First, let’s break down its core role: the
Chery Tiggo7 Pro Rear Brake Disk 204000479AA isn’t just a “metal disk”—it’s the
key friction component of the rear brake system that turns your car’s kinetic energy into heat to slow or stop the vehicle. Think of it as a smooth, durable metal disk mounted on the Tiggo7 Pro’s
rear wheel hub, working with the rear brake calipers and pads. When you press the brake pedal, the calipers squeeze the brake pads against this disk—creating friction that slows the rear wheels (and the whole car). Without it, the rear brakes can’t generate enough stopping force—risking longer braking distances and safety hazards.
This rear brake disk is
exclusively engineered for the Chery Tiggo7 Pro’s rear axle—always confirm with your vehicle’s VIN! It’s tailored to fit perfectly: its diameter and thickness match the Tiggo7 Pro’s
rear brake caliper size (no loose or tight fits), its mounting holes align with the rear wheel hub (no drilling), and its friction surface is calibrated to work with the Tiggo7 Pro’s factory brake pads (avoids premature wear). A generic disk? You’ll face issues: it’ll be too thin (overheats fast), mismatched with the caliper (causes brake noise), or unbalanced (leads to steering/shaking when braking)—all compromising safety.
Its role is critical for braking performance—here are 4 key tasks it performs for your Tiggo7 Pro:
Create stopping friction: When brake pads press against the disk’s surface, the friction between them slows the rear wheel rotation. This works with the front brakes to give balanced, reliable stopping power (especially in wet or slippery conditions).
Dissipate heat quickly: Braking generates intense heat (up to 600°C), and this disk’s design (like internal cooling fins) lets heat escape fast. Overheating causes “brake fade” (loss of stopping power)—so good heat dissipation keeps brakes effective even during frequent braking (e.g., downhill drives).
Maintain smooth braking: Its surface is precision-machined to be perfectly flat and smooth. A uneven surface causes “brake judder” (steering or pedal shaking when braking)—this disk’s flatness ensures a quiet, smooth stop every time.
Withstand heavy use: Made of high-strength metal, it resists wear from constant friction with brake pads. It also handles the weight of the Tiggo7 Pro (and passengers/luggage) without warping—staying reliable for tens of thousands of kilometers.

This 204000479AA rear brake disk is only for the Chery Tiggo7 Pro’s rear axle—wrong fit = brake failure:
Brake components need precise installation—DIY can lead to brake failure:
Remove old disk: Technicians lift the Tiggo7 Pro, remove the rear wheel, then take off the rear brake caliper (and secure it to avoid damaging the brake line). They then unbolt the old disk from the rear hub.
Prep new disk: They clean the hub’s mounting surface (remove rust or debris), apply anti-seize compound (prevents the disk from sticking to the hub), and check the new disk for any damage (e.g., cracks).
Mount and align: They bolt 204000479AA to the hub (using a torque wrench to follow Chery’s exact specs—too loose = wobble; too tight = warping), then reattach the brake caliper and pads.
Test brakes: They pump the brake pedal to restore pressure, then take a short test drive to check for noise, judder, or soft pedals—ensuring the brakes work smoothly.
Check wear every 10,000 km: Measure the disk’s thickness (replace if it’s thinner than Chery’s minimum spec—usually 2–3mm less than the original). A worn disk can’t generate enough friction.
Clean regularly: Wipe the disk’s surface with brake cleaner (remove brake dust or oil—grease on the disk reduces friction and stopping power).
Avoid harsh braking: Frequent hard stops overheat the disk (causes warping). Brake gently when possible to extend its life.
Replace in pairs: Always replace both rear brake disks at the same time (even if one looks less worn). Mismatched wear causes unbalanced braking (pulls the car to one side).

Exclusive to Chery Tiggo7 Pro’s rear axle (confirm via VIN), this disk is key for safe braking: it works with brake pads to create friction (slowing the car), has internal cooling fins to dissipate heat (preventing brake fade), and features a smooth surface for quiet, steady stops.
It fits the Tiggo7 Pro’s rear calipers and hub perfectly—aftermarket disks wear fast, warp easily, or cause noise. Maintain by checking thickness every 10,000 km, replacing in pairs, and avoiding harsh braking. Only the original ensures reliable stopping power.
