Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line wrench, brake cleaner, rags
Sub-steps:
1. Identify the source of the leak by inspecting all brake lines, fittings, calipers, and the master cylinder.
2. If a leak is found in a brake line, replace the damaged section using the brake line wrench.
3. For calipers, replace any damaged seals or the entire caliper if necessary.
4. Clean the area with brake cleaner and ensure no residual fluid is present.

3. Replace Brake Fluid

Tools Required: Brake fluid funnel, turkey baster or syringe
Sub-steps:
1. Use a turkey baster or syringe to remove old brake fluid from the reservoir.
2. Refill with new brake fluid that meets the manufacturer’s specification (typically DOT 4 for Renault vehicles).
3. Ensure the reservoir is filled to the maximum mark.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder valves
Sub-steps:
1. Start at the furthest wheel from the master cylinder (usually the rear passenger side).
2. Attach the brake bleeder kit to the bleeder valve and open it.
3. Have an assistant press the brake pedal several times and hold it down.
4. Close the bleeder valve, then allow the assistant to release the pedal.
5. Repeat until fluid runs clear and free of air bubbles. Move to the next wheel and repeat the process.
6. Ensure all wheels are bled and check fluid level in the reservoir, topping off as needed.

5. Final Checks

Tools Required: None
Sub-steps:
1. Inspect the brake system again for any signs of leaks.
2. Test the brake pedal feel and ensure it is firm.
3. Perform a short test drive to confirm proper brake function.
