This master cylinder distribution block with double reservoir (OEM 3151-3505010-20) is designed for UAZ Bukhanka Modern (2.7L Injection) and Hunter & 469 (2.7L Injection) models. It serves as the central hydraulic unit of the brake system, dividing brake fluid between the front and rear circuits while housing two separate reservoirs in a single assembly for enhanced safety and reliability.
Why choose this master cylinder block?
Engineered to match UAZ’s original dual-circuit brake system design, this part ensures stable hydraulic distribution and consistent braking performance under both everyday and demanding conditions. By using a two-reservoir layout, it increases safety redundancy, ensuring that one circuit remains operational even in the event of fluid loss in the other. It is a direct-fit replacement requiring no modifications to the brake plumbing.
Technical details:
Material: Cast iron body (some later variants in aluminum), with twin plastic reservoirs
Configuration: Dual outlet design for front and rear brake circuits
OEM reference: 3151-3505010-20
Weight: Approx. 2.0–2.3 kg (cast-iron version)
Condition: NEW replacement unit built to factory specifications
Compatible models:
Bukhanka Modern (2.7L Injection)
Hunter & 469 (2.7L)
Installation tips:
Mount directly to the firewall using factory fastener points. Connect front and rear brake lines to the correct outlets with new sealing washers. Fill reservoirs with DOT-approved brake fluid, then bleed both brake circuits thoroughly to remove air. After installation, verify pedal firmness and check all connections for leaks under pressure.
When to replace or upgrade?
Replace this master cylinder if you experience spongy brake pedal response, visible fluid leakage, uneven braking, or internal seal wear. Recommended replacement interval is around 100,000 km, or sooner if performing a full brake system service, restoring a vehicle, or ensuring maximum braking reliability.
