Bleeding brake system without brake filling and bleeding equipment — AUDI

🧭 Before you start

Fits: Audi A6/A7 C7 (4G, 2011–2018); platform code 4X

• Opens: brake fluid

Don't miss

• Fill up brake fluid reservoir to "“MAX”" mark.
• Use suitable bleeder hose. It must sit tightly on the bleeder screw so that no air can enter the brake system.
• Press brake pedal slowly to avoid formation of bubbles.
• To prevent brake fluid from overflowing from the reservoir, the brake fluid level must not be above the "“MAX”" mark (1).

🔩 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. Fill up brake fluid reservoir to "“MAX”" mark.
2. Detach dust caps (front) (1) on both sides.
3. Detach dust caps (rear) (1) on both sides. [Note: Use suitable bleeder hose. It must sit tightly on the bleeder screw so that no air can enter the brake system.]
4. Fit bleeder hose of reservoir onto bleeder screw.
5. Build up pressure in brake system by pumping brake pedal. [Note: Press brake pedal slowly to avoid formation of bubbles.]

6. Once pressure has built up, keep brake pedal depressed.
7. With bleeder hose attached, leave bleeder screw open until the brake fluid which emerges is clear and free from bubbles.
8. Keep pedal depressed and close bleeder screw.
9. Release brake pedal and wait approx. 2 seconds to allow brake fluid to flow in from brake fluid reservoir.
10. Repeat procedure until emerging brake fluid is clear and free from bubbles.
11. Tighten bleeder screw, detach bleeder hose and fit protective cap on bleeder screw.
12. Repeat bleeding procedure in stated sequence at other brake calipers.
13. Fill brake fluid reservoir up to "“MAX”" mark (depending on degree of pad wear) and screw on filler cap. [Note: To prevent brake fluid from overflowing from the reservoir, the brake fluid level must not be above the "“MAX”" mark (1).]
14. Start engine and check brake pedal travel and brake pedal pressure.
15. In the event of excessive pedal travel, check brake system for leaks and/or repeat bleeding procedure.
