A spring tester has a hydraulic ram which urges a bearer plate towards a load cell to achieve a predetermined fixed spacing D between them. A replaceable spacer allows adjustment of the distance D to a distance d. A spring to be tested is compressed to the length d and the load indicated by the load cell. Under test, the spring is laid in a cylindrical channel in a carriage to simulate the operation of the spring in an aircraft braking system.
