How to replace brake pads (Simple manual for front brakes)

Replacing your brake pads is standard maintenance for any vehicle and the wear of your brake pads should be checked regularly to ensure proper operation and safety. If you are concerned about changing your brakes please consult a professional, although many mechanically inclined individuals are able to easily replace their own brake pads. Changing brake pads may take a first timer up to 3 hours and for some applications may require specialised tools including brake caliper reset tools. Some calipers may need to be turned simultaneously while being compressed.

Step 1:

Ensure you have the correct tools (caliper reset tool, needle nose pliers, socket set, tire iron, jack), parts, and fluids required for your vehicle.

Step 2:

Secure your vehicle ensuring that it will not roll or move when jacking.

Step 3:

Choose one side (front driver's side, front passenger's side, rear driver's side, or rear passenger side) and loosen the wheels lug nuts before lifting the vehicle. 
HINT: Working on one side at a time ensures that you can use the other side for reference if you get lost, and will also allow you to test one side for problems before working on the other.

Step 4:

Double check that your e-brake is on (if working on the front disc brakes) and ensure your vehicle is secured. Safely jack the vehicle and remove the wheels lug nuts and tire from the working side.

Step 5:

Inspect your brake components for wear, rust, and/or cracks (brake rotor, brake pads, brake caliper, caliper mount and brake flex hose). If you find additional worn parts you should replace these at the same time.

Step 6:

Find and remove the caliper bolts. There are generally two caliper bolts securing the caliper. These can be identified easily by the rubber protective sleeves which partially cover the bolt.

Step 7:

Lift the brake caliper out of the way and safely rest or secure the caliper ensuring not to damage the brake hose. Brake hoses may become brittle over time. Inspect for wear and replace if applicable.

Step 8:

 Remove the brake pads, ensuring to check for anti-rattle hardware that will be re-used. Place your old parts neatly aside.

Step 9:

Inspect the rotor for wear (groves or warping). If the rotor shows signs of wear replace with a new rotor. Inexpensive rotors are available and turning of rotors may be done at a local shop although it is recommended that new rotors be purchased. To replace the rotor: remove the caliper mount and caliper release screw if applicable. Your caliper may become stuck. A light hammer tap or screw driver may help you to remove the caliper. Lubricants can also help if rust has formed between the bearing hub and rotor. Clean and inspect the area and studs. Replace if necessary. A new rotor can be mounted and secured in place after using brake cleaner to remove residue and oils from the rotor.

Step 10:

 Prepare a bucket to catch excess brake fluids and loosen the fluid release nipple on the caliper. It is recommended that fluids be released on all anti-lock brake vehicles. Small rubber particles may over time develop in your brake lines and should not be pushed back up the brake lines. These particles can disturb anti-lock braking system sensors.

Step 11:

Push back the caliper using a c-clamp or by hand. The caliper should move fairly easily without brake fluid pressure although a c-clamp may make it easier. If you are using a c-clamp be sure to protect the end of the caliper when compressing. Compress fully.

Step 12:

 Install your new brakes and ensure that they are seated correctly in the caliper mount. If applicable re-install your anti-rattle sleeves.

Step 13:

Lubricate the caliper sleeves and re-install the brake caliper. Ensure that the caliper moves freely and doesn't bind.

Step 14:

Bleed the brake system to ensure that any trapped air is removed. Check you manufacturer's specifications for full instructions on how to properly bleed your vehicles brakes.

Step 15:

Ensure the brake pedal has correct back pressure and re-install tire.

Step 16:

Repeat for other side.

Notes:

This is meant as an example of how to replace your brake pads. Consult an expert for advice prior to attempting any replacement. 

New brake pads may require time to settle and will be less efficient until worn in. Before driving the vehicle ensure that your brakes operate correctly.
