Replacing mounting kits for brake systems
When replacing break pads, it is tempting to re-use old mounting kits to save time and money. The enormous temperature fluctuations around wheel brakes in particular ensure a considerable decline in spring rates over time, especially in spring components.
We therefore recommend that you also replace the springs with every brake change, as reusing the old retainer springs or sliding plates can cause problems if the break pads are not held securely in the caliper. If the coverings come loose, they may move during operation, leading to unwanted noise (rattling).
If the covering sits insecurely, this can lead to uneven wear and subsequent reduction of the brake effect (performance).
Replacing the springs also saves having to clean the old springs.
Within one to two years, the spring force reduces by at least 50%.
These principles also apply to springs when replacing break shoes. Reuse of the old springs can also cause problems here, as the force load is considerably reduced.
The risk of noise developing (rattling) increases if the break shoe is sitting insecurely. This can also cause uneven wear and consequently a reduced brake effect (performance) or grinding on the drum. The result is excessive heat generation.
Within one to two years, the spring force reduces by at least 30%.
When checking or replacing the brake shoes, it is recommended to examine the handbrake adjuster for wear. Wear on this part can result in incorrect behaviour of the handbrake shoe.
