On some vehicles with rear disk brakes the piston also is self adjusting to keep the pads close to the rotors. This piston screws in to back it off. Turn the piston counter clockwise to back it off.

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.

SOURCE: changed frt and rear brake

The piston must be rotated as it is pushed into the caliper. There is a special tool for this that is sold at just about all parts houses. The tool looks like a small square with various pins for various applications that goes on the end of your 3/8 drive ratchet.

I replaced front driverside brake pads and the caliper will not fit why ?


If the piston was not compressed completely back into caliper, ( I use a large C-clamp,) then the caliper/brake pads will not fit over the Rotor. Also when you compress the piston back into the caliper be sure the brake fluid resevoir doesn't overflow when the fluid returns during the compression process.

How do you get the caliper in on the rear of 2008 dodge caravan


You need to compress the caliper piston back into the caliper assembly to allow the new pads to fit over the rotor. A C clamp can be used to compress the caliper piston. Be sure to remove the brake reservoir cap before compressing the piston and remove excess fluid from the reservoir to prevent over filling.

Steps to replacing rear brake pads


A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

How to comress the piston to replace brake pads


2 ways:

1. If caliper is still on rotor, use a small scewdriver to gently pry between the rotor and rear pad. Once loose, use a larger screwdrive, but continue to pry gently and slowly until fully compressed.

2. Caliper off rotor. Put back pad in place and apply a c-clamp across pad to back of caliper. Slowly close clamp until piston is fully retracted.

OK?

Can not get rear break piston to compress to allow for new pads


The rear disk brake piston does not compress back into the caliper, it has notces on the caliper piston that a tool fits into and the caliper piston is actually turned or screwed back into the caliper, and a notch in the piston must also be aligned to fit the the small protrusion from the backing plate of the inner brake pad.

The brake tool can be obtained from most auto part stores, and it is usually square with protrusions sticking out from the sides in different patterns to fit various caliper pistons, and it usually attaches to a 3/8" drive extension and ratchet.

Do not compress this type of caliper piston because the caliper can damaged.

Cant get brakes back on my 1992 gmc jimmy I cant get them to line up and go on the rotor


More than likely you have not fully compressed the caliper piston into the caliper. Take the old inner brake pad and clip it on back onto the piston. With a large clamp (one side on the back of the caliper behind the piston and the other on the face of the old brake pad) and compress the piton slowly by tightening the clamp. It needs to bottom out completely. Remove the clamp and old brake pad and install the new pads. Make sure that when you install the caliper to the rotor that the brake pads stay locked in position and it will slide over the rotors and fit snug.

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.

Changing rear breaks


Try tapping around the rotor hat (the area that actually fits over the hub, where the lug bolt holes are) with a hammer. That usually will loosen up a rotor that's stuck due to heat, dust, etc. As for compressing the rear piston, they're a screw-in design, not a compression design like the front calipers. You need a piston retracting set (you can borrow them from AutoZone), and with that you can screw the pistons into the calipers. After removing the reservoir cap underhood, screw them all the way in so that you have ample clearance for the new pads over the new rotors, then pump the brakes a few times before you hit the road (put the reservoir cap back on first).
