The fault

How you spot it

The piston of a rear caliper with an electric parking brake cannot be wound back by hand: the caliper has to be put into service mode with a diagnostic tool. Where that was bypassed, the actuator of the caliper is damaged, and soon after a disc replacement the caliper needs replacing too.

The other complaint that recurs on owner forums is the parking brake fault itself: an "electric parking brake faulty" message, sometimes together with faults in the related controllers (hill hold, hill start assist, stop-start). In that case it is not necessarily the brake that failed, but the sensor or the communication between the controllers.

How we know

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
