I was wondering if there were different brake pad sizes and what type of brake pads do you recommend for a daily commuter?
Do you
have the same problem?
Yes
No

There can be different sizes for one car model, but not that you can interchange them. There can be a standard brake system or a heavy-duty brake system. The replacement pads must match what came on the vehicle.

Manufacturers spend a real lot of time on research and development to produce a brake system that is balanced front-to-rear. One of the variables in those calculations is "coefficient of friction", meaning how well the linings grab the friction surface. They also look at how that changes with changes in temperature of the parts. When any manufacturer makes replacement pads or shoes, those variables have to be the same to maintain balanced braking. That means the cheapest pads will do the same job as the most expensive pads. In some cases the linings could be sized a little differently to offset different friction characteristics, but they will fit and mount the same as the original pads.

When comparing prices, why does one can of corn cost more from one company than it does from a different company? Quality is not something that is compromised when it could land a company in a lawsuit, so that shouldn't be a worry here. With more expensive pads, you might have anti-rattle clips included. With the less-expensive pads you may have to use old hardware over. More expensive pads might have a longer warranty period or might come with anti-squeal devices, (which usually don't work). Less-expensive pads might wear out faster, but until they do, they should perform just like the original pads did.
