How hard are the brakes pads on a 2005 honda Accord to change?

Front, easy; rear, can be more difficult. Rear brake pads are smaller and usually need replacing first. I recommend Honda OEM replacement pads. Aftermarket pads are not required to meet federal safety standards and are often compounded from different materials than OEM. Remember to remove the brake master cylinder reservoir cap, before using a disk brake pad spreader to compress each caliper piston. Lubricate caliper pins with silicone grease or Squeak Relief (silicone grease with moly). Obtain torque specs for your caliper bolts. Use Squeak Relief or Molykote M77 (included with Honda pads or ask for it) on any shims. Afterwards, it's best to bleed the brake system. Remember to adjust the emergency brake, when done.

Brake/Clutch fluid--I use Valvoline SynPower or ATE TYP 200 Brake Fluid. Change every 2 years. I use the fool-proof Brake Bleeder Economy One-Man, Cal-Van Tools, No. 247, brake bleeder for both. It costs $2.99 and has a one-way check valve built into it. Bleed in this sequence: RR, LF, LR, RF. Depress brake pedal (by hand) 12 times for rear brakes and 10 times for the front brakes. One quart or liter of fresh brake fluid will be more than sufficient.

Thank you. The front brakes were easy. How do I compress the back brake cyclinders? Do I need a special tool?

Possibly. Depending upon your brake caliper, you may be able to use the tab on the side of the brake pad to rotate the caliper piston clockwise into place in the cylinder, then align the cutout in the piston with the tab on the inner pad by turning the piston back. Otherwise, try a large pair of needle nose pliers or you will need a specialized tool (locknut wrench with extension bar). Lubricate the boot with rubber grease (or brake fluid), to avoid twisting the piston boot. If the piston boot is twisted, back it out so it sits properly.
