OEM Rear Brake Pipe replacement part about 10mm short

[mello dude]

I thought I would post this as kinda heads up thing.....

Since I discovered this as I work on the rear brake line replacement, I discovered the OEM part is short!
Kinda PIA, I can do a work around, but you dont expect a Honda replacement part to not match what is on the bike.....


Caliper end...


And fitting that mounts up to OEM hose....


Well, damn...  

[mello dude]

Oh, .... as a BTW.... Anybody know or find the torque assembly value for new brake pipes and hoses?  

I looked in the FSM, but I could be blind....

I would think that values similar to banjo fitting torque specs would work as a baseline...here’s a link to an example...

tech manual page 15-15   called brake hose oil bolt throughout manual
Install the brake hose with the oil bolt and new sealing
washers.
Push the eyelet joint against the stopper, then tighten the oil
bolt to the specified torque.
TORQUE: 34 N-m (3.5 kgfmm. 25 Ibf-ft)

That’s the correct specs for the oil bolts used at the banjo fittings that use a sealing washer on both sides of the oil bolt, but his question is about the pipe torque specs that don’t use sealing washers...it’s just where the flexible hoses meet the rigid pipes that run along the frame/swingarm.  Most would just tighten until it no longer leaks when the brake is applied, but he was looking for an actual torque spec.  Page 3-16 says to just tighten or replace if deterioration, cracks, damage, or leakage is present (paraphrasing).

I replaced the hoses last summer and just snugged the fittings so they didn’t leak while flushing the brake system.  All my banjo fitting oil bolts were torqued to the 25 lbf-ft specified in the manual.

I understand 25 ft-lbs for the banjos, but that seems high for the brake pipe assemblys.

Who has been using a 7/16 wrench on a 10mm fitting ?

How would you get a torque wrench on it to begin with ?

the 25 value is for banjo bolts only, not the pipe connection.

Snug to prevent leaks is the proper value....these can be over-tightened.  The picture you show looks like they were over tightened and with the wrong size wrench.

It wasnt me.... the Spiegler guy tried to take it apart...

I was thinking in relative terms... I somewhat know what say 17 ft-lbs feels like, as do 25ish or 12....

(makes me a little nervous about a brake guy)

They provide brake parts and go.... here you go..... but refuse to assemble it all...

I ran into a similar problem on an OEM Honda radiator hose for my Goldwing. The angle at a bend was wrong and would nearly pinch closed when forced around to the radiator. If I had to guess at yours, I'd say they measured the "finished" length and *then* bent it, rather than the "total" length. Seems the original supplier to the factory is no longer the supplier to the replacement parts stream. I called corporate Honda and complained, but their response was that I needed to take it to a certified Honda motorcycle dealer and let their mechanic figure out why the part didn't fit correctly.

did u read the page and foot notes?  something that is not listed is not critical so they give a torque per size of bolt/nut.

Did you read the instructions that just says to tighten so it doesn’t leak?

You can admit you were mistaken,,,it’s ok.  The stuff you’re referencing is for bolts, not hydraulic lines.

Adding new rear line install....
Overview shot.... New OEM front line and tube + Spiegler dongle for last line by caliper. They have the specs for the fitting and dimensions if you wanted to order.


Overview #2 - you can see the OEM line snake by the front of the swing arm.

[mello dude]

Since the OEM tube is short I had to trim the rear hold down clamp and also I cut a piece of thick wall rubber tubing to allow the clamp to grab on to. Worked out ok.
- The front OEM line mounts up fine in the stock mounts exactly. The clamp that hold the hose down by the swing arm bolts down together as it should... at top of the photo.

OEM tube lined up... zip tie is temporary.


Close up- I trimmed the hold down clamp + rubber tubing. The OEM clamp would not fit over the fitting hex if it wasn't trimmed.. since everything is shifted forward.
