I thought they fixed that leak. 
IDK....Could be there's a new one. I definitely don't want to keep charging it every couple months. That's seems like a rather environmentally unfriendly thing to do.
Anyway, the hot weather appears to be done for now, so that gives me a little time to figure out my next move.
I guess I could charge it myself once, and see what happens. Maybe see if there's some sort of sealant I should run through it first. And check and see if that little gasket/valve thingie the guy showed me is cracked or loose or whatever.
The task itself is usually straightforward, however, there are plenty of useless kits for the task on the market and then there is the hassle of environmental issues.. I would rather pay for it. As far as the leak goes, there are fluorescent dyes you can add that reveal any leaks in the system.

Sorry for delay - company in r/l....
Nope.
Reason - does not apply on older vehicles with drum.brakes.
Uneven torque on the wheel hub can warp disc brake rotors. Disc rotors must run true within .0001 of an inch or so - or you will get pulsing in the brakes - and wear things out quickly
...
Yes, we went over this.

But torque is measured in weight. I suppose I could have said pressure or force, but that's not how I hear it referred to. *shrugs*
Torque is measured in foot-pounds, weight is a function of mass and gravity, torque isn't.
Colloquially, the concepts are similar, but they're not the same thing. I knew what you meant, though.

Torque can also be measured in degrees.
.....
Some bolts are torqued to a primary starting spot either in foot pounds - or slip capture (feeling a calibration washer's ability to be spun by hand) - then torqued to a measured turn of the bolt. Testing showed this is a more accurate method than ordinary torque wrenches.
I built parts for the service tool (Kent-Moore) for torqing the head bolts on GM's quad four engine.
I have one in my tool box.

No, proper torque conceptualized in physics can not be expressed in degrees. If you have a torsion spring with a known spring constant, it is possible to deduce how much torque is being applied by how many degrees the spring has twisted. But that is not the same thing as saying torque is expressed as degrees any more than the power of a car's engine may be reflected in how many miles an hour the car can go, but power of the car's engine can not be expressed in miles per hour.
Torque can be thought of as the amount of oomph you put into twisting something around an axis of rotation. Degrees is how much you've succeeded in twisting something about an axis of rotation.
It is never good to try to learn basic concepts in physics using English units because English units try to shoehorn sharp and precise concepts into terminology conceived of during an earlier age of nebulous confusion, when weight, mass, and even force seemed much the same thing.
If you use metric units it becomes much more clear what is going on. Torque in Metric is Newton-Meters. Newtons is a unit of force. Torque of one Newton-meter is the amount of twisting oomph that occurs at one end of a 1 meter lever arm when you apply a force of one Newtons on the other end of the lever arm. If you apply twice the force, you get the same ommph with half the lever arm length. Mass is the amount of resistance stuff has to changes in the direction and speed of its motion. The effort to change the direction and speed of the motion is force. Unit of mass is Kilograms, and unit of force is Newtons. Weight is the force required to resist changes in direction and speed of motion of object under gravity. Since weight is force, units of weight is also Newtons.

I suppose twisting injury hurts more than blunt force injury, for the same amount of force involved.
