- Proper Parking: They help the wipers park in the correct position when turned off, preventing damage and improving visibility.
Tips: Refer to your vehicle’s manual to understand the specific role and location of the wiper brakes.
2. Gather the Necessary Tools and Materials
Why It Matters: Having the right tools and materials ensures that the installation process is efficient and effective.
Tools Needed:
- Socket set or wrench set
- Screwdrivers (flathead and Phillips)
- Replacement wiper brakes
- Lubricant or grease (optional)
- Safety gloves and goggles
Tips: Check your vehicle’s manual for any specific tools or parts required for your make and model.
3. Prepare the Vehicle
Why It Matters: Proper preparation ensures safety and provides easy access to the wiper mechanism.
How To:
- Turn Off the Ignition: Ensure the vehicle is turned off to avoid accidental activation of the wipers.
