Retracting Caliper Pistons, How to? Options

[Vince-Noir]

My new rear discs are on and the calipers are off waiting for me to retract the pistons before i replace the pads, but i have no idea how to retract the pistons on my 98 GT (3SGE). In fact they look fully extended!

Can anyone tell me how to do this please?

Many thanks

Ok took the GT into my local trusted garage yesterday arvo and their initial reactions were that awful sharp, rapid, inhaling through the teeth sound! First of all the mechanic thought that it was going to be a job of replacing the seals in the calipers and having to purchase a seal kit from Toyota to do this... We also realised that i had somehow got the pistons basically all the way out (as they were free turning) he definitely thought i would not have got away without wrecking the seals when reinserting them. Did well so far didnt i?!

Anyway, as we discussed it further it would seem that i managed to get them back in gently enough so that i did not cause anymore leaking when fully re-assembled... so i may have got away with it - fingers crossed! What he did say tho, from the way i was putting the pistons back in is that i probably took some air back into the system, explaining the sponginess of the middle pedal! So all i theoretically need to do is perform a bleed from each of the rear calipers (showed me the coke bottle method so as not to further soil the driveway).

Also asked him about the condition of the brake fluid after having had the cap off for a couple of hours, both he and the mechanics from next door (toyota) said theres no problem... only if it had rained or something more drastic would it have ruined the fluid! Sounds interesting considering that previous posts about it made perfect sense...

Anyway, we shall see what happens
