Let’s get straight to it—this isn’t just a “vacuum device” in your Chery
Tiggo 7 Pro. It’s the
core power-assist component of the brake system: a precision-engineered mechanical/electric pump, typically made of high-strength aluminum alloy and engineering plastic. Mounted on the engine or near the brake master cylinder, it generates and stores vacuum pressure to assist the brake operation. Think of it as a “brake effort reducer”—when you press the brake pedal, it uses vacuum force to amplify the pressure applied to the brake master cylinder, making braking lighter and more responsive. Without it, the brake pedal becomes extremely heavy, requiring much greater force to stop the vehicle, seriously endangering driving safety.
This brake vacuum pump is
exclusively tailored for Chery Tiggo 7 Pro—always confirm your vehicle’s VIN and engine model to ensure a perfect match! It’s calibrated to the Tiggo 7 Pro’s brake system specs: its vacuum output matches the brake master cylinder’s demand (ensuring consistent assist force), its mounting structure aligns with the engine bay layout (stable installation), and its working pressure syncs with the vehicle’s braking performance requirements. Opt for generic pumps? You’ll face issues: insufficient vacuum (heavy brake pedal), unstable pressure (spongy brake feel), or poor durability (sudden failure).
As a vital part of the Tiggo 7 Pro’s brake system, it undertakes three key roles to guarantee braking reliability:
Provide brake power assist: It creates and maintains sufficient vacuum pressure (usually 0.06–0.08MPa). When the brake pedal is pressed, the vacuum acts on the brake booster diaphragm, multiplying the force the driver applies to the pedal—reducing pedal effort by 60–80%.
Stabilize braking performance: It maintains stable vacuum pressure regardless of engine operating conditions (e.g., low idle speed or high load). This ensures consistent brake pedal feel and braking force, avoiding situations where braking becomes heavier suddenly.
Backup safety guarantee: For electric vacuum pumps (if equipped), it works independently of engine vacuum. Even if the engine stalls temporarily, it can maintain vacuum for 1–2 emergency brake applications, providing a last line of safety defense.

This B213541110 brake vacuum pump only works for Chery Tiggo 7 Pro—wrong fit = brake failure risks:
Fits These Models: All Chery Tiggo 7 Pro variants, especially those matching the specified engine model (confirm via VIN and engine code). It aligns with the vehicle’s brake booster size, vacuum demand, and mounting points.
Won’t Fit These:
Other Chery models: e.g., Tiggo 7 (non-Pro), Tiggo 8 Pro—different brake system layouts, vacuum requirements, and mounting structures (can’t install or function).
Non-Chery vehicles: Even if similar in appearance, brake system pressure specs and connection interfaces differ drastically (no functional compatibility).
Tiggo 7 Pro with modified brake systems: Aftermarket brake boosters or master cylinders may have altered vacuum needs—original pump can’t provide proper assist.
Replacing the brake vacuum pump involves brake system sealing and pressure testing—DIY is extremely dangerous:
Vehicle prep: Techs disconnect the battery (for electric pumps), remove engine covers (if needed), and disconnect the vacuum hose and electrical connector (or mechanical drive linkage) from the old pump.
Remove old pump: They unbolt the old pump from its mounting bracket, carefully cleaning the mounting surface to remove debris or old gasket residue.
Install new pump: They place B213541110 onto the bracket, replace with a new sealing gasket, bolt it to Chery’s exact torque specs (avoids leakage), and reconnect hoses/connectors.
Vacuum test: Critical step—techs use professional equipment to test the pump’s vacuum output and leakage rate. They also test the brake pedal feel to ensure normal assist.
Road test: A short test drive confirms consistent braking performance, no abnormal pedal feel, and no warning lights on the dashboard.
Check for vacuum leaks: Every 20,000km, inspect hoses and connections for cracks or looseness. A hissing sound near the pump indicates a leak—repair or replace parts immediately.
Monitor brake pedal feel: If the pedal becomes abnormally heavy or spongy, have the pump’s vacuum output checked. Insufficient vacuum means the pump may be failing.
Maintain engine oil (for mechanical pumps): Ensure engine oil is at the correct level and changed regularly. Lack of oil can damage the pump’s internal mechanical parts.
Avoid overloading: Excessive vehicle load increases braking demand, putting extra strain on the vacuum pump. Drive within the Tiggo 7 Pro’s load capacity.

This is an exclusive brake vacuum pump for Chery Tiggo 7 Pro (confirm VIN/engine model for fitment). Made of high-strength materials, it’s mounted on the engine or near the brake master cylinder, serving as the core brake power-assist component.
Its key functions: Generate 0.06-0.08MPa vacuum to reduce brake pedal effort by 60-80%, maintain stable braking performance under different engine conditions, and provide 1-2 emergency brake assists (for electric types) if the engine stalls.
It only fits Tiggo 7 Pro, incompatible with other Chery models (e.g., Tiggo 7, Tiggo 8 Pro) or non-Chery vehicles. Installation requires certified techs with vacuum testing; maintenance involves leak checks, pedal feel monitoring, and proper oil maintenance (mechanical types). Original parts are essential—aftermarket ones risk leakage or insufficient assist, endangering safety.
