Brake Caliper Cleaning
Every year I remove the calipers and clean them.
The products you will need for this job are:
Tools to remove the calipers, ie torque wrench, pliers etc.
Wire to hang the calipers in place if you are not holding them, so you do not stress the brake lines.
fine emery cloth

This is just a basic preventive maintenance task. I'm not talking about dismantling the calipers and removing the pistons and seals.
What you do is remove the calipers and brake pads by the method the manual suggests. Remember where everything goes.
Spray the brake cleaner around the pistons and seals
Use your tooth brush to scrub them clean
If there are any burrs on the floating pins sand them with a fine emery cloth.
Once everything is clean put copper grease on the floating pins and on the back of the pads near the pistons. This stops squealing and reduces metal to metal friction. Do not get grease on the discs or friction material of pads. Then reasemble.
Remove the other caliper if you do not understand how it goes back together for referance.
Retourque bolts to manual specs with torque wrench.
Always refer to your shop manual for correct procedures
