Mercedes-Benz CLS Brake Servo Replacement Parts

Yes, the CLS is fitted with a vacuum brake servo as standard across its generations, helping to boost pedal effort for the braking system. This applies to both the W219 (2004–2010) and W218 (2011–2018) generations. The servo is a genuine, serviceable component and used units are commonly sourced from breakers.

These are two distinct generations — the W219 ran from 2004 to 2010 and the W218 from 2011 to 2018 — and the brake servo is unlikely to be a direct swap between them due to differences in bulkhead design and braking system layout. You should treat these as separate parts and source a servo from the correct generation. Confirm compatibility against your registration with the breaker before purchasing.

Engine size can influence the braking specification on the CLS, as higher-powered variants such as the CLS 500 or CLS 63 AMG may carry a different servo setup to match their larger brake assemblies compared to a CLS 250 or CLS 350. When asking a breaker for a quote, always give your engine size or AMG designation alongside your registration. This helps ensure you get a servo matched to the correct braking system rather than a lighter-duty equivalent.

Trim level in the cosmetic sense — such as interior specification or equipment packs — does not affect brake servo fitment, so you can ignore those differences. However, the AMG variants like the CLS 63 AMG are likely to carry a higher-specification servo to suit their uprated braking systems, making them functionally distinct from standard trim servos. Always tell the breaker your exact engine and variant, not just the model name.

The W218 CLS received a facelift in 2014, bringing styling and equipment updates, but whether the brake servo itself changed at that point is not something we can state as fact. The generation boundaries are clear — W218 ran 2011 to 2018 with the facelift at 2014 — but whether a pre-facelift servo crosses over to a post-facelift car is something you must confirm with the breaker against your specific registration. Do not assume the parts are interchangeable across that boundary without checking.

The CLS Shooting Brake is a genuine body style offered within the W218 generation (2012–2018) alongside the four-door coupé. The brake servo is part of the running gear rather than the bodywork, so it may well interchange between the two body styles within the same generation, particularly if the engine size matches. That said, confirm this directly with the breaker against both registrations before buying, as minor differences can exist.
