Iam trying to find a rebuild kit for a 1974 1.8L with a 17mm master cylinder, any ideas ? Thanks for the help.

I'm sure that you will be able to find one as ATE did have them available, but think about it!

These cylinders are old, and replacing it with a new one is not that expensive. I'd suggest that you would be better off by just replacing it and knowing you're safe!

I got a rebuilt 17mm master cylinder at my local NAPA. If that helps...

i would highly recomend splitting for the new one....
i belive the rebuild kit is not completely inclusive
and you may have to buy a new mc anyways if you find the rebuild doesn't work
never mind the posibility of what may happen if the rebuild fails to stop you while driving
my two cents

by the way
check out the teener tues thread...for the local nutcases

Hey! Who you callin.......... .......nevermind.


Oh yeah

I have some old brake pads if you'd like them too.

Yeah, but the whole idea of rebuilding a M/C is that when you're done it's not old any more.

I don't understand the fear of rebuilding a M/C. It's irrational. If you don't know how then don't, of course, but if you use good parts and you've got the skills then when you're finished you'll know exactly what's in there. You can't say that about any aftermarket M/C, and I guarantee that you'll care a lot more about how it went together than that Chinese guy who put the aftermarket one together.

Again, no skills - don't do it. You got the skills, what's the problem?

I've rebuilt them in the past. It is less work to just switch out the old for for a new one.

Do we go out and buy new brake calipers?

OTOH, a rebuild kit is nearly as expensive as a new M/C, so economically, it doesn't really make sense.

Brake calipers don't wear out.

Brake pads wear out.

M/C's wear out.

Ever take one a part? The are rubber "cups" or seals that move inside the m/c. They wear out by rubbing on the inside walls of the m/c. Much like piston rings in a cylinder. Unless you hone the m/c AND replace the seals your rebuild will not be as good as a new one.

Sure, the seals are the wear parts, are in the kit and get replaced anyway, so no problem. No need to bore, they usually clean up easily just with a hone. If there's corrosion damage that won't hone out then of course, go ahead and get a new one. You'd only bore and re-sleeve a M/C to salvage it when there's considerable corrosion damage and it's a collector car where there's no replacement available.

It's really easy to do, and you just use a small hone to ensure the bore is smooth.

Takes just minutes for a newbie to rebuild.

But then again we have been brainwashed to throw stuff away rather than fix it.
