I had the brake and clutch fluid flushed today for the first time. The 7 year old fluid was very dark and was told it should be done every 2 years. Before going for the service I removed a fork brace and a spacer that had disabled the antidive. So now back to stock and can not feel any difference in the ride.
What about feeling a difference in the brakes? 7 years is waaaaaay too long to wait for a brake fluid flush.
You should feel a difference if the anti-dive was restored to it's original function; hard braking should keep the front end of the bike from compressing the front forks. Are the front forks still behaving in the same manner?
And why did you remove it?
The brakes did not feel bad or spongy prior to the flush, not a noticeable difference after. I do have progressive mono tube springs up front which makes a difference. I'll go ride some more and maybe get a bit more aggressive and report back if I feel anything different.Quote:

Did you ever get the brake recall done? The dealership replaces all brake fluid during the procedure.
I did have the recall done about 2 years ago. In fact I mentioned that to the svc.tech. when talking about the fluid condition. I thought the recall involved only the rear brake fluid.
As I remember I was asked if I would like to have the front break system flushed at an additional cost. I declined as I had flushed the front and rear break system’s the prior summer along with the clutch. Some reported that as a courtesy some dealers would flush the front break system at no additional charge.
My (I don't even want to say "my" - I've disowned those asshats) dealership really screwed up my bike during that brake recall; I've written about it here in the past. Screwed it up to the point where the entire rear caliper had to be replaced. This is why (and another reason of many) why I do all of my maintenance myself.
You be well advised to check all of your bleed valves and brake fluid levels after you've had the stealership touch your bike. Don't even trust them for one New York minute... :nono:
I was lucky to have a dealer nearby with loads of Goldwing experience. The owner personally does trike conversions, and his shop performed more of the brake recalls than any dealer in the USA. At the time (4 years ago) they'd done over 1,400 of the recall jobs. By that time they knew all the shortcuts, and had mine out the door in about 2 hours. I had no problems whatsoever.
B4 and after of clutch fluid I changed in July. Brake fluid was just as bad, last changed in 2016 when recall was done.

Wow!!!! That was some nasty stuff!!!
Yea it was bad.
Question....so how does it get so dirty in a sealed system. There is no carbon due to combustion or clutch fibers or wear material.
Basically...The world isn't perfect! All sealed systems are "open" a little because all matter has holes. The brake systems rubber lines and each connection point allows a tiny amount of air in and the air has a small amount of moisture in it. Over time enough moisture collects to break down the brake fluid and cause rust in the system. The break down process accelerates over time because more moisture in the fluid lowers the boiling point of the brake fluid, which causes more air/moisture in through the rubber lines, and so-on and so-on.Quote:

What is mind blowing is the countless cars and trucks on the road today that have NEVER had a brake fluid flush. Mainly they'll get a bleed when getting new brakes installed, but never a complete flush. There's a lot of very nasty looking brake fluid out there....
I've often wondered about that myself. I know my VW GTI calls for a brake fluid flush every 3 years. It's a 2013 and I've had it done twice.Quote:
