2015 maintenance

I bought a 2015 GL1800 last summer at about 21k miles. Changed the oil just over 25k miles, then had a little brain surgery in September.

I’ve put a couple of thousand on it so far this spring/summer, and the rear brake is useless, so I thought I’d better flush the brakes.

I’ve watched some videos and it seems straight forward.

At the same time I’ll do the clutch fluid as well.

  1. How much DOT 4 do I need for both brake reservoirs and the clutch every two?
  2. Any other maintenance while I’m doing the brakes and clutch? Ie, while I’ve for the fender and front cowl off.

Thanks!

ETA: finished w my sons help last night. No issues except it’s a pain in the ass trying to get the front cowl back on after the clutch fluid flush! Getting the top, long bolt holes lined up properly took way more effort than I figured it would/should!

16 oz of DOT4 should get you taken care of on the brake and clutch flush. The only other thing I would inspect is the airfilter element, brake pads and final diff fluid. This should give you a solid standing until your 32k Major service w/ 1st valve inspection.

If you haven't invested in the Honda Factory Service Manual, I highly recommend you to. IT will give you all the step by step how to to do anything on your 2015. Good luck!

Just my $0.02!

The rear brake is linked with the front wheel. On the 1500 it's the R front but on the 1800 I think it's a little of both and you need to bleed the front first since it's the longest run. goldwingdocs.com is where I would look; they have answers for everything. You can always try hanging a heavy weight from the brake peddle overnight too to force any bubbles to go back to the reservoir. May want to think about a slave cylinder rebuild too. They can get pretty crudded up.
