Engine / equipment

Peugeot 308 with the 1.2-litre turbo petrol engine (built March 2013 to April 2017) and Citroën C4 II / DS4 (16 Jul 2014–8 Mar 2017)

Period mentioned

Recalls of November 2020 and June 2022

Symptoms

Less brake assist or none: the pedal goes hard and more force is needed.

Possible cause described

According to the official notices (Rappel Conso), the vacuum pump can be damaged by abrasion of the timing belt material (in the 2022 notice, by materials from the chemical corrosion of the belt with degraded oil), and then the brake assist can be reduced or lost, raising the risk of an accident. Peugeot 308 with the 1.2-litre turbo petrol engine: built March 2013 to April 2017. Citroën C4 II and DS4: 16 Jul 2014 to 8 Mar 2017. The notices give neither the repair nor the number of cars.

Check for the garage

Ask the brand by VIN whether it was done. If the brake pedal suddenly goes hard, press harder and go to a garage without driving on; also check in the service book when the timing belt was last changed.
