Mercedes-Benz GLB Brake Pedal Replacement Parts

Yes, all variants of the Mercedes-Benz GLB have a conventional brake pedal – it is a standard component regardless of engine, drivetrain, or trim level. The GLB is available with both petrol and diesel engines as well as a plug-in hybrid (GLB 250e), and all of these use a conventional pedal-operated braking system, so you are looking for the right part. The only scenario where the pedal mechanism can differ slightly is on the plug-in hybrid variant, which has a brake-by-wire element, so if your GLB is a 250e it is worth confirming the exact pedal assembly with the breaker against your registration.

The Mercedes-Benz GLB (X247) launched in the UK in late 2019 and received a mid-life facelift in 2023, so there is effectively one generation but two phases: pre-facelift (2019–2022) and facelift (2023 onwards). The brake pedal box and mounting assembly are part of the bulkhead structure, and while the fundamental layout is unlikely to have changed dramatically between phases, you should confirm with the breaker whether the pedal from a pre-facelift car is a direct swap into a post-facelift car, particularly if your car is a 2023 or newer model. Always quote your registration to the breaker so they can verify the exact part number.

Your 2020 GLB is a pre-facelift X247 and your 2023 car is a post-facelift X247 – they share the same generation platform, which makes a swap plausible, but the 2023 facelift is precisely the kind of mid-generation boundary where Mercedes-Benz occasionally revised interior and pedal-box components. We would not confirm this interchange as guaranteed; take both registrations to the breaker and ask them to cross-reference part numbers before committing to the purchase.

For the brake pedal itself – the mechanical pedal arm and pivot assembly – engine size and power output do not typically change the part, as the pedal interfaces with the brake booster or brake-by-wire system rather than being sized to the engine. However, the GLB 35 AMG has AMG-specific braking hardware further down the system, and it is worth confirming with the breaker that the pedal assembly from a standard GLB is compatible with the AMG variant if that is your car. Always give the breaker your exact registration to rule out any AMG or hybrid-specific differences.

Trim level – whether SE, Sport, AMG Line, or AMG Line Premium – does not affect the fitment of the brake pedal on the GLB, as trim differences relate to cosmetic and equipment choices rather than the pedal-box structure. You may find that the pedal itself looks slightly different (for example, a rubber pad versus a stainless-steel sport-style cover) depending on the trim the donor car came from, but the underlying mechanical assembly should interchange. If cosmetic appearance of the pedal face matters to you, mention the trim of your car to the breaker so they can try to match it.

UK breakers on a marketplace like Findapart will need your vehicle registration number as the primary reference, since this allows them to confirm the exact X247 build specification including engine, drivetrain (4MATIC or front-wheel drive), and whether your car is a hybrid variant. It is also helpful to tell them the model year and trim level, and to mention if your car is a pre-2023 or post-2023 facelift model. Giving them the Mercedes-Benz part number from your existing pedal, if accessible, is the most reliable way to ensure you receive the correct assembly.
