I have installed all new brakes for my 3000GT NA FWD 1995 ATX with no ABS.

Why do I need the rubber guide pin bushing that fits on the end of the guide pin (slider bolt)? Can I remove it and install the slider bolt without it being there?

There is only 1 bushing of this type on the 1 guide pin vs the other "lock pin" which doesn't have a bushing or a groove for one like the "lock pin" does. I figure this was put there for a reason, but it seems too damn tight for the slider action to even work right anyway. HELP ! I have to get this done fast.

I had previously put the wrong slider bolt grease in the bores of the caliper bracket and I'm redoing the slider bolts with proper grease as a result. I'm wondering if the suspension grease I'd used before "swelled" the rubber guide pin bushing while it was in there making it too big for the slider bolt bore thus causing it to lock up pretty well. I can apply FULL force to get the bolt in there and it will not budge at all. This made me think - why do I even need this bushing at all? It seems like the setup would work fine without it.

May be gummed up and preventing good slide action. Hopefully you have thorougly cleaned everything. Spray some brake clean into that sticlky hole for the pin and get it clean in there. All the moving parts when clean should be coated wit high temp caliper grease

That bushing may seem tight because it may be trying to compress the grease already in there, not sure with out having it my hands. I wouldn't remove it, but it should slide. I doubt the swelling of from the grease. If in doubt, replace it, haste makes waste.

Yes everything is squeaky clean, but my question is WHY DO I NEED THIS BUSHING AT ALL?

It would make life much simpler to remove it, but I'm hesitant to cause it was put there as part of the design and there is a special groove on the guide pin for it to slide onto it at the end. Does this bushing cause/create a suction which brings the brakes back apart?

I can't speak for the engineers on this one, my guess is they were able to save a little metal aka weight for fuel conomy purposes. The bushing is probably keeping the pin centered.
