Dexter Nev-R-Adjust Electric Trailer Brakes

Nev-R-Adjust Trailer brakes

Nev-R-Adjust Trailer brakes

Electric drum brakes (10” and 12”) are the norm for most trailers rated less than 15000 lbs. These brakes have always been considered cantankerous because of the problems caused by brake lining wear. This normal wear requires periodic adjustment of the brakes that may or may not be performed. If not performed, the trailer could lose as much as 50% of the potential braking power. With the lost trailer stopping power, the tow vehicle has to over-work its brakes.

So says Dexter Axle as they have developed a solution to this problem in their new line-up of trademarked Nev-R-Adjust electric drum brake assemblies. They have used technology already available in heavy-duty truck and trailer brakes and adapted it to the smaller 10 inch and 12 inch electric brakes found on most RVs, utility, horse trailers etc.

Dexter accomplished this self-adjusting feature by adding a 9 piece “Adjuster Kit” to the standard brake assembly backing plate. This allows the brake assembly to constantly adjust the lining position as the brake drum turns during trailer operation. In speaking to Dexter’s Engineering team, the adjustment feature works as the trailer moves in both forward and reverse directions but the increments of adjustment are much higher in reverse. Since there are specific brake assemblies designed for the driver-side and curbside of the trailer, problems will occur if the brake assemblies were installed on the wrong side of the trailer. Brake assemblies mounted on the wrong side will act like they are traveling in reverse. This would cause “over-adjustment” and can cause the brakes to overheat and lock. Therefore, for self-adjusting brakes, it is imperative that the proper brake assemblies are installed on their specified side of the trailer.

Dexter introduced their 12 inch self-adjusting brake assemblies in May of 2008 and their 10 inch unit in May 2009. They performed extensive reliability testing using a dynamometer and also real life testing on their own trailer fleet before they marketed the product. They offer a 2 year limited warranty on these products.

It seems that recreational trailer owners have been the first to embrace this new product offering with more commercial trailer owners loyal to the standard product. The new self-adjusting brake assemblies cost about 20% more than standard brakes.

Trailer Axle Camber

Trailer Axle Camber

There are several different parameters that are very important to finding a new axle for a trailer. The most obvious is the Gross Axle Weight Rating that defines the load properties of the axle (and trailer). Typical values of GAWR are 2200 lb, 3500 lb 5200 lb etc.

Other values that are important in defining a trailer axle are Track Length (center of tire to center of tire), Overall Length and Spring Center (center of spring to center of spring).

Camber is another property that is defined by the trailer axle. Actually, camber is the effect of the tire alignment on the pavement as illustrated above.

Most trailer axles are designed with a “bend” in the tube that will deflect when the load (weight of the trailer) is applied. This will theoretically bring the trailer wheel camber toward a 0 value that is the best setting for most trailer applications. This will allow the tires to wear evenly and allow the longest tread life. Camber can be affected by damage to the axle. For example, if the axle spindle is bent, this will usually cause a negative camber on that side which will cause excess tread wear on the inside of that tire.

Both Sprung axles and Torsion axles typically are built with a slight positive camber but custom axles can be specified with or without camber. A trailer that runs long distances without a load may be better without axle camber. An example of this might be a long distance boat transport trailer.

Boat Trailer Parts

Boat Trailers are different from other types of trailers and RVs because they get immersed in water (often salt water) and that accelerates corrosion or rust. A definition of corrosion is “development of metal oxides on the surface of a metal part”. With steel as the metal, iron oxides are the compounds that form rust (Fe2O3/FeOOH). Rust starts on the surface but if not corrected, will corrode the part until it fails. If this happens, the part will need to be replaced. Finding parts for specific brands of boat trailer is not easy because many manufacturers have closed their operations years ago.

The traditional method to help retard corrosion in boat trailer components is to galvanize using hot dip zinc. Zinc electro-plating will help but due to the plating porosity, corrosion will gradually erode the part. Aluminum is also frequently used as a material.

Eastern Marine specializes in replacement parts for boat trailers. Just about any part you need is available including axles, leaf springs, brakes, winch post parts, etc. If you have a Load Rite trailer; then select LOADRITE Factory Trailer Parts. If you have an EZ Loader trailer, select EZ-LOADER Factory Trailer Parts .

It a few weeks we will be offering a new product line that will be of interest to owners of older boat trailers… the galvanized square tube universal axle. These 2” x 2” axles will be supplied by Tie Down Engineering and be available in 2000 lb rating (up to 96 inch overall length) with a 1-1/16” straight spindle. The 3500 lb axles will also be available up to 96” overall length with a standard 1-3/8” x 1-1/16” spindle with brake flange. What makes them universal is that the customer will have to drill holes in the tube for the spring seat position exactly as it is on the axle being replaced. This position varies for each trailer manufacturer. We would recommend treating the drilled area with a corrosion preventive product.

This new product will be just the ticket for owners of discontinued trailer brands like Calkins, Cox, Shoreline, Holsclaw, Escort, Long, Dilly, Performance etc. and can be seen at TRAILER PARTS SUPERSTORE


Fulton Trailer Lock

Unfortunately, we have many customers relate stories of their trailer being stolen. Often, the trailer is loaded with valuable tools or favorite toys like boats or snowmobiles etc. One particularly disturbing incident involved a trailer owned by a Boy Scout troop where they lost all their equipment. There are many options available to trailer owners to reduce their risk of theft. I want to review some of these in this article.

There are several strategies available to trailer owners to reduce their risk of theft, some as simple as a lock. All have some merit. The first position on the trailer that can be locked out is the coupler on the a-frame or trailer tongue. There are several versions of this type of lock available, but Fulton’s Universal Fit Coupler lock is very functional and cost-effective. Simply put, it is a heavy cast metal base with a ball to fill the coupler with a stainless bar over the lever lock to prevent access.
FULTON Universal Fit Trailer Coupler Lock #ULT1000600

If you want to reduce your risk when the trailer is coupled to the tow vehicle, try this:

If interested in keeping your wheels from turning to prevent theft, this would be helpful!
Lock’em Magnum Wheel Lock #RA25

And for a complete trailer security system, this is available with many accessories.
