    i have a 2008 toyota tundra that the brakes have been acting up. the peddle is real soft and goes down to the floor and will start pulsating with the abs. I changed the master cylinder 130.00 bucks later and its still doing the same thing .
    Anybody have any thoughts on this?

    Did you bleed the master before you installed it? and you may have to have the abs module bled and that may require a scan tool that has abs capabilities.

    i did bleed the master cylinder before installation.
    i was having the same issue before i installed the master cylinder thinking that was the problem.

    It may have to be power bled.

    can anyone help me on locating the brake booster relay on my 2008 toyota tundra?
    I found two relays that are marked brake1 and brake2 but nothing with brake booster on it.
