Can't remove front caliber

Use WD-40 rust inhibitor spray. Let it soak for a while,repeat a few times and it should break loose.

Only the rust lip on the rotor holding it on

Sand down some of the outer edge or just
pull the caliper toward you, to compress the piston

Those rotors will need machining

Try the Raybestos Ceramic Pads

You have a collapsed rubber brake hose,not allowing
fluid to return & release the caliper

Do both sides

You should know how old the calipers are &
if you have been changing brake fluid ever two
years
If not, then their all rusted & frozen

Your brake caliper or your brake hardware is sticking. Pull it apart(two bolts) and push the caliper back in with a spreader or a c-clamp. The grease the brake hardware(where the bolts go in). That might do the trick. If you have a hard time getting the caliper peston back in then you need to replace it and bleed the brake system.

First thing to check is the slide pins on the calibers. Make sure they are clean and free of any rust. If not, replace them. If they are not rusty then clean & lubricate them with a very small amount of grease. Your brake system on this vehicle is 20 years old. Have you ever changed the brake fluid? If you are like most people the answer is no. I recommend you flush the entire brake system and install fresh DOT3 fluid. Look closely at the flexible brake hoses that connect to the caliber. They may be collapsing and I recommend you replace them on a 20 year old vehicle. I would also recommend you replace the calibers on the front. With new calibers, brake lines, and fresh fluid you should have great brakes. If you still have the problem replace the master cylinder.

Jack up the front end remove tire onthe brake pad assembly there will be two Hex head bolts these will be probably a 3/8 u can use a big Alan wrench u will also need a small pipe to use a breaker bar and some WD 40 as these bolts are probably rusted just a bit,once u have the bolts out u should be able to remove the brake pad assembly,u might need a rubber malet to help with this,OK u got this off take the new brake pads out of the boxs,pay speial attention to the back of them,now take a big screw driver a pry just one of the brake pad off if u do the side with the caliber on it,(this is the round thing that pushes the brake pad on to the disk to stop the car)There is a clip take this clip off look that the back of the brake pad find the new brake pad that has the same notches in it put the clip on it the same way it came off put it back on the caliber,ok take the other one off,nothice the clip might be made in to the brake pad assembly on this side if not put clip in to same notches,Ok now u have replace the brake pads u will notice that the brake assembly will not go back on, not to fear take a Clean rag place it on the pad on the caliber side get a pair of channel locks now compress the caliber abit now it should side right on replace bolts and u are good to go do other side the same way.

To remove the front disc brakes , you must remove the break caliber assembly . Keep in mind that on some brake calipers a special Torx Drive T40 or T45 must be used to remove the caliber bolts from the spindle assembly . Also , Allen (Hex) bolts are sometimes used . Be sure you have the right tools .
1. Properly block both rear wheels at the front in the back of each wheel.
2. Loosen the lug nuts on both front wheels one turn on each nut.
3.Jack up and support the front of the car on Jack stands with the wheels one to 2in. off the ground.
4. Remove the two bolts on the inside of the caliber the secure it to the spindle .
5.Once the bolts have been removed the caliber should pull straight away from the rotor and spindle assembly .
6.Remove your old brake pads , clean the assembly , properly lubricate the moving parts as necessary , especially the floating sleeve as the assembly is called a floating caliber which means half of the Caliper is bolted to the spindle (inner) but the other half floats (outer).
7.Use a large see clamp centered between the caliper piston and caliper housing to push the piston all the way back into the caliber cylinder by turing (1 turn at a time) the screw until the piston is flush with the caliber face .
8. Install your new brake pads .
9. use the reverse procedure to assemble everything back together. Good luck and be safe....

If this is a metal line tube nut on a flare fitting, then make sure you are using a line wrench. If rusted try PB blaster or another good penetrating oil. As a last choice it may require heating the caliper slightly where the line screws in with a small torch or induction heater. Use caution not to burn yourself or catch the car on fire. Most penetrating oils are flammable. Once the line brakes loose gradually work it back and forth until it loosens up.

If it uses a bolt with copper sealing washers then you can use the same procedure. Leave the caliper mounted and use a 6 point socket and ratchet to brake the bolt loose. If this does not work try an impact gun and the appropriate 6 point impact socket. Just remember to be patient.

In the event that these methods fail or if you overheat things with the torch and damage the hose then you can probably replace the brake hose for $20 to $30 but don't forget you gotta get the fitting on the other end of the hose loose without damaging it also. Good luck.

fill master cylinder, slowly close of brake lines to be sure you have pressure from master cylinder, pump brakes to check master, check that calipers were seated in housing properly

You don't have calipers in drum brakes. you have wheel cylinders that activate the brakes when pedal is pressed. The brake cylinder is located at the top of the brake backing plate on the rear wheel. the brake line is screwed to it on the outside and two small bolt hold it in place. remove your brake springs, shoes etc., then remove the brake line and bolts. Before removing the brake line and bolts spray them with WD40 or something similar to loosen the rust around the fittings.
