If your shoulder is 115mm from the tip of the axle you will need a weld ring with a square hole,
Suits 9 inch Hydraulic Backing Plates
Take extra care welding your weld rings into position. 1mm out of position and your brakes will overheat.
Here is a tip, dry fit your brakes as follows before welding:
- Insert bearings into hub dry.
- Ensure your brake shoes are concentric around the backing plate.
- Bolt your hydraulic backing plate onto the 9 inch Hydraulic Weld Ring
- Insert the hydraulic backing plate loosely into position on the axle.
- Insert your drum onto the axle and tighten the axle nut.
- Push your hydraulic backing plate into the drum until you cannot see the face of the shoe surface.
- Lock the shoes onto the drum with the adjuster.
- Tack the 9 inch Hydraulic Weld Ring and the backing plate into position.
- Loosen of backing plate adjuster until you can spin the drum.
- If you are happy everything is spinning freely, remove the drum and finish welding the weld ring.
- Grease up the drum and reassemble when cool.
- Tip: If your drum is grabbing, tap the brake adjuster with a hammer without going overboard. This will shock your shoes into position.
