1999 Daihatsu Gran Move Brake Hose — What it does and when to replace

Yes, the 1999 Daihatsu Gran Move (also known as the Pyzar, G30 series) uses flexible brake hoses. This is confirmed in Daihatsu’s workshop literature for the G303/G313 platform and the Daihatsu Electronic Parts Catalogue, which show front caliper hoses and a rear axle flex hose feeding the rear wheel cylinders. Independent data services (e.g., Autodata brake system diagrams for late‑90s Daihatsu small MPVs) depict the same hydraulic layout. So the brake hose is absolutely relevant to this model.

The brake hose’s job is simple but vital: it carries brake fluid pressure from the rigid chassis lines to the moving bits at each wheel. Because the front wheels steer and the suspension moves through its travel, a flexible hose is needed so the line doesn’t crack. On the Gran Move’s front disc and rear drum setup, good hoses keep pedal feel firm and braking straight and predictable.

As part of routine servicing, the brake hoses deserve a close look every 10,000–15,000 kilometres or at each service. Rubber ages from heat, UV, and road grime, and internal linings can swell, causing a dragging brake or a pull under braking. Many tech references suggest replacing original hoses around the 6–10 year mark, sooner if there are signs of wear. Use DOT 3 or DOT 4 brake fluid as specified on the reservoir cap and in the Daihatsu workshop manual, and bleed in the order recommended by the manual (typically the circuit furthest from the master cylinder first).

• What to watch for: cracking, checking, bulges, wetness from leaks, rusted fittings, or a hose that twists when the steering turns.
• When replacing: use ADR/LVV‑compliant hoses, new copper washers on banjo fittings, correct flare nuts, and the workshop‑specified torque. Don’t let the caliper hang on the hose, and never clamp a hose to “stop flow”.
• After fitment: bleed until clear, bubble‑free fluid flows
