Introduction

The 3530010-Q302 (LH) / 3530020-Q302 (RH) Rear Brake Booster is an essential pneumatic assist component for FAW New Dawei, J5P and J6 series heavy-duty trucks. Serving as the core power-assisted unit of the rear wheel braking system, it amplifies air pressure power to deliver stable and powerful braking force, effectively reducing brake pedal resistance and improving braking efficiency. Manufactured strictly in accordance with OEM standard specifications, this pair of left and right brake boosters features precise mounting dimensions, air port positions and sealing standards, supporting direct plug-and-play replacement without any modification. It perfectly solves common faults such as weak braking, slow brake response, delayed return, air leakage and insufficient braking power, ensuring safe and stable braking performance under heavy-load and long-distance driving conditions. It is a high-quality aftermarket spare part for truck repair, fleet maintenance and bulk wholesale.

Key Features

✅️Exact OEM Left & Right Matching

Standard dedicated part numbers: 3530010-Q302 for left side and 3530020-Q302 for right side. Fully compatible with FAW New Dawei, J5P and J6 heavy truck rear brake systems. 100% matches original mounting holes, air pipe interfaces and assembly parameters with zero installation error.

✅️Strong & Stable Braking Assist Performance

Adopts professional pneumatic boosting structure with stable air pressure conversion efficiency. It effectively amplifies braking power, makes the brake pedal lighter and the braking response more sensitive, completely solving the problems of weak braking and long braking distance of old boosters.

✅️Premium Sealing & Air Leakage Prevention

Equipped with high-quality wear-resistant and aging-resistant rubber diaphragms and multi-layer sealing rings. The integrated sealing process effectively isolates air leakage, maintains stable internal air pressure, and avoids braking failure caused by air pressure loss during driving.

✅️High-Strength Pressure Resistant Housing

The booster shell is made of high-strength stamping steel plate with anti-rust and anti-corrosion surface treatment. It can withstand long-term high air pressure impact and harsh road vibration, not easy to deform, crack or damage, with strong structural stability.

✅️Fast Response & Quick Reset

Optimized internal spring and air passage structure ensures instant braking output and rapid reset after braking. It prevents dragging brake, brake drum overheating and tire abnormal wear, effectively improving driving safety and tire service life.

✅️Adaptable to Harsh Working Conditions

Professional dustproof, waterproof and anti-aging design adapts to complex road environments such as muddy roads, mountain roads and long-distance freight. It resists temperature changes and environmental erosion, with low failure rate and long service life.

✅️Direct Installation & High Cost Performance

Completely consistent with original vehicle assembly standards, no drilling, cutting or debugging required for replacement, saving maintenance time and labor cost. Strictly tested before delivery to replace faulty original parts perfectly and restore optimal braking performance.
