Road-Test Tai 7 Brakes, Regeneration and Chassis Behavior

Regeneration can reduce ordinary friction-brake use, while vehicle mass, tyres and accessories influence stopping and chassis behavior. Test the identified PHEV or EV under recorded conditions rather than calling every unfamiliar response normal.

CONNECTED DECISIONS

Carry this evidence into the next relevant route.

Keep chassis findings inside the used-vehicle inspection. Price support through the maintenance and parts plan.

01CHECKPOINT

Set a static safety gate

Confirm tyre markings and pressures, wheel damage, visible disc and pad condition, fluid evidence, suspension and steering play, accessory security and warning lamps. Unsafe findings stop the dynamic test.

Evidence recordstatic tyre and brake record. Date it, identify the source, and state unresolved limits.
02CHECKPOINT

Record state and route

Note propulsion, battery state, drive and regeneration mode, temperature, road surface, load, tyre pressure and speed range. Use a legal route covering parking, low-speed control, steady cruise, progressive acceleration and braking.

Evidence recordroute and energy-state log. Tie it to this VIN and describe the observed outcome.
03CHECKPOINT

Observe propulsion transitions

For PHEV, record engine entry, hybrid transitions and braking feel across available energy states. For EV, record response and regeneration without importing assumptions from a different battery or software version.

Evidence recordpre- and post-drive diagnostics. Name the test conditions, reviewer and remaining uncertainty.
04CHECKPOINT

Expose friction-brake condition

Under safe conditions, observe pedal consistency, pull, vibration, noise and control at different speeds. Do not disable safety systems or provoke emergency intervention simply to create a test.

Evidence recordrepeatable chassis observations. Keep the original record and mark when it expires.
05CHECKPOINT

Connect chassis symptoms

Drift or vibration can involve tyres, wheels, alignment, bearings, suspension, steering, brakes, load or accessories. Preserve measurements and diagnosis instead of replacing the easiest visible component.

Evidence recordpost-repair road-test result. Reconfirm it at custody and document any material change.
06CHECKPOINT

Recheck after heat and repair

Scan after the drive, inspect odor, leaks and temperature differences, then repeat the affected route after corrective work. An invoice without a comparable retest does not close the behavior.

Evidence recordpost-repair road-test result. Repeat the affected evidence after corrective work and before custody changes.

HANDOVER FILE

Evidence to retain before the decision closes

Keep only material that answers this route, exposes uncertainty or preserves condition at a custody change.
  1. static tyre and brake record
  2. route and energy-state log
  3. pre- and post-drive diagnostics
  4. repeatable chassis observations
  5. post-repair road-test result

BUYER SCENARIO

Apply the evidence to a realistic operating case.

Test a lightly used Tai 7 whose friction brakes show corrosion after storage and a higher-mileage vehicle with even wear and stable measurements. The lower odometer does not win until braking condition is resolved.

Stress the result by assuming “Observe propulsion transitions” reveals a conflict, “Expose friction-brake condition” is delayed, or “Connect chassis symptoms” changes before custody. Rework the cost, timing and stop condition using pre- and post-drive diagnostics, repeatable chassis observations, post-repair road-test result. A different VIN, propulsion route or installed configuration starts a new candidate record. The conclusion for Tai 7 Brakes, Regeneration and Road-Test Guide must explain how static tyre and brake record and route and energy-state log support or limit the selected route.

CLOSE THE FILE

Make the result dated, conditional and transferable.

For Tai 7 Brakes, Regeneration and Road-Test Guide, reconcile static tyre and brake record, route and energy-state log, pre- and post-drive diagnostics, repeatable chassis observations, post-repair road-test result. Mark each item verified, seller-stated, estimated or unresolved, and put a responsible person and expiry date beside the open work. Keep commercial rows separate so a change in one assumption does not silently rewrite the whole conclusion.

Immediately before payment or handover, repeat “Set a static safety gate” and confirm that the candidate still matches the reviewed record. Preserve the VIN, odometer, visible condition, keys, documents and relevant energy state. If the vehicle or a material specification changes, close this file and begin a new one.

OFFICIAL REFERENCE BOUNDARY

Use current China-market material as a reference, not vehicle proof.

Fangchengbao may revise equipment, software and specifications. Match official information to the production record and actual installed hardware. Review the official Fangchengbao Tai 7 reference, then verify the candidate and destination independently.

BUYER QUESTIONS

Questions to close before approval

Does regeneration prove friction brakes are healthy?

No. Inspect and safely exercise the friction system.

Should PHEV and EV feel identical?

No. Identify propulsion, software, state and mode first.

What stops the road test?

Unsafe tyres or brakes, severe warnings, leakage, unstable temperature or loss of control.
