Corrosion-Resistant Front Brake Wheel Cylinder with Precision-Machined Bore and

The Front Brake Wheel Cylinder (OEM Numbers: 8-97179360-0 / 8971793600) is a premium-quality, direct replacement hydraulic component designed for the front drum brake system of Isuzu NKR55 light-duty trucks.

Front brake wheel cylinder converts hydraulic pressure from the master cylinder into mechanical force to push brake shoes against the drum. Ensures balanced, effective braking for Isuzu NKR55 trucks.

• OE Quality: Manufactured to Isuzu dimensional and material specifiions for perfect fit and reliable braking
• Precision-Machined Bore: Smooth honed cylinder bore ensures consistent piston movement and long seal life
• Corrosion-Resistant: Body with anti-corrosion treatment for durability
• High-Quality Rubber Seals: EPDM cups and seals resist DOT 3/DOT 4 brake fluid, heat, and aging
• Dust Boot Included: Protects the bore from dirt and moisture
• Leak-Tested: Each cylinder is hydraulically tested for leakage before packaging
• Restores Braking Performance: Eliminates spongy pedal, fluid leaks, and uneven braking
• Direct Replacement: Matches OE mounting bolt pattern, inlet port loion, and bleeder screw position
• Cost-Effective: Affordable alternative to genuine OEM without compromising safety

Isuzu Vehicle Models:

• ISUZU NKR55 (light-duty truck)
• May also fit other Isuzu NKR/NHR models with front drum brakes - verify

Installation steps (typical for front wheel cylinder):

1. Safely lift and support the vehicle - remove the front wheel and brake drum
2. Clean the brake assembly - use brake cleaner to remove dust and debris
3. Disconnect the brake line - from the back of the old wheel cylinder using a flare nut wrench. Cap the line
4. Remove the old wheel cylinder - unbolt the two mounting bolts from the backing plate
5. Clean the backing plate mounting surface - remove old gasket/sealant
6. Compare new cylinder with old - verify bore size, bolt spacing, and port orientation
7. Install new wheel cylinder - apply a thin film of brake grease to the mounting flange. Bolt to backing plate. Torque bolts to specifiion (typically 10-15 Nm)
8. Reconnect the brake line - hand-start, then tighten with flare nut wrench. Do not cross-thread
9. Reinstall brake shoes and hardware - ensure pushrods engage properly
10. Reinstall brake drum and wheel - adjust shoes if needed
11. Bleed the brake system - start from the wheel farthest from the master cylinder
12. Check for leaks - inspect the new cylinder and line fitting
13. Test drive - ensure proper braking and no pulling
