DEMCO MODEL DA10 BRAKE ACTUATOR
INSTALLATION
Model DA10 is completely assembled and ready to bolt into place.
1. DA10 actuators come with various mounting channels available.
2. Connect and tighten all brake lines.
3. Fill master cylinder (#18) with DOT 3 or 4 brake fluid.
4. Bleed brake system using a pressure-type brake bleeder or manually, as follows:
a. Remove two 5/16" hex head bolts (#13) and lock washers (#12) that hold lever guide
(#23)and flat emergencyleverspring (#11). Removeleverguide and emergencyleverspring.
Using short strokes, pull forward on emergency lever (#16), pumping master cylinder until
brake fluid within master cylinder stops bubbling.
b. Attach a bleeder hose to bleeder valve on one of the wheels and submerge other end of hose
into a transparent container partially filled with brake fluid. Loosen bleeder valve one turn
and, watching hose in transparent container, use emergency leverto pump master cylinder
as long as air bubbles continue to leave the hose. When bubbles stop, close bleeder valve,
movetonextwheel,andrepeatprocessuntilallbrakeshavebeenbled.(Note:Checkfluidlevel
in master cylinder frequently while bleeding brakes (every 4 or 5 strokes). Refill as necessary
to keep level above half full.)
• Review all of the following instructions before installation and use of hydraulic brake
actuator.
• Dealers or Distributors must review these instructions with ultimate user.
• Failure to follow these instructions, or failure to properly maintain braking system after
installation, can result in loss of braking action which could cause severe property damage,
personal injury or death.
To Prevent Serious Injury Or Death:
Do not weld on the outer case without disassembling actuator, damage
to inner slider tube will occur.
To avoid personal injury or death, do not exceed lowest of (1) the rated
capacity of Model DA10 actuator, or (2) rated capacity of ball and hitch
being used, or (3) trailer's Gross Vehicle Weight Rating (GVWR).
Model DA10 brake actuator has a maximum load rating of 10,000 lbs.
GVWR and 800 lbs. tongue load.

MAINTENANCE
1. Frequently check brake fluid level. (Fluid must be approved, clean and uncontaminated.)
2. Make sure actuator mounting bolts are secure.
3. Inspect actuator, replace bent, worn or damaged parts.
4. Be constantly aware ofsystems brakingquality, makeperiodicchecksasdescribed in brakes owners
manual. Consult certified brake specialist to make necessary adjustments or repairs. Failure to do so
could result in loss of braking.
SERVICING THE EMERGENCY LEVER
If emergency lever (#16) of actuator is applied, it can be disengaged by using a screwdriver to lift
upward on front of flat emergency lever spring (#11) while pulling lever forward until released.
Athoroughinspectionofemergencylever,emergencyleverspring,andcablewithS-hooksisrequired.
Damaged parts must be replaced as follows:
a. Remove Cable S-hook (#22) from emergency lever (#16), emergency lever guide (#23) and flat
emergency lever spring (#11), then pull lever out of actuator outer case (#7) through cross-slot in top.
b. Install new emergency lever through cross-slot in top of outer case. Attach new emergency lever
spring and emergency lever guide.
c. Insert S-hook on emergency cable (#22) into hole in emergency lever (#16) and squeeze shut.
d. Add adequate brake fluid to master cylinder and bleed brake system per instructions 4-6
in installation section.
5. Oncebleedingis completed, refillmaster cylinder andattach cap(#21) securely. Replace
emergency lever spring, lever guide, lock washers and 5/16" hex head bolts.
6. Test brakes by pulling emergency lever (#16) forward until it locks into its second notch
position.(Levershouldbeapproximatelystraight up.) Attempt to rotatewheelsinaforward
direction. If any wheels rotate, brakes must be adjusted. To adjust brakes, release
