Sorry it took so long.
1.Disconnect brake fluid sensor electrical connector from master cylinder reservoir.
2.Position a drain pan under the master cylinder.
3.On models with separately mounted reservoir, disconnect reservoir hoses from the master cylinder.
4.On all models, use a suitable wrench to disconnect brake lines from the master cylinder. Plug all lines and fittings.
5.Remove master cylinder-to-brake booster attaching nuts.
6.Pull master cylinder outward and away from brake booster.
7.Reverse procedure to install noting the following:
A.Be sure you bench bleed master cylinder per-instructions that come with it before installing
After installing master cylinder bleed the system as follows.
1.Ensure master cylinder reservoir is full. Add suitable brake fluid as needed, and securely reinstall the master cylinder cap.
2.Raise and support vehicle.
3.Position a drain pan under the wheel being bled.
4.Have an assistant depress the brake pedal with a slow even pressure and hold it. Do not depress brake pedal fully to the end of the master cylinder stroke. This may cause damage to the master cylinder.
5.Using a suitable wrench, open the bleeder valve one full turn. Watch for air bubbles in the fluid, and listen for air escaping from the system.
6.With the brake pedal still depressed, close the bleeder valve.
7.Have the assistant pump the brake pedal several times. Do not depress brake pedal fully to the end of the master cylinder stroke, this may cause damage to the master cylinder.
8.Repeat steps 4 through 7 until all air is removed from the hydraulic system. While bleeding the system, recheck brake fluid supply in the master cylinder often so as not to allow the master cylinder to run dry.
9.Upon completion of hydraulic system bleeding, proceed as follows:
A.Ensure the master cylinder reservoir is full. Add suitable brake fluid as needed, and securely reinstall the master cylinder cap.
B.Lower the vehicle. Ensure brake pedal is firm and braking operation is proper.
