The caliper piston has to be turned or screwed back into the caliper using a special tool that you can buy from any auto part store. The tool is usually square and fits on a 3/8" drive extension, it has protrusions on each side to fit into a different notch pattern on the caliper piston to turn it.

Do not use a caliper piston compressor or a c-clamp to compress the caliper piston or it will be damaged.

Im trying to change front pads on a3 2005 but cant get the piston to go back


Get a C Clamp large enough to fit from the back of the caliper to the piston. Put a piece metal across the the piston and tighten the c clamp onto the piston as far as it will go. This will push the piston in to put the pads on the caliper and to be able to fit the caliper back onto the brake rotor after installing the pads.

Just taken the old brake pads off the car and the pistons wont move in order to get the new pads on


With the new pads in place, loosen the bleeder valve a few turns while applying pressure to the pads. A small amount of brake fluid will likely spray out as the pads and pistons move, so have a pan or a rag ready. Once the pads are flush with the edges of the caliper, retighten the valve - making sure that the pads don't move.

Trying to fit new pads to vw touran rear axle and have pushed piston back enough to get it off but cant get it back in any further to fit it over new pads and disk, wont fully retract or cant get it to ?


Try removing the brake reservoir cap under the hood where you fill the brake fluid up. This will release some pressure also use a c-clamp if you haven't already to push the piston.

Hi im trying to replace brake pads on the rear of my ford focus 2006 st3


if you are having problems with getting the piston to move back to fit the pads in, you need to screw the piston in using an allen key.
if you have forcefully tried to push it in it may be permanently damaged.

Changing the rear brake pads on 91 mu


Chalk the front wheels, car is on jackstands i hope, release the handbrake, use the old pad with a c- clamp to compress the pistion on the caliper, install new pads. may have to take the cap off the master cylinder, if none of this works, open the bleeder valve, and compress the piston, rebleed the caliper.

Rear brake calipers


A big pair of channel locks will collaspe the caliper but it does take some muscle or you can release the brake line nut and releave the pressure but then you would have to bleed the brakes.

Mitsubishi Montereo - Rear Brake pads


you must spread the pads out....do this with a wedge-shaped tool and use lever action to push the caliper pistons back to the fully-retracted positions in the cylinders. The pistons are currently in the position where the last pads had allowed them to extend to. It is good practice to (excercise) the pistons at pad change time by moving the pistons back and forth slowly to remove any oxidation at the cylinder walls, but never allow pistons to fully extend...prevent this by using a piece of wood to act as the thickness of one rotor and 2 pads. You extend the pistons by using the car's brake pedal, then retract them with the wedge.
