stubby 18mm wrench and a hammer
Remove lower caliper slide bolt (12 mm) Remove brake hose line retainer bolt directly bottom of spring mount. Use large c clamp to collapse (retract) piston into caliper. Pull up on lower caliper slide rotating on upper slide when free of disc push back on upper slide. you should be holding caliper attached only by hose now Good luck.
This is how you will replace the front brakes on a 2000 Saturn Sc first you will jack the car up with jack stands. You will then remove the front wheels, next remove the upper caliper to mount bolt only. Then you will pivot the caliper downward to access the pads, you will remove the old pads and install the new pads. You will use a 'C' clamp and a old pad to bottom the caliper piston and you will pivot the caliper back into place and re-install the bolt.
Both the upper and lower caliper bolts must have the rubber boots on them. Otherwise, dirt and moisture will get in around the bolts and cause them to stick in the caliper mounts.
Lift the front end, Take the wheels off, open the bleeder screw while compressing the caliper with a c-clamp, close the bleeder screw, undo the caliper bolts, remove the caliper and set it on top of the upper control arm, remove the old pads, remove the caliper bracket bolts, remove the caliper bracket, remove the rotor, clean and lubricate all metal-to-metal contact surfaces, machine the rotors to specification, install in reverse order :-)
remove tire, remove upper bolt from caliper, secure caliper to avoid lines to get kinked, remove very carefully old pads, to avoid damaged the sensor wire, with a C clamp compress the caliper and install new pad, now you can put the caliper back in the old position, screw the bolt, put the tire back on, and that is all.
If it is the front ones, remove the wheel, get a t-50, or t-55 torx for a half in. ratchet. remove the upper and lower bolts, caliper slides off. If it is rear, remove wheel, get an 18mm wrench and take the bolts out. caliper will come out with them.
To remove the upper right motor mount on a 2002 Cavalier with a 2.2L Ecotec engine, first ensure the vehicle is securely lifted and supported. Remove the bolt securing the mount to the engine and the bolts that attach it to the frame. You may need to remove any components obstructing access, such as the air intake or battery. Once all bolts are removed, carefully lift the mount out of its position.
* Remove the cap from the brake fluid reservoir.remove about two thirds of the fluid from the reservoir * Loosen the rear wheel lug nuts,raise and support the rear of the car on securely on jackstands * Remove the wheels.Work on one brake assembly at a time using the other assembly as a reference * Clean the brake assembly then remove the parking brake cable clip and unhook the cable from the lever.Unscrew the upper caliper bolt * Pivot the caliper out of the mounting bracket and remove the inner pad and the outer pad * Remove the upper and lower pad retainers.Remove the anti-rattle spring from the caliper and inspect it;if its cracked or otherwise damaged replace it * Remove the shims from the pads to use on new pads.Wipe off the caliper pin and lubricate it with high-temperature grease,then reinstall it in the caliper mounting bracket
Besides going to local mechanic..1 buy new breaks specifically for your vehicle get rotors while your at it.Step 1 - Identify Front Disc Brake ComponentsMost front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits road conditions and brake pad material used.Step 2 - Remove Brake Caliper to Replace PadsLocate primary caliper mounting bolts; apply wrench pressure counter clockwise to remove the bolt, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.Step 3 - Remove Front Brake CaliperAfter removing the primary caliper mounting bolts lift the brake caliper mounting lift brake caliper off of the rotor and then tie or set gently to the side, be careful of the brake caliper flex hose not to bend or kink it. Thoroughly inspect brake caliper and brake hoses for leakage and replace as needed. Next loosen the brake pads and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.Step 4 - Remove Brake PadsRemove brake pads, make sure if there is anti rattle hardware to transfer to the new brake pads.Step 5 - Remove Caliper MountFinish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad mounts.Step 6 - Remove Brake RotorWith the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use an oil penetrate. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.Step 7 - Depressing the Brake CaliperTo install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston.Step 8 - Installing New Brake RotorInstall new brake rotor, the new rotor is manufactured with a protective film over the rotor, remove protective film before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.Step 9 - Installing New Front Brake PadsReinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are not too lose or too tight in the caliper mount, it must be a close fit to work properly.Step 10 - Reinstall Front Brake Caliper
1. Remove the cap from brake fluid reservoir 2. Loosen lug nuts, raise the vehicle and support it securely 3. Remove the wheel 4. Using a large C-clamp push the piston back into the caliper 5. Remove the caliper mounting bolt 6. Swing the caliper up and secure the caliper with a piece of wire 7. Remove the lower and upper anti-rattle springs 8. Remove the outer brake pad and shim 9. Remove the inner brake pad and shim
Drain, remove upper/lower hoses, fan & shroud. Remove top mount plate (if applicable) Lift straight up.
Remove lower caliper bolt (actually the upper one is a pin), lift the caliper, replace pads. The clips and the bracket might however need some cleaning.
