Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
- Remove the rear wheels using a socket set.
- Inspect brake pads for thickness; replace if worn below manufacturer specifications.
- Check the rotors for warping or scoring; replace if necessary.
Caliper Inspection:
- Remove the caliper bolts with a socket set.
- Inspect caliper slide pins for lubrication and movement; apply high-temperature grease if needed.
- Check for any signs of fluid leaks from the caliper; replace if leaking.

3. Check Brake Lines and Fluid

Brake Line Inspection:
- Inspect all brake lines for corrosion, leaks, or damage.
- Replace any damaged brake lines with OEM replacement parts.
Brake Fluid Replacement:
- Flush the brake fluid system using a brake bleeder kit.
- Use DOT 3 or DOT 4 brake fluid as specified in the owner’s manual.

4. Test and Adjust Brake System

Brake System Test:
- Reconnect the negative battery terminal.
- Start the vehicle and pump the brake pedal to build pressure.
- Test drive the vehicle at low speeds to ensure brakes engage smoothly without locking up.
Electronic Brake Control Check:
- If equipped with EBD, use a diagnostic tool to ensure all electronic systems are functioning correctly.
