Replacement guidelines
Replacing brake fluid is recommended every 48,000 km (30,000 miles), or every other year. In cars where the brakes are used and often (e.g. in hilly
areas or in tropical climates where humidity levels are high), fluid should be refaced each year.
Background
The reason that brake fluid should be changed is that brake fluid is hydroscopic: that is, it absorbs water molecules from the air. Water is partly
absorbed through the brake hoses and brake fluid reservoir, which are made of rubber and plastic respectively, and are to some extent permeable to
water molecules.
Increasing the water content of brake fluid means that the brake fluid's boiling point falls dramatically and that corrosion forms on the braking system
components. The result is that the braking system is damaged and its functioning seriously impaired.
Note: Use only Volvo original brake fluid marked DOT 4+. Never re-use brake fluid. Always keep brake fluid in its original packing, well sealed.
Note: Check continuously that there is enough brake fluid in the brake fluid reservoir when replacing brake fluid.
