DIY Brake Service: How to Change Brake Pads?

Did you ever feel that your vehicle stopping distance has increased at the time of braking?

Have you heard the wheels scream or make a strange noise when you step on the brake pedal?

It is most likely that the front or rear brake pads have worn and it is time to change your brake pads. It is not a simple operation, but if you follow the steps shown below you will know how to change brake pads. There is a good chance that you will save about $100 or $200 dollars (USD) that you will have to pay in a mechanical workshop.

Why Do I Need To Change The Brake Pads?

The brake pads are responsible for creating friction with the brake disc and the more you step on the pedal the more you create that friction until you stop the vehicle completely.

The brake pads are essential elements to have a proper braking mechanism and with time they will gradually wear out and get worse. A brake pad set in poor condition makes little friction on the disc and this increases the stopping time and distance. This cannot be allowed because at the time of an emergency they can fail completely which can lead to a fatal collision or a car accident.

Tools Required To Change Brake Pads

Tools that are needed to change brake pads are:

  1. Hydraulic Jack: To lift the vehicle and be able to Remove the wheel.
  2. Cross Wrench: To loosen and remove the screws of the wheel.
  3. Allen Key: To loosen and remove the screws that can not be removed with the Cross Wrench.
  4. Flat screwdriver: To lever and remove the brake pads from the brake disc.

How to Change the Brake Pads?

Autowagons will show you how to Change the brake pads in 7 steps given below:

1) Turn The Wheels

Turn the direction of your vehicle towards the wheel whose brake pads you want to change. This means if you need to change the one on the right, turn the steering wheel to the right and if it is on the left wheel, turn the steering wheel to the left. Then grab the cross wrench and loosen the screws of your tire without removing them.

2) Lift The Vehicle and Remove The Tire

Grab the hydraulic jack and lift the vehicle.

Remove the screws with the cross Wrench and then take out the wheel so that you can access the brake system.

3) Remove The Brake Pads

After removing the wheel, you will have front brake and disc pads. Use the Allen wrench to loosen and remove the screws that hold it. Then grasp the screwdriver and lever the end of the screwdriver into the pads and with the edges of the disk, never on the surface of the contact.

4) Install The New Brake Pads

The new brake pads have to be installed by applying some pressure. You just have to introduce a little pressure on the side so that they enter and hook into the metallic top plate. When they are inside, apply some force and adjust the brake piston in order to fit them perfectly. Then hold the Allen Wrench and screw them again.

5) Mount the Wheel Back

After verifying that everything is fine, assemble the wheel again. Place the screws on the bolts and use the cross wrench to tighten them, making sure nothing is loose.

6) Repeat The Same For Other Wheel

When you finish with the first wheel, follow the same steps with the rest of the wheels. In case you only want to replace the front or rear pads you will only repeat the process once.

7) Pump the Brake System

As a precaution it is important to pump the brake system, this is done by pressing the pedal fully and progressively several times. In this way, the brake piston closes the pad to the disc and leaves it in its correct place so that it works in perfect condition.

To test the new brake pads it is recommended to roll the first 96 miles (100 kilometers) braking gently and not abruptly. Any abrupt braking will shorten the life of the brake pads.
