Bleeding the rear brake cylinder

Postby laforg » Thu Feb 18, 2016 2:03 pm



OK, I read all about starting with the front caliper, I get that. Connected system. But…SERIOUSLY? I gotta remove the left saddlebag to do the rear? What were the engineers thinking? Is there a safe spot I can use a circle cutter on inside that bag to reach the bleeder? Save me a couple of hours of work!

Possibly the same engineers who thought it was okay to have to move the left saddlebag to access the relays...

If you cut a big honkin hole in the left saddlebag to save roughly 1/2 hour labour to bleed the rear caliper, how are you going to check on the condition of the rear pads? ...SERIOUSLY?

Already did that layin' on the ground with a flashlight. Don't have to be a big honkin' hole…I've read that the newer ones had the hole built in, about 1 1/4 inch hole with a rubber plug in it

They do. You can see it here:

The "plug" is actually a rubberized plastic patch with adhesive on it. The adhesive wears off and you end up with it coming off, and then road spray comes into the bag. I used spray adhesive on the patch to re-stick it.

I've tried finding a "plug" that fits it, and have come close, but it was just a tiny bit too small.

WingAdmin, that is AWESOME, shows me exactly where to drill. Maybe I'll buy the plug first and cut the hole to fit! THANKS!!!

My 2000 has that hole, but between the size of the hole, and the size of my fingers, and the bending of the tubes and attaching a wrench...
It realy wasn't that hard to remove the left bag, just took a little time, and I was certain that I didn't leave any brake fluid on the rotor to contaminate the brake pads.

viewtopic.php?f=14&t=30304

WingAdmin put a nice pictogram post about " rebuiling the rear brake caliper" ..... in the how tos section go to that one and it tells how to remove the left bag.

I have since purchased a factory service manual. Really really good info in it.

Fabricating a little door doors may leak is it worth it?

Believe me, it is worth the time and effort to remove the seat, trunk under cover, left lower saddle bag corner and the left saddle bag. I for one do not want to have a mess of brake fluid all over the inside of my saddle bag and all over the caliper.

I have tried it doing it through the hole but Murphy's law intervened. If it can go wrong, it will. The hose popped off the bleed screw and it spit fluid all over the place and I had to take it all apart anyway to clean up the mess.

It is so much easier to just take it apart. While you have it off, install Speed Bleeders. That will be a big help too.

To put that plug back you could use the Handyman's, handy dandy secrete weapon.

You guys are real funny! Since I saw the comment about the hole being too small, I used the cutting wheel on the angle grinder to make one a little bigger. Worked beautifully, I really did need the extra maneuvering room because the MightyVac adapter wanted to slip off, I had to put a tie wrap around it, so I had to get my fingers in there. I'll install the doorbell tamarrah.

Wow, wonder if you got a bad one? I think they are made for the 1500 and that's what I've had, mine works great... It has a raised lip on both sides and the rim of the whole fits into the groove between the two...

Simply remove the old bleeder. Install a speed bleeder. Install a vacuum hose on the speed bleeder using needle nosed pliers. Takes all of 5 minutes. I've done two bikes recently thru the factory sized hole in saddlebag and I have pretty large hands. The secret is sticking your tongue out of the side of your mouth when threading in the speed bleeder. All kidding aside, it can be done without removing the bag, and thru the factory hole. Happy bleeding
