Re: rear brakes on 1998 mercury sable
Actually theres a special tool that connects to an air pump hose that expands the caliper back but you can use a vise if your very careful with pressing it back or locking clamp that you can use like a vise but this requires hand presure loosen bleed screw then use the vise
If it's anything like my old 93 Sable, you will have to disconnect the parking brake cable from the caliper before you can retract the piston. You should be able to do this with rudimentary tools - screwdriver, pliers. Also, the pistons on those type of calipers will NOT compress back into the cylinder. You will need to get a piston-retracting tool from your car parts store. These types of pistons need to be screwed back in by getting this tool and using a ratchet to press & turn at the same time. Have a swear jar and a few bandaids handy.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Remove the caliper mounting bolts and remove the caliper. Replace brake pads as necessary. Special tool is required to retract caliper piston to fit over new pads. (see picture below) Retract piston in caliper using special tool to rotate clockwise and make sure the notch in the piston is aligned properly so the tab on the inner pad will fit in properly. Reinstall caliper assembly and caliper mounting bolts.
they r a self adjusting cable....if ur sable has rear drum brakes then adjust the rear shoes...if it has rear disc brakes then u have a faulty rear brake caliper..the parking brake system is also inside the rear brake calipers

1999 Taurus, Sable Workshop Manual
REMOVAL AND INSTALLATION
Brake Shoe and Lining
Remove brake master cylinder filler cap (2162). Check fluid level in brake master cylinder reservoir (2K478) . Remove brake fluid until brake master cylinder reservoir is half full. Discard removed fluid.
Raise vehicle on hoist.
Remove wheel and tire assembly from front disc brake rotor mounting face. Use care to avoid damage or interference with disc brake caliper (2B120) , front disc brake rotor shield (2K004) or front wheel knuckle (3K185) .
Remove rear brake pin retainers (2N386).
NOTE: It is not necessary to disconnect hydraulic connections.
Lift disc brake caliper from front disc brake caliper anchor plate (2B292) and front disc brake rotor (1125) . Do not pry directly against metal caliper piston or damage will occur.
NOTE: To prevent damage, do not allow disc brake caliper to hang by the front brake hose (2078) .
Position disc brake caliper out of the way.
Remove inner outer brake shoe and lining (2001) assembly from front disc brake caliper anchor plate .
Inspect both rotor braking surfaces. Minor scoring or buildup of lining material does not require machining or replacement of front disc brake rotor.
remove the 2 pins, #10 in pic. Usually has a dust cover over pin accessopening. Usually torx haed or hex head bolts (pins).
the caliper has 2 bolts that must be removed and the caliper then comes out.you will after removing the old pads need a caliper piston compressor tool or the new pads will not fit.If you want to remove the rotors,you will need to undo the caliper bracket bolts and remove the bracket.Then the rotor will have to be hit a few times in the center by the studs with a hammer to knock it loose.Be careful not to hit the studs,as the threads can be damaged.Apply a silicone brake lube to the metal pad backing plate and lube the caliper slide pins after cleaning the old lube off.Do not use never sieze on brake parts.Be careful not to get brake lube on any pad surface.use a brake cleaner to remove it if you do.Shims have to be used if they are equipped with them or the brake pads will vibrate.
If you can't see diagrams(sometimes happens) let me know and I will get them to you
Raise and support the vehicle. Remove the rear wheels.
If equipped, disconnect the brake pad wear sensor from the harness.
Counterhold the lower sliding pin using a thin open-end wrench and remove the caliper-to-sliding pin hex bolt.
Pivot the caliper upward or if necessary remove the upper caliper-to-sliding pin hex bolt.
a brake caliper retraction tool, select the appropriate sized piston
press arbor and install the tool onto the brake caliper. Following the
tool manufacturer's recommendations, use the tool to rotate the caliper
piston clockwise as it is pressed into the brake caliper housing, until
it is fully retracted.
Use a thin open-end wrench to . . .. . . support the caliper sliding pin when removing the caliper mounting boltUse a disc brake caliper piston retracting tool that will rotate the caliper piston as it is pressed into the caliperThe rear caliper piston is slotted to allow a retracting tool to rotate the piston when replacing the brake padsTo install:
the brake caliper and all sliding surfaces. With the caliper piston
pressed fully back into the caliper housing, check for leaking fluid
and damaged dust boots.
If equipped, install a new brake pad
wear sensor in the pad if the plastic part has been worn through on the
old sensor. New sensors are not required unless the wire inside the
plastic part has been exposed.
Lubricate the slider bolts with approved brake grease.
the brake pads onto the bracket assembly, and then carefully lower the
caliper over the caliper mount. Check and make sure that the pad
springs are correctly seated.
Replace all removed caliper-to-sliding pin bolts and torque to:
1990-97 Passat models: 25 ft. lbs. (35 Nm)
1998-00 Passat models: 22 ft. lbs. (30 Nm)
equipped, connect the brake wear sensor wire to the harness. Check for
a good connection as most problems with the sensor circuit are caused
by faulty connections. Check that the wire is held by the loop in the
dust cover and the connector is held at the clips.
wheels and hand tighten the lug bolts. Lower the vehicle carefully
until the tires begin to contact the surface and torque the lug bolts
to specification in a crisscross pattern to:
