TRAC Valve Leak & Brake Fluid Mystery

[WingMan71]

OK, I have two separate mysteries, but I'm gonna put them in the same thread.

Front Brake:

I just did some routine maintenance on my '87 GL1200A this past weekend. Bled the brake and clutch fluid. First I'll rat myself out and say that somehow I skipped a year on this maintenance, so it's been two years since I did this service. (I have no excuse!)

All was good until I opened up the MC reservoir on the hand brake lever. The MC was almost empty! Yikes! I felt absolutely no evidence of a mushy brake lever or any other symptoms on the brake while riding. So, I was surprised to see that. I can also find no evidence of any brake fluid leak anywhere along that entire system, from the MC to the hoses down to the left front brake caliper. So, where the heck did that brake fluid go??? Two years I know, but still it's a sealed system.

Left Fork - TRAC anti-dive Valve:

Upon searching for a brake fluid leak, I found fluid on the speedometer sender unit (Aspencade with digital instruments) at the bottom of the left fork. At first I though, Oh that's brake fluid, but the TRAC valve only has fork fluid in it, so that's not it. It's got to be fork fluid.

Only other thing could be that the TRAC valve is leaking internally OR the bolt in the very bottom of the fork is leaking. I'm taking the front wheel off in the next day or two to replace the front tire, so I'll have a better look soon. If it is a leak in the TRAC valve, I'm concerned.

Can you even get repair parts and/or gaskets for the TRAC valves anymore?

Thanks for any insight or advice.
