How to Select Electric Brakes & Brake Parts

How to Select Electric Brakes & Brake Parts for a trailer, RV, utility trailer, cargo trailer, or travel trailer.

A few things to keep in mind...

  1. To determine the right or left side brake assembly, position the brake with the magnet at the bottom.  On electric brakes, the actuating arm will always curve from the pivot pin to the magnet, toward the left for left hand brakes and toward the right for right hand brakes.
  2. When ordering your brake assembly or brake replacement part, always use both the part number and the reference 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.  By removing 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 need new brakes to build a trailer-WE HAVE WHAT YOU NEED to do the job!  Some brakes can even be used for Travel Trailers and RV supplies.

Selecting electric brake parts:

  1. Determine the size of your brake...A. measure the diameter of the mounted brake shoe.  B.  measure the width of the lining.
  2. Determine the manufacturer of your brake..A. select the brake you have by looking at key identification points.  B. check the electric brake chart for your brake and the part you need.  Further identification may be made by referring to the exploded drawings and magnet photos of each brake.
  3. Select the part you need.  Though many parts are listed, we carry only the replacement parts numbered.  The words "parts only" indicate that complete brake assemblies are not available.

Reasons why brake hardware should be replaced:

  1. Worn, weak return springs will cause the brake linings to drag against the drum and cause premature brake failure.
  2. Hold-down springs will lose their tension and allow the brake shoes to wobble or ride up against the face of the brake drum, causing premature lining failure.
  3. A frozen adjusting screw will not allow shoes to be adjusted properly.
  4. Rubber dust plugs will crack with age and allow dirt to contaminate linings.
  5. A stretched self-adjusting cable prevents the self-adjusting lever from properly aligning the shoes.
