Description
Electronic parking brake mechanism for Citroën C4 Picasso and Grand. Tested working. Up to 2013.
This electronic parking brake (EPB) mechanism is a direct-fit solution for Citroën C4 Picasso models (including Grand variants) produced up to 2013. Designed for professional workshops and experienced DIYers, the unit restores reliable parking brake function, eliminates irregular handbrake operation and parking brake warning lights, and is compatible with common Stellantis part numbering for Citroën/Peugeot vehicles. Use the listed product codes when searching or ordering to ensure quick match and accurate fitment.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C4 Picasso, Citroën C4 Grand Picasso (up to 2013)
- Product Codes: 0204280099, 9684898480, 470207
- Other Numbers: 470220
Function
The electronic parking brake replaces the conventional handbrake cable and lever with an electric actuator and control mechanism. On activation, the EPB applies the rear brakes automatically and holds the vehicle in position. It also integrates with the vehicle’s brake and stability systems to provide safe parking on slopes and during hill starts when combined with the vehicle’s control units.
Fitment & Replacement
Typical replacement workflow (for trained technicians and experienced DIYers):
- Prepare the vehicle on a level surface and secure wheels. Use suitable lifting equipment and supports.
- Disconnect the negative terminal of the battery before starting work.
- Raise the vehicle and remove the rear wheels to access the EPB assembly (location depends on variant: caliper-integrated actuator or central actuator unit).
- Disconnect the electrical connector and any retaining clips, then unbolt and remove the faulty unit.
- Install the replacement unit, reconnect wiring and connectors, and torque fasteners to manufacturer specifications.
- Perform EPB initialization/calibration with an appropriate diagnostic tool to ensure correct travel and integration with vehicle systems.
- Lower the vehicle, verify warning lights are cleared, cycle the EPB several times and perform a short test drive to confirm correct operation.
Installation Recommendations
- Always disconnect the battery before disassembly to avoid electrical damage or unintended actuation.
- Use a manufacturer-level diagnostic tool (e.g., DiagBox or an equivalent) to initialize/calibrate the EPB after replacement; without initialization the system may show faults or not operate correctly.
- Inspect electrical connectors and wiring for corrosion or damage; replace any degraded clips, seals or boots to prevent future ingress.
- Follow manufacturer torque settings for all fasteners and observe safety procedures when working under the vehicle.
Most Common Failure Reasons
- Mechanical wear or seizure of the actuator motor due to contamination or corrosion.
- Water ingress or rusting of mechanical components, causing binding or loss of movement.
- Electrical faults: damaged connectors, wiring harness issues or actuator motor electrical failure.
- Normal wear of brake components and related hardware that affects EPB operation.
Use the provided product codes when searching for compatible replacements to speed up identification and ordering. Ideal for workshops and skilled home mechanics who require a reliable, code-matching EPB solution for Citroën C4 Picasso models up to 2013.
