Important safety information - read before proceeding

•Always wear protective gear when handling brake fluid, as it can damage vehicle paint.
•Ensure the vehicle is securely lifted before working underneath it.

Symptoms

•Brake pedal feels soft or spongy
•Brake warning light illuminated on the dashboard
•Loss of braking power or increased stopping distance
•Fluid leaks under the vehicle near the wheels or under the master cylinder
•Brake fluid reservoir empty or low

Diagnostic Steps

1
Inspect the brake fluid level in the master cylinder reservoir.
2
Check for visible leaks in brake lines, calipers, and the master cylinder.
3
Inspect the condition of brake pads and rotors for wear.
4
Bleed the brake system to remove any air that may have entered.
5
Use a pressure gauge to test the hydraulic pressure at the brake calipers.
6
Scan for any fault codes in the ABS system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear safety goggles and gloves to protect against brake fluid.

2. Inspect and Repair Leaks

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Visually inspect brake lines, calipers, and the master cylinder for leaks.
3. If leaks are found, replace damaged brake lines, calipers, or the master cylinder as needed.
Tools Required: Wrench set, brake line flaring tool (if replacing lines).

3. Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Use a siphon or turkey baster to remove old brake fluid from the reservoir.
3. Refill the reservoir with the correct type of brake fluid (DOT 3 or DOT 4).
Tools Required: Siphon, clean cloth for spills.

4. Bleed the Brake System

Sub-steps:
1. Begin at the furthest brake caliper from the master cylinder (usually the right rear).
2. Attach a clear plastic hose to the bleeder valve and place the other end in a container.
3. Have an assistant pump the brake pedal several times, then hold it down.
4. Open the bleeder valve to release air and fluid, then close it before the pedal is released.
5. Repeat until no air bubbles are visible in the fluid.
6. Move to the next furthest caliper and repeat the process.
Tools Required: Brake bleeder kit, wrench for bleeder valves.

5. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. If the pads are worn below the manufacturer’s specifications, replace them.
2. Remove the caliper using the appropriate socket.
3. Replace the brake pads and reassemble the caliper, ensuring all bolts are torqued to manufacturer specifications.
Tools Required: Socket set, torque wrench.
