Remove the brake line to the support arm of the three-way piece and eventually fill it with a M8 bolt.

Remove the cotter pin from the support arm and bearing nut. Unscrew the tap the nut with a blunt screwdriver without damaging the threads’ screw.
Remove the arm wiggling, pulling, moving or knocking.
Check the bearings. Red grease means there is rust in the bearing and it´s not good. Feel with your finger along the lower scale. Bumps are not good.
Tap the bearing shells from the support arm if you want to install new bearings. If you find a broken bearing you must also remove and discard the shell.
You can eventually put the new bearing and the shell in the same way as the ones that were there before. Remember to replace the inner support.
Move the support arm over the shaft and tap the outer bearing in the support arm.
Slide the outer support arm seal on the support arm and tighten the nut on the axle tube.
Tighten the nut to 50Nm and put the cotter pin on.
When connecting the brake lines follow these instructions:
Paste the nipple down with tape so that it cannot move
Slide the spiral axle tube and guide it so that it finally is connected with the nipple in the tree-way piece. Use a new line and put the rubber nipple down to 7-9 Nm
Secure the mounting bolt of the brake line fixed with 10Nm. Note whether the ridge is into the notch of the shaft tube and check if the brake line doesn´t come in contact with the axel tube.
Insert the rubber ring to the brake line to protect the shaft in the three-way piece.
Bring the plastic dust cover and secure it with a strip.
