Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Tools Required:

Jack and jack stands
Lug wrench
Brake caliper tool or C-clamp
Torque wrench
Brake cleaner
Pliers
Socket set
Brake fluid

2. Remove the Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle using a jack and support it with jack stands.
Remove the lug nuts and take off the wheel to access the caliper.

3. Remove the Caliper

Locate the caliper mounting bolts and remove them using a socket set.
Suspend the caliper using a bungee cord or rope to avoid stress on the brake line; do not let it hang freely.
Disconnect the brake line from the caliper using pliers, and be ready to catch any leaking brake fluid.

4. Inspect and Replace the Caliper

Inspect the old caliper for damage or malfunction.
If replacement is necessary, install the new caliper by reversing the removal process:
- Connect the brake line to the new caliper and tighten it securely.
- Ensure all seals are in place to prevent leaks.

5. Reinstall the Brake Pads

If the brake pads are worn, remove them and replace them with new ones.
Apply brake lubricant to the back of the pads and any sliding surfaces.
Reinstall the pads into the caliper.

6. Reinstall the Caliper and Wheel

Position the caliper over the new pads and secure it with mounting bolts, using a torque wrench to tighten to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the correct specifications.

7. Final Checks

Top up the brake fluid reservoir and bleed the brakes as needed to remove air from the system.
Test the brake pedal for firmness.
