9″ Brake Shoes – Mechanical
9-inch Mechanical Brake Shoes
9-inch mechanical brake shoes suit mechanical drum brakes and backing plates.
This brake shoe pair fits on the backing plate's left and right sides. One pair suits one drum. Suitable for all 9-inch mechanical drums except early model, including Wesco.
Take care when inserting these brake shoes.
Installed the wrong way, these shoes will create a lot of heat and bearing wear.
A worn bearing casting causes roller wear resulting in carbon black in your grease. If your witness black grease, replace your bearings immediately.
If you have replaced your bearing with Japanese bearings and still have hot brakes, look closely at your brake shoes.
When installing mechanical backing plates, ensure the parking brake lever is located at the bottom or in the 6 o'clock position. (Note: this is the reverse for electric brakes.)
Occasionally, replacing the whole backing plate is better as other components may show wear.
The job becomes easier by removing a few bolts and replacing the whole backing plate.
Furthermore, replacing the entire backing plates is relatively inexpensive and may fix problems not readily apparent.
How to replace a 9 inch Brake Shoe
- Take off the wheel, remove the grease cap and split pin and take off the drum.
- Remove the worn brake shoes.
- Keep the springs in a container ready for re-insertion.
- Check that grease is on the backing plate under the lever assembly (at the bottom). Use molybdenum grease as required.
- Insert the new shoes into the backing plate with the springs between the shoes.
- The longer spring must be assembled in the lower position, the shorter spring in the top. Note that left-hand side brakes are a mirror image of right-hand side brakes.
- Finally, fit the drum over the brake shoes and reassemble. The assembly order is shown below.
