My brakes were fine, i tryed to stop and the brakes felt hard. After a few minuetes was fine, what can it be.
Didn't Toyota have a recall on some models for brakes? Check the recall website.
I get the impression there is a problem with the brake servo as in it works one minute, brakes are good, then there is a lack of servo assistance, brakes are hard.
Locate the brake servo behind the brake master cylinder. See the hose running to the inlet manifold? If this has any wear marks, chaffing marks, it could be leaking vacuum, (the servo is vacuum not pressure), and need replacing.
It has to be the correct type of hose to resist collapse when the vacuum is created otherwise you would have no brakes at all and the pedal would be hard all the time. Check the manifold connections at the same time. There is a chance the hose is partially blocked or damaged internally and only replacement with a new piece will do.
Don't drive it until you have eliminated the problem, it could be your life.

get it inspected, You may just have one sticking caliper that need replacement. the brake pads will be pretty worn on that wheel so you may needs pads also.

If the pads are not glazed, I would check the function of the brake booster.
Is the ABS warning light on ?

If the ABS system were the problem, the ABS warning light should come on.
So I would say the problem is with the vac booster. The booster is between the pedal and the master cylinder. It uses vac to boost the pressure applied to the master cylinder by your foot.
You may have to leave the vehicle with a mechanic to drive until the problem occurs.
