⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on the brakes.
•Ensure the parking brake is engaged and the vehicle is securely lifted on jack stands before working underneath.

Symptoms

•Brake pedal feels soft or spongy when pressed
•Longer stopping distances than usual
•Brake warning light may be illuminated
•Possible brake fluid leaks observed around brake components
•Unusual noises (squeaking or grinding) when braking
•Reduced responsiveness of brakes

Diagnostic Steps

1
Inspect brake fluid level in the reservoir to ensure it is within the recommended range.
2
Check for any visible leaks in brake lines, hoses, or around calipers and master cylinder.
3
Use an OBD-II scanner to check for any stored error codes related to the brake system.
4
Test the brake booster for proper operation by pumping the brake pedal and checking for loss of vacuum assist.
5
Inspect the brake pads and rotors for wear or damage.
6
Bleed the brake system to remove any air trapped in the brake lines.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to secure the vehicle.

2. Brake Fluid Check

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Inspect fluid level; if low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Tools Required: Brake fluid, funnel (if needed)

3. Inspect for Leaks

Sub-steps:
- Visually inspect brake lines, hoses, and connections for any signs of fluid leaks.
- If leaks are found, replace the affected hoses or seals.
Tools Required: Wrench set, brake line repair kit (if needed)

4. Brake Booster Test

Sub-steps:
- Start the engine and pump the brake pedal several times to deplete vacuum assist.
- Maintain pressure on the pedal and turn off the engine; if the pedal sinks further, the booster may be faulty.
Tools Required: None

5. Brake System Bleeding

Sub-steps:
- Locate the bleeder valves on each brake caliper.
- Attach a clear hose to the bleeder valve and submerge the other end in a container with brake fluid.
- Have an assistant pump the brake pedal several times, then hold it down while you open the bleeder valve to release air and fluid.
- Close the valve before the assistant releases the brake pedal.
- Repeat until there are no air bubbles in the fluid.
Tools Required: Brake bleeder kit, wrenches, clear tubing

6. Brake Pad and Rotor Inspection

Sub-steps:
- Remove the wheel to access the brake caliper.
- Inspect the brake pads for thickness; replace if worn below the manufacturer’s specifications.
- Check the rotors for scoring or warping; replace if necessary.
Tools Required: Socket set, torque wrench, brake pad replacement kit (if needed)
