9-inch Mechanical Brake Plate – Left Side
A 9-inch left-hand mechanical brake plate is activated at the brake lever, causing two identical shoes to apply braking force into a cast-iron brake drum.
Brake shoes and discs are known as friction brakes. Vehicle brakes are also friction brakes; however, these braking systems may be hydraulic or electric.
Installation of the Brake Shoes
However, please pay attention to the shoe offset below when installing it into a drum.
Locate the handbrake on the bottom of the axle.
13-inch to 14-inch wheels 1450kg. 15-inch to 16-inch wheels is 1200kg
Brake Shoes
9-inch x 45mm. Maximum cable tension during braking is 165kg. Hole spacings are 76.15mm P.C.D.
Replacing the backing plate is occasionally better, as other components may show wear. A four-hole post mount fixes mechanical braking plates welded to the axle behind the rear grease seal.
Removing a few bolts and replacing the whole backing plate, which is relatively inexpensive, makes the job more manageable.
How to replace 9 inch Brake Shoes
- 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.
- Assemble the new backing plate shoes with the springs between the brake shoes, as shown in the image above.
- The longer spring must be assembled in the lower position, and the shorter spring in the top position. Note that left-hand side brakes are a mirror image of right-hand side brakes.
Fit the drum over the brake shoes and reassemble.
Why do my trailer brakes fade?
- Dirt, oil or grease on the brake shoes – clean
- Worn brake shoes – replace
- Badly adjust brake shoes – adjust
- The trailer is overloaded, causing the brakes to overheat. Reduce trailer weight or upgrade trailer.
