Hi Joe, loosen the cap on the resevoir and very slowly turn the piston, you'll feel it going back in. (They are threaded)
*Just take your time, do not rush*

Have fun :o)

How do i push piston back in when changing rear break pads


Rear Disc Brake Caliper ?

There is a small tool to turn the caliper pistons
in or retract (that is actually the barking brake)

You also have to push the piston in, after you screw
in the piston,for that you open the bleeder & make sure
you have something across the caliper ,so your not pushing
on the piston with any clamp or other tool

May push in by hand- IF- the bleeder is open

Lots of video you can watch on You Tube

I need to replace brake pads on my car, can you tell me the steps I need to take so it is not difficult for me on my part


Get a repair manual for your car. Libraries also have an extensive car repair section. Disc brake pads are pretty easy to replace, if you have proper tools (You'll also need a large c-clamp, like 4 or 6 inches to push the piston back into the caliper bore.Use jack stands and pull wheel off. remove caliper(usually two bolts) pull old pads off(may be some retaining clips or wire springs holdin them. Reset piston back in bore, attach new pads, and mount back on caliper bracket. recommended to use some hi-temp brake grease (just a thin film on the caliper retaining bolts, and a dab on caliper sliding surfaces [it moves side to side]).Wont go over the rotor? Your piston is not fully seated. When you've done both sides, before you move the car, be sure to pump the brake pedal a couple of times to push the piston back out, else you will take off and wont have brakes till you pump them.Good luck.

If the brake caliper piston will not go back into the piston bore do it need to be replaced.

Have taken apart but cant get new or old pads back on now. not enough space and part that should move back to make space wont seems to be jammed or siezed. have tried letting out brake fluid but didnt...


  • To install: Front
  1. Compress the piston of the disc brake caliper.
  2. Install the brake pads and caliper assembly.
  3. Lubricate the guide pin. Tighten the guide pin to 16-23 ft. lbs. (22-31 Nm).

REAR :
  1. Pull out the pad springs and then remove the pads and shims.

To install:

  1. Clean the piston end of the caliper body and the area around the pin holes. Be careful not to get oil on the rotor.
  2. Carefully turn the piston clockwise back into the caliper body (this can be done with a pair of needle nose pliers). Take care not to damage the piston boot.
  3. Coat the pad contact area on the mounting support with a silicone based grease.
A special tool is available to rotate the caliper piston

WARNING

Do not press the piston into the bore as performed on the front disc brakes. Due to the parking brake mechanism, the caliper piston must be turned into the bore.

How to slacken rear brake shoes to replase disc


Hi Ricky

Your car has disc brakes so you need to release the brake pads not shoes (they are for drum brakes). That should help when you buy a new set.

Loosen the split pins which hold the pads in the caliper. You should then be able to push the pads out. It sounds like the pads are worn down so much that the caliper pistons are at their full reach.

Once you have slid them out, you need a piston retractor tool to push the pistons back in the caliper in order to be able to fit the new pads.

SLide the pads in, use copper grease on the back surface to stop them squeaking. Once done, pump the brake pedal to set the pads and the job is finished.

Compressing the rear disc brake caliper on 2008 grand caravan


The rear calipers on these models require a special tool that compresses and turns the piston in at the same time -- most parts stores carry this tool.

It is called a caliper piston press -- and it installs where the pads would go and acts like a c-clamp,when turning handle it will turn the caliper piston backinto the caliper as it compresses it.
Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the Parking Brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor,MILLER Special Tool 8807, . Any other seating method will damage the self-adjuster mechanism.
Good luck and hope this helps.

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 okay...it 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.
TRY EITHER OR #10 OR #11 BELOW:
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!

Can't compress calipers on rear brakes SAAB 93, 2004


Rear disc brake pistons usually need to turned as you compress them. There is a tool you can rent or buy at most auto parts stores to do this job very easily using a 3/8 drive ratchet . Unless your SAAB is different than most newer cars with rear discs this should allow you to get the pistons back in to the caliper. Ask the counter man for one that fits or just look at the face of the piston to see if there are recesses to fit a certain tool into and match it up.

Mustang rear brakes


nice car i have one myself but the back brakes are a little bit tricky because you can not just push the brake calipers piston back into the bore. but here is how you can do it. you need a large plieres and you have to put the head of the pliers into the calipers piston then spread apart the handels so that the head of the pliers opens up against the inside walls of the piston. then all you have to do is Turn the piston back into its bore. See the rear caliper piston on the mustangs are just like a bolt. they are threaded into the bore and when your pads were they screw them selves out so when you redo your brakes you have to screw them back in just like a bolt. I hope this helps you out on this and if you have any more questions about this procedure just let me know and i would be more than happy to assist you in this.
please rate me if you would
thanks

Rear brake cylinders are stuck, can not push them in


I have a 2004 SAAB 93 and just finished replacing the brake pads and rotors yesterday. On the piston itself you should have two little notches. You can either or a GM rotor reset tool that will push into the two little notches and push against the piston while rotating it clock wise. Or the way that I did it was to take a C clamp and put the caliper back on the car. Clamp it on the back of the caliper to the front of the caliper so it will remain stationary. Then take a pair of needle nose pliers and rotate the two notches clockwise while pushing into the caliper. It will take some strength but you should be able to push them in. Be sure that you spray the boot around the piston when some WD 40 so it does not crack and or break during the process. If you have any additional questions about this feel free to email me.
