FORD BRAKE DISC

Grey Cast-Iron G3000 – cast, CNC-machined and dynamically balanced to Ford OE standards for exact fit, strong bite and long service life across EcoBoost, ST and Ranger platforms.

Manufactured in an IATF-16949 facility that also ships to Ford assembly lines worldwide.

1. 100 % FORD OE GEOMETRY

– CNC-turned outer Ø, thickness, bolt circle and hat height to Ford blueprint—installs without spacers, shims or software updates.

– Hub pilot and ABS tone-ring teeth held ± 0.01 mm—zero lateral run-out, no brake judder or ABS/ESC codes.

2. GREY CAST-IRON G3000 COMPOSITION

– 3.3 % C, 2.0 % Si, 0.7 % Mn, ≤ 0.15 % P, ≤ 0.12 % S—identical chemistry used on Focus, Fiesta, Kuga, Ranger, F-150.

– Pearlite matrix, 200-230 HB: high wear resistance, excellent thermal conductivity and natural NVH damping for Ford-class comfort.

3. HIGH-PERFORMANCE VENTILATED CORE

– 48 directional vanes increase airflow 18 %, cutting peak temperature 70 °C during repeated 100-0 km/h stops.

– Single-piece casting—no welded seams to fail under ST or Raptor track-day thermal cycles.

4. SURFACE FINISH & PRECISION BALANCE

– Non-directional swirl, Ra ≤ 1.6 µm—beds-in within 20 stops, no greenfade.

– Dynamic balanced ≤ 0.8 g—steering-wheel shake free at Ford’s 200 km/h (124 mph) limit (Focus ST).

5. ANTI-CORROSION COATING

– Full-surface Geomet® or electro-zinc layer—144 h salt-spray per ASTM B117, survives northern winters and coastal humidity.

– Friction faces uncoated for immediate use; protective oil film burns off on first brake application.

6. QUIET, LOW-DUST DESIGN

– Precision dual-radius chamfers plus 0.30 mm under-cut slots prevent pad-knock and squeal.

– Optimised for Ford low-met and ceramic formulations—low dust, no black rims on ST or RS wheels.

7. VALIDATION TESTS

– 500-cycle AK-Master (200-50 km/h, 5 kW power) wear ≤ 0.30 mm—within Ford 0.5 mm limit.

– Thermal shock: 600 °C → 20 °C water quench, 50 cycles—no surface cracks, distortion < 0.03 mm.

8. SERVICE LIFE & FITMENT

– 80 000–100 000 km normal street use; 40 000 km severe duty (taxi, police, mountain routes).

– Direct replacement for selected Ford cars, SUVs and pickups—see reverse for engineering number / VIN list.

– Replace in axle pairs and use Ford-specified pads for optimum pedal feel and ESC compatibility.

INSTALLATION NOTE

Clean hub face with wire brush, apply thin anti-seize on contact shoulders only, torque wheel nuts to 150 N·m (M14 trucks) or 120 N·m (M12 cars) in star pattern.

Bed-in: 8 moderate stops 100 km/h → 30 km/h with 30 s cooling between each.
