•Unusual noises when braking (e.g., squeaking or grinding)

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible leaks in the brake lines and around the brake calipers.
3

Solution

1. Preparation

Tools Required: Basic socket set, brake fluid, brake bleeder kit.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Top Off Brake Fluid

Locate the master cylinder reservoir.
Check the brake fluid level; if it is low, top it off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
If the fluid level is low, check for leaks as further bleeding may be necessary.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or a helper, wrench.
Start with the brake furthest from the master cylinder (usually the right rear).
Attach the bleeder hose to the bleeder valve and submerge the other end in a container with brake fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to let air and fluid escape; close the valve before the pedal is released.
Repeat this process until no air bubbles are present in the fluid stream, then move to the next brake (left rear, right front, left front).

4. Inspect and Replace Brake Components (if necessary)

Remove the wheel to access the brake assembly.
Inspect brake pads for excessive wear and replace them if needed.
Check brake rotors for scoring or warping; resurface or replace as required.
Ensure calipers are functioning correctly; replace if they are seized or leaking.

5. Final Assembly and Testing

Reinstall wheels and torque lug nuts to the manufacturer's specifications.
Refill any low brake fluid in the reservoir.
Test the brake pedal for firmness before taking the vehicle for a road test.
