⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the negative battery terminal before working on electrical systems.
•Allow the brake components to cool before handling to avoid burns.

Symptoms

•Hard brake pedal feel during braking
•Reduced braking efficiency
•Increased stopping distance
•Brake warning light illuminated (if applicable)
•Unusual noise from the brake booster (hissing or whistling)

Diagnostic Steps

1
Inspect the brake fluid level and condition in the master cylinder reservoir.
2
Check for vacuum leaks in the brake booster and associated vacuum lines.
3
Test the brake booster operation by applying pressure to the brake pedal before starting the engine; the pedal should lower slightly when the engine is started.
4
Use a multimeter to test the brake light switch for continuity.
5
Inspect the master cylinder for signs of internal failure or leaks.

Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Tools Required: Socket set, wrench set, vacuum gauge, multimeter.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the master cylinder.
2. Check the brake fluid level; if low, refill with the appropriate DOT fluid specified in the owner’s manual.
3. If the fluid appears contaminated or dark, flush the brake system and replace with new fluid.

3. Check and Repair the Brake Booster

Sub-steps:
1. Disconnect the negative battery terminal for safety.
2. Locate the brake booster and inspect for vacuum lines; replace any damaged or cracked lines.
3. Remove the brake booster from its mounting (usually involves removing nuts/bolts with a socket).
4. Test the brake booster by connecting a vacuum gauge; if it does not hold vacuum, replace the brake booster.
5. Reinstall the new or serviced brake booster and reconnect all vacuum lines securely.

4. Test Brake Light Switch

Sub-steps:
1. Locate the brake light switch, typically found near the brake pedal.
2. Disconnect the switch and test with a multimeter for continuity when the pedal is pressed.
3. If the switch does not operate correctly, replace it with a new switch.
