Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel.
Locate the brake master cylinder reservoir.
If the fluid level is low, clean the reservoir cap before removing it.
Use a funnel to add brake fluid to the recommended level, ensuring it meets the manufacturer’s specifications (DOT 3 or DOT 4 as specified).

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake cleaner, rags.
Visually inspect all brake lines and connections for signs of leaks.
Tighten any loose fittings or replace damaged brake lines.
If leaks are found in the calipers, replace the calipers as necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, catch container.
Begin at the furthest wheel from the master cylinder (typically the passenger side rear).
Attach the clear tubing to the bleeder valve and place the other end in the catch container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow fluid and air to escape; close the valve before the assistant releases the pedal.
Repeat until fluid runs clear, and then proceed to the next wheel.
Ensure to keep the master cylinder topped up during this process.
