How do compress rear brake caliper pistons on Honda Accord 2010?

You need a big towel you won't mind losing, lots of shop rags and brake parts cleaner, a garbage bag, a long zip tie, and a small

• 3" will do it - C-clamp...in addition to the normal screwdrivers,

wrenches, pliers, etc. First, pop the hood, jack up the back of the car, support it on jackstands, and remove both wheels. Then remove the brake pads.

Now for the fun part. Go into the engine compartment. Wrap the towel around the bottom of your master cylinder, then put the bag around the towel. Remove the brake fluid cap, then wrap the bag around the whole thing and zip-tie it to the master cylinder. (You'll understand why in a second.)

Go back to the wheel and use the C-clamp to compress the rear brake caliper pistons. Do all the brake work you were going to on the back of your car.

The reason you did all the stuff with the towel and bag, is every time you compress the brake caliper pistons brake fluid will squirt out of the master cylinder. Since it dissolves paint you don't want it flying all over the place. So...now you can open the bag, carefully remove it, and use brake cleaner on rags to clean off the master cylinder and reservoir.
