Luxgen 7 SUV (1st generation): Brake Fluid Replacement

Brake fluid is hygroscopic. Over time it absorbs moisture, its boiling point drops, and corrosion develops in the brake lines and the ABS unit. Brake fluid is usually replaced every 2 years, regardless of mileage. The exact system capacity and fluid specification for this model are not documented in publicly available service materials, so below is a general procedure that suits vehicles with ABS/ESP. Check the fluid class against the marking on the reservoir cap.

Difficulty: Medium Time: 1.5-2.5 hours Steps: 13 Tools: Jack and jack stands, lug wrench, clear hose for the bleeder fitting, clear container, open-end or box-end wrench for bleeder fittings (usually 8-10 mm), syringe or turkey baster for emptying the reservoir, rags, gloves, safety glasses. For bleeding on your own, a helper or a one-man brake bleeder kit is useful.

Part

  • 🔩 DOT 4 brake fluid (match the class to the reservoir cap and the owner's manual; do not use silicone-based DOT 5). You will need about 1 L (1.1 qt), and it is better to buy 1 L to have some extra

Step by step

13 steps
  1. Park the car on level ground, set the parking brake, and chock the wheels that stay on the ground. Shut off the engine and press the brake pedal several times with the ignition off to release the vacuum in the brake booster.
  2. Open the hood and wipe the reservoir cap and the area around it so dirt does not get inside. Open the cap and draw out the old fluid with a syringe down to a level just above the MIN mark. Never let the bottom of the reservoir become exposed, or air will get into the system.
  3. Top up with fresh fluid to the MAX mark. Throughout the whole procedure, watch the level and do not let it drop below MIN.
  4. Raise the car and remove the wheel you will start with. Bleeding goes from the wheel farthest from the master cylinder to the closest one. This is usually rear right, rear left, front right, front left. If your vehicle has a different circuit layout, follow the "farthest to closest" principle.
  5. Remove the protective cap from the bleeder fitting on the caliper and clean the fitting. Attach a tight-fitting clear hose and put the free end into a container with a small amount of fresh fluid so that air is not drawn back in.
  6. Your helper slowly presses the pedal several times and holds it down. While they do this, you open the bleeder about half a turn and the fluid flows out. Close the bleeder before your helper releases the pedal. Repeat until clean, light-colored fluid with no air bubbles comes out of the hose. Usually 150-300 mL (5-10 oz) is used per wheel.
  7. Remember to top up the reservoir after every 2-3 cycles. Tighten the bleeder with moderate force. It is thin and easily snaps off, so it is best to take the exact torque from the manufacturer's specifications. As a guideline, the value for such fittings is small, around 7-12 N·m (5-9 lb-ft). Put the cap back on.
  8. Repeat steps 5-7 on the remaining wheels in the order given. If a bleeder is seized, do not apply a lot of force. First treat it with penetrating oil and let it sit.
  9. Install the wheels and tighten the lug bolts in a criss-cross pattern. Check the lug bolt torque for this model in the manufacturer's specifications, and do not tighten it by feel.
  10. Set the fluid level to the MAX mark and close the cap. Press the pedal several times: it should feel firm, with a short working travel and no sinking.
  11. Turn the ignition on and start the engine. Check that there are no ABS/ESP or brake system warnings on the instrument panel. Check the bleeders and connections for leaks.
  12. Take a test drive at low speed in a safe area. Test the brakes several times, including a light ABS activation on a slippery surface if you have the opportunity.
  13. Dispose of the old fluid at a collection point. Do not pour it down the drain or onto the ground.

Common mistakes and warnings

  • The brake system is critical to your safety. If the pedal feels soft or sinks, bubbles remain in the hose, or the ABS indicator is on, do not drive on the road and contact a repair shop. Brake fluid damages paint, so wash off any drops with water right away. Do not mix different fluid types (DOT 4 and DOT 5), and do not use fluid from a container that has been opened before. If there is a lot of air in the system, or air has entered the ABS unit because of a level mistake, bleeding with diagnostic equipment may be required, and that is a job for a repair shop.
