Taking the time to replace the brake pads on your Toyota Yaris will save you hundreds of dollars and also give you the satisfaction of repairing your own vehicle. When replacing the brake pads, also replace the rotors so the new pads have an even surface to push against while braking. Replacing the brake pads and rotors will increase the performance and longevity of the brakes.
Lift the Toyota Yaris with the jack and place the vehicle on jack stands.
Remove the wheels with a lug wrench and set them aside.
Remove the caliper with a ratchet and use a bungee cord to hang the caliper. Do not let the caliper hang from the brake hose as the hose might break and cause fluid to leak.
Remove the brake rotor from the hub. The rotor might require force to be removed; if it does, use a hammer to hit the rotor in the centre, where the lug studs are located. Take care not to hit the studs.
Remove the new rotor from its packaging and use brake cleaner to remove the grease from the rotor. Grease is applied to the rotor in the factory to inhibit rust during storage.
Install the new rotor onto the hub.
Install the caliper bracket onto the steering knuckle. The knuckle is the component the strut and hub are attached to. Slide the brake pads into the caliper bracket.
Open the master cylinder reservoir so you don't break a seal while compressing the brake caliper. The master cylinder is located at the front right of the engine bay when you are looking at the front of the engine.
Compress the brake caliper with a C-clamp so that the caliper can fit over the new brake pads. Install the caliper by securing it to the brake caliper bracket with a ratchet.
A brake caliper compressor might work better than a C-clamp. A brake caliper compressor easily squeezes the piston into the caliper, much easier than using a C-clamp or adjustable pliers.
Wear safety glasses while working on your brakes.
