Diagnostic Steps

Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Brake line wrench
- Socket set
- Torque wrench
- Brake cleaner
- C-clamp or brake caliper tool
- New brake fluid
Safety Warnings:
- Ensure the vehicle is on a level surface and secured with jack stands.
- Wear safety goggles and gloves.

2. Remove Wheel

Use the lug wrench to loosen and remove the lug nuts from the wheel.
Lift the vehicle using the jack and secure it on jack stands.
Remove the wheel to access the brake caliper.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the brake rotor. Do not let the caliper hang by the brake line; use a bungee cord or strap to secure it to the suspension.
Disconnect the brake line from the caliper using a brake line wrench. Be prepared for some brake fluid to leak out.

4. Install New Brake Caliper

Compare the old caliper with the new one to ensure they are identical.
Attach the brake line to the new caliper and tighten it securely.
Slide the new caliper onto the rotor and align it with the mounting bracket.
Install and torque the caliper mounting bolts to the manufacturer's specifications (typically around 25-30 ft-lbs, but check your specific model).

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and onto the ground.
Tighten the lug nuts in a crisscross pattern to the manufacturer's specifications (usually around 100-110 ft-lbs).

6. Bleed Brake System

Using a helper, pump the brake pedal several times to build pressure.
Starting with the caliper farthest from the master cylinder, open the bleeder valve to release air and fluid until clear fluid flows out. Close the valve and repeat for the other calipers in order.
Check and top off the brake fluid reservoir as necessary.
