Clutch Leaking

Post by RockportDave » Sat Dec 22, 2018 10:22 pm



Noticed my clutch was letting out too soon today so went home and checked the master cylinder. Fluid was down to the bottom. Looked under the bike and fluid has been coming out the weep hole. Got slave and master rebuild kits coming. Bad thing is I will be home until December 30th and the parts probably won’t be here before then because of the holidays. Great riding weather here. Guess we’ll go fishing.
Just me and the Misses for Christmas this year. That’s odd with 5 kids and 9 grandkids, but they are stretched across the US and in Okinawa.
I did go through goldwingdocs Amazon tag to get the parts. I hope it worked.
Merry Christmas and Happy New Year to all!
Dave

Fishing is good. Catch a nice red for me. Good luck!

Hi Dave
I am having problems too. I have brake fluid leading out of the front by the top of the radiator. In my Clymer manual it says clutch hoses can crack and need to be replaced.
I called to order another clutch hose and they just came back saying Honda has discontinued stock.
Have you any tips for me as to how to determine if it is the hose or if is leaking out of the slave and master?

Have you checked the reservoirs for the clutch and brake to see if one is low?
I noticed my clutch was releasing very early and checked the reservoir and fluid was at the bottom. I checked under the bike and fluid was coming from the weep hole on the slave cylinder which means fluid was leaking by the piston seal. I don’t believe fluid was getting in the engine oil, but I am changing it as a precaution.
If you have fluid in front by the radiators, I would suspect the clutch or front brake hose is leaking. Brake fluid doesn’t evaporate or dry up quickly, so wherever the leak is it will be wet and possibly paint peeling if it got on painted parts.
Below is the routing of the clutch hose.

If you have clutch/brake fluid leaking, KEEP IT AWAY from any plastic (ABS) bodywork on the bike. Even momentary contact will alter the ABS and cause it to become brittle and easily broken. There is no fix for the ABS other than replacement.

Thanks WingAdmin
I have been covering as much as I could with plastic so that when I was bleeding from the clutch banjo bolt it would not leak on the bike.
Can you tell me which left side panels I need to remove so that I can inspect the clutch hose?
Thanks Sid Abma

Got the slave cylinder kit installed. Hardest part was getting the bleeder tube bracket bolt started. The tube bends easy and while removing the banjo bolt to put on new crush washers, I bent the tube slightly. Once I got it lined up and the bolt in, everything else went well.
The cylinder was pretty clean and I polished the piston with 800 grit emery cloth to remove the varnish. I also polished the lifter rod with emery as it had small pits where it sat in the oil seal. When I reinstalled the rod, I put the pitted end inside the engine so the oil seal had a clean area to seal to. The manual says to use silicone grease on the rod where it sits in the piston and I also put a thin film on the side of the piston that isn’t in brake fluid.
The piston seal was worn compared to the new one.
I brushed the paint off the engine where brake fluid had sat from the leak and sprayed it with clear lacquer until I can get some silver paint on it.
Soon as the rain lets up I’ll give it a road test.

Rode into town last night and the clutch is working great. It starts letting out about half travel of the lever and is very smooth.
I have a clutch master cylinder kit coming and will rebuild it when I get a chance.
The foot brake master cylinder was changed by the PO before I bought the bike so the hand brake master cylinder will be on the list to rebuild soon.
I’ll be looking for new SS braided clutch and brake lines in the near future.
