• Special tools named: V.A.G 1869/2

Don't miss

• Do not remove brake pedal actuator V.A.G 1869/2.
• Brake hose in brake caliper, 16 NmBrake pressure line to brake hose: 16 Nm
• 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. Remove brake pads .
8. Disconnect brake hose (8) from brake caliper.
9. Remove bolts (13) (hold brake caliper firmly). [Note: Renew bolts (13).]
10. Attach brake caliper and secure with new bolts (13).
11. Secure brake hose (8) to brake caliper. [Note: Brake hose in brake caliper, 16 NmBrake pressure line to brake hose: 16 Nm]
12. Install brake pads .
13. Remove brake pedal actuatorV.A.G 1869/2. [Note: Only bleed the brakes at the wheel for which the brake caliper is being renewed.] [Note: Bleed each brake caliper at both bleeder screws.Tightening torque for bleeder screw: 15 Nm]
14. Bleed brake system (if brake pressure is insufficient) .
