Caliber bolts are stuck

you will need to 1st get a caliber turning set from harbor freight, it very cheap maybe 35-40 bucks...you need to raise both rear tires,crank the car put it in neutral so that the electric module releases the brakes from park position,then you disconnect the neg battery term.remove the tires, open the hood,remove the fluid reservoir cap,remove the calibers by the two bolts facing the inside,then remove the pads,then take the caliber tooland lock the two male nipples ends inside the female piston plates(u will see how the fit)now make sure the brace plate of the of the caliber tool is snug and begin turning the tool threaded side clockwise,and the bolt near the plate should be turned counter clockwise and each turn will turn the piston inside the caliber until its all the way flush with the inside of the caliber wall itself...then place the pads inside the caliber rotors are the same as removing from any other car,they may need a good tap with a hammer,some may have one alen head screw.But replace the rotors and pads.Once they are replaced,lower the car,reconnect the neg terminal,put the fluid cap back on,crank the car,pump the brakes and hold the center console lever upuntil the brake light goes off and u will hear the rear brake module engage.Hope this helps!

Jack up car, remove the wheels, take out the two retaing bolts on the brake caliber, slide caliber up off brake disc, remove old brake pad, use a C-Clamp or big pair of Channel locks to compress the piston in to the brake caliber, Insert new brake pads onto caliber, slide brake caliber back over brake disc, reinstall the 2 retaining bolts. put tire back on. Repeat this till you have replaced all pads that you are going to change. ***Caution.. Before putting the car in gear, crank it up and pump the brake pedal till you have a firm brake pedal. If you fell to do this you will have no brakes due to the pistons on the calibers are compressed and are not seated on the discs.

loosen lug nuts. jack car up. Take wheel off. take the 2 bolts out of caliber. then remove the caliber from rotor and then remove the brake pads. push back piston with piston pushing tool. insert new brakes into caliber and return the caliber onto the rotor. put the 2 bolts back in and return wheel by tightining in a star order and you are now ready to roll

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....

Thats how I have done it on 2006 250. No C clamp.

remove the two caliber bolts that hold it to the bracket,use a screw driver to put inside inspection hole and pull towards outside of car,now you can pull it off,pop the pads out ,put the new ones in,take a large pair of water pump pliers and compress the caliber piston back in the caliber the whole way,put caliber back on reinstall bolts and then do the other side,before starting car pump brake pedal back up this will push the piston back out against pads then you will have a full pedal again,

Raise and secure on stands after breaking loose the lug nuts and parking brake on for front pads.. Remove wheels and spread old pads back to push cylinders back in their bores on calibers to allow for thickness of new pads. Remove the 2 sliding claiber retaining bolts and rotate caliber out of mount and secure with wire, boungie cord, or rope to take weight of caliber brake hose. Remove old pads, install new, and reassemble in reverse order. Lugs on alloy wheel should be torgued to 95 foot lbs. Block front wheels, release parking brake,and do the back ones the same way. After completing, pump brake pedal slowly several times to seat new pads. If you move the MPV without pumping first, you will have no brakes to stop. If brake fluid level is high in master cylinder, you will need to take some out first to make room for returning fluid from caliber pistons being returned to their bores prior to any brake work. Rotors should be replaced or turned if scored or warped to have better clapping of pads to rotor surface.

You can sometime just pull it off but sometimes you will need to take a screwdriver and push the brake pad back on the caliber piston side. This will force the piston back and allow you to remove the caliber. After you remove it you will need to compress the caliber piston fully back in order to allow room the install the new pads and get them back on the rotor. Sometimes you can fully compress it while the caliber is still installed. On some vehicles like Honda you need a special tool in order to compress the caliber. Most auto parts stores will lend you the tool if you buy the pads from them. Be sure and loosen the master cylinder fill cap to allow the brake fluid to expand in the master cylinder. Clean everything off with spray brake cleaner before installing the new pads and clean the new pads throughly. Be sure and install pads in pairs. Do both front wheels or both back wheels not just one.

To remove the caliper, you need a torx head tool (can't remember exact size) to remove the two slide pin bolts.(inside the two small rubber boots at each end of caliper) After getting them loose, remove the brake hose, then remove bolts and caliper. (don't loose the two copper washers...if they aren't in the new caliper box you will need them.) Check and see if the caliper retracts easily after it is removed. If it does, the rubber brake hose may have internally failed and is your problem. If piston is very hard to move, get a new caliper. Replace both side brake pads, not just side you are workingon. (recommend both calipers as well but most times it works fine with one.
When replacing, make sure slides are free in calipers and thread pins by hand so that you don't cross thread them. After it's back together bleed front brakes and before moving car step on brake to re-set pistons.

jack the truck up and take the passangers tire off. look behind the rotor you should see 2 bolts holding the caliber on to the rotor. loosen those and take them out. from there you should be able pull up on the caliber this will take the caliber and pads off together. take the pads out of the caliber and install the new ones .

BECAREFUL not to twist or bend the caliber to much or you will bend the brake line.....

once you have installed the new brake pads in the caliber. put the caliber back on the rotor. if they will not fit release the bleader valve to release the pressure. than you should be able to slid the caliber back onto the rotor. once you have done that close the bleader valve. reinstall the 2 bolts to hold the caliber in place. put your tie back one. Follow these steps for the other side.

now once that is done. you might want to blead the front breaks.
what you do is have someone help you. fill the brake resiviour with brake fliud. than start your truck.
Have someone in the cab to press the brake. What you want to do is turn the wheel so you can get to the bleader valve. once you can get to it open it up. have the person in the cab other truck press the brake until you see a steady flow of brake fluid coming out of the caliber. once you see that have the pseron press the brake once more and hold it to the floor.
close the bleader valve.

now do the same thing on the other side. But, make sure you check your resivour fluid first.
This is to make sure you don't have any air in the lines. after you are done with both side put it in gear and hit the brake make sure you stop......... If that works go about half the block down and hit the brake again to make sure you stop......
once you have done that and are comfortable with the way the truck stops than ou are good to go and now know how to change the brakes for future refrence..... be aware the back brakes are diffrent.........

let me know when you are ready for the back brakes.
do not blead the front ones if ou intend to do the back brakes afterwarwords......

if you are only doing the front brakes you must blead the the passanger side first......... if you do not have the bolts holding your caliber on than you will have a pin the you will take a hammer to and knock it out that will release them....
