Hi {Name}, Sample shipped: DHL 998877, ETA {date}. What's in the box: - 2 sets of your ordered SKU (P/N XXXX) - 1 set of the OE part (bought from Ford dealer, for direct comparison) - Installation hardware kit + brake fluid packet (for bleeding after install) - Detailed install guide (photos + torque specs) - Wear pattern reference chart (helps you evaluate at 500 miles) **Please do the following before signing off**: **1. Bench check (before installing)**: - Measure our pad thickness vs OE with digital calipers: should match ±0.5mm - Check backing plate flatness: place on flat surface, no rocking - Inspect friction material: should look uniform, no cracks or delamination - Weight: our pads should be within 5% of OE weight (heavier or lighter = different material density = performance concern) **2. Test vehicle install (highly recommended)**: - Install on a test vehicle (yours or an employee's) - Bed-in procedure: 6 stops from 35→5 mph (no full stops), then 6 stops from 55→15 mph, then 30-min drive without heavy braking - Drive normally for 500 miles - Return to bench: measure wear (should be minimal at 500 mi), check for cracking, uneven wear pattern **3. Noise check** (critical for reviews): - Test cold start braking (first 5 minutes of drive) — this is when cheap pads squeal - Test hard braking from 60 mph (heat + noise test) - If any squeal, tell me exactly when (cold/hot, light/heavy braking) — that data tells me if it's shim issue, friction formula, or bedding-in **4. Compare to OE**: - Feel: is the pedal firmness similar to OE? Any spongy feel = different friction compressibility - Stopping distance: informal — do our pads stop the vehicle in similar distance to OE? - Heat: after 3 hard braking events, feel the wheels (carefully). Similar heat pattern = similar friction efficiency **What "pass" looks like**: OE-comparable feel + no squeal after bed-in + minimal wear at 500 mi. If any issue found, tell me specifics and I'll re-formulate or adjust before production. Once approved, I fire the 5K order. Best, {Your Name}
