Re: toyota camry 1994 wide body 2.2
There are two rubbers fitted to each of the caliper pistons.The outer one is a dust cover and the inner is the seal.... i you've removed the inner, you'll have to refit very carefully, not causing any damage....Lubricate with rubber grease and open the bleed nipple....push it in gently....The dust cover fits over the caliper housing and tapers outwards to fit the piston....

calipers are a toyota only dealer part unlike a ford with bendix or bosch brakes so as its a dealer then the sky is the limit ,strip and clean the fit new seals and make sure the seal path in the caliper body it well clean and they will work just like new.
The Camry brake system is very simple and easy to work with
Raise and support the car safely and remove the front wheel.
Undo the two bolts that hold the brake piston to the caliper. These are the two bolts toward the front. Remove and support the piston in a manner that does not place any strain on the brake line. For example, you can use a length of string to hang the piston from the strut spring.
With the piston out of the way, undo the two remaining bolts closer to the axle, that hold the brake caliper to the knuckle. Remove the caliper.
The old pads will slide out of the caliper. Note how they fit in place before removing them, so you can place the new ones the same way. Remove the shims from the back of each pad and place them on the back of the new pads.
Slide the new pads into the caliper.
Bolt the caliper onto the knuckle.
Use a clamp or a piston expander to push the piston back so it will fit over the new pads. Take care while doing this that you do not overflow the brake fluid in the master cylinder reservoir.
Put the piston back in place over the pads and bolt it onto the caliper.
Make sure all bolts are torqued to spec.
When replacing the pads, remove and inspect the rotors. If necessary, have them turned or replace them.
Also, inspect the calipers and make sure the spring arms move freely. Inspect the caliper hardware (clips and springs) and replace if necessary.
Inspect the pistons. If necessary, drain and refill the pistons with fresh brake fluid, and bleed the system.
With the brakes back in place, check that the brake pedal is firm or firms up after a few pumps at the
most. If not, you will need to figure out why.
Replace the wheel, lower the car, torque the lug nuts to spec, and you're done.
Brakes are an essential safety system of your car. Follow these instructions at your own risk. Refer to a complete service manual.
