Extracting brake caliper pistons

Recommended Posts

Hi

how can i extract the pistons from my calipers?

The calipers were removed during the strip down....now i want to check on the pistons and seals....whats the best way of either getting some pressure to force them out...or pulling them out?

Just staring at them scratching my head at the mo.

Cheers

Nick

I pushed a air foot pump against the inlet. Just be careful, as the piston can leap out! A block of wood in the caliper will prevent this.

Similar to Tony except I made an adaptor to thread into the caliper inlet that connects to a compressor, again I put a block of wood in the caliper to stop the pistons from shooting out, you normally have to block the pistons in place loosely as the come out to aid removal of the last pistons.

I got an adaptor made up so I could use my grease gun to push the (siezed) pistons out, various g clamps were used against the free pistons to stop them comming right out. Air line didn't budge mine..

Hi

the only way i was able to remove the pistons was thus,

rip off the rubber seals and using 2 screwdrivers on opposite sides-lever the piston out with the screwdrivers located in the seal groove.

Using air just had no impact....even tapping the caliper whilst applying air pressure-nothing.

I made no damage to the groove or piston...they actually came out quite easily.

Just thought i'd share that with you all.

Cheers
