Product Description
ISUZU Rubber Brake Hose Assembly 0201080006 YIMI OEM Fit
Brake Hose Assembly YIMI Rubber Brake Flex Hose with Metal Fittings for ISUZU NKR NPR NQR 4JB1 4HF1 — Verified OEM Fit EPDM Hydraulic Brake Line
Product Overview
The Brake Hose Assembly is a verified direct-fit replacement for ISUZU NKR / NPR / NQR / ELF / 700P light and medium-duty trucks equipped with 4JB1 / 4HF1 / 4HG1 / 4HK1 diesel engines. This brake hose is a critical component of the hydraulic brake system, responsible for transmitting brake fluid pressure from the chassis hard lines to the wheel cylinder or brake caliper while allowing suspension articulation and steering movement.
Working Principle
The brake hose is the flexible portion of the vehicle's brake line that connects the rigid metal brake pipes on the chassis to the brake caliper or wheel cylinder at each wheel. Its flexibility allows the hose to accommodate suspension travel, steering movement, and vibration without compromising brake fluid pressure transmission. The YIMI brake hose features a multi-layer EPDM rubber construction with high-tensile synthetic fiber reinforcement for burst strength and durability. The zinc-plated steel fittings at both ends provide corrosion resistance and reliable sealing.
Failure Symptoms
Replace the brake hose when any of these symptoms appear:
- Visible cracks, bulges, or abrasions on the hose surface — external damage compromises burst strength and can lead to sudden hose failure.
- Brake fluid leakage at the hose fittings — visible fluid traces at the crimped fitting connections indicate seal failure.
- Spongy or soft brake pedal — internal hose deterioration can cause expansion under pressure, reducing braking effectiveness.
- Brake pedal sinks to the floor — a ruptured or severely weakened hose causes loss of hydraulic pressure.
- Uneven braking or vehicle pulling to one side — a partially blocked or kinked hose restricts fluid flow to one wheel.
- Hose feels wet or shows signs of weeping — moisture around the hose indicates fluid seepage through the rubber casing.
⚠️ Critical Inspection Note: ISUZU service manuals require that brake hoses be inspected for cracks, leaks, and corrosion at every brake service interval. Always replace brake hoses in pairs (left and right) to maintain balanced braking performance. Use a flare nut wrench to avoid damaging the fitting hex. Brake hose fitting torque is typically 15–20 N·m (11–15 lb·ft) — verify against your specific ISUZU workshop manual. After installation, bleed the brake system thoroughly to remove all air.

⚠️ Important Fitment Notes:
- Brake hoses vary significantly by position (front/rear, left/right) and model year. Confirm the hose length, fitting type (flare or banjo), and thread size against your original component before ordering.
- OEM cross-reference: Common ISUZU brake hose OEM numbers include 8-98080168-0 / 8980801680 (Front, 700P/NQR), 8942573360 / 8-94257336-0 (Front, 700P/NKR/NHR), and 8971348300 (Brake Master Cylinder).
- Always replace brake hoses in pairs (left and right) to maintain balanced braking.
- Brake hose fitting torque is typically 15–20 N·m (11–15 lb·ft) — verify against your ISUZU workshop manual.
- After installation, bleed the brake system thoroughly to remove all air.
- For right-hand drive (RHD) vehicles, verify clearance and routing. Refer to the ISUZU workshop manual for the correct procedure.
📌 Fitment Verification: To ensure 100% accurate matching, please provide the VIN or chassis number before ordering. We will verify it through the ISUZU global EPC system.

Installation & Maintenance Recommendations
⚠️ IMPORTANT: Brake system service must be performed by a qualified technician. Always disconnect the battery negative terminal and relieve brake system pressure before removing the brake hose. Never reuse old brake hoses.
Installation Guidelines — Reference ISUZU Workshop Manual
- Preparation: Raise the vehicle on a hoist. Remove the wheel. Clean the brake hose and surrounding area thoroughly.
- Removal: Use a flare nut wrench to disconnect the brake hose from the hard line. Remove the retaining clip or bracket bolt. Disconnect the hose from the caliper or wheel cylinder.
- Inspection: Inspect the hard line fitting for corrosion or damage. Inspect the caliper or wheel cylinder inlet for debris. Clean all mating surfaces.
- Installation: Position the new brake hose. Hand-thread the fittings first to avoid cross-threading. Tighten the fitting to 15–20 N·m (11–15 lb·ft) using a flare nut wrench. Install the retaining clip.
- Bleeding: Bleed the brake system thoroughly to remove all air. Check for leaks at all connections.
- Pedal Test: Pump the brake pedal several times to verify a firm pedal before road testing.
- Road Test: Perform a road test at low speed to verify proper braking performance.
Recommended Torque Values:
| Fastener | Torque |
|---|---|
| Brake Hose Fitting | 15–20 N·m (11–15 lb·ft) |
| Retaining Clip Bolt | Per ISUZU workshop manual specification |
| Wheel Lug Nuts | Per ISUZU workshop manual specification |
