Volvo Amazon Brakes front

On the 122, the engine and chassis number determine which front brake the car has: early B16 cars run four-wheel drum brakes with a single-circuit master cylinder, while front disc brakes became increasingly common and were later combined with dual-circuit systems. This decides whether you're looking for drum parts and wheel cylinders or brake calipers, brake discs and splash guards – parts that aren't interchangeable between the versions.
