172 Front Caliper Piston

[MrBlonde]

Im rebuilding my front calipers tomorrow and replacing seals,slider pins etc.How do people remove the piston if you dont have compressed air to use to blow the piston out?.can you simply just pull it out with a pair of grips?

I would have thought so, the pistons do protrude about 5 mm so plenty to get a grip on.

yeah i was thinking that to and they just slide in & out being there not screwd like the rears.

If the calipers are still on the car ? You can remove the brake pads and carriers and gently press the brake pedal , the piston will pop out that way . Obviously you're gonna lose some fluid , but you can clamp the hose afterwards.

Yeah ive not started doing them yet,starting in the morning.I was thinking i dont even need to take the caliper completely off either.

footpump will do it if you dont have compressor mate

Caliper off, remove bleed screw & drain, mole grips and a cloth, gently tease piston out. Not sure if that's right or wrong but worked for me and the calipers had been sat in the shed for the last 2 yrs.

Unless you are replacing the piston don't go anywhere near it with grips etc.
