Can I purchase trailer parts and accessories directly from Tie Down Engineering?

No, Marine Aftermarket products are sold to wholesale accounts only. Retail customers wishing to purchase our products can purchase them through most marine retailers, national retailers and select internet based retailers.

Can I buy axles directly from Tie Down Engineering?

No. TDE builds axles for OEM trailer manufacturers. We do have several trailer parts distributors that sell what they consider ‘stock” or common sizes. Should you need a replacement axle, contact your trailer manufacturer or a trailer parts supply company.

Is it necessary to tow a trailer level?

Yes, especially with multi axle trailers. Spring axles have some forgiveness with the equalizer between the springs. Torsion axles do not have this feature and towing an un-level torsion axle trailer places most or all of the trailer weight on one axle. This will lead to premature tire wear, loss of braking power and possible axle or trailer damage.

How often should I grease the bearings?

The standard we use is every 12 months or 12,000 miles whichever comes first.

What is “Super Lube” and how does it differ from the “Bearing Protector Caps”

Super Lube is TDE’s brand of grease lubrication that changes the grease in the hub as you add new grease. Super Lube comes in two versions.

  1. This spindle type has a grease fitting under the wheel cap on the end of the spindle. Grease is pressured into the fitting and travels through a drilled hole in the spindle and exits under the rear bearing. This pushes the old grease outward through the front bearing and out the hub. Super Lube provides new grease for both the front and rear bearing without pressurizing the hub.
  2. Super lube is also offered on specially machined hubs with a grease fitting on the rear of the hub. The Super Lube hubs allow you to have this great feature on axles that were not drilled for the Super Lube lubrication.

“Bearing Protector Caps” offer a grease fitting on the outside of a spring loaded dust cap. New grease is pushed into the hub from the front side only. This does provide an easy way to pack grease into the hub on trips. However, since the rear bearing does not get to see this new grease, we still recommend repacking the wheels every 12 months or 12,000 miles when using this type of lubrication system.

Can brakes be added to an axle that does not have brakes?

Yes, if the axle has brake flanges welded to the axle. This is a metal plate with four holes for 10” brakes and five holes for 12” brakes. It is not advisable to try to weld these on. The brake flanges must be straight and 90 degrees to the spindle. If they are not “square” to the spindle, the brakes will not center in the brake hub or rotor and create wear problems.

How often should I adjust my hydraulic drum brakes?

New brakes should be adjusted after a break in period of 150 to 200 miles. After the break in period adjustment drum brakes should be adjusted every 3,000 miles. If you are experiencing brake chatter at low braking speeds, this could be an indication of needing to adjust the brakes.

How often do I adjust my disc brakes?

One of the many advantages of disc brakes is that you do not need to adjust them.

I have a dual axle trailer with brakes on only one axle. Do I need brakes on the other axle?

As a safety concern, TDE always recommends brakes on all axles. DOT requirements for trailer brakes combine the tow vehicle and trailer in the stopping equation. The tow vehicle and trailer are required to stop in a predetermined distance. Needless to say, the type of tow vehicle used can affect this requirement. State laws also come into play. Many states require brakes over certain weight capacities other states have minimal requirements. Remember, any brakes are better than no brakes.

Why can’t I use DOT 5 Brake fluid in the Tie Down Brake system?

DOT 5: This brake fluid is based upon silicone. Its dry boiling point (ERBP) is 260°C minimum and wet boiling point is (Wet ERBP) 180°C. It is used in applications, like for weekend, antique, collector cars that sit for long periods and for some military vehicles. Some car manufacturers use it in their road driven vehicles. Systems designed for DOT 3 fluid may use rubber parts that will be adversely affected by silicone based fluids. This brake fluid does not mix with DOT 3, DOT 4 or DOT 5.1. It absorbs more air and giving poor pedal feeling. It is unsuitable for racing due to more compressibility under high temperatures. If as little as one drop of water enters the fluid, severe localized corrosion, freezing or gassing may occur. This can happen because water is heavier and not mixable with silicone fluids.
