NULON Xtreme Performance Brake Fluid - Super DOT 4 20L for CITROEN C2

Nulon Extreme Performance Brake Fluid (XBF) is a high-performance borate ester brake fluid (Super DOT 4) which optimises the benefits of superior boiling point and high vapour lock temperature throughout its service life.

Nulon Extreme Performance Brake Fluid is compatible with all metals and rubber seals typically used in automotive braking systems. It is intended for use both as initial fill and in aftercare markets. Nulon Extreme Performance Brake Fluid (XBF) is manufactured as a clear amber coloured fluid. It is suitable for all disc, drum, anti-skid ABS braking and electronic stability control systems used in standard to high performance vehicles with high thermal load around the braking system.

Product Application

Service Life

Nulon XBF should be changed every 24 months under standard driving conditions in order to maintain protection against vapour lock and corrosion.

Compatibility

Nulon XBF is only compatible with brake fluids that meet the DOT 4 or Super DOT 4 brake fluid specifications.

Useful Information

Nulon XBF contains inhibitors to reduce corrosion of the many alloys components found in braking systems. Oxidation inhibitors are also used to prevent the oxidation process of the fluid.

Nulon XBF has no adverse effect on the physical properties of the rubber cups and O rings used in the master and wheel cylinders.

Equilibrium reflux boiling point (ERBP) is the average temperature of a fluid boiling under equilibrium conditions (reflux) at atmospheric conditions. High performance brake fluids such as Nulon XBF must have a high enough boiling point (ERBP) to resist vapour lock under severe braking conditions. Note that the boiling point of the brake fluid will deteriorate significantly with moisture adsorption. With use, brake fluid absorbs water from the atmosphere and reduces the ERBP.

It is difficult to completely seal the braking system to prevent the ingress of atmospheric moisture or water splashes through hoses and the master cylinder. Brake fluids must withstand the absorption of at least 3% to 4% water without lowering the boiling point to a dangerous level. The presence of more free water significantly increases the chance of brake failure due to vapour lock and can promote corrosion of the brake system. This is why it is so critical to change the fluid every two years.
