Hello, I'm Danny.

Here is the information you requested. Here are 2 tutorials showing how to replace the master cylinder and properly bleed the system after replacement:

https://www.2carpros.com/articles/how-to-replace-a-brake-master-cylinder

https://www.2carpros.com/articles/how-to-bleed-or-flush-a-car-brake-system

It is suggested to bench bleed your new master cylinder before installation. Here is a YouTube video from our site showing how to do so:

I've attached picture steps below on how to remove and replace the master cylinder on your car. Hope this helps and thanks for using 2CarPros.

Hi,

Replacing the brake master cylinder isn't too hard of a job. In most cases, the master cylinder will last a long time. However, I recommend getting a lifetime replacement part in the event it fails again.

First, here is a link that shows in general how it's done. You can use this as a guide:

https://www.2carpros.com/articles/how-to-replace-a-brake-master-cylinder

Here are the directions specific to your vehicle. The attached pics correlate with these directions.

REMOVAL

NOTICE: The structure of the master cylinder allows the piston to pop out, so observe the following:

(a) for TMC made:
(1) The master cylinder requires careful handling. Do not allow the master cylinder to receive any impact, such as from being dropped. Do not reuse a master cylinder that has been dropped.
(2) Do not scratch or damage the circumference of the piston. For the seal to function correctly, all sliding surfaces must not have any damage.
(3) Do not pull out the master cylinder piston.
(4) Make sure to release the vacuum from the brake booster (by removing a vacuum hose, etc.) before removing the master cylinder from the brake booster.
(5) When installing the master cylinder, remove the protectors for the piston and the discharge port.
(6) Apply the supplied grease to the outer diameter of the piston and the inner diameter of the brake booster.
(b) for TMMK made:
(1) Do not hold the master cylinder by the piston. (Hold the master cylinder by its body or its reservoir while transporting it.)
(2) Do not pull out the master cylinder piston.
(3) Do not strike or pinch the master cylinder piston, and do not cause any damage to the master cylinder piston by any other means.
(4) Make sure to release the vacuum from the brake booster before removing the master cylinder from the brake booster.
(5) When installing the master cylinder to the brake booster, or when removing the master cylinder from the brake booster, make sure that the master cylinder is kept horizontal or its tip faces downward (the piston faces upward) to prevent the master cylinder piston from falling off.
(6) Do not allow any foreign objects to contaminate the master cylinder piston. If a foreign object gets on the piston, remove it by using a shop rag or a piece of cloth and then apply an even layer of lithium soap based glycol grease around the circumference (sliding part) of the piston
(7) Do not use any other type of grease.

Hi MARKRAPPAPORT,

We can help you with this information.
when you put it in park the vehicle should engage and not move.
more information is required to help, when diving and applying the brakes do they feel spongy and does the brake pedal when applying brakes moves down, does your foot emergency brake work?

https://www.2carpros.com/articles/brake-system-warning-light-on

Let us know what happens and please upload pictures or videos of the problem.
Cheers, Nick

I have had the master cylinder replaced 3 times within 3 weeks. The brakes have been bled. The pedal now goes almost to floor. I am being told this is normal. However, this was not how the pedal was prior to the replacement. Also, there is leaking from each of the new master cylinders. What needs to done to correct the pedal and the leaking?

You can't have leakage and expect the pedal to remain high and firm, and you're right, a sinking or low pedal is definitely not normal. Where is that leakage occurring from? Do you have power brakes? If you do, and the leakage is from the rear of the master cylinder, the fluid would go into the booster and there's a real good chance you wouldn't see it. That implies it's leaking from one of the ports. The first suspect would be the line nut is loose or the flare on the end of the steel line is cracked.
