adviser told me that the brake master was leaking

Hi,

The brake master cylinder isn't too hard to replace. It will require a few different steps, but nothing too hard.

To get you started, here is a link that explains how one is replaced in general. You can use this as a guide.

Next, here is a video showing how to bench bleed a new master cylinder. You will need to do this before installing it.

Now, if you look at the attachments below, I included the directions specific to your vehicle for bench bleeding and removal and replacement. The pics correlate with the directions.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
