Title: Removing pistons from calipers?
Post by: bobby_fodge on January 20, 2019, 04:02:04 pm

Hi, I've bought some front calipers from a boxster to fit to my golf.

So far I've only been able to extract one of the four pistons.

I can't find a specific tool for it.

Any ideas?

Are they rears that screw in and out or fronts that just slide ?
The wind out one requires a tool
You can remove the sliding ones by using a brake hose clamp on the flexible hose opening the bleed nipple a little and connecting a foot pump the pressure of the foot pump will pop the cylinder out
Do it slowly and somewhere clean
You can use a air line but there’s more control with a foot pump

Think the issue is they are 4 pots? So assume once one remove there isn’t ability to use pressure to remove the other?

They didn't come with any brake hose on them so I don't know where I'd connect the footpump or airline.

Connect foot pump to the bleed nipple, but then you need to block the hose where the hose would be connected
