I put front and rear brakes on my toyota rav my wife tell me she has to put more pressure to stop and the front pads smell like they are heating up I did put ceramic pads on front and back the brake pedal is not the same before I changed the pads, need more pressure to stop

Pads *and* rotors? They wear together, and if you only change one, it takes
a LONG time for them to wear to the same relative "flatness" as each other.

Did you "bed" them in before letting her drive? Usually consists of getting up
to 45-50 MPH, then braking semi-hard, enough to bring the car *almost* to a
stop in about 5 seconds. (Find a nice quiet backroad if you can. Try not to
do it in traffic or on the freeway). Repeat several times until they start to feel
normal enough to be safe. Try not to overheat them, but they will smell like hot
brakes while doing this. Take a few laps to let them cool down afterwards.

When I change my own brakes, even after doing the bed-in process,
sometimes it takes a week or so before they feel exactly like the did with
the old parts. Just takes time for the rough pads and rough rotors to
smoooooooth out and match each other.

Pads only? From the description I would say that you have a sticking
caliper and need to at least scuff or cut the rotors to allow the pads
to seat.

If you upgraded to ceramic pads from a softer material, it might require more pressure to stop. That's normal. Some smell might be normal too - initially. If you're worried about the caliper pistons being stuck, jack the wheels up and make sure the pads aren't binding. Give the brake pedal a nice firm push first.

Given how few pad manufacturers there are, the price and location you buy
brake pads from is completely meaningless in terms of performance.

What matters most (other than fitment) are the hot and cold coefficients.

What are the friction coefficients of the pads you put on the vehicle?
And what are the OEM hot/cold friction coefficients to compare against?

Every passenger vehicle brake pad sold in the United States
must (by law) say on the pads/package what the friction coefficients are.

The main rule is never buy a pad with a lower friction coefficient
than OEM where hot/cold friction is the fundamental decision metric.

1. You buy by fitment first and foremost (as it has to fit the calipers).
2. Then you buy by cold/hot friction coefficients (never lower than OEM).
3. After that, all the fluff can be considered (but you have no metrics).

The non-measureable situation-specific fluff is whether or not they put a
grain of sand in the mix so they could advertise it as "ceramic" or whether
or not they put an atom of copper in the mix so they could advertise it as
"metallic" or whether or not the epoxy will dust a black color or tan, etc.

NOTE: All brake pads dust (where do you think the pad goes?).
What matters is the color of the dust (and whether it sticks or blows off).

Same with noise.
All pads make noise - but you care about "loud noises" which is vibration
specific and very often fitment specific (e.g., springs & plates, etc.).

But if the pad has the wrong coefficient of friction for your needs, then
it's the wrong pad - so it's the first thing (after fitment) you look for.

If you don't know the answer - then you have no business discussing
anything else as it's like caring about the color of your girlfriend's hair
(which is something you think about well after the essentials are covered).
