Brilliance H330 Brake Pump – Part No.: 3497029-2J10

Let’s cut to the chase—this isn’t just a “metal part” in your Brilliance H330’s engine bay. It’s the key hydraulic core of the vehicle’s brake system: a durable, precision-engineered component usually made of cast iron or high-strength aluminum alloy. Mounted in the engine bay (near the driver’s side firewall), it connects to the brake pedal via a pushrod and links to the brake lines. Think of it as the “brake force converter”—without it, pressing the brake pedal would do nothing: it turns your foot’s pressure into hydraulic fluid pressure, which pushes the brake calipers/pads to stop the wheels.

This brake pump is made exclusively for Brilliance H330—always check your vehicle’s VIN to confirm it fits! It’s tailored to the H330’s specs: its hydraulic cylinder size matches the brake system’s pressure needs (ensures strong, responsive braking), its mounting points align perfectly with the H330’s firewall (no forced adjustments), and its seal design works with the H330’s brake fluid type (prevents leaks). Grab a generic pump instead? You’ll run into trouble: wrong cylinder size (soft or unresponsive brakes), poor seals (fluid leaks), or misfit (can’t connect to pedal or lines).

1. Core Jobs: Convert Force, Drive Brakes & Ensure Safety

As the “heart” of the H330’s brake system, it does three critical jobs that keep you safe on the road:

Turn pedal pressure into hydraulic force: When you press the brake pedal, it pushes the pump’s internal piston. This squeezes brake fluid in the pump’s cylinder, turning gentle foot pressure into high hydraulic pressure (up to hundreds of PSI) that flows through the brake lines.

Power all four brakes: The pressurized fluid from the pump travels to the front and rear brake calipers/wheel cylinders. This pressure pushes the brake pads against the rotors (or shoes against drums), creating friction that slows or stops the H330—no pump = no braking force.

Maintain brake pressure (prevent fade): It keeps consistent pressure in the brake lines, even during repeated hard braking (like stopping quickly multiple times). This prevents “brake fade” (when brakes lose strength from overheating) and ensures reliable stopping every time.

This 3497029-2J10 brake pump only fits Brilliance H330—wrong fit = dangerous brake failure:

Fits These: All Brilliance H330 variants (matches the brake system’s hydraulic specs, firewall mounting, and pedal linkage—confirm with your VIN).

Won’t Fit These:

Other Brilliance models: Like Brilliance H220 or H530—different brake system pressure needs and mounting positions (pump can’t drive brakes properly).

Non-Brilliance vehicles: Even if similar in shape, brake line layouts and pedal linkage differ (no functional compatibility, risking no brakes).

H330 with modified brakes: Aftermarket big brake kits need matching high-pressure pumps—original pump can’t meet demand.

Installation & Upkeep (Safety First—Pros Only!)

Installation: Must Be Done by Certified Technicians

Replacing this brake pump is not a DIY job—mistakes cause brake failure:

Prep: Techs drain old brake fluid, disconnect the brake lines and pushrod from the old pump, then unbolt the pump from the firewall.

Install new pump: They mount 3497029-2J10 to the H330’s firewall (aligning pushrod and line ports), reconnect lines, and fill the reservoir with Brilliance-specified brake fluid.

Bleed the system: Critical step—techs remove air from the brake lines (air = spongy brakes). They pump the pedal and open bleed valves until no air bubbles come out.

Test: They check for leaks, test brake pedal feel (should be firm, no sponginess), and do a low-speed test drive to confirm reliable stopping.

Maintenance: Easy Checks to Keep Brakes Safe

Check fluid level: Every month, look at the reservoir—fluid should be between “MIN” and “MAX” marks. Low fluid means a leak (fix immediately).

Inspect for leaks: Look around the pump and brake lines for wet spots (brake fluid is clear/yellowish and slippery). Leaks = loss of pressure = dangerous.

Replace fluid regularly: Change brake fluid every 2 years (fluid absorbs moisture, which corrodes the pump and reduces braking power).

Watch for warning signs: Spongy pedal, longer stopping distance, or fluid leaks—these mean the pump needs inspection (don’t drive until fixed).

Summary: Brilliance H330 Brake Pump (3497029-2J10)

This is an exclusive hydraulic core for Brilliance H330 (confirm VIN for fitment). Made of cast iron or high-strength aluminum alloy, it’s mounted near the driver’s side firewall in the engine bay, connecting the brake pedal (via a pushrod) and brake lines.

Its core functions: Convert foot pressure into high hydraulic pressure (up to hundreds of PSI) to drive front/rear brakes; maintain consistent pressure to prevent brake fade; ensure reliable stopping by pushing calipers/pads against rotors.

It only fits Brilliance H330— incompatible with other Brilliance models (e.g., H220, H530), non-Brilliance vehicles, or H330 with modified brakes. Installation needs certified techs (fluid draining, bleeding air); maintenance involves monthly fluid checks, leak inspections, 2-year fluid replacement, and addressing spongy pedals/long stopping distances. Original parts are critical—aftermarket ones risk cracking, leaking, or mismatched pressure, endangering safety.
