Solution

1. Preparation

Gather tools and parts needed:
- Brake fluid
- Wrenches (various sizes)
- Brake bleeder kit
- Torque wrench
Park the car on a level surface and engage the parking brake.

2. Inspect and Repair Leaks

Check the Master Cylinder:
- Remove the master cylinder cover and inspect for fluid level and leaks.
- If leaks are found, replace the master cylinder.
Check Brake Lines and Hoses:
- Inspect all brake lines and hoses for signs of wear or damage.
- Replace any damaged lines or hoses using appropriate fittings.

3. Bleed the Brake System

Locate Bleed Valves:
- Identify the bleed valves on each brake caliper.
Using Bleeder Kit:
- Attach the bleeder kit to the first caliper (start with the farthest from the master cylinder).
- Have an assistant press the brake pedal while you open the bleed valve to allow air and old fluid to escape.
- Close the valve before the assistant releases the pedal.
- Repeat until no air bubbles are seen in the fluid.
Repeat for All Calipers:
- Move to the next caliper in the order: farthest to nearest from the master cylinder.
Refill Master Cylinder:
- Ensure the master cylinder is filled with fresh brake fluid throughout the bleeding process.

4. Replace Brake Pads (If Necessary)

Remove Wheels:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel to access the brake caliper.
Remove Caliper:
- Unbolt the caliper from the bracket and slide it off the rotor.
Replace Brake Pads:
- Remove the old pads and install the new pads.
- Reinstall the caliper and torque the bolts to manufacturer specifications.
