i will try to make this long story short, but i spent the weekend installing bilstiens, hypercoils, slotted n drilled rotors, and brake pads. everything was sailing along, easy peasy japaneasy, until the front calipers. on both front caliper brackets, one of the two (not sure of actual part name) floating pins that the smaller 2 of the 4 bolts threads into were seized up. my brakes had been steadily getting worse and when i put my new C6 wheels on last weekend i noticed the right rear had a crack all the way across. but i guess this was my real problem. we first noticed the problem after putting the driver side back together and the rotor would not turn without a prybar. after discovering the problem we soaked it down with an anti seize spray and went to the passenger side. it too had one completely seized and the other just barely moved. well after much effort we got the passenger side all freed up, used some sand paper to clean up the corosion and rust put some grease in it and put it back on. the driver side on the other hand would not give. ended up breaking the pin off inside the bracket. drove all over town trying to find a caliper bracket to no avail. ended up buying 2 kits, one with the pins and the other with the grommet/boots. went back home and drilled a hole from the other end and used a punch to drive it out (had to use 4lb sledge). cleaned it out, used a tap kit to thread the hole we drilled and ran a bolt into it, and put it back together. everything looks good and works great. apparently, i haven't had decent brakes the whole time i have had the car(since may of 07) because there is a HUGE improvement!! i am going to have pics in a couple of days of all this taking place on my links in my sig. but i guess my real question is: is this a commond problem? should i look to aftermarket calipers and brackets? i guess this problem has been putting constant pressure on my pads and rotors at all times. hell, i think my gas mileage improved on the way from pops house to mine!

both front rotors were heat checked and warped and like i said the right rear was cracked. left rear seemed to be fine. ok, i will end this now

so much for keeping it short eh?

any ideas? suggestions?
thanks
