Stripping 4 pots

[Stoffa]

anyone got any trick to popping the pistons out of after market calipers, mine have smooth titanium pistons so dont want to damage them, was using an air compressor but as soon as one pops out you lose all pressure. I was using bits of wood to try to get them almost all the way out but using the wood to stop them just before they pop, just a bit tricky

I use a pair of reverse pliers on the internal cup and pull and twist them out ( works well on Toyota 4 pots )

i think i used the air comp and used some thing to stop the pistons from completely coming out so you get atleast two of the pistons almost out then i used pliers to wiggle them the rest of way using the groove that the boot goes into. i think you can only get one side out the other has to be completely wiggled out, take your time and carefulness you shouldnt damage them. i think i used pliers otherwise i used a flathead screw driver in that groove carefully working all sides so it comes out evenly without too much force. but i suppose when the two pistons pops out using the compresser and you find a way to block those holes so that you can put enough pressure to pop the otherside out then that would be easier, i suppose somebody will know the proper way or easier way of doing it i did it on the 4pot subaru calipers.

do it over a nice soft old cuishon to catch the piston if you accidently drop one the cuishon will hopefully catch it and protect.

crap old thread you probably have sorted it now.

It is sorted, but they're not your normal 4 pots, they are proper racing style ones with internal dust seals and no grooves in the pistons and are made from bakelite (plastic) so you cant use pliers.

I've since been told the easiest way is to bash the caliper on a piece of wood, noisey as hell but it jars them out eventually.

Hhehee I have baker lite pistons in the brakes fitted to my trailer ( surprisingly almost all GOOD trailer brakes use them as they dont corrode )
