Template caliper mount

Has anyone any printable template for making a couple of braking mounts? (Front and back)
Even a photo with any sort of object to replicate the general dimensions?

The dimensions for disc brake mounts are all available online.

I think I found the solution.
I bought a couple of adapters that came up with a sort of clamp. The adapter itself measure 4mm and it is made from stainless steel.
I was thinking to remove the clamp and gave to a professional who can solder directly into the frame and fork.
At least I cut the cost and also the time to find a piece of steel and making the piece itself.

​​​​​​Probably I'm going to reinforce them a bit too....

Okay, the mounts themselves. Don't think anyone has ever released such a thing.

They apparently wanted a design for a mount, not just the dimensions. Maybe there is one on an old website from back when everyone was converting their mtb to disc

This is good, I wish I had sooner...
I'm going to print and keep those anyways, they will came very handy in the future.
Thanks a lot

We all know there is no "one size fits all" design for weld on brake mounts. The generic ones, available from many framebuilding suppliers, always need to be fitted to the frame.

if the fork was not designed for disc, it may not be strong enough.

This seems like a job for FreeCAD and Send Cut Send. Even ordering just 1 of one's own design isn't much more expensive than the regularly available ones from suppliers. Add fancy stainless washers and you'd have a really nice ISO brake mount.

I'm not sure if Europe has a send cut send. But I do see builders on insta who sell laser cut framebuilding stuff, so it might work out.

Unfortunately, fork mounts for flatmount brakes requires 3d machining. Maybe SLS 3d printing?

Fork flat mount only requires the ability to drill and tap an M5 hole into a 1/2" round bar (and the ability to fit and weld it to the fork).

Thank you! This is exactly the information I needed!

I'm working on a bike trailer and needed this information. This is brilliant! You saved me so much searching so I signed up to say thank you! Cheers from Vancouver Canada! 🤗
Having trouble saving. One more try ...

Welcome to the forum. I usually go to the PVD wiki for info like this.

In my case, I'm looking at making a plate out of flat aluminum I can weld to the 1" square tube frame. I'm a bit rusty from my mechanical drawing days. Getting back into it for this project so please forgive me if I'm not understanding. I'm not sure if I will build from seat stay or chain stay reference, but ideally I will be able to accommodate my frame above or below the axel and caliper (1" / 25mm square tube).

When I'm looking at your Seat Stay drawing I interpret the drawing this way:
  • Middle drawing, I need 7-8mm flat material. Easy peasy.
  • Angle "I" seems to be missing (and important) as is dimension E...
  • Are these measurements for 160mm or 180mm rotors?
Can anyone help me fill in the blanks?

Thanks in advance 😃

What or where is the PVD wiki please? Google didn't help. Got into a lot of vapor deposition stuff 😂 thanks!

I should have checked it first before I recommended it. It's at https://www.peterverdone.com/ but it seems like he has been hacked. If you go to a random page, it's someone trying to sell gift cards.

These dimensions are for an IS (international standard) mount, which no one make a direct mounting brake to fit. You must use an IS to Post Mount adapter and they are made to adapt from 140mm to 200mm rotors using the same IS mount on the frame.

Dimension E is for clearance for the brake caliper and is dependant on the caliper used. The specs call for anywhere from 3.5mm to 6.5mm depending on the caliper. More clearance is better and is not going to affect the performance of the brake.

Dimension I is the max. angle for the mount I have never paid any attention to it. The specs call for a max. of 201 degrees, but anything with a tighter angle than that would't really function as a seat stay very well.

The mount does not have to be 7-8mm thick. Most of the comercially made mounts are 5mm thick.

His blog posts are fine, the wiki is all messed up. I guess he left editing wide open
