⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the brakes to cool before inspecting or working on them to avoid burns.

Symptoms

•Brake pedal feels stiff and requires excessive force to depress
•Reduced braking response or delayed braking
•Potentially illuminated brake warning light on the dashboard
•Unusual noises when attempting to brake (e.g., grinding or squeaking)

•Brake fluid leakage underneath the vehicle

Diagnostic Steps

1
Inspect the brake fluid level and condition in the master cylinder reservoir.
2
Check for any visible leaks in the brake lines or around the brake calipers.
3
Test the brake booster by applying the brake pedal and then turning off the engine; the pedal should sink slightly.
4
Use a vacuum gauge to measure the brake booster vacuum; it should be within specifications.
5
Scan the vehicle's onboard diagnostics for any error codes related to the braking system.
6
Visually inspect the brake components, including pads and rotors, for wear or damage.

Solution

1. Preparation

Gather tools: socket set, brake fluid, vacuum gauge, shop towels, and safety glasses.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Restore Brake Fluid

Remove the master cylinder cap and check fluid level; add the proper brake fluid if low.
Inspect the brake fluid for contamination. If dirty, proceed to bleed the brake system.
Clean any spilled brake fluid immediately to prevent damage to vehicle paint.

3. Test and Replace Brake Booster

If the brake booster is faulty, disconnect the vacuum hose and replace the booster.
- Sub-steps:
  - Remove the brake master cylinder by disconnecting brake lines and unbolting it.
  - Unbolt the brake booster from the firewall and carefully remove it.
  - Install the new booster in reverse order, ensuring all connections are secure.
  - Reattach the master cylinder and bleed the brakes to remove air from the system.

4. Check Brake Lines and Components

Inspect brake lines for any signs of wear or leaks; replace any damaged lines.
Inspect brake pads and rotors; replace as necessary with quality aftermarket or OEM parts.
Reassemble all components and ensure all bolts are torqued to manufacturer specifications.
