Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool before working on the braking system.

Symptoms

•Brake pedal feels excessively stiff or hard to press
•Vehicle does not decelerate smoothly
•Increased stopping distance
•Unusual noises during braking (squeaking or grinding)
•Warning lights on the dashboard related to the braking system

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any braking system-related fault codes.
2
Inspect brake fluid level in the master cylinder reservoir to ensure it is within the recommended range.
3
Visually inspect brake pads for wear and tear; check for uneven wear or damage.
4
Examine brake rotors for warping or scoring that may affect braking performance.
5
Check brake lines for any leaks, cracks, or damage that could compromise brake fluid pressure.
6
Test brake booster operation by applying pressure to the brake pedal with the engine off, then starting the engine to see if the pedal sinks.

Solution

Solution

1. Preparation

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

2. Brake Fluid Inspection and Replacement

Check Brake Fluid Level: Remove the cap from the master cylinder and visually inspect the fluid level.
Top Off Fluid: If low, use the manufacturer's recommended brake fluid (DOT 3 or 4) to fill it to the appropriate level.
Check for Contamination: If the fluid is dark or contaminated, proceed to replace it.

3. Brake Pad Replacement

Remove Wheel: Use a socket set to loosen the lug nuts, then jack up the vehicle and remove the wheel.
Remove Caliper: Use the appropriate socket to remove the caliper bolts. Support the caliper with a bungee cord or rope to prevent strain on the brake line.
Replace Brake Pads: Remove old brake pads and install new ones, ensuring they are oriented correctly. Apply brake grease to the backing of the pads to prevent squeaking.
Reattach Caliper: Position the caliper back over the new pads and torque the caliper bolts to the manufacturer's specifications.

4. Brake Rotor Replacement (if necessary)

Remove Rotor: If the rotor is warped or damaged, remove it by unscrewing the retaining screws and sliding it off the hub.
Install New Rotor: Place the new rotor onto the hub, ensuring it is seated properly. Reattach any retaining screws.
Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts before lowering the vehicle.

5. Final Checks and Brake Bleeding

Bleed Brakes: If brake fluid was replaced, bleed the brake lines to remove any air bubbles. Start from the farthest wheel from the master cylinder and work your way closer, using the two-person pump and hold method or a brake bleeder tool.
Check for Leaks: Inspect all connections and fittings to ensure there are no leaks.
