Land Rover Discovery 1 3.5 / 3.9 / 4.0 V8: brake & clutch fluid change

Brakes · Discovery 1 (1989–98) · 1989–1998

How often: every 2 yrs. Brake fluid absorbs water. Wet fluid boils under hard braking and rusts the cylinders from inside.

Brakes	DOT4, minimum boiling point 260 °C
Clutch hydraulics	DOT4

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

Brake fluid (DOT4, minimum boiling point 260 °C; ≈1 L)
Clutch fluid (DOT4)

Tools

Bleed tube & bottle
Brake bleed spanner
Helper

Step by step

Bleed the brakes in the order your manual gives (ABS models have a specific order).
Keep the reservoir topped up so no air gets in.
Bleed the clutch slave cylinder.
Check the pedal is firm before driving.
