01

Record every corner

Photograph wheel and tyre identity, then measure accessible pad material and disc condition against version-correct limits. Note scoring, lips, cracking, heat marks, corrosion, contamination, hoses and caliper condition. One clean front wheel cannot represent the axle, and low mileage cannot rule out storage corrosion.

For record every corner, place four-corner brake measurements beside the candidate record and test whether all four corners are recorded. Tie the result to audi q3 brake, parking brake and road-test checks, the exact VIN, capture date, original market and operating conditions. Describe what was inspected, which source supplied the claim, what remains inaccessible and how the finding changes acceptance, repair scope or delivered cost. This prevents a nearby listing, another generation or an undated seller statement from becoming evidence for the vehicle under review.

02

Verify fluid and service evidence

Check dated brake-fluid work and inspect for leakage or damaged lines. Audi publishes general service guidance but directs exact-model questions to vehicle-specific information. Do not copy a universal replacement threshold into the report; record the measured condition, correct specification and due basis for the VIN.

For verify fluid and service evidence, place fluid and service record beside the candidate record and test whether hybrid regeneration stays distinct. Tie the result to audi q3 brake, parking brake and road-test checks, the exact VIN, capture date, original market and operating conditions. Describe what was inspected, which source supplied the claim, what remains inaccessible and how the finding changes acceptance, repair scope or delivered cost. This prevents a nearby listing, another generation or an undated seller statement from becoming evidence for the vehicle under review.

03

Exercise the electronic parking brake

Apply and release it on level ground and an appropriate gradient, observe warning state and listen for abnormal operation. Test auto-hold only where fitted and under safe conditions. Save relevant faults before resets. A switch response alone does not prove balanced rear braking or intact mechanisms.

For exercise the electronic parking brake, place parking-brake diagnostic test beside the candidate record and test whether faults are saved before resets. Tie the result to audi q3 brake, parking brake and road-test checks, the exact VIN, capture date, original market and operating conditions. Describe what was inspected, which source supplied the claim, what remains inaccessible and how the finding changes acceptance, repair scope or delivered cost. This prevents a nearby listing, another generation or an undated seller statement from becoming evidence for the vehicle under review.

04

Run a controlled road test

State road, speed, load, weather, tyre pressure and initial brake state. After safe bedding, observe pedal consistency, pull, vibration, noise, ABS or stability warnings and low-speed release. Keep regenerative behaviour on hybrid versions separate from friction-brake condition and avoid aggressive testing on an unsafe candidate.

For run a controlled road test, place controlled cold and warm road notes beside the candidate record and test whether repair receives a comparable retest. Tie the result to audi q3 brake, parking brake and road-test checks, the exact VIN, capture date, original market and operating conditions. Describe what was inspected, which source supplied the claim, what remains inaccessible and how the finding changes acceptance, repair scope or delivered cost. This prevents a nearby listing, another generation or an undated seller statement from becoming evidence for the vehicle under review.

05

Connect braking to chassis evidence

Uneven braking can interact with tyres, wheel damage, bearings, suspension, alignment or previous impact. Inspect those systems before assigning every symptom to discs. If vibration occurs only in a defined speed or temperature window, record that condition so the workshop can reproduce it.

06

Close work with measurements and retest

Price parts, sensors, fluid, labour, coding or adaptation where required, and any axle-pair replacement. After work, retain final measurements, scan, parking-brake operation and comparable road-test notes. Shipping acceptance should require stable braking and adequate tyre condition for terminal handling.

07

Condition file close-out

Close this specific file by placing four-corner brake measurements, fluid and service record and parking-brake diagnostic test in one dated candidate record. The reviewer should be able to confirm that all four corners are recorded and that hybrid regeneration stays distinct. Name the person or provider responsible for every unresolved point, add a realistic cost or consequence, and state what evidence will change the decision. If the VIN, version, condition or destination basis changes, reopen this file instead of carrying the previous conclusion into a different purchase. Give the buyer a short approval note that names the exact Q3 generation, body, original market and powertrain, identifies the strongest evidence, and lists any limit that remains untested. That note becomes the handover boundary for the next commercial or technical step.
