so i went to replace front pads with lower dust pads. upon reinstalling the calipers, i realized that the lower caliper slide on both front brackets were seized. when i tried to extract the old slides, they just broke.
anyway.... every parts store sells rear brackets separate, but only napa had front brackets. they ONLY came as loaded calipers with brackets.
long story short, i did both calipers up front and brackets.
All f-bodies experience this, thats why the rotors warp. When I changed my pads and rotors all the slides were dry, and stuck. I bought all new OEM pins from the dealer and used some anti seize on them and that took care of it.
my Sten had a similar issue with the rear calipers.. common on all GM trucks with rear disc... but the slides on the T/A were totally fused... not able to be freed up.
rather than go thru the effort to drill... i went with the new brackets, complete with new slides and boots.... for the money, it seemed like the best option.... for a total of $130 i got new calipers, brackets & slides for the front.. they even came with new pads, which i did not use.
how likely is it that my rears will suffer the same fate?
i used the white purpose lithium grease! that works perfect since it waters out when it sees heat so the whole pin is lubercated inside the boot, and i used aircraft c5 high temp copper antiseize on all bolts and pad sliding clips
153,000+ miles on the orginal calipers..no problems with them...I always use the correct lube when I do brake jobs(about every 50K).
