Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Use a caliper tool to compress the caliper piston.
3. Remove the caliper mounting bolts using a socket set.
4. Carefully lift the caliper away and support it without stressing the brake line.
5. Remove old brake pads from the caliper bracket.
6. Install new brake pads, ensuring they are correctly aligned.
7. Reattach the caliper and torque the bolts to manufacturer specifications (typically 25-30 ft-lbs).

3. Check and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir.
2. Inspect the fluid level; if low, clean the reservoir cap and add the correct brake fluid type (usually DOT 4).
3. Replace the reservoir cap securely.

4. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines for cracks, corrosion, or leaks.
2. If damage is found, use a line cutter and flare tool to replace the affected section of the line.
3. Ensure all connections are tightened and leak-free.

5. Reconnect Battery

Reconnect the battery terminal and ensure it is secure.
