Twinpot Brake upgrade on 78 Skunk

Finished her up last night! Glad I looked back through this thread because I had missed the part of having to trim the speedo dust shied, but caught that BEFORE everything was assembled, so took care of that.

Everything bolted together perfectly, and DANG, these feel very nice. Proportional, smooth, and zero caliper movement when applied. I want to replace the front Progressive springs with some non-progressive rate springs, which I think will help with the dive, but otherwise, this is a nice improvement.

Thank you, Dan, for the elegant solution with those brackets and all the info on calipers and rotors.

Looking forward to this summer!

Howdy, neighbor. I looked everywhere for stainless socket head bolts in fine thread, no joy. Ended up ordering OEM for a couple bucks each.

I have picked them up at my local Tru Valu store. He has a good selection (even if they are really expensive!)

I've used Bolt Depot in the past https://www.boltdepot.com/Catalog.as...FdRyfgodHBMJgw

Not used these but they're out there...

You can also use the bolts from the Ninja Calipers - they are the same size. Lots of them available on Ebay.... I currently have six of the grey plated ninja ones in mine.

Thanks, Guys.

The bolts that came in my calipers are a tad too short, so I'm just going to reuse the two factory bolts, and then I picked up a third Stainless Rounded Head Hex-Drive bolt in M10-1.50 with a locking nut for the lower bracket to fork mount. Looks pretty good. I'll replace them when I can find the right ones. Weather is too nice to drag this out for weeks!

Hoping to have it wrapped up later this week.

Anyone have a solid source for the M10-1.25 Stainless, preferably Socket Head Cap Screws, for bolting on the brackets for this?

I can reuse the existing bolts for the calipers, but need to get a 3rd for the lower bracket mount, and would prefer they all match and look good.

Having a hard time locating suitable bolts in that size.

Yes as Mark says between the rotor & the hub.

Could you please remind me where the spacer at the wheel is supposed to go? On the inside or outside of the rotor?? (I'm assuming logically it's inside, but...)

Between the rotor and the wheel hub.

Nice! Get it done... Those are the 7 rivet F4 rotors. They are the lightest ones that work & just need the holes enlarging not completely re-drilling from memory.

Yes. I think I remember chatting with you about that and then trying to get the "best" ones I could.

FINALLY getting around to installing the new brakes on my 1980 GS850GT! I think Dan sold me the bracket kit back in 2015, but they've been sitting on the shelf.

Time to dive in!!

These are 1988 Ninja 750 Calipers and a set of Honda CBR F3 Rotors.

Good stuff. You just don't want it to make a thin edge that potentially cold break off & jam things up.

Yep! I shaved it down at a 45 degree angle. May have to do it again toward the end of the pad life, like you said. We'll see.

[salty_monk]

Nice! Did you chamfer the back of the pad material to where it hits the rotor? You should keep an eye on that as it wears, you may need to pop the pads out & do it again.

Single sided upgrade:



Works great!
