⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on brakes.
•Ensure the vehicle is securely supported on jack stands before working underneath.
•Disconnect the negative battery terminal if working on electronic brakes.

Symptoms

•Brake pedal feels soft or spongy
•Unusual grinding or squeaking noises when brakes are applied
•Vibration or pulsation in the brake pedal
•Brake warning light illuminated on the dashboard
•Reduced stopping power or longer stopping distances
•Brake fluid leaking around the wheels or under the vehicle

Diagnostic Steps

1
Inspect the brake fluid level in the reservoir; ensure it is within the recommended range.
2
Scan the vehicle's onboard diagnostics system using an OBD-II scanner to check for any error codes related to the braking system.
3
Visually inspect brake pads for wear; measure thickness to determine if they need replacement.
4
Check the condition of the brake rotors for warping or scoring; use a micrometer for accurate measurements.
5
Test the brake booster for proper operation; check for vacuum leaks in the booster hose.
6
Inspect brake lines and hoses for leaks or damage; look for signs of corrosion or wear.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety goggles and gloves.

2. Replace Brake Pads

Sub-steps:
1. Jack up the vehicle and remove the wheel using a lug wrench.
2. Remove the caliper bolts with a socket wrench and carefully slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket, ensuring they are properly aligned.
5. Compress the caliper piston using a brake caliper tool to allow the caliper to fit over the new pads.
6. Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

3. Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper and bracket as outlined in the previous section.
2. Remove the retaining screws or bolts securing the rotor to the hub.
3. Slide the old rotor off the wheel hub; clean the hub surface.
4. Install the new rotor ensuring it seats properly; secure with retaining screws or bolts.
5. Reinstall the caliper and brackets.

4. Brake Fluid Replacement

Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. Use a turkey baster to remove old fluid from the reservoir.
3. Fill the reservoir with new brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
4. Bleed the brakes by having an assistant pump the brake pedal while you open and close the bleeder valve on each brake caliper until new fluid flows without bubbles.
