Common problem with the FJ front brake calipers is them seizing. The cause is down to corrision behind the seals which make the seal grip the brake piston so causing seizing.
The pistons should be easily be pushed in with finger pressure, if you find this is not the case then the answer is to strip the caliper down. You must replace seals if the caliper is dismantled.
This is a set of 4 wiper seals and 4 pressure seals, this does one caliper.
Also note that the seal which is between the two halfs of the caliper is not available, so be carefull not to loose or damage this seal.
TIP; When replacing seals use the brake pressure to push the pistons out as far as you can on all pistons before disconnecting fron the brake line. This will make it easier to blow the pistons out the last few mm's.
