Brake system: visual inspection of the brake pads and brake discs for wear
| WARNING | Risk of accident if brake pads and/or brake discs are not replaced in time. Injury and material damage due to impaired braking effect. |
> The brake pads must be replaced when the brake pad warning indicator lights up, but no later than when there is a residual pad thickness of 2 mm.
> Brake discs must be replaced on reaching the wear limits.
Note. If brake pad wear is indicated by the warning light, the warning contact (sender including wire and plug connection) must also be replaced. Replacing the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm. Warning contacts must be replaced if the core of the line is worn. However, if only the plastic part of the warning contact is worn, there is no need to replace it.
