Re: Install new pads and rotors on pontiac montana, now...
Remove the wheels and make sure the inside pad is in place with the pressure tabs that are mounted on pads, also make sure you have both caliber bolts in correct holes and tightened

Could be loose caliper (unlikely but worth checking), bad pads (had them fall apart on me before when brand new), improper line bleeding (air bubbles in brake line), dirt on the rotor (brake cleaner will fix that. Remove tire and caliper, thoroughly spray down rotor, caliper and pads, let it completely dry and put back together). If none of those are the problem you may want to take it in for a brake system check, many places do that for free or cheap.
To remove the brake rotor, you must first remove the brake pads and caliper. There are two bolts that hold the brake caliper in place. Remove the two bolts and tie the caliper up out of the way. Be careful not to break the brake line connected to the back of caliper. Once the caliper is removed, simply slide the rotor off. To install a new rotor, simply slide rotor over studs and replace the caliper with new brake pads. It is as simple as that.
jack the vehicle up remove the wheel
remove the brake caliper bottom bolt 15mm. lift the caliper up and slide the caliper pin out
remove the caliper housing bracket 2 - 15mm. bolts
remove the brake rotor
remove the drive axle nut 1 5/16
the remove the hub bearing bolts 3- 13mm. they are in behind (best to use a 13mm flex socket)
disconnect the ABS harness
use a hammer and hit the hub bearing flage (it maybe corroded )
now the hub bearing is out clean the steering knuckle with sandpaper to remove corrosion
install the hub bearing (make sure the ABS harness is in the right position)
and reassemble
hope this helps
no that is only the older rear calipers on gm and others. the fronts do not have that style caliper and sound like the calipers are frozen and may be way your changing the pads. try opening the bleeder screw and then compressing them if they go then you need need brake hoses and if not you need calipers. god luck man
you will need a 15mm wrench, a pad spreder, and high temp greese
1 remove the lower caliper bolt
2 lift the caliper uppward
3 remove the inner and outer pad
4 depress the caliper
5 lube upper and lower sides of the new pads and rear of pad (this will preent squeeks)
6 reverse procedure
remember pump brakes at least 10 times before test driving have fun and good luck
remove the BOTTOM 15mm caliper bolt lift the caliper up and slide off
then remover the 2 15mm bolts holding the caliper housing on
remove the brake rotor (you may have to hit it with a hamer to break it free
depending on the brake pads you got some come with new sliders
remove the sliders clean the rust build up then install new sliders
lube the sliders install the pads
install new rotor
install the caliper housing with the 2 15mm bolts
install the caliper and lube both caliper pins with silicone lube
install wheels
PUMP THE BRAKE PEDAL TILL IT GETS HARD WITHOUT ENGINE RUNNING
You know this is hard to believe. Brake pads should go at least 40,000 even on the front. Calipers should last about 10 to 12 years. That's my record for 46 years running.I wish I had the vehicle and time to review this with you. Start from 05 and discribe every brake issues and EXACTLY what was done and why/
remove the keeper on the lug bolts, heat with torch and spray with cold water, turn all the way one way and beat with rubber hammer, keep rotating and hitting with hammer, it will come off keep hitting it.
1. Have the caliper checked if the retaining bolts are fully tightened and all shims and pins are properly installed. 2. Was your rotors resurfaced??If not, The new pads are flat(new), and the rotor might be uneven causing the pads to vibrate. 3. If they aren't the rotors, inspect the CV shafts for tightening, or damage. Hopefully this helps
