Do you think flushing will help...

Get rid of the 30+ year old accumulated crud in my brake system? I'd really need to ride this thing to work tomorrow...

This is what was dug out of my brake master cylinder today and that doesn't include what had gotten washed out in the cleaning tank or made its way onto my rag.

Need I say anything else?

I think that pic should answer your question.

How's the bore look Dale? Hope it isn't corroded.

Wow, it was still kinda working with all that crap in there?

[JEEPRUSTY]

Speaking of crap man I thought that is one odd question to post.
Not flushing is nasty.

I must say, that is the worst one that I have ever seen.
Usually, just mud. Not chunks! YUCK!!!

I think i would have flushed that one down instead of putting it on a rag and showing pics of it to the forum.

I blew my nose and it looked similar once. I had a terrible sinus infection.

Sorry gents, it was just my idea of sarcasm.

I don't really need to ride it to work tomorrow, in fact the bike in a zillion pieces. that's the master cylinder off my 78 GS1000E. I made this post up for those that THINK they can get away without completely tearing down the brake system on a thirty something year old, never been serviced it's whole life motorcycle.

Ed, I haven't had a chance to really inspect the bore yet. But, so far with a casual glance at it and the piston, it looks real promising for all the crap I dug out of it.

[Nessism]

I know.

I have read it before.

I need to redo my brakes.

I guess....

But springs is almost here.

Like almost now....

F*ck it! Ride the bike until the brakes fail, then fix um (if you are still alive).

[rustybronco]

Ed, I looked at the bore through my 5X eye loupe. The loupe's depth of field isn't as great as I'd like it so that I can examine the complete length of the bore (it's a 1-1/2" focus), but other than the hardened crud on the bores surface, the reservoir, cap and rubber parts being trash can material, it looks like it survived very well.

I'll throw it in the carb dip bucket tomorrow and know for sure.

Man, that looks like the dog got sick from eating too much chocolate.

If, by "flushing", you are referring to flushing the whole system into the trash, yeah, it'll be just fine.

Nah, just ride it.
Front wheels locking up unannounced at high speed is just part of the thrill of riding old unmaintained pieces of crap.

No worries my brother..I know a guy that has a good one in a box VERY close by. let me know before the other "starving biker survival kit" is mailed off. You do realise that bike is eventually gonna be at least 1/3 mine...dont you???
