How do you install a master cylinder in a Lexus 400?

To install a master cylinder in a Lexus 400, first, disconnect the negative battery terminal and remove any necessary components to access the master cylinder, such as the brake booster or air intake. Then, detach the brake lines from the old master cylinder, ensuring to catch any fluid in a container. Install the new master cylinder by aligning it with the mounting points, securing it with bolts, and reconnecting the brake lines. Finally, refill the brake fluid reservoir and bleed the brake system to remove any air.
