How many kilometers should the brake fluid be replaced for the Regal?
1 Answers
The brake fluid replacement interval for the Buick Regal is 30,000 kilometers, using Mobil brand DOT4 fluid. Below are the steps for replacing the brake fluid in the Buick Regal: 1. First, prepare an oil extraction container for the brake fluid. If possible, avoid using the method of pressing the brake pedal, as this makes it difficult to completely drain the old fluid. 2. Extract the old brake fluid from the reservoir in the engine compartment, which takes about 10 seconds. 3. Then, use the extraction container again to remove residual brake fluid and air from the lines. 4. Connect the hose of the extraction container to the bleeder valve of the wheel cylinder. Once connected, begin extracting the remaining brake fluid. 5. While extracting the brake fluid, have another person continuously add new brake fluid at the filler port. Under pressure, the new fluid will push out the old fluid, and this also prevents air from increasing in the lines due to lack of fluid. 6. The extraction process typically takes about 8-10 minutes. After completion, add brake fluid to the appropriate level on the dipstick, close the cap, and start the engine to test the brake performance. Press the pedal multiple times consecutively; if it feels soft, continue bleeding the air.
