2000 Toyota Revo brake dragging

I'm driving a Toyota Revo automatic.
The brakes are dragging, especially when I'm making a right turn.
Then the brake will release when I turn to the left or push hard on the brake pedal.
Sometimes it releases after one push, but usually it require a few hard pushes.
When the brake locks while on a slope, the car will roll backwards
and I have to use the handbrake to prevent the car from rolling all the way down.

Your question is a little confusing.
You mentioned that when the brakes locks, it rolls backwards on a slope? I don't understand how that can occur.

Do you mean the pedal is stiff and brakes won't work? Can you elaborate on the problem?

Tnks for answering my question.

The car is an automatic.
If im on a slope, say a car park entrance,
the car will roll backwards if I dont pull on the hand brake.
If I step on the gas, I hv to really step down on the gas to go forward.
When I step on the brake, it stops, but if I release the brake, it will roll back.
This happens only when the brake locks, if not, everything drives normally.

Also, the brake is never stiff.

Vehicle rolling backwards can either mean the idling speed is too low or the transmission is not working correctly.

Low idling speed can result in loss of vacuum for the brake booster and that can affect braking efficiency.

I do not know if my guess of the problem is correct as I don't fully your question and explanation of the problem.

Tnx for the reply.

Let's just forget the slope problem first.

Please give me your recommendation for the dragging problem.
"The brakes are dragging, especially when I'm making a right turn.
Then the brake will release when I turn to the left or push hard on the brake pedal.
Sometimes it releases after one push, but usually it require a few hard pushes. "

My mechanic is recommending replacing the brake booster and caliper.
One at a time. To see which works.
Both are expensive.
Which do you recommend I replace first.
TIA.
