3. Varnostne informacije

Before beginning any work on your vehicle's braking system, it is crucial to observe proper safety precautions. Brake system work can be complex and should ideally be performed by a qualified technician. If you choose to proceed yourself, ensure you have the necessary tools and knowledge.

• Vedno nosite ustrezno osebno zaščitno opremo, vključno z zaščitnimi očali in rokavicami.
• Preden začnete delati pod vozilom, se prepričajte, da je ono varno podprto z dvigalkami na ravni površini. Nikoli se ne zanašajte samo na dvigalko.
• Disconnect the vehicle's battery to prevent accidental electrical shorts or activation of vehicle systems.
• Preden začnete z delom, pustite, da se zavorne komponente ohladijo, saj se lahko med delovanjem zelo segrejejo.
• Za podrobna navodila in specifikacije navora glejte servisni priročnik vašega vozila.
• Otroci in hišni ljubljenčki naj ne bodo v bližini delovnega območja.

4. Nastavitev in namestitev

This section outlines the general procedure for replacing the front disc brake pad wear sensor. Specific steps may vary slightly depending on your vehicle model. Always consult your vehicle's service manual for precise instructions.

4.1 Kontrolni seznam pred namestitvijo

• New Dorman BW1011 Brake Wear Sensor.
• Appropriate jack and jack stands.
• Wheel lug wrench.
• Basic hand tools (e.g., screwdrivers, pliers, wire cutters).
• Čiste krpe ali delovne brisače.
• Vehicle service manual (recommended).

4.2 koraki namestitve

1. Pripravite vozilo: Park the vehicle on a level surface, engage the parking brake, and block the rear wheels. Loosen the lug nuts on the wheel where the sensor is to be replaced. Using a jack, lift the vehicle and secure it with jack stands. Remove the wheel.
2. Poiščite stari senzor: The brake wear sensor is typically attached to one of the front brake pads and routed along the brake line or suspension components. Identify the existing sensor and its routing.
3. Disconnect the Old Sensor: Carefully disconnect the electrical connector of the old sensor. This usually involves pressing a tab or releasing a clip.
4. Remove the Old Sensor: Detach the sensor from the brake pad and unclip it from any mounting points along its route. Dispose of the old sensor responsibly.
5. Namestitev novega senzorja: Carefully attach the wear tip of the new Dorman BW1011 sensor to the designated slot on the new brake pad (if replacing pads simultaneously) or the existing pad. Ensure it is securely seated. Route the new sensor cable exactly as the old one was routed, securing it with any clips or ties to prevent it from interfering with moving parts.

7. Ponovno sestavite: Reinstall the wheel, hand-tighten the lug nuts, then lower the vehicle. Torque the lug nuts to the manufacturer's specifications.
8. Testni sistem: Start the vehicle and check for any brake warning lights. If the light persists, refer to the Troubleshooting section or consult a professional.

5. Načela delovanja

The Dorman BW1011 brake pad wear sensor operates on a simple electrical principle. It contains a conductive loop embedded within a plastic housing. As the brake pad wears down, the rotor eventually makes contact with the sensor's wear tip, breaking the electrical circuit. This interruption in the circuit signals the vehicle's onboard computer, which then illuminates a brake wear warning light on the dashboard, indicating that the brake pads have reached their minimum safe thickness and require replacement.

6. Vzdrževanje

The Dorman BW1011 brake pad wear sensor is designed to be a maintenance-free component. However, it is crucial to inspect the sensor and its wiring during routine brake service or whenever brake pads are replaced. Look for:

• Fizična poškodba: Check for cuts, abrasions, or cracks in the sensor wire or housing.
• Pravilno usmerjanje: Ensure the sensor wire is securely clipped and not rubbing against any moving parts or hot surfaces.
• Varna povezava: Verify that the electrical connector is clean, dry, and firmly seated.

If any damage is observed, the sensor should be replaced to ensure accurate brake wear indication.

7. Odpravljanje težav

If you encounter issues after installing the Dorman BW1011 brake wear sensor, consider the following troubleshooting steps:

• Brake Warning Light Remains On:
  • Verify that the new sensor is correctly installed and fully seated in the brake pad.
  • Check the electrical connection for tightness and ensure no pins are bent or corroded.
  • Inspect the entire length of the sensor wire for any damage or pinching.
  • Ensure the brake pads themselves are not excessively worn, as the sensor will trigger if they are.
  • Some vehicles may require the brake wear light to be reset using a diagnostic tool after sensor replacement. Consult your vehicle's service manual or a qualified technician.
• Brake Warning Light Does Not Come On (and pads are worn):
  • This indicates a potential fault with the sensor or its wiring. Re-inspect the sensor for proper installation and any damage.
  • Ensure the sensor's wear tip is making proper contact with the rotor when the pads are worn.
  • A diagnostic scan may be necessary to identify electrical faults in the circuit.
