On cars with 4 wheel disc brakes the rear calipers are what they call racheting.The pison needs to be turned clockwise at the same time you are pushing in.This mechanisum is for the E brake system.They make special tools for doing this that you can pick up at your local parts store.

SOURCE: cant compress piston on rear brake calipers

Use a caliper wind back tool which rotates the piston at the same time as pushing it back. Release the bleed screw to assist the wind back. If you use a brake hose clamp on the brake hose this will reduce the need to bleed the system.

you need a special tool avalable at most parts stores. its a disc brake piston turning tool. you have to rotate piston clockwise while pushing in on piston. you can fabricate something that enguages the slots and push and turn till all the way in.make sure to note position of slots and put them in same place as was before or the pin on the pads wont enguage the slot

How to rebuild the front brake caliper on a 1992 ford explorer xlt


it will be leaking because the piston has corroded and the seal will not work
safest way is to have a brake specialist shop do the job or simply buy new callipers
one side leaking the other side will not be far behind it
plenty of after market units made by the same company that makes them for ford with out the ford name price

04 gmc sierra,quad cab 4x4,front brake locked up and abs light came on,brakes were smoking


Hey Cameron - Usually (Not a Law) it would mean the Caliper is seized. There is a caliper piston - when you press the brake, that piston pushes out, forcing the brake pads to put pressure on the rotor. Your brake fluid is hydraulic fluid - when you take your foot off the brake/it retracts the caliper piston releasing the tension.
There are definitely other things it could possibly be - but if you can get the brake line OFF the caliper housing (attached to the wheel's rotor/where your wheel studs come out of), there will not be any more pressure. I would recommend disconnecting the brake line and applying a penetrant oil to the housing/anywhere you can spray it. (((tip of the day - spray it with brake cleaner first. Douse it. Brake Cleaner - stronger the better - is a very strong solvent - it breaks rust up extremely well, believe it or not - the only downfall is it drys fast - leaving the material open for more corrosion/the remedy - try some brake fluid, let it dry off, then hit it with a good penetrating oil - Get Some, one work search for that. Really effective and non-toxic. Once it's soaked and the brake line is off - leave the caliper in place and see if you can get the piston to go back in enough to get the retaining bolts off and get it off the rotor. E bay is awesome for used parts - but I have a code for Advance Autos coast to coast that isn't advertised that would really help out if you chose to replace new. On some calipers - you can rebuild them (new caliper piston and o-rings that seal the components) but usually a used caliper off of E bay with free shipping is cheaper than the kit. Just an FYI.

Here's the standard procedure (see below).

I've seen a locked caliper more than once. The piston usually gets corrosion in between itself and the cylinder it slids in and out of. Eventually leading to a seized caliper piston either open (when you're lucky) or upon coming to a stop - it will fail to release and go back in. If you get any other information contact me and I'll gladly advise to the best of my ability.

Thanks & All The Best, Justin McCartney

My husband changed front brake pads and now brake fluid leaks drivers side front caliper bolt. Sometimes smokes


If your hubby only changed the pads and nothing else it is likely one of 2 things

- the rubber hose got twisted or jerked and is now partly split (they do so when getting old)

- the piston seals in the caliper are now leaking (when changing pads the piston has to be forced right back in the caliper and sometimes old seals cannot cope with this)

Inspect the hose closely and have the caliper overhauled with a seal and boot kit. Also have the brake fluid flushed and renewed.

No, sounds like just one of your pistons is frozen. Incase you haven't done this yet, also fyi, you have to collapse both pistons at the same time. Try placing a strip of wood across both pistons and squeeze them both at the same time with your C-clamp. If one is hung up, this may free it up, or even it out so it fits back in the caliper properly. Or, I don't know if you didn't know this about both pistons, but if you squeeze only one, all the fluid will push across to the other and push it out, causing it to partially come out and be crooked in the caliper. Good luck!!

I cant seem to get the rear brake caliper to compress so it will fit over the new pads


There are two stlyes of calipers for the rears. One is ratcheting so the piston has to be turned back to colaspe. The other type compresses with a C clamp. If a large retaining spring is on the inner part of the caliper you have the ratcheting type. A brake cable will attach to the spring as well. If not it will compress instead

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.

any other questions just ask!
