She doesn't look like much, but she's got it where it counts.

hi, looks sexy to me.
Did you mod the brake calliper to get the copper washer to seat?

Looking good!!

Any "special modifications" to the motor?

No, but now that you mention it, there is some slight "sweating" around that washer. Does the caliper need modification to support a banjo bolt setup??

Nope. Next step is a top-end rebuild and vapor blast.

Most of the Honda calipers are designed for the bubble of a brake line and they have a brass seat pressed into the caliper body with the proper seat angles for sealing. If you are using a banjo bolt I think the proper method for that is to screw a woodscrew or other screw into the brass seat and then pull the screw and seat out with your vice grips.


That would explain your slight weeping leak.

That looks amazing! I'll be happy if my 500 turns out 1\4 as good.

My question was slightly different. See attached photo. I’m planning the same. Best I can judge, if you use standard diameter copper washer, they’re too big to seat in the recess.

I wondered if you’d found a smaller washer or machined the lip off. If neither then I’d be cautious about the seal.

Words in there somewhere, haven’t figured the quote piece.

Hey, that's a great callout. I'll look into it. Thanks a lot!

Looks very nice and as far as I can see the wiring looks real clean. Also good to see the proper charger for the Shorai.

Regarding the caliper, definitely have to pull the fitting inside the caliper for the banjo bolt to screw in all the way. Here’s a link to my build thread where I show it.

For the copper washer, they are too large to fit inside the recess in the caliper so just slide it on a tapered wooden dowel so it’s tight, chuck it in a drill and spin it against a file that’s clamped in a vise to shave off the ID a hair. Use that smaller washer in the recess of the caliper and put another crush washer on top. Then install the banjo fitting, the top washer and your banjo bolt. So you have one washer on top and two underneath the banjo fitting.
