Well one good thing is that some cars have auto dimming rearview mirrors. I didn't realize my car had this feature until I drove one without one. I'm literally never blinded through it at night. It's nice to have.
Sometimes I feel as though I am a bit "neruodivergent" in that I am much more sensitive than others in a very significant and rather painful way....yet I do not have anything remotely like ADHD or autism, so I don't call myself it.
No, I do not at all meet the criteria of HSP either. My sensitivity is specific to interpersonal relationships, but does NOT involve the five senses.
When possible, I like to keep the hardware inside holes of the dismantled pieces instead of putting it in a baggie.
Not a great shot, but I have multicolor beans

What the heck? Another dingus!
It is interesting because I have both the owner's manual and the official factory service manual, and none of them mention brake hose swelling or it being a cause of sponginess. It tells me to look for cracking/deterioration, but that's it. There is a separate area with a zillion and one possible causes listed for spongy brakes, but interestingly degraded brake lines are not one of the listed causes.
Here's a screenshot from this part of the service manual:

But it is quite interesting to hear about braided steel cables. Seems a lot of people swear by them! I will definitely keep it in the back of my mind.
I do have rubber and plastic components that have degraded on my bike. So I know what you mean that at the age of my bike, stuff can start to go bad. Especially because I suspect this has always been an outdoor bike. The gas tank cap seal was aftermarket, but was cracked and degraded. The plastic clips that held the battery in place were degraded, etc. The speedometer now let's in moisture. Etc. There isn't any obvious degraded fuel or brake lines that I can discern from only a visual inspection.
I guess the problem I'm having with some of my issues (I have another one which is more of an annoyance than a huge issue) is that I can't readily discern the cause for them. I can keep pouring more and more money into the bike, but mechanical troubleshooting is so far beyond me that I'm afraid I'll end up making a money pit.
I've learned a lot of basic maintenance stuff this year that I haven't before. And I'm grateful to be able to do so. But it seems that I'm only really able to do general maintenance rather than extensive troubleshooting.
I only got my bike in the spring, but I'm contemplating trading it in for a new bike when 2027 models come out. Altho my big issue with that is I'm afraid of avoiding my warranty by doing my own maintenance. I'd rather do my maintenance myself. It's a tough call for me I guess.
Ok I tested a couple of times and I seem to be able to lock up the rear fairly easily. But the tires were prob cold. Can you easily lock them up with air in the lines still?
The front brake lever has some freeplay and then I hit a sudden wall of resistance, which to me seems fairly normal? I tried to do a bit of what you said but I am a bit nervous of being loud and potentially doing burnouts in my condo complex lol!!
The rear pedal doesn't have the same feel as the front lever. Instead of hitting a wall, I just feel a gradual increase in resistance until I can't push it anymore. It doesn't feel sharp like the front does for me and the pedal can travel fairly far. However, I cannot bottom them out unless I am bleeding the brakes and opening the bleeder valve.
I have heard of this! Interesting! Do you have to re-bleed the regular way after that? How messy is this lol?
What the actual fuck??? I've heard of air getting trapped in the ABS systems but I've never heard of it being paywalled. Fucking ridiculous.
My bike is fairly low tech! Doesn't seem to have anything like that. Doesn't even have a tachometer or gear shift indicator (and yeah no ABS).

Here is a schematic of my rear brake caliper.

Do you know what things I should be checking on here? I'm a bit lost as to how to troubleshoot this stuff.
No, I cannot pull the front brake lever to the bar when stopping hard. I can only do it when I open the bleed valve during bleeding. The rear brake lever doesn't seem to hit an obvious "wall" like the front one does tho. It just gains more resistance as I push down on it, but eventually I cannot push it down any further (unless I open the bleed valve). I think the rear brake may actually be "soft", but the front brake is probably fine.
Unfortunately that's the problem. I don't have a bike to compare to. This is my first bike and I've been riding it since around May/June. It was the mechanic who said the brakes were spongy. I took a couple day MSF course a while back but I can't remember much about the differences in the brakes other than the MSF bike (brand new) felt more sudden to stop...but I also didn't have fine motor control yet for the controls.
