Tyre part fileTyre:
Tyre part fileThe width of the tires/rim assembly is measured with the tire fitted on its rim at its rated pressure. Caution: The manufacturer’s size indications should not be taken as measure, as the width of the rim directly impacts the width of the rim/tire assembly.Tyre:
Tyre part fileBrakingThe vehicle must be equipped with a four-disc hydraulic brake system.DiscsHydraulic connectionsThe system must be equipped with a brake pedal.Minimum surface area of brake pedal: 25 cm2.Brake pedalBrake pedalThe brakes must operate independently on the front and rear axles or in an X pattern (i.e. right front wheel with left rear wheel, and left front wheel with right rear wheel).Front brakelineRear brakelineA single master cylinder may be used, provide that it has a dual circuit (two pistons and dual tank).Master cylinders:
Master cylinder part fileThe vehicle must remain immobile when it is placed on a 20 % incline with the main brake in place.Race Inspectors may check the brakes again just prior to start.Brake circuit:
Technical k-brief on brake circuitWet weather capability is mandatory (see Article 5.6)Brake circuit:
Technical k-brief on brake circuitWet weather running (mech)Must be able to race during conditions of light rain/drizzle.The vehicle must be adequately ventilated to prevent driver’s compartment from fogging.Windscreen wiper(s)The vehicles must be equipped with an effective electric windscreen wiper(s).(mech) The operation of the wiper assembly must be activated by an independent switch easily accessible to the driver.(mech) The wiper operation must provide the driver a clear view.The vehicle’s brake effectiveness may be re-inspected before and/or after any run.The vehicle’s electrical system must be suitable for wet weather conditions (e.g. will not malfunction during wet conditions).Requirements specified by teamBrake circuitBraking force 20%slope:
