2
Check for visible leaks in the brake lines, calipers, and hoses.
3
Inspect brake pads and rotors for wear and damage.
4

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety goggles and gloves.

Tools Required:

Brake bleeder kit
Wrench set
Socket set
Torque wrench
Jack and jack stands
Brake fluid (DOT 4 or as specified by the manufacturer)

2. Inspect and Replace Brake Components

Check Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; replace if less than 3mm.
- Inspect rotors for warping or scoring; replace if necessary.
Replace Brake Pads (if needed):
- Remove the caliper bolts with a socket.
- Lift the caliper off the rotor and secure it (do not hang by the brake line).
- Remove old pads and install new pads in the caliper bracket.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).

3. Bleed the Brake System

Prepare for Bleeding:
- Start at the wheel farthest from the master cylinder, typically the rear right.
- Attach the brake bleeder kit to the bleeder screw on the caliper.
Bleed the Brakes:
- With an assistant, have them pump the brake pedal several times and hold it.
- Open the bleeder screw to allow fluid and air to escape; close it before your assistant releases the pedal.
- Repeat until no air bubbles are visible in the fluid.
- Move to the next wheel (rear left, front right, front left) and repeat the process.

4. Final Checks

Refill the master cylinder reservoir with brake fluid to the proper level.
Reinstall wheels, torque lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
Lower the vehicle from the jack stands.
