Regenerative braking heats the discs less often, but brake fluid it still absorbs water from the air. In a hybrid this fluid also feeds the actuator. Wet DOT lowers the boiling point and corrodes the pump and the calipers.
When to replace
- By the cap: usually DOT3 or DOT4, roughly every two years
- When the fluid is dark or the pedal travel grows after harder braking
- At every actuator replacement and when the system has air in it
How we do it
Topping up to the mark does not pull water out of the lines. We replace the fluid by bleeding, in a hybrid often with a scanner so the actuator pump flushes the circuit. Pads are a separate check: pads and discs.
Fluid dark or the pedal travel growing? We will replace it and bleed the system.
