Sorry... not legal to do without certification. I know it seems a bit outlandish, but Wikianswers does not provide information on how to commit illegal acts. Couple that with you pretty much coming out and saying you don't know how, you really need to get hands-on with someone who does know, rather than just reading about it. Not to mention you didn't state what type of brakes you have.. for that model year, you might have either s-cam foundation brakes or wedge brakes.
As long as it takes. You didn't specify a model (remember, Kenworth makes Class 5 through Class 8 trucks), you didn't specify a brake system (S-cam air brakes, hydraulic brakes, hydraulic disc brakes, air disc brakes, air wedge brakes, or air piston brakes), and we don't know your level of technical experience.
brakes adjust themselves automatically
If the parking brake does not engage fully, the rear (shoe type) brakes need to be adjusted or replaced.
Depends on your technical proficiency, availability of the appropriate tools, and what type of brakes it has... I can do a set of S cams within an hour. Wedge brakes... I'm not as familiar with them, so it'll take me a bit longer. Of course, I'm a tech and I do this regularly... if you're not, it'll take you longer.
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.
You open up the steering column and find it in there...
You have drum brakes on the rear.
Jammed brake switch or short in the circuit.
What about 1993 Pontiac drum brakes, please be specific.
Drum brakes are meant to self adjust when applying the brake in reverse, however you can access the adjuster from the back side of the brake plate through a rubber grommet, it is hard to see but in there there is a little gear looking thing that you can manually turn with a flathead screwdriver to adjust the brake pads. If access is too difficult then you will have to remove the drum to get at it, im thinking that once you get in there you will find that it is pretty dirty which is causing the adjusters not to work, and the shoes are worn as well.
How do you adjust the parking brake on a1994 Lumina?
The towing capacity of the 1993 Mitsubishi Pajero depends on if the trailer is equipped with brakes. Without brakes, the towing capacity is around 1,650 pounds. With brakes, it ranges from 4,000 to 5,500 pounds
