    Hello everyone. I’m trying to fix my brake problems on my own and I have determined that my loss of brake fluid is because the master cylinder is leaking into the booster. I thought I could just order a new master cylinder but my local auto parts store is having trouble finding the right one. I’m hoping one of you gentlemen would be so kind to look at this photo and tell me what I am looking at. The master cylinder looks like it’s comprised of two separate components, do you suppose this is going to come as one large assembly or am I only Replacing one Component or the other?
    Thank you

    I picked up a new master cylinder for my 2003 sequoia at Napa. From what I remember I could get one from Toyota and it sounded like it came with just the lower section and not the reservoir on top. I went with the Napa brand one and it works great, It was much less expensive. I want to say around $120. You might have to replace the booster if brake fluid leaked into it. Maybe someone else will have some more info for you.

    Thank you for the reply. I should have been more specific. The master cylinder itself looks like it’s split. I can see a seam and gasket with a couple bolts holding the front and back portion together.

    Interesting. Mine didn’t have that little piece in between the booster and the master cylinder that I remember. Pretty sure my brake lines went into the side of the front piece. That must be something they changed through the years.
