    Hey Guys,

    So this is what happened:

    Brakes worked fine, i drove the truck, and parked it outside. It was cold i'd say about - 15 outside.

    Started the truck in the morning, and brake's would apply but only being pushed in all the way.

    Weird thing, if i put truck in park, and pump the pedal, things firm up. But as soon as i start driving again, it becomes all loose and saggy.

    No leaks in brake fluid anywhere to be found after 50 km of double pumping lol.

    It was a Sunday no one was opened, convinced a neighborhood mechanic to just have a look, he asked what was wrong. Told him my story, he said the master cylinder is probably gone, since there are no leaks in the fluid, no lines have burst etc.

    He said if i really wanted to stay on the road, i should double pump. And keep my distance. But things can go South real fast if i don't replace the master cylinder.

    I have an 2003 Tacoma Double Cab 3.4 Auto Trans.

    I am thinking of getting the brakes bled before i opt for an expensive cylinder swap.

    Any insight on my problem guys ?

    Pull of the vac line from the brake booster. If there is ANY fluid in there, your master is leaking into the booster.
