⚠️ Safety Warnings

Important safety information - read before proceeding

•Brake fluid is corrosive; avoid contact with painted surfaces and skin.
•Ensure the brake system is depressurized before working on hydraulic components.
•Ensure vehicle is securely supported on jack stands before working underneath.
•Disconnect the battery before working on electrical connectors.

Symptoms

•Brake pedal feels soft or spongy when pressed
•Longer stopping distances
•Brake warning light illuminated on the dashboard
•Fluid leaks visible around brake components
•Unusual noises (e.g., grinding or squeaking) when braking

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for visible leaks in brake lines, calipers, and wheel cylinders.
3
Scan for any error codes related to the braking system using an OBD-II scanner.
4
Test brake pedal feel by applying consistent pressure and observing any changes in pedal travel.
5
Inspect brake pads and rotors for wear or damage.
6
Check the brake booster for proper operation by pumping the brake pedal with the engine off and then starting the engine.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap and check brake fluid level.
2. If fluid is low, top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If fluid is dark or contaminated, perform a complete brake fluid flush.
Tools Required: Brake fluid, funnel
Safety Warnings: Brake fluid is corrosive; avoid contact with painted surfaces and skin.

3. Inspect and Replace Brake Lines or Components

Sub-steps:
1. Visually inspect all brake lines and hoses for signs of leaks or damage.
2. Replace any damaged or corroded brake lines with new lines.
3. If calipers or wheel cylinders are leaking, replace them.
Tools Required: Wrench set, brake line flaring tool (if necessary)
Safety Warnings: Ensure the brake system is depressurized before working on hydraulic components.

4. Brake Pad and Rotor Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; replace if worn below manufacturer specifications.
3. Check rotors for warping or scoring; machine or replace as needed.
Tools Required: Jack and jack stands, socket set, torque wrench
Safety Warnings: Ensure vehicle is securely supported on jack stands before working underneath.

5. Brake Booster Check

Sub-steps:
1. With the engine off, pump the brake pedal several times to deplete any vacuum.
2. Start the engine while pressing the brake pedal; it should feel firmer.
3. If pedal feel does not improve, replace the brake booster.
Tools Required: Basic hand tools for booster replacement
Safety Warnings: Disconnect the battery before working on electrical connectors.
