Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Remove the wheel using a lug wrench.
Inspect brake pads for thickness; replace if less than 3mm.
If replacement is necessary, unbolt the caliper assembly and slide off the caliper.
Remove the old brake pads and install new ones, ensuring they are correctly oriented.
Reattach the caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).

3. Replace Brake Rotors (if necessary)

Tools Required: Socket set, brake rotor removal tool (if rusted), torque wrench.
After removing the caliper, slide off the rotor.
Inspect the rotor for warping or scoring; if damaged, replace with new rotors.
Clean the hub surface and install the new rotor.
Reinstall the caliper and torque to manufacturer specifications.

4. Check and Refill Brake Fluid

Tools Required: Brake fluid tester (if applicable), funnel.
Check the brake fluid condition; if discolored or contaminated, flush the system.
Refill the master cylinder with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).

5. Test and Adjust Brake Booster

Tools Required: Vacuum pump (if testing).
Disconnect the vacuum line from the brake booster and connect a vacuum pump.
Apply vacuum and check for leaks; if the vacuum drops quickly, replace the brake booster.
