. I don't know if it was because of over-boring, or porosity in the housing, or a "draw" in the brass sleeve when pressing it in, but it did generate a lot of discussion about machining the brass sleeve o.d. to size and then cold shrinking it before insertion.

FWIW

Dallas,

That's what our local XPAG Machine shop does - (cold shrinking) - seems to work.

Hugh.......I used Loctite 802 which is what one of the tech reps at Loctite gave me. I have had it in my brake cyl's for 10 years. It no only bonds, but seals. You do not want any seepage between the walls of the two parts. I had that and had to bore out the sleeve and start over.
You need to have about 1 to 1.5 thou. each side for a good bond joint. Coat both the cyl.ID and the sleeve OD and slip together.
