Topic: pictures of K1 dual disc caliper mounts

[Rookster]

Put a finishing nail in from the inside so the head catches the seat.  Chuck the nail up tight into a vice and drift the caliper off the seat.  Be ready to catch the caliper or have it fall into a rag.  I never had any luck trying to pull the seat out of the caliper with vice grips or pliers on the nail.

I’ve always used a drywall screw

Shtone, I have only done this once but it worked perfectly and was surprisingly easy...  Get yourself a drywall screw and gently thread it into the hole in the seat.  It does not need to screw in very far and don't ram it in.  Put your caliper in a vice and rig up a wood block or something so you can grab the screw with some plyers and lever the screw out on the block.  Mine popped right out easier than expected.

Frank also used a finishing nail, but I think he bent it 90* to keep the vice grips from slipping?
I've used the screw method, with a pair of needle nose pliers under the screw head to lever out the seat, but it can bugger up the seat a little bit if you're not careful, while the finishing nail won't.

thank you, everyone.

Phil had a operating shop for 50 plus years and he has never done this before or knew that you could, he also never had an interest in dual disc applications so it kinda makes sense. I just thought it was funny to have so much experience and still find things he hasn't done yet, big or small.

Bringing this back from the dead because Im curious about this set up with a stock fender?

If the bosses are removed how do people mount the fender?

Anyone have pictures of dual disk with C clamp style caliper arms and a stock fender installed,?

[Shtonecb500]

never mind, I found some pictures on google and I see how you guys do it now.

thank you for reading.

You might like to read through this link on when I did the twin disc conversion on my K2, which has the same brackets and more or less the procedure to go through:  https://www.sohc.co.uk/index.php/topic,21171.0.html

+1.

Checkers Flag Customs(Yoshimura) sold the custom magnesium right side C brackets for the early fork lowers(69-71) a long time ago.

Modifying the factory left side bracket into a right side bracket is the normal method.  I can take pics of a geniune CFC right magnesium side bracket if that helps you, but no, mine is not for sale.

I kind of buggered the brake line seat, its not a perfectly shaped tapered cone anymore, will it still work or is it just gonna leak? I think I used too large of a screw.
Here's a couple three pics of a CFC bracket. It was designed to be used with the stock fender brace, which fit between the bracket and fork leg. If the fender brace wasn't used, washers were needed or the caliper would sit crooked. Also, the brake line seat needs to be removed and reinstalled in the old bleeder hole to convert the caliper to right side use.
edit: found another pic of the CFC bracket and one of the flare seat.

I tried once, it was corroded in, had to buy a new one.

I found this video and thought I would share, they cover removing the brake line seat incredibly well. This is a step by step dual disc installation for any K2 and on.
