Where do you Bleed brake fluid on a Lexus LS400?
Brakes should be bled starting with the wheel that’s furthest from the master cylinder and then working in towards the cylinder. Now you would think that would be the rear passenger wheel, it’s not! Taking a look at the repair manual shows the routing of the brake lines.
Why is my brake fluid leaking from the master cylinder?
If you have to exert extra pressure on the brake pedal then, there are chances that the master cylinder has the air inside them, which is further causing leakage of fluid. Or, if the brake pedal is depressing itself then, this means that the heated brake fluid is not able to expand.
Why does my brake pedal get soft when the master cylinder wears out?
The rubber seal on the master cylinder wears out with the time. And, if these seals are not replaced timely, they may contaminate the brake fluid. Thus, causing the pedal to get soft and doughy or slowly sinking to the floor.
What happens when you press the brake pedal?
Contrarily, the master cylinder found in every modern car today begins to operate when the brake pedal is pressed. It pushes the fluid from the reservoirs to the lines in the braking system, which exerts pressure on the brakes. And finally, this pressure slows down the car or causes it to halt.

How does the brake master cylinder work in a Mustang?
The brake master cylinder supplies hydraulic pressure to your brake calipers and wheel cylinders. It also includes a brake fluid reservoir that can be filled if you notice you have a leak. As the brake pedal is pressed down, the master cylinder plunger pressurizes the brake lines to operate the calipers or wheel cylinders.
What happens when your brake pedal goes to the floor?
If your brake pedal goes to the floor you have a problem. If it were an older car I might suspect the brake master cylinder or even a leaking system, of course a puddle of fluid under the car would support a leaky system. Because it’s not an old car I would bleed the system again, properly.
