Frequently Asked Questions
The overrun device is the component between the coupling and the drawbar. Typical signs of wear:
- Defective shock absorber on the overrun device: The trailer sways noticeably when braking and setting off; the combination feels unstable. A leaking or oil-soaked shock absorber clearly needs replacing.
- Drawbar stiff or worn out: If it can only be pushed in with a jerk or has noticeable play up and down, the bearing sleeves or drawbar are worn. Replacement: Bearing sleeves and drawbars.
- Torn bellows: Water and dirt penetrate through the tear — and this is precisely what subsequently ruins the bushings and drawbar. A torn bellows is a minor issue, but the resulting damage can be costly. Therefore, check the following during your annual inspection: bellows.
- Handbrake lever: If it is too easy to pull, no longer holds, or the spring has lost its tension, the trailer will no longer be reliably secured when stationary. Replacement: handbrake lever.
Rule out the simple causes first: before replacing the entire overrun braking system, check the brake cables, linkage and adjustment. Weak braking performance is far more often caused by stiff cables than by the overrun braking system itself.
Repair or replace completely? Replacing individual parts is worthwhile as long as the drawbar itself is in good condition. If it is warped, heavily rusted or worn out, replacing the entire overrun braking system is the better option — when you add up the cost of the individual parts, the total is often in the same ballpark anyway.
