Super 16 brake install trouble

You are welcome and thank you for being able to follow my explanations of how stuff works and apply that to the goal you are trying to achieve. Always makes it easier.

It helped a lot having you explain how it worked. That made things much easier.

Some folks get pretty irritated when I ask them questions that are intended to get them to think about how something works and then they shut down because I am not just spoon feeding them pat answers. Like when I asked you how the fluid gets into the master bore from the reservoir and why it doesn't just go back into the reservoir when you step on the brakes.

Once you understand that principle, it makes everything else easier.

I am the exact opposite, I really appreciated the conversation and now have a much better understanding of how everything works.

Question. I recently replaced right front caliper (and had both rotors turned). I can normally lock up both front brakes with a hard stop in reverse. After replacing the caliper, I now only get the right side to lock up. Is the new caliper working better than the old one, or do I just need to rebleed the left side?

While I would love to be able to say that nothing to do with bleeding or air in the system can cause a pull ever gets old, I've said it so many times that it pretty much does. Nothing about bleeding, the lack thereof, or air in the system can cause a pull. The system is designed in such a way that the two front calipers have a common fluid path and the rear wheel cylinders have a common fluid path. In a common fluid path or container, it is impossible to have differential pressure. Any spot or location in the container will have exactly the same pressure.

Go do a few back to back fairly enthusiastic stops and cool down and try it again.

I will try that. These aren't special brakes. In fact I didn't even replace the pads. Just seemed odd for only one side to lock up.

What's odd is only replacing one caliper.

It started to lock up (pull and get hot). I flushed it, it worked for a while, then started acting up again. Should they always be replaced in pairs?

I don't know if it is mandatory. It is highly probable that the conditions that affected one side are present in the system and will affect the other side. Had you pulled the caliper and cleaned out the bore and seal area after removing the piston, it would likely have been fine. They are basic hydraulic cylinders with very little to go wrong that isn't corrosion or damage related.

I considered that. However, I think it was the same caliper that locked up on me 2 years ago. (Luckily, just after getting off of Black Bear pass.) Didn't feel like working on it, reinstalling it, and then possibly having to deal with it again, so I bought a new one.
I haven't got rid of the old one yet, so maybe I'll pull it apart and see what's up.
Thanks for the information. Sorry for the hijack.

You likely won't see much because it doesn't take much to get them to sticking.

While I've got your attention...
Is there any solution to the front bracket divots besides welding and grinding, or replacing.

I saw these clips come up in a google search.
