You can lever with a big screwdriver,
use large waterpump pliers
or get a spreader tool for a few quid from machine mart.

Thing to be careful off is not pushing the fluid back into the master cylinder....

Open the bleed nipple 1st to expel the fluid, or you take the risk of inverting the seal.  Then bleed as normal afterwards.

I did this and used a small G clamp  :y

If you open the bleed nipple and then slowly push the pads appart,that should remove enough fluid to avoid problems with seals then?also would the system still require bleeding as you would only need to top up the master cylinder for what has been lost...does that sound correct ?
Just wondering what the easiest tools was to use for getting new pads back over discs when renewing.

I would bleed anyway while your at it, fresh fluid isnt going to hurt.

the tool I use is this :

Sure it was much cheaper when I bought it, but struggled that much the 1st time, didnt want to struggle again.

Cheers Jimbob.....that looks a decent bit of kit and alot easier than a couple of tyre levers...question about needing to bleed was just curious as couldn,t see why as system not opened to allow air in ..but agree would do anyway.

suppose you may get a little air in, you could clamp the hoses to help, but i would bleed while your at it, for the sake of £5 on fluid

I always bleed a little fluid through using an eezibleed after pad replacement. TBH, brake fluid is normally due a change (every 2 years) by the time the pads are done anyway.

In theory opening the bleed nipple won't let any air in if you apply steady pressure to the piston but I'd rather close it with pressure behind it to make sure.

easy job, hth
should say if these where brand new shiney calipers i would not apply the grip jaws directly to the piston,use a rag or an old brake pad or sumat, but due to the level of corrosion and muck i wasnt too bothered tbh

When I changed my brake pads, I used my old brake pad and a G-Clamp to push the piston back, did it fairly slowly to limit possibility of damaging the seals.

Vitrtually as in the photo, but I put a small piece of plywood between the jaws and the caliper piston, to avoid damage and spread the force, gentle pressure and the piston slides in sweetly  :)
