Parking brake fault on Grand C4 Picasso MK2

Post by bryanheo »

Hello

Car Model: Citroen Grand C4 Picasso 1.6 BlueHDi Flair EAT6 (Registered in 2017)

When I drive my car, a dashboard panel shows 3 warning lights as shown below and the car does not move at all even though the parking brake is released

According to the Handbook, it seems that the issue is serious.
Has anyone got the experience? If yes, could you let me know what the problem is and how to resolve it?

Welcome along!

It's likely that one (or more) of the wires to one (or both!) of the handbrake motors has rubbed / rotted through on the inside of the ducting. As these are electric if it has failed in the 'on' position, then the only way to get it off (unless you fix the wire!) will be to remove the motor from the back of the caliper, and then wind the caliper back manually.

Thank you Richard,
As you suggested, I will check the wire and caliper.
