How to remove brake caliper pistons

We decided that we didn't want to buy any special tools, so we tried blasting them out with the air blower. Works great!

Dont forget to put in a small board to cushion the impact and keep fingers away. Also, some pistons require a allen wrench or piston socket for removal.

The first time i ever did that, the piston shot around 15metres and narrowly missed a window of a customers car!

@h8ryj I believe it . I rebuilt my caliper today. The piston was stuck, so I too blasted it with compressed air @120 psi. Didn't budge. I had to wiggle it around and then try the compressed air again to remove it. It finally came out. FYI using 120 psi to remove a 2 inch piston will impart about 420 lbs of force. 420 lbs !!!

OUCH! Save your piston from damage by using a small board (like femfeather mentioned) where the piston will smack up against. I use a work glove or rag myself (whatever I can reach the easiest (lazy bastard that I am).

If you end up denting the edge of the piston when it hits like that it will in turn damage the cylinder.
