How to Replace Brake Fluid for Audi Q5?
3 Answers
Audi Q5 brake fluid replacement method is: 1. Open the car hood and locate the brake fluid reservoir; 2. After opening, use a syringe to extract all the brake fluid from the reservoir; 3. Add new brake fluid. The Audi Q5 is classified as a mid-size SUV, equipped with a 2.0T L4 engine featuring turbocharged intake. The dimensions of the Audi Q5 are 4629mm in length, 1898mm in width, and 1655mm in height, with a wheelbase of 2807mm. It comes with an 8-speed automatic transmission and is configured as a 5-door, 5-seater SUV. Brake fluid, also known as brake hydraulic fluid or brake liquid, is formulated from refined diesel distillates combined with thickeners and antioxidants.
I replaced the brake fluid for my Q5 by myself, and the whole process requires two people to cooperate. Prepare 1 liter of DOT4-standard brake fluid, a transparent plastic hose, and an oil collection container. First, park the car on level ground and engage the handbrake, then use a jack to lift the car but remember to secure it with professional stands. The operation sequence is right rear wheel, left rear wheel, right front wheel, and then left front wheel, starting from the wheel farthest from the fluid reservoir. I connected the hose to the drain port and led it into the container, while my friend repeatedly pumped the brakes inside the car and then held them down. I quickly loosened the drain screw to release the old fluid until the new fluid color appeared in the transparent tube, then tightened it. Throughout the process, ensure the fluid level in the reservoir does not drop below the minimum mark. After replacement, remember to press the brake pedal deeply more than ten times to expel air from the system, and finally check all connections for leaks. Brake fluid is corrosive, so be sure to wear protective gloves during operation.
Changing the brake fluid for an Q5 requires some patience, as I've done it myself several times. You'll need DOT4 brake fluid, a transparent hose, an oil catch bottle, and a wrench. Safety stands are crucial—after lifting the vehicle, you'll need to repeat the process for each wheel. A friend can help by pressing the brake pedal while you loosen the bleed screw. Start with the right rear wheel: one person presses the brake pedal until resistance is felt and holds it steady, while the other immediately loosens the bleed screw to let the old fluid and air bubbles flow out. Once new fluid starts coming out, tighten the screw. Repeat this process three to four times. Keep an eye on the fluid level in the reservoir and top up with new fluid as needed. After completing all wheels, pump the brake pedal several times to bleed any remaining air. Finally, always test the brakes before hitting the road.
