I would think as cheap as remanufactured calipers have become, it would be easier to just change out the caliper. I really do not think you can do it with the piston in place.

    Thank u for ur quick response. I dont want to change the caliper cause its in perfect condition. I was changing the brake pads when i nicked the dust boot on the front caliper. I have not driven the car since then (3 days ago). i know that there is no pitting or any other problem with my caliper. Since im not very good with bleeding the brakes i was wondering if i could just push back the piston and just replace the dust seal. So what do u suggets. Thank you.

SOURCE: Changing front brake pads

You shouldn't need to remove the calipers altogether just to replace the pads. You have remove the split pins or retaining springs on the old pads, then prize back the caliper pistons enough to remove them. Then push the pistons back some more enough to get the new pads in. Then reassemble and test.

SOURCE: 1989 toyota pickup front disk brake pads replaced, now the front calipers wont clear the new disk brake pads! Any solutions, please?

remove caliper, push disc all way home, put wheel nut on to hold home, retry fitting them the disc may be slightly scued. If no go try diffrent brand of pad I had same prob with a diffrent car last week & diffrent brand pad was 2mm thiner. If can't exchange pads get piece of emery paper on flat surface & sand away top part of pad material in round motions both ways till they fit. :-)

Why are my 1995 Buick Regal front brakes lock up

sounds like brake calipers are seized up

After replacing the front brake pads and rotors on my 2001 mustang the calipers are not releasing enough , you can hardly turn the front wheels by hand and the brakes are running hot . How do I get th

Calipers retract after the brakes are released by the slight wobble and rotation of the rotor. What is probably occurring on your vehicle is that the caliper pistons, having been extended due to the worn pads, may have developed rust ridges that prevent the piston from retracting completely. You may have to carefully extend the caliper piston(s) without dislodging them from the bore, then I would first use a brake cleaner on the piston surface. If that fails to work, very fine emery may work. Be sure to remove all residue to prevent seal damage. Do not use any unrecommended solvents as they can damage o-rings and seals

When you change the brake pads front and rear on a 2007 dodge charger do you push the brake calipor in or do you have to push and turn the calipor in at the same time

On the front calipers, you just push the piston back into the caliper assembly, taking care to clean the dust boot off first. I would also be watching the fluid level in the master cylinder so it doesn't "overflow". Your rear wheels have whats called "drum in hat" style. Your parking brake is a pair of shoes that are in the rotor, so your pads are like the fronts, just push the piston back into the caliper after cleaning the dust seal.

Front end pulling to left

Your RIGHT side brake disk caliper is probably siezed so all braking power is going to the left causing the pull.
Wheel off, disk pads out, pump out the pistons in the caliper JUST A LITTLE. Clean with a copper brush and brake fluid until polished (Careful not to catch the rubber dust seals). Push pistons back in. Re-fit pads and wheel.

Other thoughts on this. Check for a lip on the disk caused by wear as well.

That's the super cheap, pay nothing for parts option. You should consider:
Changing both sets of brake pads
If the disks are worn, changing the disks too (you may be able to grind a lip off if you have the nerve).
If the caliper still sticks, new pistons or piston and caliper

Change front disc brakes

Except Srt-4
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove the front wheels.
  3. Remove the 2 caliper to steering knuckle guide pin bolts.
  4. Lift the caliper away from the steering knuckle by first rotating the free end of the caliper away from the steering knuckle. Then, slide the opposite end of the caliper out from under the machined end of the steering knuckle.
  5. Support the caliper from the upper control arm to prevent the weight of the caliper from being supported by the brake flex hose that will damage the hose.
  6. Remove the brake pads from the caliper. Remove the outboard brake pad by prying the pad retaining clip over the raised area on the caliper. Then, slide the pad down and off the caliper. Pull the inboard brake pad away from the piston until the retaining clip is free from the cavity in the piston.
  7. If required, the rotor can be removed by pulling it straight off the wheel mounting studs.
To install:
  1. Clean all parts well. Inspect the caliper for piston seal leaks (brake fluid in and around the boot area and inboard lining) and for any ruptures of the piston dust boot. If the boot is damaged or fluid leak is visible, disassemble the caliper and install a new seal and boot (and piston, if scored).
  2. Inspect the caliper pin bushings. Replace if damaged, dry or brittle.
  3. Completely compress the piston into the caliper using a large C-clamp or other suitable tool.
  4. Lubricate the area on the steering knuckle where the caliper slides with high temperature grease.
  5. Reinstall the rotor if removed.
  6. Reinstall the brake pads into the caliper. Note that the inboard and outboard pads are different. Make sure the inboard brake shoe assembly is positioned squarely against the face of the caliper piston.

    NOTE Be sure to remove the noise suppression gasket paper cover if the pads come so equipped.

  7. Carefully position the caliper and brake shoe assemblies over the rotor by hooking the lower end of the caliper over the steering knuckle. Then, rotate the caliper into position at the top of the steering knuckle. Make sure the caliper guide pin bolts, bushings and sleeves are clear of the steering knuckle bosses.
  8. Reinstall the caliper guide pin bolts and torque to 16 ft. lbs. (22 Nm).
  9. Reinstall the wheels and torque the lug nuts to 100 ft. lbs. (135 Nm).
  10. Pump the brake pedal until the brake pads are seated and a firm pedal is achieved before attempting to move the vehicle.
  11. Road test the vehicle for proper operation.

  1. WARNING: Asbestos fiber dust may be present on brake and clutch assemblies and is hazardous to health if inhaled.

    Brake and clutch assemblies should be cleaned using a vacuum cleaner recommended for use with asbestos fibers such as brake/clutch/service vacuum. The bag must be labeled per osha instructions, sealed, and the trash hauler notified as to the bag's contents.

    If a vacuum suitable for asbestos is not available, cleaning should be done wet. If dust generation is still possible, technicians should wear government-approved toxic dust purifying respirators.

All new brake shoes on 97 jeep front callibers still sticking

The problem lays with the Caliper itself and/or the brake hose connected to the Caliper.
However if you replaced the pads, did you also replace the Rotors or have them Turned? The old pads wear the rotor. New pads on old rotors that have not been replaced or turned may end with rubbing or stuck brakes.
A simple way to test whether it's one and/or the other:
1. Remove the Caliper from the rotor, remove the pads. Keep for now the caliper attached to the brake hose.
2. Very slowly push on the brake, exposing more of the piston out of the bore. Not all the way. Usually until the rubber dust seal/boot is fully extended.
3. Check the seal/boot for cracks and tears, and if clean or not. Bad seals may prevent the piston from re-seating.
4. Using a c-clamp and pushing straight in: Try repushing the Caliper Piston back into the Caliper Bore (the cup back into the hole). It should go back in realitively easy.
5. If it doesn't go back in easy: Again slowly pump the brake and re-push the pistons back out to full extended seal/boot (but not the piston out of the bore).
6. Detached the brake hose from the caliper.
7. Again using a c-clamp and pushing straight in: Try again to repush the caliper piston back into the bore without the hose attached. If it goes back-in relatively easy - the caliper is is the brake hose.
8. If the caliper piston does not go back in easily - Replace the caliper.
9. When Installing the new (reman) caliper, remember to bleed the brakes.
After the new Caliper is reattached to hose and has been bled:
10. Again push on the brake petal to fully extend the caliper piston fully (rubber seal/boot fully extended) Again do not push the piston out of the bore! Try pushing the piston back into the bore. If it does not re-seat relatively easy: Replace the brake hose.
11. Another method: After replacing the new caliper back on the rotor: Assumng the entire front end (2WD front wheel drive) or entire vehicle (2WD rear wheel drive) or (4WD all the time) is jacked up off the ground
a. Put the lug nuts back on the rotor.
b. Have helper Start the vehicle and place in Drive. Don't step on gas!
c. Have then let off the brake and then engage the brake.
d. When they let off the brake watch to see if the Rotor is turning or not, if rubbing or not. Or if still sticking.
e. With a new caliper, turned or new rotors, and still a problem? It is the brake hose!
12. Replace the brake hose and try again.

Another method but more expensive:
OR Replace the calipers, brake hoses; bleed and test!

If this helped or not; or if you need additional help or have addtional questions let me know on!

Sticking brakes

It seems the front brakes are jamming, thiscould be the caliper piston being corroded and since it wa sdriven to its max the piston have travelled way too out forthe dust rubber to be able to protect the dust or water getting through.
The best remedy would be to overhaul the front brake calipers, best would be to remove dismantle and examine if the pistons are ok with no burr or rusty around it.

Good Luck.

How do i replace the front caliper seal on 06 malibu maxx??????

while the seals in the calipers are replaceable, its probably easier just to get a new/re manufactured caliper. if for any reason the seals don't work perfectly you could lose control of the vehicle when attempting to stop. with that said i'll try to explain the best i can how to replace the seals in the calipers for that vehicle.

1. jack up the front of the vehicle, place on jackstands and remove the front wheels, make sure the parking brake is on
2. unbolt the caliper and unbolt the brake line from the caliper and take caliper to a clean bench
3. remove the dust boot retaining ring on the caliper that holds the boot to the caliper itself
4. using a blowgun with a rubber tip apply low pressure compressed air where the brake line was bolted to the caliper to push the piston out of the bore (be carefull and ready because the piston may shoot out with some force)
5. when the piston comes out you will need to replace the dust boot and the seal so remove the boot and seal carefully so you don't scratch the piston ( the seal is actually in the caliper piston bore hole)and throw out the old seal and boot.
6. inspect all the surfaces and make sure there are no imperfections at all on the piston, the piston bore, or the caliper, if the surfaces are marred in anyway, replace the caliper, if they are good, using brake cleen and compressed air clean all parts then dry them
7. get the new seal and lubricate with DOT 3 brake fluid
8. install new seal into the caliper bore
9. apply a thin coat of DOT 3 brake fluid to the piston itself
10. install bottom half the the caliper piston into the caliper bore.
11. install new dust boot seal onto the piston
12. compress the piston to the bottom of the caliper bore
13. fully seat the dust boot seal into the caliper and install retaining ring
14. reinstall on vehicle (make sure to use a NEW copper washer on the brake line to caliper fitting) and bleed the braking system while checking for leaks.

repeat process for the other side.

if the caliper leaks at all from the piston after seal replacement, replace the caliper.

make sure you properly bleed the brakes before attempting to drive your car.

*these direction were extracted from personal experience and manufacturer information*

any other questions just ask!

Toyota camry 1994 wide body 2.2

Hi nanadevi,
There are two rubbers fitted to each of the caliper pistons.The outer one is a dust cover and the inner is the seal.... i you've removed the inner, you'll have to refit very carefully, not causing any damage....Lubricate with rubber grease and open the bleed nipple....push it in gently....The dust cover fits over the caliper housing and tapers outwards to fit the piston....

Hope that's a help?
