Check of brushes of screen wipers is necessary for carrying out in a following order. Check the BMW X5 E53 wiper mechanism, tighten its fasteners. Check brush rubber for hardening or cracking.
- Wet the windshield and turn on the wipers. Let them run for a while and turn them off. Check the glass surface - uneven brush marks or streaks on clean glass indicate that the brushes need to be replaced.
If there is a need to replace only the rubber blade of the brush, then use pliers to remove the end of the blade from the frame and remove the completely old blade. Install the new canvas in the frame and clamp it with pliers. After replacing the brush, check its operation on the windshield.
