55.2-59 59 Disc brake conversion using Toyota parts

Your bracket drawing is looking better. I'd also put radii (like you did inside around the king pin boss) where your caliper mounting tabs are to reduce the chance of stress risers that can cause cracking. In addition, you said you were going to use aluminum for the brackets. I don't believe I have seen anyone do a kit like this with aluminum - it's always been steel. There are a lot of braking forces here. Have you considered that?

Quite right about the radii on the caliper mounts. They should also have radii. That is where either my CAD software won't allow me to do it, or its me not knowing how to do it. I tried to cater for that with the one annotation specifying "all corners" and will verbally instruct the laser cutters to add them.

I am NOT a mechanical engineer. I do have some electronic background, which is why I got this recommendation from a friend who is a highly competent, experienced, mechanical engineer. If it did not come from him, I would have disregarded the recommendation outright, but coming from him, I have no qualms accepting and implementing the recommendation.

Today I made a more accurate bracket as per the above design and consequently made a few changes. Here is the bracket I hope will work in all respects.

Having it made from 7075 Alu x 16mm thick.
