Second Hand Peugeot 407 Brake Master Cylinder

Yes, every Peugeot 407 has a brake master cylinder — it is a fundamental hydraulic component that converts pedal pressure into braking force and is fitted to all variants regardless of engine, trim or body style. The 407 was produced from 2004 to 2011 as a saloon, estate (SW) and coupé, and all of these use a conventional hydraulic braking system with a master cylinder. There are no drivetrain exclusions to be aware of here, unlike parts such as propshafts or intercoolers.

The 407 received a facelift around 2008, and while the underlying platform remained the same, hydraulic braking components can vary between pre-facelift and facelift builds — particularly if Peugeot revised brake specs at that point. You should confirm with the breaker that the part number on your existing unit matches the one being supplied, quoting your registration so they can verify against their records. Naming the generation boundary is important here: do not assume a pre-2008 unit will simply drop in to a post-2008 car without checking.

Engine size can influence brake master cylinder specification on the 407, because larger or more powerful engines are often paired with uprated braking systems that require a different bore size in the master cylinder. For example, a 2.7 HDi or 3.0 V6 petrol variant may carry a different unit than a 1.6 HDi. Always tell the breaker your exact engine size and registration so they can match the correct spec.

Trim level does not in itself determine which brake master cylinder your 407 needs — this part is governed by the generation and engine size, not whether the car is badged SE, S, or GT. That said, higher-performance trim variants may have been factory-fitted with larger brake systems, so the engine and build date still need to match rather than the trim name alone. Confirm with the breaker using your registration rather than relying on the trim badge.

The body style — saloon or SW estate — does not in itself change the brake master cylinder specification, as fitment is driven by engine size and generation rather than the body variant. A cylinder from a same-engine, same-era SW and saloon is likely to be the same part, but always ask the breaker to cross-reference part numbers against both registrations to be certain. Do not rely solely on body style as confirmation of compatibility.

A 2006 unit sits in the pre-facelift period and a 2010 unit is a post-facelift car, so there is a generation boundary between them that makes a straightforward swap uncertain. The platform is shared, but brake specifications can differ across that divide, and engine variants also changed over that period. Route this question to the breaker with both registrations and, if possible, the part numbers from each car to get a reliable answer before buying.
