There’s no need to pay a repair shop big money for new brakes. Most cars have brake pads that are easy to replace. With simple tools and a little time, you can save hundreds of dollars doing it yourself. Follow these easy steps and you can replace your own brake pads at home. 

What You’ll Need:

  • lug wrench
  • c-clamp
  • open end / adjustable wrench (depending on your car)
  • Allen wrenches (depending on your car)
  • hammer
  • small bungee cord

Preparation

Be sure you’ve got everything ready to go before you remove your old brake pads. Most important, be sure safety is at the forefront of your mind. You’ll be taking the wheel off, so have your car jacked up and resting securely on jack stands. Go ahead and break the lugs before you jack the vehicle up. It’s much easier and safer to break the lugs with the wheel on the ground.

Never work on a car that is supported by a jack only! Unless you turn green and your clothes tear themselves to pieces when you get mad, there is no part of your person that can hold a car in the air if the jack slips.


You may need to replace your brake discs, depending on the amount of wear they have.

Remove the Wheel

You broke the lugs while the car was still on the ground, so they should be pretty easy to remove. Remove them from the bottom up, leaving the top lug nut to be removed last. This keeps the wheel in one place while you remove lugs, and makes it easier to safely catch the wheel once you remove the last nut. You can’t replace brake pads with the wheel on.

If you remove the lugs and still can’t get the wheel off, try this stuck wheel trick.


Unbolt the Caliper


Remove the two bolts which hold the brake caliper.

On most cars, the next step is to remove the brake caliper so the brake pads will slide out through the top. On a few cars, the pads will come out without removing the caliper, but this is not common. You’ll see the brake caliper in the 12 o’clock position just above the lug bolts, at the top of the brake disc.

On the back of the caliper, you’ll find a bolt on either side. It will either be a hex bolt or an Allen bolt. Remove these two bolts and put them aside.

Hold the caliper from the top and pull upward, wiggling it around to loosen it up. If it’s stubborn, give it a few taps (taps, not Hank Aaron swings) upward to loosen it. Pull it up and slightly away, being sure not to put any stress on the brake line (the black hose that’s still connected).


If there is a place to safely set the caliper back there, do it. If not, you’ll need to take your bungee cord and hang the caliper from something. The coil spring is a good spot. Don’t let the caliper hang by the brake line, as it can cause damage and lead to brake failure.

Remove the Old Brake Pads


The old brake pads will slide right out.

Before you pull out the old brake pads, take a second to observe how everything is installed. If there are little metal clips around the brake pads, note their positioning so you can get it right when you put things back together. Better yet, take a digital picture of the whole assembly.

With the caliper out of the way, the brake pads should slide right out. However, you may need to coax them out with a little tap of the hammer to loosen them up. If your car has little metal tabs holding onto the brake pads, put them to the side because you’ll need them later. Put the new pads in the slots with any metal clips you removed.

While you’re here, it’s a good idea to inspect your brake discs.


Go ahead and slide the new pads into place now, making sure you don’t forget any of the metal retaining clips you removed earlier.

Compressing the Brake Piston


Slowly compress the brake piston.

As your brake pads wear out, the caliper adjusts itself, so you will have strong brakes throughout the life of the pads. If you look at the inside of the caliper, you’ll see a round piston. This is what pushes on the brake pads from the back. The problem is, the piston has adjusted itself to match your worn-out pads. Trying to get it over the new pads is like parking a Cadillac in New York City. You can do it, but the damage level will be high. Instead of destroying your new pads, push the piston back to the starting point.

Take the c-clamp and place the end with the screw on it against the ​piston. Place the other end of the clamp on the back of the caliper assembly. Now slowly tighten the clamp until the piston has moved far enough in so that you can easily plop the caliper assembly over the new pads.

Re-Install the Brake Caliper


Your new brake pads are ready to stop!.

With the piston compressed, you should be able to easily slide the caliper assembly over the new pads. Once you have the caliper in place, replace the bolts you removed and tighten them. Press the brake pedal a few times to make sure you have solid brake pressure. The first pump or two will be soft as the piston finds its new starting point on the back of the pad.

Put your wheel back on, being sure to tighten all of the lug bolts. Now double-check your lug bolts.

You’re done! Feels good, right?
