I came across this photo the other day and thought some of you might be interested to see it. It's the brake assembly for a DeHavilland Canada Dash 8-100. There are three discs and six pots. The hydraulic line connects where the silver plug is at the bottom of the photo, and the black fitting on the left is the bleeder port. The two pins at the top and right side of the photo are the wear indicator pins.

When the pads are worn, the whole thing is replaced as a unit.

One of these assemblies goes on each one of the four main wheels.

Here is a picture of one of the planes.

Sweet. At first glance I was like "What kind of witchcraft-powered car uses this?!" lol.

And do you know the cost per unit? Thanks for sharing.

I don't. I just got one from the parts counter guy when I needed a new one, lol.

I had a conversation with another aerospace engineer friend of mine one day where I posed the question: what's the single most impressive part on an airplane?

We both agreed on the brakes. These things stop massive amounts of weight from high speed safely and reliably. They are truly amazing.
