Friction pads can become contaminated during use. This will reduce their stabilising efficiency. Dirty friction pads will look like this.
Gently rub the concave surface of the friction pads with a fine grade emery paper. This will remove residue from the surface and prolong friction pad life.
We recommend cleaning friction pads in this way before or after every journey to maximise their efficiency.
This is particularly important if you use a diesel towcar and can help relieve creaking/groaning whilst towing.
