Peugeot 508 Brake Servo Replacement Parts

Most Peugeot 508s do have a conventional vacuum brake servo, but it is worth noting that some later 508s — particularly those with certain petrol and diesel engines where vacuum supply is limited — may use an electric or electrohydraulic brake booster rather than a traditional vacuum servo. If your car has an electric booster system, the unit you need is different from a conventional servo, so confirm with your breaker exactly which type your registration requires before ordering.

The Peugeot 508 first generation ran from 2011 to 2018, with a facelift arriving in 2014, so a 2012 and a 2016 car are both first-generation but sit either side of that facelift boundary. The brake servo may or may not interchange across the 2014 facelift — engine fitment and booster type can affect which unit is fitted — so always confirm compatibility against your specific registration with the breaker rather than assuming generation alone guarantees a match.

Trim level alone — whether Access, Allure, SR, or GT — does not determine which brake servo is fitted; what matters is the engine size and drivetrain, since larger or more powerful engines often use a different braking setup to carry the additional weight and power. Focus on matching the engine (for example 1.6, 2.0 TDI or 2.2 HDi) rather than the trim badge when sourcing a used servo. Your breaker will cross-reference your registration to confirm the correct unit.

The 508 was sold in saloon and SW (estate) body styles in the UK, and the brake servo is generally determined by the engine fitted rather than the body style. That said, if the SW variant carries a meaningfully higher kerb weight on a particular engine, there is a possibility the braking components differ, so it is worth confirming with your breaker by quoting both your registration and the donor vehicle's registration to be sure.

No — the second-generation 508, introduced in 2018, is a significantly different platform from the first generation (2011–2018), and the two generations do not share brake servo components. The second-generation car also introduced electrified powertrains, which may use an electric brake booster rather than a conventional vacuum servo, so make sure you and your breaker are clear on which generation and which booster type your car requires.

Give the breaker your full registration so they can verify the engine size and model year, as these are the key factors for servo fitment on the 508. Also ask whether the unit is a conventional vacuum servo or an electric booster, since the two are not interchangeable and later 508s may use either type. A reputable breaker should be able to confirm the donor vehicle's details so you can match them against your own car before committing.
