New Brake Shoes Locking Up 2004 Lehman Goldwing

[Ray & Paula]

Just wanted to touch base..... I contacted Wilwood asking them if they supplied Lehman with any of their disc brake parts back when they were being built.

Their answer was the following:

"From previous emails with other Lehman owners, I know the 11.2” rotor is 160-8484, and we still have some for $179 each.

There was also a larger 11.9” rotor, but we no longer have them. The rear caliper was a Dynapro Single, but I do not know which piston size they used."

Other than that, that's all they could offer regarding what Lehman used but, it's something. Of course, there are many other factors involved such as mounting to the axle, etc. The pictures in the Monarch ll manual shows a different rear axle than mine.

With only knowing about the few parts available and not knowing anything about mounting for disc brakes, I'm going to keep moving forward on my drum brake situation throughout the winter. I won't be able to road test but, I'll probably change out the PCV and will go over everything I can and re-bleed.

Once I'm able to road test or find something that may be obvious, I'll definitely report back here. If anyone has something else that comes to mind, please jump in. I Thank all of you here for taking the time in helping me out. I sincerely appreciate it more than words can say. Ray ThumbUp

Did You Ever Check The Rubber hoses ? I Thought I gave you a disc brake kit Number from Speedway Parts ? There was a story I read once about a Horse And Water, I don't remember the rest of it ?

Yes... You did a great job leading me to Speedway along with the part numbers. I sincerely appreciate that information and haven't discarded it. As you know, I've been kicking the disc brake decision around and even more so now. I was hoping I could find the same exact kit the Lehman used on the Monarch l including all the hardware and hydraulic lines along with Lehman instruction. Of course, that limb is non-existent. Lehmans Monarch ll installation manual helped some but, didn't get into the specific's when it came to parts.

Of course, not being a mechanic per say doesn't help. On the flip side, I've done quite a bit of mechanical things through the years therefore, I do feel confident about tackling the job. If I go that route, I want to make sure of everything that's needed plus great instruction that will work with my trike.

I did check a couple short hose at the SMC. I plan on going over more once I get the system drained again.

Right now at the the following point.....:gah: Thanks again, appreciate ya! Ray ThumbUp

Internal hose collapse is a very real thing and happens more than you think

I had a new Napa hose bad out of the box a few years back

Ray, Great information, thanks for sharing. I'm pinning this thread.

Ray, it will be a good thing once you get this brake problem behind you

Good luck and keep us informed

Hi Guy's! First, I want to Thank You for hanging in there with me!! I'll be back to hands on in a few weeks. I haven't been able to jump back in on the trike for one reason or another but, I have talked to a couple trike dealer's / installer's. Their thoughts on replacing the SMC is not to replace it since my hand test showed it working. I finally got my hands on an installation manual for the original Lehman Monarch like mine from SO Cal Trikes. It has the brake bleed procedure which is somewhat different than I received from our good friend Lee H. Mann (Jim) back in 2015 (link below). I've followed his procedure w/o any issues through the years therefore, I would think either procedure would work. The Lehman manual I just received shows the following procedure / sequence:

Front: Left Upper
Front: Right Lower
Rear: Right
Rear: Left
Anti-Dive: Left Lower Fork

Link to Jim's Procedure - Post 5
Rear: Left
Rear: Right
Front: Left Upper
Front: Right Lower
Anti-Dive: Left Lower Fork

Don't know if the Lehman Installation Manual procedure will make a difference, but I'll give it a shot.

I also came across another Honda SMC Service Bulletin Here dated December 2011. It shows on page 3 holding the SMC in a certain way for installation in which the others didn't show.

Moving on..... After looking at a Champion trike installation manual, I found that it had a pretty straight forward Honda GL1800 de-linking process. Champion did use disc brakes therefore, I'm sure the residual valve would be somewhat different since I have drum brakes. I contacted D&D Discount Motorcycles in AZ a while back to see if they could help me out with parts / process since they installed Champion Trike kits. In a nut shell, they wouldn't sell me any parts due to not owning a Champion. Champion Manual Here

My current plan; Since the SMC seems to be working from my previous test, I'm going to go over everything one more time > re-adjust the SMC per bulletin & re-measure piston > carefully re-adjust the brakes & re-bleed > Road test. If I hit another dead end, I'll re-check / check every brake line I can take apart and/or remove > Install the new SMC > Bleed > Road test. Although, I don't believe the SMC is the issue. Honestly if all fails, I would really just prefer de-linking the front / rear brakes.
I'll keep you guys posted once I complete my first road test as outlined..... I sincerely appreciate this forum and all of you that have jumped in giving me a hand for a resolution!! THANK YOU!! Ray

Sounds like a good plan Ray
