You have to rotate the piston in the caliper counter clockwise-I use a pair of long-nose needlenose plyers to do this, spread them and push them against the caliper piston and turn it in.

Whenever I do a brake job - I always use a big C-clamp to compress the cylinder. sometimes it is easier to also open the air bleeder while you are compressing, ( a bit messy - but works ) -- just remember to bleed all the air out when you are done.

Now I've changed rubber brake hose and hard line to the T on rear axle, bled system and left rear brake still drags. All new pads and rotors all around and new calipers in rear. And great pedal.


the callipers actually slide on two pins that are part of the mount to the axle. this sliding action allows the callipers to centralize over the rotor disc
if you are experiencing a dragging brake then remove the pads and see if you can slide the calliper on those pins
if not you will have to remove the pins and clean the rust and gunk out of the holes in the calliper
they do rust up and seize which gives dragging brakes especially after fitting new pads.

2006 ford focus rear brakes


If the piston is stuck out this is due to a seized calliper however a temp Fix is to turn the piston clockwise to force it back in as rear callipers are self releasing so they need to be turned clockwise they will not go stright back without turning. This is due by broken calliper seals although you will temp fix it, It's best to either replace calliper or buy a calliper fixing kit which includes all the seals that need replacing.
Also You will need to Empty the brake fluid out to make it easier to push the piston in it, Then you will need to bleed the whole brake system once fitted back.

Rear pisttons on ford 500 will not push in to install rear brake pads


If you have disk brakes, and you cannot fit the new brake pads in the callipers? Loosen the brake fluid reservoir cap to allow pressure to escape. Use a large C clamp connecting it to the front and back of the piston. Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads.

How do i change my rear brake pads. i cant get the calliper to compress


I don't think you use a C Clamp on the back brakes, you turn it in with a large flat screwdriver.

1990 SAAB 900S REAR BRAKE CALIPERS


Sorry, gentlemen; NO 'C' clamps should be used on the rear callipers of 1988 to 1993 and 1994 convertible SAABs! Unless you want to replace the callipers, that is...

There is a calliper adjusting screw, at the rear of the calliper, hidden behind the parking cable. Unhook and remove the parking cable from the back of the calliper. You'll see a hex head located on the back of the calliper, between the hook to attach the end of the parking cable, and the hole through the bracket where the cable passes to the front of the car. The hex head is most easily seen if you hoist the car; it's not the most obvious until you've found at it a couple of times, then you can do it by touch with the car on a jack stand and without getting underneath!

Remove the hex head bolt, about a 12 mm or so wrench/socket, and you can then get at the calliper adjusting screw to tighten or release it as appropriate; the adjusting screw has an internal hex head socket, use a 4 mm Allen key. Likely the adjusting screw will be a bit stiff; spray into the hole with penetrating spray and let stand a few minutes before trying the Allen key.

Good luck!

Unable to compress rear brake caliper is this caliper shot?


There is a tool that you can buy or rent at the parts house that you can connect to a hand tool EG: 3/8 rachet to use with a tool to compress the caliper while you turn the rachet. You will see some raised teeth on the calliper piston for the tool to bite on. Since the rear brake is used to lock the parking brake it has to have a self adjust to compensate for the brake pad wear. EG: Old school drum brakes adjust when you back up depressing the brakes and letting off while the vehicle is rolling allows for the adjuster to reset the brake shoe clearance.

How to change back brakes? I can't get the brake cylinder to go in.


Do you mean back brake pads or the back brake callipers?
To change pads you need to use a rear brake pads changing tool to screw in the calliper piston or if you are experienced enough you could screw in the calliper with a two mm thick piece of metal sheeting that fits into the grove of the piston.
If you need to replace the whole calliper remove the hand brake cable first and clamp the flexible brake hose remove brake hose, remove the callier with cylinder and then remove the calliper holder. fit new holder pads and locks and the calliper with the piston and the brake hose and the hand brake cable. Bleed the brakes. Mike

2000 Chevy Can't compress brake cylindar


it may be that the flexi brake hose is perrished on the inside and not letting the fluid back up the system. try pushing the piston back with the bleed screw out, if this works then a collapsed flexi hose is favourite. if this is a rear calliper then they may be the screw in type, does the calliper have a lever on it for the parking brake.
