Changing brake pads on 6 cyl. 93 Chevy Lumina?

Trying to change the back brakes (pads) on my 6 cyl. 93 Chevy Lumina - Having no problem with the bottom Bolt using a ratchet but the top bolt won%26#039;t budge! Can%26#039;t fit the ratchet in with the space I have so using a wrench with leverage bar and I don%26#039;t want to strip it. WD-40 won%26#039;t loosen it.......Any suggestions?





Thanks in advance ;o)|||If you are just changing the brake pads, you can get that top caliper bolt with a deep well socket. If you are removing the caliper bracket, you will need a T-60 Torx socket, and alot of strength. They use Lok-Tite on those threads from the factory, due to a TSB on 1988 to 1992 models%26#039; Torx bolt coming loose. When I worked in a shop, we would heat up that caliper bracket where the bolt goes through the steering knuckle, and put a 2 foot long pipe on the ratchet. You may also want to turn the wheel all the way out. That will give you more access to get the leverage with the long bar on the ratchet. Good luck.|||maybe you should get a mechanic for now, it might be rusty or something weird. perhaps getting a new bolt and try to cut that one with one of them hardcore machines... :?|||try tapping the caliper with a hammer while trying to loosen|||Torch is the next typical tool. Don%26#039;t catch anything on fire. After heating it up real hot put some ice on it.





All you are doing is causing it to expand and contract so things will break free... and they usualy do. Just be safe with the fire.|||Go to the Auto store and buy some PBlaster.|||yea try soaking the bolt with wd40 for a while keep spraying every so often good luck you dont want to strip or even brake the spoke which happened to me|||Don%26#039;t use WD-40, it%26#039;s a degreaser you need to keep that Hi-temperature grease around your brakes, but if you have some to replace it, it%26#039;s fine. Try getting a C-clamp and clamping down tight with one end on the back of the caliper and one end on the front of the brake pad, that usually does it for me.|||try heating the base of it with a torch





try not to melt the rubbers
