This brake hose is suitable for installation in the braking system of a Renault R4. The hose has a length of 510 mm and forms the flexible connection between rigid brake lines and wheel cylinders or calipers. The material resists brake fluid and pressure within the hydraulic system. The fittings at both ends match the original connections of the vehicle. The brake hose supports stable brake pressure distribution between master cylinder and wheel brakes. Application is focused on safe operation of the braking system during maintenance or replacement of worn hoses.
