Push the palm release lever (A) on theparking brake handle (B) and push downas far as possible to release the brake.Driving with the parking brake on causesthe brakes to wear out quickly and reducesfuel economy.
We recommend you not use the parkingbrake to stop a moving vehicle. However,if the normal brakes fail, you can use theparking brake to stop your vehicle in anemergency. Since the parking brake onlyapplies retardation to the rear wheels, thevehicle's stopping distance increasesgreatly and the handling of your vehicle isadversely affected.
Releasing Spring Manually
WARNING: Do not attempt todisassemble the parking brake airchamber under any circumstances asthis may cause serious injury.
WARNING: Block the wheels tohelp prevent the vehicle from moving.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
If you release hydraulic pressure from thespring brake chamber, the power springapplies the brake. If the hydraulic pressurecan be re-established, you must releasethe spring brake in order to move yourvehicle.
Air Brakes (If Equipped)
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
If the service brakes fail to operate whileyour vehicle is moving, you can make anemergency stop with the parking brake.Since the parking brake only appliesstopping power to the rear wheels, yourvehicle’s stopping distance greatlyincreases and the handling of your vehicleis adversely affected. Make repairsimmediately to an inoperative air brakesystem circuit.
Pull the yellow, dash-mounted parkingbrake knob to apply the parking brake.

Releasing the Parking Brake
WARNING: When your vehicle isstationary, keep the brake pedal fullypressed when shifting gears. Failure tofollow this instruction could result inpersonal injury, death or propertydamage.
Note:Read and understand the followingsteps and perform them whenever youprepare to drive the vehicle.
Note:The parking brake does not disengageunless sufficient system air pressure isavailable.
1.Press and hold the service brake pedalwhile the engine is running.
2.Select the appropriate drive gear.
3.Push and hold the yellowdash-mounted parking brake knob untilthe parking brake light turns off, thenrelease.
Parking Brake Light Illumination Dueto Low Air Pressure
If the air pressure becomes too low at anytime during vehicle operation, the parkingbrake may apply and the parking brakelight turns on.
If the parking brake applies due to low airpressure, immediate service is required tothe parking brake system.
Releasing Spring Brake with AirPressure
The air system in all vehicles withspring-actuated rear wheel parking brakeshas a valve on the governor for connectionto an outside air supply. The valve lets yourecharge the system with air from anoutside source, releasing thespring-actuated parking brakes. Yourvehicle is now ready to tow in anemergency.
You can only use an outside air source ifthe protected system is in operatingcondition. If you cannot restore air pressurein the protected air system, you mustrelease the spring-actuated brakesmanually.
Releasing Spring Manually
Do not use impact wrenches as they maydamage the piston and prevent propercaging of the spring. Do not apply morethan 50 lb.ft (68 Nm) to the release boltnut.
1.Remove the stud tool and nut from thecarrying pocket on the brake chamberassembly.
2.Remove the access plug from the endof the spring chamber.
3.Insert the release stud through theopening in the chamber and into thespring pressure plate.
4.Turn the release stud ¼ turn to engagethe stud tangs with the slot in thepressure plate. Keep the stud engagedand install the nut on the release stud.

BRAKES
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake.
WARNING: You must remain inyour vehicle when the system turns on.At all times you are responsible forcontrolling your vehicle, supervising thesystem, and intervening if required.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
WARNING: The system will turnoff if a malfunction is apparent or if yourev the engine excessively. Failure to takecare may result in the loss of control ofyour vehicle, serious personal injury ordeath.
The system makes it easier to pull awaywhen your vehicle is on a slope withoutneeding to use the parking brake.
When the system is active, your vehicleremains stationary on the slope for two tothree seconds after you release the brakepedal. This allows time to move your footfrom the brake to the accelerator pedal.The brakes release when the engine has
developed sufficient torque to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
When the vehicle is on a slope, the systemwill turn on automatically to preventvehicle rollback.
Note:There is no warning light to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intogear when facing uphill or reverse (R)when facing downhill.
2.If the sensors detect that your vehicleis on a slope, the system automaticallyactivates.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away forabout two to three seconds. This holdtime automatically extends if you arein the process of driving off.
4.Drive off in the normal manner. Thesystem releases the brakesautomatically.
Note:When you remove your foot from thebrake pedal and press the pedal again whenthe system is active, you will experiencesignificantly reduced brake pedal travel. Thisis normal.

Trailer Air Supply and ParkingBrake Modular Controls (If Equipped)
The trailer air supply valve delivers air tothe trailer supply and automatically popsout, shutting off the trailer supply, ifpressure decreases to approximately 35 psi(249 kPa).
The parking brake controls the springbrakes on the tractor. When you pull theknob out, it causes the trailer supply valveto pop out, applying both the tractor andtrailer parking brakes. You canindependently release the trailer brakes bypushing only the trailer air supply valve in.
Initial Charge
With the air system completely discharged,both knobs (A and B) are out. When theair pressure reaches 70 psi (481 kPa), thetrailer air supply (A - red knob) may bepushed in and should stay in, charging thetrailer air system and releasing the trailerbrakes.
You can push in the parking brake (B -yellow knob) and supply air to the tractorspring brakes, releasing them.

Normal Driving PositionPush in both knobs (A and B) to supply airto both trailer and tractor spring brakes,releasing all brakes.
System Park
With both knobs (A and B) pushed in(normal driving position), the parkingbrakes for both the tractor and trailer canbe applied by pulling the parking brakeknob (B) out, exhausting air from thetractor spring brakes, simultaneouslycausing the trailer air supply valve to popout, applying the trailer brakes.

Trailer Charge
If both knobs (A and B) are out, and youwant to recharge the trailer while leavingthe tractor spring brakes applied, the trailerair supply (A) can be pushed in to rechargethe trailer air supply line. You can also usethis mode to park a combination vehiclewith tractor spring brakes.
Automatic Application
If both knobs (A and B) are pushed in andthe brake system air pressure is reducedto approximately 35 psi (249 kPa), thetrailer air supply (A) knob automaticallypops out applying the emergency orparking brakes on the trailer. If the trailerair supply (A) knob is manually held in andthe air pressure is reduced toapproximately 30 psi (207 kPa), a tripper
piston within the valve moves, exhaustingthe trailer air supply, applying the trailerbrakes. Further reduction of air pressure,while holding the trailer air supply knob in,causes the parking brake knob to pop outat 25 psi (172 kPa).
Actuation of Trailer Park (Emergency)or Tractor Bobtail Position
To actuate the trailer brakes only, pull outthe trailer air supply (A) knob. This appliesthe trailer brakes whether the trailer usesemergency or spring brakes.
You can also use this mode when thetractor or truck with trailer is used duringbobtail operation.
