Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts from the wheel.
Take off the wheel to access the brake assembly.

4. Inspect and Remove Caliper

Inspect the brake caliper for any signs of wear, damage, or leaks.
Remove the caliper bolts using a socket set (typically 12-15 ft-lbs torque).
Carefully slide the caliper off the brake rotor.
Support the caliper with a bungee cord or hang it to prevent stress on the brake line.

5. Replace or Repair

If the caliper is leaking or damaged, install a new brake caliper.
- Remove the old caliper by disconnecting the brake line with a flare wrench.
- Install the new caliper and tighten the brake line securely.
If repairing, replace any worn seals and lubricate with brake grease.

6. Reassemble

Slide the caliper back onto the rotor and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.

7. Test

Press the brake pedal several times to seat the caliper and pads.
Test drive the vehicle to ensure proper braking function.
