How do you push in the rear pistons? because they are unlike the front ones.. I spoke to a guy and he said to twist the pistons.
anyone know for sure?

thanks

Youll need a special brake caliper tool to do it, it will look like this

There is also a Ford specific rear piston retractor that is round in shape. Last time I checked Repco was selling it for ~$50.

ABW make a round one and I thought it was around $20 and it works better than the cube. However the $12 cube one works really well for removing the timing chain tensioner reatiner on the I6 engine. On special tools I see Marlows now carry a $25 Ampro tooll for holding the fan on both the 6 and V8 Fords.

If yer piston is not worn on the lip edges, you can use a flat bladed screwdriver like i did, wedge it between the 2 grooves but
only if you cant get that tool. Its a pain in the bum! I also used a set of BIG pliers to grip and turn the lip of the piston, which also worked well..

you can simply screw the hand brake connection (where the handbrake bracket bolts on) inwards and the push the piston in till it sticks out again, continue this until the piston is far enough in. Make sure you keep the piston straight though as it is hard to turn without the special tool talked about above (and you wouldn't be using this technique if ya had one

You can't use the square tool on the ford calipers, it's not big enough to sit over the entire piston and all you'll do is wreck the tool and get nowhere. The specific falcon rear caliper tool is $36 from repco and will do the job perfect, just be aware that not all stores stock it, it may need to be ordered in, I had to get mine from the repco warehouse which isnt far from me.

Using pliers or multigrips is pointless aswell, you also have to push the piston in while turning it. And make sure you lubricate the seals with brake fluid to prevent them tearing, the only thing stopping ur brake fluid reaching the air is that seal, keep it in one piece at all costs.

Ed, maybe pointless for you buddy, but thats how i did mine and it worked well...

you dont need a tool!!!

undo the spring from the handbrake lever (at the caliper)

undo the cable from the lever

undo the 13mm bolt from the back of the caliper

remove the handbrake lever

you will see a rubber seal and in the middle is a bolthole but with two flat edges - get an adgustable spanner and turn this carefully to find out wich direction will pull the piston back, then just wind it in - EASY

remember to put the ruber seal back in though.
