Used Peugeot 108 Brake Servo

No — the Peugeot 108 does not have a traditional vacuum brake servo. The 108 uses an electrically-assisted braking system rather than a conventional servo unit, because its small three-cylinder engines (1.0 and 1.2 petrol, plus the VTi variants) do not generate reliable vacuum, and the electric motor variants have no engine vacuum at all. If your brake pedal feels heavy or unassisted, the fault is more likely in the brake master cylinder, the electric brake booster module, or the ABS/ESP unit — these are the parts worth searching for on Findapart instead.

It's quite likely there's a terminology mix-up, as the 108 was never fitted with a conventional vacuum brake servo at any point in its production run. What the breaker may actually have — and what you may genuinely need — is the brake master cylinder, the brake pedal assembly, or a brake pressure sensor or modulator associated with the ABS system. Give the breaker your registration number and ask them to confirm exactly which component they're listing, so you're both talking about the same part.

Because the 108 has no vacuum servo, a hard pedal on this car points elsewhere: the most common causes are a failing brake master cylinder, a fault in the electric brake assistance system, or an issue with the ABS/ESP modulator. A diagnostic scan will usually flag faults in the electric braking assistance before things get dangerous, so that's a sensible first step. Search Findapart for the master cylinder or ABS modulator for your 108, and include your registration when contacting breakers so they can match the correct unit.

For the parts that do exist on the 108 — master cylinder, ABS modulator, calipers — the trim level (Active, Allure, Roland Garros, or any special edition) does not affect which brake components are fitted; trim on the 108 relates to interior and cosmetic specification rather than the braking hardware. Engine size can matter for some brake components such as calipers and discs, since the 1.2 VTi is a slightly more powerful unit than the 1.0, so always quote your exact engine when contacting a breaker. Never assume parts interchange purely on trim name alone.

The Peugeot 108 was produced from 2014 (not 2012 — it replaced the 107 that year) through to 2021 with a facelift introduced around 2018, and the car shares its platform throughout with the Toyota Aygo and Citroën C1 of the same generations. For brake components such as calipers, master cylinders, and discs, whether parts from a pre-facelift 108 cross over to a post-2018 facelift car is something you should confirm with the breaker against your specific registration, as subtle changes can occur across a facelift boundary. Always give the breaker your reg so they can verify the part number rather than relying on year alone.
