Hi all. I just installed new Speigler brake lines on my '21. Everything went well on installation. Front brakes bled well. But when I went to bleed the rear, I got leaking from the rear caliper. Looks like it's not making a good seal on the caliper.

I've tried several of their aluminum washers that were included in the kit and it's still leaking. Has anyone had this issue? Can you recommend what to do next?

It's threading in easily enough, so no cross threading. Should I try different (copper) washers or is that a no-no?

Thanks!

I use only copper washers for any type of banjo connection.
Try that to see if the seal is complete with the copper. 🤞👍

Did they supply the banjo? Make sure it isn't too long and bottoming out before squeezing the washers.

I would try some copper ones myself.

I’ve got Speigler lines on both our 400’s with never an issue with either type of washer. Inspect both sides of the banjo and the mating surface on the caliper for dings.

Don’t get upset about this stupid question, but you are using a washer on both sides of the banjo?

Since I have a ABS bike and wanted to keep ABS my only choice was the Speigler lines at the time. Their lines are ok, but I am just not a huge fan compared to Core Moto.
The banjo bolts that come with the bike are aluminum colored, which I am not a huge fan of the aluminum banjo bolts because its a fine line of the right amount of torque before you ruin those and just enough to seat and crush the washers to keep it from leaking.

I always use a torque wrench on the banjo bolts to make sure they are tight enough to not leak. I want to say the aluminum I did 14-15 ft lbs on them and found that enough to seat the washer and make it seal nice to keep it from leaking. They say 12-14 so I would go 14 ft. lbs. The stainless ones should be 18ft lbs, but I usually do 18-20 ft lbs. I think 18 was my magic number to get them to seat just right.

I want to say at the front master cylinder I did the anodized colored banjo bolt and then at the calipers both front and back I did a stainless bolt that I had from Core moto. I have ordered so many of their lines, Core Moto and extra bajo bolts with washers I have extra. I use their stainless bolts with copper washers usually always.

You can find just copper washers at their site, or the bolts with washers.

Yes using washers on both sides. I'm using the OEM banjo and the bolt surface looks ok. I'll take a better look at the actual caliper surface tonight. Maybe there's a ding I didn't notice.

Thanks!

I did not use the OEM banjo bolts with the lines, or any lines for that matter. Also double check the torque, torque those OE bolts to 18 or 20 ft lbs and see if they seal better if still having an issue.

I looked at the caliper and it doesn't look knicked or anything. I'm going to pick up some new copper washers and try again tomorrow. Maybe call Spiegler as well.

Copper washers did the trick. Thanks guys!

Good job, and thanks for posting the solution!

Leaking like Markstrom eh? Thanks for posting solution, was gonna say just collect fluid in a cup - but they got all the cups in Edmonton...

I'm just glad it wasn't leaking like an expired, over-priced can of Campbell's soup. I'd definitely need a bunch of lottery ball luck to fix it. And even with that, I'd have a mediocre repair.
