Used Mercedes-Benz SLK Brake Discs

The SLK R171 generation ran from 2004 to 2011, so both years sit within the same body shell, but brake disc sizing on the R171 varied depending on engine — the 200K, 280, 350 and 55 AMG did not all share the same disc dimensions. Match the engine size as well as the generation, and confirm the exact part against your registration with the breaker before buying.

The R170 ran from 1996 to 2004 and the R171 from 2004 to 2011 — these are distinct generations with different running gear, and the brake discs are not the same. You need to source discs specific to your generation, so tell the breaker your exact year and engine when you request a quote.

Yes, it matters on the SLK — larger and more powerful engines such as the 350 and 55 AMG typically carried bigger, uprated brake discs compared with the four-cylinder and smaller V6 variants. Always quote your engine size alongside the year and generation so the breaker can match the correct disc diameter and thickness.

Trim level on its own does not affect brake disc fitment — what drives the difference is the engine size and the generation, not whether the car is a standard or higher-spec trim. Focus on getting your engine code, year and generation right, and the trim name alone won't change what the breaker needs to find the correct discs.

Yes, always specify front or rear when requesting brake discs, as the dimensions differ between axles on the SLK. The SLK is a rear-wheel-drive two-seater roadster, so both axles carry discs, and quoting the wrong axle could mean you receive a part that won't fit.

No — all Mercedes-Benz SLK variants across the R170, R171 and R172 generations were fitted with disc brakes on both axles as standard, so this is a genuine like-for-like used part search regardless of which SLK you own. Just make sure to match generation and engine size, and confirm the full specification with the breaker against your registration number before committing to a purchase.
