Customers that leave servicing/maintenance too long regularly have the following problems.

Trailer brake cables

Brake cables seize and due to the lack of movement the expander seizes leaving the brakes in an open position. As a result the brake shoes rub the brake drumthat wears the shoes. Brake shoes rubbing on a drum may also result in damage to the drum. This canalso effects the brake efficiency and the amount of fuel used to tow. When you really need the brakes they do not work. This can cause an accident for the cost of a brake cable.

Wheel bearings

With wheel bearings you usually will get a bit of warning (play) before a bearing fails. When a wheel bearing fails the whole wheel usually comes off this can damage the shaft as it comes off or if the shaft hits the floor. This means a new axle / suspension unit at an high cost also a trailer wheel can cause a lot of damage/ injury if it hits something or a person.
