Peugeot 308 Brake Master Cylinder Replacement Parts

Yes, all variants of the Peugeot 308 have a brake master cylinder — it is a fundamental hydraulic component present on every car with a conventional brake system, regardless of engine, trim, or body style. The 308 has never been sold as an electric vehicle in the UK, so every version relies on a hydraulic braking circuit with a master cylinder. You will find one on petrols, diesels, and the plug-in hybrid (PHEV) variants alike, though the PHEV setup is more complex and worth discussing with the breaker.

The Peugeot 308 ran as a first generation (Mk1) from 2007 to 2013, and the second generation (Mk2) launched in 2013 and ran through to around 2021 — these are entirely different platforms with different brake system architectures, so the master cylinder from a Mk1 will not fit a Mk2. Always buy from the same generation as your car. Confirm the exact part with the breaker using your registration to be safe.

Engine size can influence the brake master cylinder specification on the 308, as larger or higher-output engines are sometimes paired with uprated braking components to handle greater stopping demands. If you are replacing the master cylinder on a higher-powered variant — such as a 1.6 THP petrol or a GTi — it is worth telling the breaker your exact engine code alongside your registration, rather than just the engine size in litres. This helps ensure the bore size and pressure rating of the used part matches your original unit.

Trim level alone does not affect the brake master cylinder specification on the Peugeot 308 — trims like Access, Active, Allure, and GT Line are distinguished by comfort and cosmetic features rather than changes to the braking hydraulics. What matters more is your generation (Mk1 or Mk2) and your engine. Give the breaker your registration and engine details rather than your trim name, and they can match the correct part.

2013 is the changeover year between the Mk1 (2007–2013) and Mk2 (2013–2021) 308, so cars registered in 2013 could belong to either generation depending on the exact build date. A Mk1-sourced master cylinder will not interchange with a Mk2, so you must confirm which generation your car actually is before buying. The safest approach is to give the breaker your full registration number so they can identify the correct generation from the vehicle record.

The body style — hatchback or SW estate — does not in itself dictate a different brake master cylinder, as the hydraulic system specification is driven by the platform, engine, and braking system rather than whether the car has a boot or a tailgate. A same-generation, same-engine SW and hatchback will typically use the same master cylinder. Confirm this with the breaker using both registrations to be certain, as there can always be production variation.
