Put new pads up front and it seemed to brake really good at first. Then I noticed (after it had sat for a few weeks) it was pulling under heavy braking and I noticed the outside on both rotors had rust on about 50% of the surface area.

Today I took the calipers off and re-greased the sliders, as they were extremely hard to get out and I thought that was my only problem. But its still about the same.

Any ideas?

Stock brakes and worked great before I replaced the pads, but I had owned the car for about 5 years and never changed the pads and knew they were about at the end of their life.

Are those long skinny roll pins that hold the pads in place OK? It sound like one may be binding.

1. use must use brake grease to lube sliders.
Normal grease will swell the "o-rings" and need to replace them.

Is normal that slider need some force but really stuck then big problems.

Roll pin?

Its on both sides, I suppose they both could be binding. Even though its not the first brake job I did on a Fiero, I still feel like its user error somewhere.

That's just on the 88 I guess, and you are probably looking at an earlier model.

Experienced this once, the pads have little alignment buttons on the back that are "supposed" to engage the caliper body for proper alignment. Ultimately the pad was not seating flush and was instead rocking on the buttons. Only the inner 50% of the pad would make contact leaving a nice rust around the outer edge under the pad. Perhaps the buttons were a little big, possibly not 100% perfect from China or the years of driving caused the little recessed area to be full. Solution was a quick run across the grinder and remove some/all of the alignment buttons for a flush fit. Its an 88' so it has the roll pins working for you.
