Small Brake Caliper Guide Sleeve JAC6490-008 — OEM replacement for JAC N35, N56, N75, N80, N120, and N350 light truck models.
The small brake caliper guide bushing with part number JAC6490-008 is a direct-fit replacement for multiple JAC light truck models, including N35, N56, N75, N80, N120, and N350. It is installed in the front brake caliper bracket, guiding the caliper slide pin to ensure smooth, even brake pad wear.
The guide bushing provides a low-friction sliding surface for the caliper pin. When the brake pedal is applied, the caliper must slide freely to clamp the disc evenly. A worn or seized bushing causes the caliper to stick, leading to uneven pad wear, dragging brakes, or reduced braking performance.
- ✓Application Verified (Russian Catalogs): Multiple independent Russian suppliers list JAC6490-008 as the small caliper guide bushing for JAC N56 and related models.
- Name Conflict Warning: Some English pages title this as “SLEEVE; CONV PILOT” but their content is irrelevant (steering rod text). Do not rely on that title.
- Material & Dimensions Pending: No public data for inner/outer diameter, length, or material grade. Request from supplier: dimensional drawing and material certificate.
- Installation Success Rate Pending: No repair order statistics available.
When this guide bushing fails, the following symptoms may appear:
- Uneven or accelerated brake pad wear (one pad thinner than the other)
- Brake drag or overheating after driving
- Vehicle pulls to one side during braking
- Squealing or clicking noise from the brake caliper area
- Visible corrosion, cracking, or excessive clearance on the bushing
