🧭 Before you start

Fits: Audi A5 Cabriolet (8F), Audi A5 (8T, 2007–2016), Audi A4 B8 (8K, 2007–2015)

• Opens: brake fluid
• Special tools named: V.A.G 1869/2

Don't miss

• Do not remove brake pedal actuator V.A.G 1869/2.
• Mark brake pads when removing them if they are to be reinstalled. Reinstall in their original position to prevent uneven braking.
• Do NOT slacken bolts (6 and 9) — Remove bolts (3) on brake carrier, holding brake carrier firmly.
• Before fitting brake pads, clean pad retaining pins (arrows) and grease lightly ETKA. Rubber parts must be kept free of grease: clean off any grease if necessary.
• Only bleed the brakes at the wheel for which the brake caliper is being renewed.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Insert brake pedal actuator V.A.G 1869/2 between brake pedal and driver's seat (depress brake pedal at least 60 mm). This closes the valves in the brake master cylinder and stops the brake fluid reservoir from running empty.
2. Raise the vehicle.
3. Remove wheels.
4. Connect hose of bleeder bottle to bleeder screw of front brake caliper.
5. Open bleeder screw on front brake caliper to release pressure from brake system.

6. Close bleeder screw (15 Nm). [Note: Do not remove brake pedal actuator V.A.G 1869/2.] — 15 Nm (11 lb-ft)
7. Disconnect brake pressure line from caliper.
8. Remove brake pads . [Note: Mark brake pads when removing them if they are to be reinstalled. Reinstall in their original position to prevent uneven braking.]
9. Remove brake caliper (7) from vehicle.
10. ⚠ Do NOT slacken bolts (6 and 9) — Remove bolts (3) on brake carrier, holding brake carrier firmly.
11. Detach brake carrier.
12. Fit brake carrier.
13. Secure brake carrier with new bolts (3). [Note: Before fitting brake pads, clean pad retaining pins (arrows) and grease lightly the parts catalogue. Rubber parts must be kept free of grease: clean off any grease if necessary.]
14. Install brake pads .
15. Connect brake pressure line (5) to caliper and tighten connection.
16. Remove brake pedal actuatorV.A.G 1869/2. [Note: Only bleed the brakes at the wheel for which the brake caliper is being renewed.]
17. Bleed brake system (if brake pressure is insufficient) .
18. Fit wheels.
19. ⚠ After installing the brake pads and before driving the vehicle, depress brake pedal firmly several times with the vehicle stationary, so that the brake pads are properly seated in their normal operating position. — Check brake fluid level and top up if necessary.
