Consumer - Read and follow these instructions. Keep them with the trailer for future reference.
INTRODUCTION TO SURGE BRAKING
Surge braking is accomplished by replacing a trailer's standard tongue coupler with an actuator and adding hydraulic
brake assemblies. The "surge" or "push" of the trailer toward the tow vehicle during deceleration automatically
synchronizes these trailer brakes with the tow vehicle brakes. As the trailer pushes against the vehicle, the actuator
telescopes together and applies force to its master cylinder, supplying hydraulic pressure to the trailer's brakes.
Surge actuators of this type provide a service life of approximately five years with proper installation, usage, and
Maintenance. However, a well cared-for actuator can often exceed this estimate. To get the most benefit from your
TITAN surge actuator, follow the instructions given in this manual and use common sense in caring for the TITAN
AERO 7500 actuator and your entire trailer brake system.
7,500 POUNDS MAXIMUM GROSS LOAD (weight of trailer fully loaded with all cargo and equipment). To find your
trailer's Gross Load, use a commercial vehicle scale at a truck weigh station, grain elevator, etc.
700 POUNDS MAXIMUM TONGUE LOAD (weight applied downwards by the fully loaded trailer's coupler onto the tow
vehicle's hitch). Measure your trailer's Tongue Load with the tongue in the horizontal towing position, using either a
commercial scale or a bathroom scale if the load is small enough. Upwards tongue loads are not permissible.
The AERO-7500 actuator is intended for use on recreational, marine, and agricultural
occasional-use trailers, which are towed by passenger cars or pickups. Use ONLY with
a two inch (2") diameter tow ball. The actual in-service rating is limited to that of the
ball and hitch being used or the trailer manufacturer's G.V.W.R. shown on the
certification label, whichever is lower.

Summary of Contents for Titan AERO 7500
- Page 1 However, a well cared-for actuator can often exceed this estimate. To get the most benefit from your TITAN surge actuator, follow the instructions given in this manual and use common sense in caring for the TITAN AERO 7500 actuator and your entire trailer brake system.
- Page 2 INSTALLATION The AERO 7500 Actuator is completely assembled and ready to bolt or weld into place onto straight three inch wide trailer tongues. Welding will make repair or replacement difficult but may be preferred. If the actuator must be painted for aesthetic reasons, then TITAN recommends painting ONLY the outer case and disassembling the unit prior to painting.
- Page 3 INSTALLATION (cont.) Brake Fluid Filling and Bleeding Fill the system with DOT 3-4 heavy-duty brake fluid. The braking system may be bled manually or with a vacuum or pressure type brake bleeding system. Both types of brake bleeding equipment should be available at your local automotive jobber.
- Page 4 TESTING TITAN SURGE BRAKE SYSTEMS Hydraulic surge actuator systems provide automatic and smooth trailer braking without special application by the tow vehicle driver. While this is extremely convenient it can sometimes be difficult to determine if the surge setup is functioning properly.
- Page 5 The hitch MUST be installed so the trailer tongue is level (horizontal) when coupled to the tow vehicle. The AERO 7500 MUST be used ONLY with a 2” diameter tow ball. To attach the coupler to the tow vehicle, lift the actuator handle fully, approximately thirty degrees (30°), to allow the ball latch to rotate to its open position.
- Page 6 HITCHING TRAILER (cont.) Attach the actuator's break-away chain S-hook securely to one of the tow vehicle hitch's safety chain connection points (see Figure 3). Confirm that the trailer's safety chains are adjusted relative to the actuator's breakaway chain as noted above. DO NOT loop the breakaway chain around a bracket and hook it back onto itself.
- Page 7 BRAKE LOCKOUT MECHANISM When your Aero 7500 is used with disc brakes or non free backing brakes, there are two alternatives to allow normal backing of your trailer. Our solenoid back up valve < 4748800 > is a convenient choice. It is electrically activated when the tow vehicle is shifted into reverse and prevents brake fluid from flowing to the trailer.
- Page 8 Free-Backing brakes by rotating in forward direction only. Failure to adjust may result in loss of braking. Before storage or after extended use, TITAN recommends applying motor oil to the coupler components, lockout mechanism, and the three internal rollers to keep them moving freely and to prevent corrosion.
- Page 9 AERO 7500 ASSEMBLY Over time, you may need to disassemble your TITAN Aero 7500 for service or to replace components. Use the following steps to put the actuator back together, checking this manual's assembly diagram and parts list for reference.
- Page 10 AERO 7500 ASSEMBLY (cont.) The master cylinder <6> and pushrod assembly components <13> can now be assembled. Apply a light coat of brake fluid to the small opening of the rubber boot on the front of the master cylinder. This will ease assembly and reduce the chance of damaging the boot.
