•Allow the vehicle to cool before working on the brakes to avoid burns.

Symptoms

•Soft or spongy brake pedal feel
•Extended stopping distance
•Brake warning light illuminated
•Possible fluid leakage around brake components
•Unusual noise when braking

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible brake fluid leaks around brake lines, calipers, and the master cylinder.
3
Use an OBD-II scanner to check for any error codes related to the braking system.
4
Perform a visual inspection of brake pads and rotors for wear and damage.
5
Test the brake booster by pumping the brake pedal with the engine off, then starting the engine to see if the pedal drops slightly.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the cap from the brake fluid reservoir and inspect the fluid condition. If dark or contaminated, proceed to flush the system.
2. Use a brake bleeder kit or a clear tube attached to the bleeder valve to drain old brake fluid.
3. Refill the reservoir with fresh, manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).

Tools Required: Brake bleeder kit, wrench for bleeder valves, funnel.

3. Check and Replace Brake Pads and Rotors

Sub-steps:
1. Loosen the lug nuts and lift the vehicle using a jack, then secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Remove the caliper bolts and carefully slide the caliper off the rotor.
4. Inspect the brake pads for thickness; replace if they are below 3mm.
5. Check the rotors for scoring or warping. Replace if necessary.
6. Install new brake pads and reassemble the caliper.
7. Repeat for the opposite side.

Tools Required: Socket set, torque wrench, caliper tool, brake cleaner.

4. Bleed the Braking System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start at the brake furthest from the master cylinder (usually the right rear).
3. Attach the bleeder tube to the bleeder valve, open the valve, and have an assistant press the brake pedal.
4. Continue to bleed each brake in the following order: right rear, left rear, right front, left front until all air bubbles are removed.
5. Ensure the brake fluid reservoir remains full during this process.

Tools Required: Brake bleeder kit.
