⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety gear when working on the braking system.
•Ensure the vehicle is securely lifted before working under it.
•Do not allow brake fluid to come into contact with painted surfaces as it can cause damage.

Symptoms

•Soft or spongy brake pedal feel
•Longer stopping distances
•Brake warning light illuminated
•Brake fluid leaking under the vehicle
•Increased pedal travel before engaging brakes

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible leaks in the brake lines or around the brake calipers.
3
Scan the vehicle using an OBD-II scanner for any brake system error codes.
4
Inspect brake pads and rotors for wear or damage.
5
Test the brake booster for proper operation by pumping the brake pedal with the engine off and then starting the engine to see if the pedal drops slightly.
6
Check the brake system for air bubbles by bleeding the brakes if necessary.

Solution

Solution

1. Preparation

Gather tools and parts needed for the repair.
Safety gear such as gloves and goggles should be worn.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Remove the master cylinder cap and inspect brake fluid for contamination (color should be clear).
- If fluid is dirty, use a turkey baster to remove old fluid and replace with new DOT 3 or DOT 4 brake fluid.
- Reinstall the master cylinder cap securely.

3. Check for Leaks and Replace Components

Sub-steps:
- Visually inspect all brake lines, calipers, and wheel cylinders for leaks.
- Replace any damaged or corroded brake lines using a line wrench to avoid stripping.
- If calipers are leaking, replace them with new calipers, ensuring proper torque specifications when installing (usually around 20-30 ft-lbs).

4. Bleed the Brake System

Sub-steps:
- Start at the wheel farthest from the master cylinder (usually the right rear), and use a brake bleeder kit or a helper to pump the brake pedal.
- Open the bleeder screw on the caliper, allowing old fluid and air to escape until clear fluid flows out.
- Close the bleeder screw and repeat for the left rear, right front, and finally the left front.
- Ensure the master cylinder does not run dry during the process.

5. Final Inspection

Sub-steps:
- Recheck the brake fluid level and top off if necessary.
- Test the brake pedal feel before road testing.
- Ensure all tools are removed from the engine bay and wheel wells.
