Remove the caliper, by removing the two holding bolts, then use a old brake pad against the pistons and a c clamp and push piston all the way in, next is to clean and lube pad mounting surface and the caliper slide pin, then install new pads on bracket then caliper and tighten caliper bolts, heres a diagram to help you,
2005 grand prix. the rear brakes changed pads now i cant get the caliper to go back down ive tried several differnt c clamps.
After removal of the tire. Unbolt caliper and pull off of the rotor assembly. Remove retainers that hold pads in and replace in reverse order. You may have to have rotors serviced or replaced if worn, warped or gouged.
SOURCE: do i need a special tool to change rear disc
no special tools needed,same as doing the fronts

a quick test is to disconnect the sensor connector hook up and ohm meter to the sensor connector on the hub side not the engine side and spin the hub if the resistance rises and falls you're most likely ok if the resistance reads 0 or infinite you have found the bad sensor..this won't always be the case but it's a good start in the right direction
SOURCE: how do I change brake pads on a 2006 Pontiac Grand
Yes, You can buy a manual at your lacal parts store.
However, It's not that hard. But , you didn't say if you
need to change the front or rear pads?
I'll assume your refering to the front.
1st You'll need to jack up the car if you only have one
Jack then, pick the side you are too start say left front.
Jack the car up like chainging a tire BUT, Jack the car
up but, leave the tire touching the ground with, some weight
still on the tire with a lug rench turn the lug nuts JUST enought
to loosin the nut DO NOT take the nut off, maybe 1/4 " only.
Do the same on the others. Now, Jack up the car until the tire
is off the ground. NOW, Put a Jack Stand under the car never
NOT use a stand. Remove the nuts and tire.
Turn the wheel to the right it will give you more room to work.
You'll need to remove the caliper that holds the pads on.
There are two screws that hold the caliper on. I believe,
there 13mm remove the screws (Take them all the way OUT)
Remove, The caliper the pads, will stay in the holder.
Remove, the pads you may need a screw driver to get the
pads out.There are two pads that have a scencer on them
one for each side PUT that pad on the inside holder.( sencer down)
NOW rember you need, too make room for te new pads.
You need a c- clamp to push the piston BACK into the
bottom of the caliper. Be sure the piston is at the bottom of the caliper
or the caliper will NOT fit back on. Install the new pads into the holder.
.Then, put the caliper back on to it's mount over the new pads.
Put the two caliper bolts back and, your done.
Reverse, the infromation from the top.

SOURCE: 2005 pontiac grand prix, code p0641 came on. What
DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the
following sensors:
The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage
is higher or lower than required, DTC P0641 will set.
Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the
5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when
the diagnostic runs and fails. The control module records the operating conditions at the time the
diagnostic fails. The control module stores this information in the
Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3
consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and
passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures
are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.
Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.
Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.

On rear brake shoes there are two different size shoes..one small and one big (PAD).
The SMALL pad goes towards the front of the vehicle. The BIG pad goes towards the back of the vehicle. This should help you...
Remove wheel, remove the two bolts in the calipers, pull up calipers,
remove pads compress caliper piston with a c-clamp, be sure to have the brake fluid cap off the reservoir under the hood. pull the rotor off and put the new one on. - replace pads and reverse the order.
