All of the Jaguar XK120 cars used a drum brake system on the front and rear. Two versions were used featuring either a single circuit or dual circuit hydraulic system. drum brakes are notoriously poor and require regular manual adjustment to maintain their performance.
In response, Fosseway Performance has developed a number of Jaguar XK120 brake upgrade kits to allow you to enhance your Jaguar XK120 brakes by fitting a disc brake conversion which, like all our products, can be installed without permanent modification to the car. The kits included our four piston caliper and these are carefully sized to ensure they remain compatible with the existing brake master cylinder and servo assembly. All kits are supplied with braided stainless steel brake lines.
When installing the disc brake conversionto a single circuit car we recommend upgrading your master cylinder and brake hydraulics to a twin circuit system.
