Default Are new brake pads supposed to suck at first?

This has happened in the past..and also last night when I installed new brake pads.
They work fine under normal driving..but get a little hot on them and they get real mushy and smell awful! My friend said it normal for a couple days until they break in???

They are VGX pads.

I'm familiar with VGX pads. We put some on our 97 prelude along with some new brembo disks. After a few easy break in drives, we gave them a good testing- they worked great, no smell, no mush. This was during a NC summer.
Did you have your rotors turned?
Are you sure nothing is getting on your rotors (ball joint or CV joint grease? brake fluid?) or that your rotors are not really dirty?
Maybe the problem is elsewhere in the system. You may want to throw the old pads back on and see what happens.
Good luck amigo !

Did you bed them in? All new pads save for Mintex will need to be heated substantially to let them outgas, and then they'll work much better. All pads need to be bedded to the rotors properly in order to work properly.

When I first put on my Carbotech Panthers, I had a little bit of a metal on metal scraping feel to them. But that seemed normal until they were bedded in. But that went away after driving around for a while. As for the mushiness, I didn't feel any mushiness with brand new brake pads. They grabbed hard even on day1 so I don't know what the mushy feeling is. I didn't even resurface the rotors or clean them when I did the install. I did bleed the brakes that day though. Maybe you need to bleed the brake fluid too?

I dont see why I would need to bleed the brakes...I didnt open up the system so why would air get in there just from changing the pads?

You should ALWAYS bleed your brakes when you change brake pads. The reason for this is that, even though you have not opened up the master reservoir, you are pushing back the pistons to their static position, which may in some cases cavitate the fluid inside the caliper. Also, if you have been on the track or have been driving hard, it is possibly that you have degraded the potential performance of the fluid near the caliper/piston from heat generated by hard braking.

If you track you vehicle, it is necessary, in order to maintain optimal brake system performance, to bleed your brakes before and after EVERY event.

Keep in mind that racing brake fluids are much more hydroscopic than your typical brake fluid, and thus will absorb moisture much more readily from the environment. Even though your brake system is a closed hydraulic system, it is still possible for moisture to work its way into the system.
