⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear gloves and goggles when working with brake fluid, as it is corrosive.
•Allow the vehicle to cool before working on the brake system to prevent burns.

Symptoms

•Soft brake pedal feel
•Longer stopping distance
•Brake warning light illuminated on the dashboard
•Unusual noises when braking (squeaking or grinding)
•Fluid leak near the wheels or under the vehicle

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible leaks in brake lines, calipers, or wheel cylinders.
3
Use an OBD-II scanner to check for any related error codes.
4
Inspect brake pads for wear and tear.
5
Test the brake booster for proper operation by pumping the brake pedal with the engine off, then starting the engine to see if the pedal drops slightly.
6
Examine brake lines for any signs of corrosion or damage.

Solution

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Brake Fluid Inspection

Sub-steps:
1. Open the hood and locate the master cylinder reservoir.
2. Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4, depending on specifications).
3. Inspect for signs of contamination (milky appearance).

3. Brake Line and Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect brake lines for leaks or corrosion.
3. Check brake calipers and wheel cylinders for any fluid leaks.
4. If leaks are found, replace the affected component (caliper, cylinder, or line).

4. Brake Pad Replacement (if necessary)

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove the caliper bolts using a socket set and slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly seated.
5. Reinstall the caliper and torque bolts to manufacturer specifications.

5. Brake Booster Test and Replacement (if necessary)

Sub-steps:
1. Disconnect the vacuum line from the brake booster.
2. Use a hand-held vacuum pump to check if the booster holds vacuum.
3. If the booster does not hold vacuum, replace the brake booster.
