- Protects the overrun brake's sliding rail from dust, dirt, and moisture
A bellows for an overrun brake protects the overrun brake's sliding rod from dust, dirt, and moisture. When braking, the sliding rod slides in as the trailer or caravan pushes. This activates the brakes. The sliding rod is made of steel and lubricated to slide as smoothly as possible. The bellows prevents dirt and dust from getting on the grease, thus allowing the sliding rod to do its best work. Since the bellows is exposed to all weather conditions, it should be replaced in good time to keep the overrun brake well protected.
Replacing the bellows:
Important when replacing is the type and/or brand of the overrun brake (found on the type plate of the overrun brake), this determines the size of the bellows.
Measuring the diameter of the coupling side and the diameter of the overrun brake side yourself is also an option. Note recesses for, for example, the mounting bolts of the ball coupling.
Use wrench 19, disassemble the bolts/nuts on the coupling and remove the bellows. Install the new bellows. This can be tied down with a tie-wrap.
Replace the coupling and install bolts/nuts with wrench or ratchet 19.
