Brake Fluid: Procedures
Checking Brake Fluid Level
Brake System:
The brake fluid level should be between the MIN and MAX marks.
Fluid type: DOT 4+
Replace: Every second year or 30,000 miles (48,000 km). The fluid should be replaced once a year or every 15,000 miles (24,000 km) when driving
under extremely hard conditions (mountain driving, etc.)
Check, without removing the cap, that the level is above the "MIN" mark of the fluid reservoir.
Always entrust brake/clutch fluid changing to an authorized Volvo retailer.
Changing Brake Fluid
Changing Brake Fluid, General
When to change?
It is advisable to change the brake fluid every 45,000 km (28,000 miles) or every two years. If the brakes are used frequently and heavily, such as in
mountainous areas or in a tropical climate with a high degree of humidity, the brake fluid must be changed every year.
Why change?
Brake fluid is hygroscopic, in other words it extracts water from the air. This happens, among other things, via the brake hoses and the brake fluid
reservoir, which are made of rubber and plastic respectively and not completely resistant to water molecules.
A high water content greatly lowers the boiling point of the brake fluid and causes corrosion in the brake system.
This damages the brake system and braking operation is reduced.
NOTE: Use only original Volvo brake fluid with the (minimal) code DOT 4+. Never re-use brake fluid. Always store brake fluid in its original
packaging, carefully closed.
Preparations
Use of a bleed system is recommended.
Take a collecting bottle with a transparent hose to collect the brake fluid.
Connecting bleed unit
Connect the bleed unit to the brake fluid reservoir. Follow the manufacturers' instructions for connecting and using the unit.
