Dampers – If you can push the damper in without resistance or it springs back out the damper will need to be replaced. We recommend that a grease gun and cartridge are purchased when replacing to regrease the grease nipples and ensure the shaft glides smoothly.
Brakes – Measure across the drum, and then across the face of the shoe

• e.g. Al-Ko 2051 axle = 200m drum diameter, 51mm brake shoe width
