Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, socket set, C-clamp or brake caliper tool, brake cleaner, rags, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Lift Vehicle and Remove Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheel using a lug wrench.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or hang it to avoid straining the brake line.
If the caliper is stuck, gently tap it with a rubber mallet to loosen.

4. Inspect and Replace

Check the caliper for leaks or damage. If damaged, it must be replaced.
Inspect the caliper piston for corrosion or seizing. If necessary, replace the caliper.
Replace the brake pads if they are worn down or unevenly worn. Ensure the new pads are compatible with the caliper.

5. Reassemble and Bleed Brakes

Reinstall the caliper over the new pads and rotor, securing it with the mounting bolts. Torque the bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing if necessary.
Reconnect the brake line if it was removed, ensuring it is tight and leak-free.
Bleed the brake system to remove any air from the lines. Start from the furthest caliper from the master cylinder and work towards it.

6. Final Steps

Reinstall the wheel and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).
Reconnect the negative battery terminal.
