Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery to prevent accidental braking system activation during repairs.

2. Inspect and Repair Brake Fluid Leak

Step 1: Locate the source of the brake fluid leak by inspecting brake lines, calipers, and connections.
Step 2: If a leak is found in the brake lines or connections, replace the damaged section with new lines or fittings.
Step 3: If the leak is from a caliper, remove the caliper and replace the sealing components or the entire caliper if damaged.
Tools Required: Wrench set, brake line cutting tool (if necessary), brake fluid.

3. Replace Brake Pads and Rotors (if necessary)

Step 1: Remove the wheel to access the brake assembly.
Step 2: Remove the caliper bolts using a socket set and carefully detach the caliper from the rotor.
Step 3: Remove old brake pads from the caliper bracket.
Step 4: Inspect the rotor for wear; replace if the thickness is below the manufacturer’s specifications or if there are deep grooves.
Step 5: Install new brake pads and reassemble the caliper.
Tools Required: Socket set, torque wrench, brake cleaner, new brake pads, new rotors (if needed).

4. Check Brake Booster

Step 1: Inspect the vacuum hose connected to the brake booster for cracks or disconnections.
Step 2: Test the brake booster operation by pressing the brake pedal before starting the engine; it should feel firm, then soften when the engine starts.
Step 3: Replace the brake booster if it fails the test.
Tools Required: Wrench set.
