Stock caliper slide pins - where to get?
I think I need to put in some new all around, 8 pins & rubber seals, mine have 30k miles & the rear rubber is melting. Where do you guys get these? Rock? Got a part number? Any other fasteners I should replace while I am in the brakes?
The bolt that holds the pin takes such a low torque value, it hardly seems it would stretch much, but what do I know, that's why I ask.
Found ac delco, raybestos,wagner, dorman
Which is best?

The rubber is going to melt, no big deal. Same as piston boots. You can get replacement bolts at any parts store. But they're probably fine. Grease them whenever you get a chance.

Yeah, I gave up on the piston boots, but the slide pin rubber seems to hold up better. I just don't want any crap in there that prevents the caliper from moving easily, I do lube them ever pad chg.

I bought new guide pins, rubber boots, and bolts from Rockauto. I believe they have both AC Delco and Raybestos. I think that Rockauto also sells the rubber boots separately. There is probably no difference in the boots between '88 to '04 and may even be a common GM boot across lots of cars.
The important thing is to use a good guide pin grease and if you buy bolts at a hardware store (you can get the proper size and strength at Lowe's or Home Depot) make sure to use some Loctite Blue threadlocker on the threads. IIRC, the torque value on the guide pin bolts is only around 25 ft-lbs so you want them to be held in place.

Did you take a close look at the old vs new pins for wear, or just put them in?

This thread I started back in June lists the brake parts, part numbers, vendor, and prices for the upgrade. IIRC, the guide pin boots appeared to be the same for the C4 and C4 caliper. The bolts are the same and it's possible the guide pins are the same. You can use the Rockauto online catalog to search for brake parts for your car and then for a C5 to verify part numbers.

pull them out and clean them up, you should be able see see if they are bent or scored. mine looked good after years of track use so I never bothered to get new ones.
