Used Vauxhall Cavalier Brake Discs

The Cavalier ran as the Mk2 (1981–1988) and Mk3 (1988–1995), and these are different platforms with different suspension and braking setups, so discs from one generation will not simply swap into the other. Name the generation and engine size when asking your breaker, as that is the key starting point. Never assume a disc from across that 1988 boundary will fit without the breaker checking against your registration.

The Mk3 ran from 1988 to 1995 and there were running changes during that period, including possible mid-generation brake specification updates that are difficult to confirm without checking. Because mid-generation brake upgrades are a known uncertainty, you should tell the breaker your exact registration and let them verify the spec rather than assuming all Mk3 discs are interchangeable. Engine size also matters, as larger-engined Cavaliers often carried uprated brakes.

Yes, engine size is one of the main factors — a 2.0-litre Cavalier, for example, was often fitted with larger or uprated discs compared to a 1.4 or 1.6 unit. When contacting a breaker, always quote your engine size alongside the generation, as supplying the wrong spec disc from a different engine variant is a common pitfall with used parts. Your registration is the safest way to confirm the exact brake specification your car left the factory with.

Trim level alone — whether your Cavalier is an L, GL, GLS, CDi or similar — does not determine the brake disc specification; what matters is the generation and engine size. That said, higher trim levels were sometimes paired with larger engines, so if your trim came with a bigger engine that is the relevant detail to pass on to the breaker. Expect minor cosmetic differences between used discs from different donor cars, but the mechanical fitment is driven by engine and platform, not badge.

Front brake discs were fitted across Cavalier variants, but rear brake arrangements varied — many Cavaliers used rear drums rather than rear discs, particularly on lower-powered versions. If you are looking for rear discs specifically, confirm with the breaker whether your particular engine and generation combination was actually fitted with rear discs at the factory. Quoting your registration is the most reliable way to avoid being sold a disc for an axle that ran drums on your car.

Both years fall within the Mk3 generation (1988–1995), so on the face of it the platform is the same, but mid-generation brake specification changes mean this cannot simply be assumed. Ask the breaker to cross-reference both registrations to confirm the disc diameter and hub arrangement match before purchasing. Engine size is consistent here at 1.8 which is a good sign, but let the breaker make the final call rather than relying on the shared year range alone.
