Hello and welcome to justanswer.com
Are you replacing the front or rear brake pads? Are you also replacing the rotors?
Replacing the brake pads and rotors is not that difficult. I will attach the Honda procedures but also give you a desription. To remove the calipers remove the 14mm bolts. Remove the pads then the 17mm bolts holding the anchors to the knuckles. You will need to remove the phillips screws holding the rotor to the hub. These screws are usually tight so an impact driver will help to remove them. Once removed the rotor will either need to be hit off with a hammer or screw in two 8 by 1.25mm bolts into the rotor which will pop it off the hub. You will need a C clamp or equivalent to push back the caliper pistons. I recommend that you crack open the bleeder screw so you do not push the fluid back into the master cylinder. Once reassembled with an assistant helping you bleed the brakes. Pump the brakes til you get a good pedal. Then starting with the passenger rear, driver rear, passenger front, driver front have an assistant pump the brakes then hold down the pedal. Then you crack open the bleeder. Do this til you get a steady stream of clean fluid to each wheel.
Your van uses a seperate parking brake cable drum setup. Here is the adjusment procedure.
It's pretty much the same. Once the caliper and anchor bracket is removed unscrew the phillips screws then use the bolts to pull the rotor off the hub.
I sent you the adjustment and bleeding procedures in a previous post.
