SECTIONBrake Action Tandem TrailersTongue-TowedHubs& AxlesInformationCCorrect InstallationCouplersJacks &WinchesTires &WheelsSuspensions& FastenersBrakeAssembliesIncorrect InstallationTongue towed trailer require brakes on all 4 wheels of tandem axles for maximum braking. However, some tailer manufacturersmount brakes on only two wheels of a tandem. To determine whether the brakes should be mounted on the front or rear wheelsof the tandem requires a study of the physical action on the torque exerted when the springs have an equalizing shackle betweenthe front and rear axle.When the brakes are on the front wheels , the turning torque tilts the shackle to its upper limit, reducing the load on the front wheel andincreasing the load on the rear wheel. This action causes the front wheel to skid more readily, reducing effective braking of the vehicle.The sketch below shows an exaggerated condition of the above explanation. It is our opinion that when brakes are installed on only twowheels, they should be mounted on the rear, rather than on the front of the tandem assembly, using an equalizer shackle mounting.Free Backing BrakesAllow you to back up with the Surge Braking SystemAs wheel revolves forward, outward movement of shoelever engages brake shoe with drum providing full braking action.As wheel moves in reverse, shoes turn with drum untillining pressure is released. Hydraulic pressure is contained by the cylinder.SwitchesBrakeActuatingSystemsLocks &Cargo ControlLights &ElectricalTrailer PartsBodyComponentsHitches &TowingAccessoriesHere’s the way it worksC2NOTE: Free backing brakes are not effective in reverse
SECTIONCInformationHow to Select Electric Brakes & Brake PartsActuation ArmHold DownSpringsCouplersJacks &WinchesHitches &TowingAccessoriesDetermine the manufacturer of your brake Select the brake you have by looking at the keyidentification points shown in the drawing Check the electric brake chart for your brake andthe part you need. Further identification may be madeby referring to the exploded drawings and magnet photosof each brakePrimary Shoeand LiningSecondary Shoeand LiningAdjusterMagnetUsing The Electric Brake ChartBrakeActuatingSystemsSwitches Worn, weak return springs will cause the brake linings to drag against the drum and cause prematurebrake failure. Hold-down springs will lose their tension and allow the brake shoes to wobble or ride up against the faceof the brake drum, causing premature lining failure. A frozen adjusting screw will not allow shoes to be adjusted properly. Rubber dust plugs will crack with age and allow dirt to contaminate linings. (Not shown.) A stretched self-adjusting cable prevents the self-adjusting lever from properly aligning the shoes.(Not shown or illustrated.)Locks &Cargo ControlReasons Why Brake Hardware Should Be ReplacedLights &Electrical Find the picture that matches the assembly or the part you need. The part and reference numbers are just below the picture of your assembly or part. Part and referencenumbers are placed beside the photo of individual replacement parts.

To determine the right or left side brake assembly, position the brake with the magnet at the bottom. Onelectric brakes, the actuating arm will always curve from the pivot pin to the magnet, toward the left for lefthand brakes and toward the right for right hand brakes. (See the illustration.)2. When ordering your brake assembly or brake replacement part, always use both the part number and thereference number. Both are necessary to insure prompt and correct filling of your order.3. Sometimes the easiest, most economical way to repair a brake is to replace the complete assembly. Byremoving wires and a few nuts and bolts, you have all new parts, saving time, trouble and expense.4. Whether you choose to replace the entire brake assembly, only individual parts in need of repair, or neednew brakes to build a trailer--We have what you need to do the job right! We are just a telephone callaway.C3
SECTIONElectric Trailer Brake Part IdentificationManufacturer IdentificationAL-KOAL-KO levers are very flat. The brake shoes do not have anything unusual about them. AL-KO uses only one return spring atthe top on both 10 and 12-inch units. With the drum off, you can tell what size the system is if the magnets have never beenreplaced. The 10-inch brake will have a magnet with light green wires and the 12-inch brake will have white wires.DexterDexter uses a stamp on the back of the backing plate that identifies the size of the brake. Looking on the back side you will seea triangle. Around the triangle you will see Dexter and the size (i.e. 10” x 2-1/2” or 12” x 2”). Dexter uses 2 return springs onall late model brakes; some early 12-inch brakes used a single return spring.HayesHayes brake shoe webs have a tooth that hangs down at the top and use a single return spring. Early 12-inch brakes used a dualreturn spring. Hayes axle is owned by AL-KO. AL-KO backing plates have been seen on some of the new Hayes axles. It looksas if they are still using the Hayes name and are starting to use AL-KO parts.FayetteFayette axles are obsolete. If you find a Fayette axle tag and the trailer is worth keeping you should consider changing the axlesto AL-KO or Dexter. At that time it is recommended that the spring hangers and bushings also be replaced.Tires &WheelsSuspensions& FastenersBrakeAssembliesHubs& AxlesInformationCAxle IdentificationAxles generally have an ID tag located on the axle crossbar that gives you the axle capacity. Check therefirst. This would give you a starting reference point.Brake Drum / Shoe SizeMeasuring is the same for all brands. Using a tape measure you can do a random measurement as to thediameter by measuring across the drum. If it is a 10-inch drum you will measure approximately 11 inchesacross for an outside measurement. The 12-inch brake will measure approximately 13 inches for an outsidemeasurement. The drum would need to be removed to get the correct diameter and width.SwitchesBrakeActuatingSystemsLocks &Cargo ControlLights &ElectricalTrailer PartsBodyComponentsHitches &TowingAccessoriesCouplersJacks &WinchesBrake Size IdentificationC4Magnet Identification(Magnets can be identified by the color of the wire used)Dexter7” x 11 4”The magnets are round.

The brakes should be adjusted in thefollowing manner:BodyComponentsINOPERATIVE BREAKAWAY SWITCH Check for dead or weak 12-volt battery, on trailer. Check all wiring and connections. Check breakaway switch. If only one brake is operating, check other magnets.Hitches &TowingAccessoriesUNEVEN TIRE WEARPossibly due to: A bent or misaligned axle, Improper tireinflation. On tandem axle trailers, check voltage at front axleand rear axle with brakes applied. At times, the front axle will“lift” allowing front wheel to lock and slide. Correction can bemade installing magnets with even resistance.CouplersJacks &WinchesBRAKES LOCKED, BRAKE PEDAL NOT DEPRESSED Check stoplight switch adjustment. Check for short between stoplight switchcircuit and power supply circuit. If brakes are locked when 4-way flashers are operated,check for Pulse Preventer installed in circuit. Check breakaway switch (pulled).Tires &WheelsGRABBING OR LOCKING BRAKES Check for improperly installed flanges. Check for contaminated brake linings (grease on linings).
