Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags
Remove the master cylinder reservoir cap and inspect fluid condition.
If fluid is dirty or low, use a funnel to refill with the appropriate brake fluid (DOT 3 or DOT 4).
Clean any spills and replace the cap securely.

3. Inspect and Replace Brake Components

Tools Required: Wrench set, socket set, jack stands, brake cleaner, new brake pads, rotors (if necessary)
Raise the vehicle and remove the wheel to access the brake components.
Inspect brake pads for thickness; if less than 3mm, replace them.
Check rotors for warping or scoring; replace if necessary.
Remove the caliper bolts, lift the caliper, and remove the old pads.
Install new pads and reassemble the caliper. Torque bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Replace the Master Cylinder (if necessary)

Tools Required: Wrench set, brake line wrench, new master cylinder, brake fluid
Disconnect brake lines from the master cylinder using a brake line wrench to avoid stripping the fittings.
Remove the master cylinder mounting bolts and take out the master cylinder.
Install the new master cylinder and secure it with mounting bolts to the manufacturer’s specifications.
Reconnect the brake lines, ensuring all connections are tight.

5. Bleed the Brakes

Tools Required: Brake bleeder kit, fresh brake fluid
Start with the wheel farthest from the master cylinder (usually the passenger rear).
Attach the bleeder kit to the bleeder valve on the caliper.
Pump the brake pedal several times, then hold it down as you open the bleeder valve to release air and fluid.
Close the valve and repeat until no air bubbles appear.
Move to the next wheel and repeat the process in the correct order (passenger rear, driver rear, passenger front, driver front).
