Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
If the brake fluid level is low, clean the area around the cap to prevent contamination.
Use a funnel to add the appropriate type of brake fluid (DOT 3 or DOT 4, depending on the vehicle specification) to the master cylinder reservoir to the correct level.

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line wrench
Inspect all brake lines and hoses for signs of wear, cracks, or leaks.
If any lines are damaged or leaking, replace them with OEM or high-quality aftermarket parts.
Ensure all connections are tight and leak-free.

4. Replace Brake Pads and Rotors (if necessary)

Tools Required: Jack, jack stands, socket set, brake caliper tool
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Remove the caliper bolts and slide the caliper off the rotor.
Check the brake pads for thickness; if they are below the minimum specification (usually 3mm), replace them.
Inspect the rotors; if they are scored or worn beyond the minimum thickness, replace them.
Reinstall new pads and rotors, ensuring to torque bolts to the manufacturer's specifications.

5. Bleed the Brakes

Tools Required: Brake bleeder kit, clear tubing, container
Start at the furthest wheel from the master cylinder (usually the passenger rear).
Connect the clear tubing to the bleeder valve and place the other end in a container.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow fluid and air to escape, then close it before your assistant releases the pedal.
Repeat until no air bubbles appear in the fluid. Move to the next wheel in the correct sequence (passenger front, driver rear, driver front).
Check the brake fluid level frequently and refill as needed.
