⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on electrical components.
•Allow the vehicle to cool before working on brakes to avoid burns.

Symptoms

•Brake pedal feels spongy or goes to the floor when pressed
•Increased stopping distance when braking
•Brake warning light illuminated on the dashboard
•Possible fluid leaks under the vehicle
•Unusual noises when the brake pedal is depressed (e.g., grinding or squeaking)

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for visible brake fluid leaks around brake lines, calipers, and wheel cylinders.
3
Examine the brake pads and rotors for excessive wear.
4
Test the brake booster for proper operation by pumping the brake pedal with the engine off, then starting the engine and checking for a change in pedal feel.
5
Use a brake pressure gauge to check for consistent pressure during brake application.

Solution

Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; if low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated (dark or cloudy), proceed to replace it.

3. Inspect and Repair Leaks

Visual inspection of brake lines, hoses, and connections for any signs of leaks.
Tighten any loose connections and replace any damaged lines or hoses as needed.
If leaks are found at the calipers or wheel cylinders, remove and replace the affected components.

4. Brake Pad and Rotor Check

Remove the wheel to access the brake components.
Inspect the brake pads for thickness; replace if less than 3mm.
Measure rotor thickness with a micrometer; resurface or replace if below specifications.
Reassemble the brake assembly and wheel.

5. Bleed the Brake System

Start with the wheel farthest from the master cylinder (usually right rear).
Attach a bleeder hose to the caliper bleeder valve and submerge the other end in a container with brake fluid.
Have an assistant press the brake pedal while you open the bleeder valve to release air; close the valve before the pedal is released.
Repeat for all wheels in the sequence: right rear, left rear, right front, left front.
Ensure the master cylinder remains topped up during this process.
