Step 1: Gather materials

Materials:

  • new brake pads
  • brake disc lube (high temperature synthetic grease)
  • probably, new retainer pin spring clips

Tools:

  • floor jack or other jack
  • lug nut wrench
  • assorted screwdrivers and pliers

My two cents:

Brake pads come in several flavors, named (in order of increasing high-techiness):
1 organic -- old style asbestos
2 semi-metallic -- fitted to most new cars
3 metallic -- usually used on race cars
4 ceramic -- the New New Thing in brake pads

Since you're saving beaucoup $$$ by replacing your own pads, it certainly does not hurt to spend a few extra bucks for the next better pads than the factory pads.

For instance, in my case, my car (1997 Ford Escort LX wagon -- not-too-sexy!) was factory equipped with semi-metallic in front, and organic in rear. I bumped up to ceramic in front, for $18 more, and if I were to do the rear, I would probably fit semi-metallic.

Step 2: Raise car and remove road wheel

Using a floor jack or your car's emergency jack, raise the road wheel off the road.

Remove the road wheel to expose the disc and the brake caliper.

If you're doing front brakes, you may wish to turn your steering wheel to afford better access to the caliper.

XXXTRA SAFETY TIPS:
  • put car in gear
  • apply parking brake
  • chock wheels
  • stash road wheel UNDER the chassis while you're working on the brake. That way, if you have your head stuck in the fender well and your car falls off the jack (against all odds), the chassis will fall on the wheel, and hopefully your head won't be squished like an overripe cantaloupe.

Step 3: Remove retaining clips

At the back of the caliper, you'll find two complex-shaped little twisty spring clips. These springs hold the retaining pins in, which in turn hold the brake pads in.

Using needle nosed pliers and a flat blade screwdriver, remove these spring clips.

The ones on my car are broken, so the tangle doesn't make much sense in this photo. I'll add new photos when I get the new clips.

On a older Chevy I had, it had 2 side-by-side pistons, and you imagine what could happen if I tried to push only one in at a time.. A easy trick, take one of the old pads, and use it to press both at the same time with a C-Clamp. this way, they'll stay even, and not do the same as I saw someone else do, pressing just the inside edges of the two.. )( (YIKES! Bring in a new caliper!)

you should be using two stands at a time to lift the entire rear end up or the entire front end up. when you replace pads you should be replacing both of the back brakes or both the front brakes at a time if not all 4 at once. this is to produce even wear. Also you should take the caliper off when replacing the pads to inspect it for wear and damage also it makes the removing and installing of pads simpler. you don't want to use anything to pry against the rotor...."disc"....you could gouge it or crack it if it's old enough(perhaps a new rotor is necessary if you actually manage to crack it.) this is more important when you are compressing the piston to allow for the new pads. also with the caliper off it easier and safer to compress the piston by use of a c clamp.

Brake to be careful

Relying on a jack to support a vehicle during maintenance is totally hazardous. Unless you have a really wide wheel the the tire trick will fail in a deadly manner.

Use the jack only to raise and lower the vehicle. One the vehicle is raised place jack stands under a frame part and remove or lower the jack.

Even a little pressure with a metal device will damage a rotor surface. It doesn't take much. Large mouth pliers can be used to collapse the piston.

As others have said, the rotors need to be turned by an authorized brake specialist. The specialist will also assure that the finished rotor will meet the manufacturer's requirements for rotor thickness.

You failed to mention examining the brake system for wear and signs of leakage at the joints and at rubbing points in the brake lines. You should also install a rebuild kit on the piston. And as others have said, bleed the brake lines.

Brakes are life savers and their maintenance cannot be taken too seriously.

one more thing - there is such a thing as a pad spreader, and many auto parts stores will loan you one for free.

Oh, yeah - what he said about the hierarchy of usability of shop manuals. Factory-> Haynes, and then Chilton probably not worth the trouble. I would add that many public libraries have an excellent collection of factory shop manuals. Many has been the time when I couldn't figure something out, or wasn't confident about something, and I have found the answer in a factory shop manual at a library.
