Not a true hydraulic brake

These are still cable actuated brakes. The benefit of hydraulics is lost on these because they still need a brake cable to connect to the brake levers

"fly-by-night construction"
radwagon 4 upgrade

My radwagon 4 came with mechanical disk brakes and they stopped the bike but it always felt like a bit of an adventure when going down a hill with a stop at the bottom. Checked factory brake pads and didn't seem any reason to switch to a different pad due to wear. Ended up buying these hydraulic calipers. Very easy switch out to the new calipers, way less than an hour of work. Perfect fit, didn't use any of the associated extra parts that came with new calipers, reused old bolts and washers. Made a tremendous difference in feel and confidence in actually stopping. Well worth the time, effort and money.

What should I consider when choosing bicycle tires?

When selecting bicycle tires, consider the size, tread, width, durability, pressure, weight, and riding style. Choose a tire that fits your bike's wheels, is appropriate for the terrain you'll be riding on, is durable and puncture-resistant, can handle the recommended tire pressure, and matches your riding style.

What size bike tire do I need for my bike?

To determine the size of tire you need for your bike, you can look at the sidewall of your current wheel, which will have the tire size printed on it. The size will typically be expressed as a combination of numbers and letters, such as "700x23c" or "26x2.0". The first number refers to the diameter of the tire, which is measured in millimeters for metric sizes (e.g. 700) or inches for imperial sizes (e.g. 26). The second number refers to the width of the tire, also measured in millimeters or inches. The letter at the end indicates the type of tire (e.g. "c" for clincher)
If you're unsure about what size tires to get or have any doubts about compatibility, you can consult your bike's owner's manual or contact the manufacturer for advice.
