1997 Daihatsu Terios Brake Fluid: What It Does and When to Change It

The 1997 Daihatsu Terios is fitted with a conventional hydraulic braking system (front disc, rear drum), so brake fluid absolutely is used and is relevant to servicing. Daihatsu’s factory literature for the J100-series Terios (1997–2005) specifies glycol-based brake fluid meeting SAE J1703/FMVS S No.116 standards (commonly DOT 3, with DOT 4 acceptable), and the system is vacuum-assisted. That aligns with standard automotive practice and regulatory specs for hydraulic brake fluids set out in FMVSS No.116.

On this Terios, brake fluid is the lifeblood of the braking system. When the driver presses the pedal, fluid pressure travels through the lines to the calipers and wheel cylinders, converting foot effort into reliable stopping power. It also protects internal components from corrosion and must resist boiling under hard use so the pedal stays firm on steep Kiwi roads or in hot Aussie summers.

As a hygroscopic fluid, it gradually absorbs moisture from the air. Over time that lowers its boiling point and can lead to a spongy pedal, fade on long descents, and internal corrosion. That’s why Daihatsu service guidance and industry best practice recommend replacing the Terios’s brake fluid roughly every 2 years or about 40,000 km, sooner if towing, off-roading, or driving in humid coastal conditions.

When servicing a 1997 Terios, a workshop will typically:

• Use DOT 3 or DOT 4 glycol-based fluid from a sealed container (never DOT 5 silicone).
• Inspect fluid colour and moisture content
