Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the vehicle to cool down before working on the brakes.

Symptoms

•Grinding noise when applying brakes
•Reduced braking efficiency
•Vibration or pulsation felt in the brake pedal
•Warning light illuminated on the dashboard
•Increased stopping distance compared to normal

Diagnostic Steps

1
Inspect brake pads for wear: Remove the wheel and visually check the thickness of the brake pads.
2
Check brake rotors: Inspect rotors for grooves, scoring, or excessive wear.
3
Listen for noise source: While the vehicle is stationary, have someone apply the brakes to pinpoint the noise location.
4
Inspect brake calipers: Ensure calipers are functioning properly and not sticking.
5
Examine brake fluid: Check fluid level and condition for contamination or air bubbles.
6
Look for foreign debris: Inspect the brake assembly for any rocks or dirt lodged in the system.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads by sliding them out of the caliper bracket.
- Compare new brake pads to old ones for proper fit.
- Apply brake grease to the backing plate of the new pads to prevent noise.
- Install the new brake pads into the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Sub-steps:
- Inspect the rotors for wear and damage; if they are too worn or scored, they should be replaced.
- If resurfacing, use a brake lathe to smooth the rotor surface.
- If replacing, remove the rotor by unscrewing the retaining screws and pulling it off the hub.
- Install the new or resurfaced rotor on the hub.

4. Reassemble Brake Components

Sub-steps:
- Reinstall the caliper over the new pads and rotor.
- Tighten caliper bolts to the manufacturer’s specified torque (typically around 20-30 lb-ft).
- Reinstall the wheel and tighten lug nuts to the recommended torque (usually 80-100 lb-ft).

5. Final Checks

Lower the vehicle and pump the brake pedal to seat the brake pads.
Check brake fluid level and top off if necessary.

Tools Required:

Jack and jack stands
Socket set
Brake grease
Torque wrench
Brake lathe (if resurfacing rotors)

Parts Required:

Brake pads
Brake rotors (if damaged)
Brake fluid (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always disconnect the battery before working on electrical systems.
Allow the vehicle to cool down before working on the brakes.
