hi

ive just taken my 4pots to bits as i thought the pistons were sticky.
got one caliper off and removed pads and seals used flat head screw driver and i can move all 4, did the same on the other side, but i cud only move 1 piston, ive tried and tried to get the other 3 out snapped the end of my flat head screw driver. ive sprayed aload of WD40 to try and free them up.

so my question is, do i persist with another screwdriver or is there an easier way?

thanks for any advice

Just for the future then as you've seem to have done it, would be to use two medium size screwdrivers levering at 180 degrees to each other on the piston.

Using one screwdriver tilts the piston and given the tight tolerances, jams the piston even more.

 

The easiest thing to do is remove the pads while the caliper is in place and pump the pedal to get them out , if some of the pistons move easily you will have to put something in betwen the disc and piston to stop it popping out all together.
You can damage the caliper body at the lip of the bore if you lever a screwdrive against it

thanks people.

i phoned you earlier Ian, ordered the seal kits and hoses.

think i manage to get them out without damaging the caliper, will have a closer look in the morning.

what a pain in the ****, just been cleaning up the pistons, wishing i never started, but if it saves money then its worth a try.

what pads and disks would you recommend, as i have standard ones in at the mo.

i do fast road and ocassional track time, this being the reason i started doing the refurb. i had a serious spongey pedal, and cud feel the car slowing down a bit too quickly when coasting.
