Having bought new disks and pads all round, I decided to fit them today as my brakes were **** poor since I drove the car home from blighty.
Rears changed fine (bar wrong sized disc but was ok as the disk was barely used, just a little rusted from dodgey pads)
Got to the front passenger side to do the 4pot and noticed three of the pistons wouldnt wind back an further so pumped the pedal (after putting the lid on the reservoir first) and only one of them came fully out, the other three are still where they started. I am about to take the caliper apart and see if I can get the pistons free'd up and check the seals.
Does anyone have any guides on how best to do this?



Pardon the usual rust on the rear, its getting wire brushed and panted before Im finished.

Jam the one that moves. I found that the pistons will push out in order. so if u jam that top one then the one underneath or on the other side might move.

Should be able to do this to loosen them all up. so its usable before refurb.

I got 3 of the pistons moving and sliding (two were quite stiff) but one is sat a mm or two out but isnt budging at all.

looks like its refurb time them. I believe Godspeed can provide exchange refurb 4pots. might be worth a look if you want to save some hassle.

Hi
If you leave the calipers still conected on the car you will get the pistons out fairly easy , but it will take 2 of you , if 3 of the pistons are now moving , push these 3 back in and put some thing between the piston and disc to stop them popping out , the 2 on the same side , put the pad back in , the pistons thats stuck , fit the pad in sideways so its only stopping the moving piston from coming out , you keep an eye on it while you get someone to pump the pedal , it will move , you can take the pads out and put something thinner inbetween the pistons and discs to get them out as far as you can without them comming all the way out , remove the caliper and then strip it down.

If you need any parts , I can supply you stainless steel pistons that will never rust for £20 each , or a set of 8 for £100 , and seal kits are £19 per caliper.

I can also supply you fully reconditioned calipers any colour you want for £195 a pair exchange

Ian have you got any pics of your work on the exchange calipers, maybe going down this route unless I buy a new 8 pot brake set.
