Kenworth T600s have automatic slack adjusters, so to adjust the brakes do this:
Hook the tractor to a trailer and park it on a level place. With the engine running and transmission in neutral, push in both brake release valves. Wait about five seconds to be sure the brakes are released. Press the brake pedal all the way down slowly--count to five while you're pressing the pedal. When it's all the way down, take your foot off the brakes quickly. Count to five and press the pedal to the floor again, release, count to five and press/release the pedal a third time. This really does work.
If you spring brakes aren't holding, and you haven't backed your slack adjusters off manually or caged your brake chambers, then you have a defective component (or multiple ones) in the brake system. Get it diagnosed and repaired.By the way, the method described below is only applicable to adjusting brake stroke on automatic slack adjusters, which were not mandated until the 1994 model year - if you have a 1986 to 1993 model T600, you likely won't have auto slacks.
A Kenworth T600 can be purchased from a truck dealership and from Truck Paper, Truck Trader, Ranges Trucks and Accessories, Truck Sales, Ebay and Commercial Trucks.
It's 3 lbs, 12 ounces for the T660, and that's what it should be for the T600, as well.

Peterbilt never made the T600. The T600 was built by Kenworth, and it ended production in 2007, at which point it was replaced in production by the T660.
You open up the steering column and find it in there...
It'll be in the vicinity of 11 gallons.
Between 16,000 and 18,000, depending on options. For example, the engine displacement will affect weight. If you get, say, a C12 or C13 Cat engine, it'll be lighter than the C15 or Cummins ISX. The transmission.. an 18 speed will have more weight, etc.
The tallest point can be up to 13'6... typically, they'll be between 13'1 and 13'4 with a stand up sleeper.
Call a Kenworth dealership, give them the last six of the VIN. They should be able to tell you what it was keyed for from the factory - if it was re-keyed at any point, they won't know.
There are many types of semi trucks available for purchase from Kenworth Trucks. A few of these semi trucks are T880, T680, T600, T700, W800 and also a W900. Kenworth dealers will also sell used trucks from other manufacturers which were traded in. Aside from selling Class 5 - 8 Kenworth trucks, some Kenworth dealerships are also dealers of Hino trucks.
Call Kenworth with the last six of the VIN... that's the only way to know for sure. Not every single vehicle of that make and model will have the same requirements, nor will they even within the model year.
Air brake systems don't work that way - the brakes in that T600 have very little in common with the brakes on your personal car. There is no brake cable. That's an FMVSS-121 air brake system. The brake pedal is attached directly to the treadle valve, and the return is by air pressure (on some model years, there's a brake return spring to assist with this). Either you have a faulty brake return spring (if yours is a model year which has one), or else you have a faulty treadle valve. Fee free to email me at the address in my profile page and better describe the symptoms to me, and I can do more to troubleshoot the problem you're having.The cable that you're seeing which comes out of the hub and spindle assembly is not a brake cable - that goes to the wheel speed sensor for the ABS system.
