Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Remove the wheel to access the brake caliper.

Tools Required:

Jack and jack stands
Socket set
Brake cleaner
Torque wrench
C-Clamp or brake caliper tool
Brake fluid

2. Remove the Caliper

Step 1: Use the socket set to remove the caliper mounting bolts.
Step 2: Carefully slide the caliper off the brake rotor. Support it with a bungee cord or similar to avoid straining the brake line.
Step 3: Disconnect the brake line from the caliper using the appropriate size wrench. Allow any excess brake fluid to drain into a container.

3. Inspect and Replace Components

Step 1: Inspect the caliper piston for scoring or damage. If damaged, replace the caliper.
Step 2: Check the caliper slides for corrosion or dirt. Clean them with brake cleaner and a wire brush if necessary.
Step 3: Replace brake pads if they are worn unevenly or below the minimum thickness.

4. Install the New or Repaired Caliper

Step 1: If replacing the caliper, install the new caliper onto the bracket and tighten the mounting bolts to the manufacturer’s specified torque value.
Step 2: Reconnect the brake line to the caliper and ensure it is snug but not overtightened.
Step 3: Use a C-clamp to compress the caliper piston back into the caliper housing if reusing the caliper.

5. Final Assembly

Step 1: Reinstall the wheel and tighten lug nuts to the specified torque.
Step 2: Lower the vehicle from the jack stands.
Step 3: Pump the brake pedal several times to ensure the caliper piston seats properly and to restore brake pressure.
