In my experience, you get what you pay for. I put cheap pads on my Ford Ranger and they were horrible. Didn't stop very well, pedal faded, brake dust was ridiculous.
After about a year I replaced them with some from napa that cost about $50 iirc and couldn't be happier. Much more stopping power, pedal stays solid and almost no brake dust.
