not sure about 2004 Pontiac, but i have 1995 Nissan Maxima that i couldn't get rear brake caliper pistons to go in, found out they actually are threaded inside caliper so that piston has to be "screwed" in, can't just push it in with c-clamp. there's a tool you can buy to do it, but i made one myself with a 7/8 socket that i grinded down to have four points that matched up with the notches on the piston head. even then, it was very difficult, it doesn't screw in easily. if your piston head is flat faced and has notches on it (3,6,9, & 12 o'clock positions on mine), it's probably that kind. good luck.
I have an '04 Vibe. Easiest method is to buy a brake pad spreader from an auto parts store. They are usually run $6-10. Its just a long screw with a twist knob at the end and two metal plates. You fit the plates into your brake caliper and turn the knob until the piston is pushed back in.
screw it in turn the piston clockwise and screw it in , only for rear brakes
I have a 2004 TSX and learned the hard way how to change the rear brakes and had to buy a rebuilt caliper for my mistake. Most brake calipers compress with a simple C-clamp to make room for the larger/newer brake pads. The rear brakes on a TSX are different and you'll notice they have a couple of grooves on the caliper piston. They make a tool that is sold at AutoZone that allows you to compress the caliper piston by rotating it clockwise back into the piston. (It looks like a metal cube with metal prongs sticking out) I also recommend using brake grease on the exposed caliper piston boot prior to compressing it as this will allow the piston to rotate without damaging the boot. Don't forget to bleed the brakes afterward since rotating the piston will likely allow some air into the brake caliper.
Rewind it with a piston rewind tool or, at a pinch, use needle nose pliers.
take the tire off, remove the caliper, remove and replace brake pads, compress piston, slide caliper over the roter, tighten up the bolts on the back of the caliper, do one side at a time, open up the master cylinder before messing with it, its pretty easy.
You need to buy a c clamp one that can open atleast 6 inches take the old brake pad place it back in the way it was in there then there should be a screw on the caliper losen the screw just a little bit then put the c clamp over the brake caliper one end of the c clamp on the old brake pad the other end on the back of the caliper then tight c clamp till the caliper piston is flush with the caliper note when you thighten the c clamp brake fluid will come out of the screw that you losend so after you do all that spary some brake cleaner on your caliper rotor then put your new brake pads on add some brake fluid if needed the your ready to go
The brake pads on a 2004 Dodge Ram 2500 4x4 are replaced by removing the wheels, unbolting the calipers, and taking out the brake pads. The caliper piston must be pressed back in before new pads are installed.
No. 6 point 12mm socket. (Cant be deep well socket though, not enough clearance for that)
brake caliper bushings are the rubber mounts that sit inside the caliper bolt holes. They help guide the bolts when bolting the caliper up to the caliper bracket.
Remove wheels Loosen 2 Caliper mounting bolts Remove only one to allow caliper to swing away from rotor Remove rotor Remove outer brake pad Use "C" Clamp to retract piston into caliper body Remove inner pad Replace inner and outer brake pads Replace rotor Resecure brake caliper BE SURE TO PUMP BRAKE PEDAL PRIOR TO MOVING VEHICLE TO SET PADS AGAINST ROTOR
No, the 2004 Durango is a completely different brake system.
Hose?
---- You have to turn it (caliper piston) as you are depressing the piston back into the caliper. You can't just "jam" it in. I used a caliper tool (for depressing the caliper) and turned the piston with large jaw pliers. This gives both inward pressure and the turning motion. I turned it clockwise and that seemed to work. There is a special tool you can buy to turn the piston as you push it back into the body of the caliper but if you work carefully and you are VERY aware of the rubber boot (don't rip it) then pliers are ok (don't tell the Ford dealer). Cover the pliers with something so you don't scratch/ruin the piston. The front brakes are just a standard push - don't need to turn them. Why do the back brakes work this way? Has to do with the parking brake. If you look you can see that it is attached to the caliper on the rear.
