On a Lincoln LS 2001 how does one get the rear break piston to retract as using the usual C clamp retraction method will not work?

The easiest way is to go to a parts store and purchase the tool made for screwing down the piston. I think it's like $10 for the cheap one and you just put it on the end of a ratchet. You can fit it in the small grooves on the piston and turn clockwise and it will go down.

You can also use the wrench for removing the nut on most grinders. The one from a DeWalt grinder works perfect.

AnswerI haven't worked on one before, but I'd be tempted to back off the brake fluid bleed screw and see if I can retract the piston then.

I replaced the rear pad's on my 2000 ls and there is a square box tool that's supost to fit inside the piston and the you use a ratchit to turn it in I went and bought the tool that's supost to fit but it didn't work so used a rag and channel locks to turn it in

Answerthey screw in..turn and apply presure helpful hinti just replaced the rear brake pads on my wifes 2002 Lincoln ls. i loosend the bleeder screw a little and used channel locks to turn the piston down. didn't look like it was working at first, then it started going down real easy. i almost had to learn the hard way! be careful not to tear the rubber boot around the piston, take your time it will work. i didn't have to apply pressure the piston and i didn't have to fool with the emergency brake line.

P.S. There is a tool that you can usually borrow from your local autoparts store. It turns and presses the piston at the same time. I worked for three hours trying to get mine to compress and finally went to get the tool. It only took about ten mins per wheel after I had the tool. It is worth it. you could do it in their parking lot pretty much. ~good luck~

You need to turn the piston clockwise and it will slowly retract as you turn.

The piston is not stuck. It must be rotated to retract it. There are two depressions on the piston face. Use a pair of needle nose pliars to turn the piston clockwise to retract it. Turn it until the face of the piston is flush with the boot.

you must turn piston clockwise as you push it in

I go to AutoZone and borrow their caliper compression tool. Follow the instructions closely. The piston is screwed in with the tool in a clockwise rotation.

I've found the best way to retract the piston is with a C-clamp, before you remove the pads. I've used this method for many years. Bill F

Hi there ! I have just renovated my front and rear brakes om my Passat 1.8T 1998. This is the way to retract the rear Lucas caliper piston: You need to press and clockwise twist the brake piston in the caliper. First I tried with my standard tools but it was to hard so I purchased a special retraction tool f

When there is to much resistance to retract the piston, When the rubber piston(s) boot/seal is damaged/torn, When the bleeder is broken/stripped,

Try bleeding your brake lines, you may have some gunk in there.

flip the lever/switch again, it has both an on and off function *if you want the block to retract with the piston, you need a sticky piston

You need to turn (screw, rotate) the piston clockwise in the caliper a large number of times to make it fully retract. You can insert some kind of tool into the indentations in the face of the piston, or grip the very top edge of the piston with pliers in order to turn it. It has to be fully retracted to allow enough space for "new" pads to be installed.

Compressing the rear brake caliper piston on a 2008 Chrysler Town and Country requires a special tool that pushes in and turns the piston at the same time.

Use a "C" clamp to fully retract piston into caliper body

User Avatar

Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body

User Avatar

a special scanner called a v.a.g. has to be used to retract the electronic e brake system, and will also retract caliper piston..DO NOT TRY WITH OUT TOOL !!!!!

the piston on the rear calipers will turn in a clockwise motion and that is how they retract.

User Avatar

If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body

User Avatar

if it's like older jetta's or most imports you need a special tool{or a channel lock pliers} to turn the piston back in

User Avatar

There is a seal kit that includes an o-ring and the boot. The piston needs to be spun out, similar to how you spin it in to retract it.

User Avatar

you need to use a rear brake caliper piston turning tool... you can't use the push method... the piston have to be turned as they screw out as the pads wear. i found out the hard way.. i broke 2 c-clamps...
