Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system.
•Allow brake components to cool before inspection or replacement.

Symptoms

•Steering wheel shakes when brakes are applied
•Vehicle pulls to one side during braking
•Brake pedal pulsates or feels uneven
•Increased stopping distance
•Unusual noise (e.g., grinding or squeaking) when braking

Diagnostic Steps

1
Inspect brake components visually for wear or damage.
2
Check the condition of brake pads and rotors for proper thickness and surface irregularities.
3
Measure rotor runout using a dial indicator to assess warping.
4
Inspect wheel bearings for play or damage.
5
Check tire condition and balance to rule out related shaking issues.
6
Scan for any ABS or traction control error codes using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the wheel bolts.
Lift the vehicle using a jack, secure it with jack stands, and remove the wheel.

3. Inspect and Replace Brake Pads and Rotors

Inspect Brake Pads:
- Remove the caliper by unscrewing the mounting bolts with a socket set.
- Slide the caliper off the rotor and hang it securely (do not let it dangle by the brake line).
- Check the thickness of the brake pads; replace if less than 3mm.
Inspect Rotors:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Check for warping by measuring the rotor thickness and runout.
- If warped or below the minimum thickness, replace the rotor with a new one.
Install New Components:
- Install the new rotor and secure it with retaining screws.
- Replace the brake pads and reposition the caliper, tightening the mounting bolts to manufacturer specifications (typically around 25-35 ft-lbs).

4. Reinstall Wheel

Position the wheel back onto the hub, hand-tighten the lug bolts, and lower the vehicle.
Tighten the lug bolts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

5. Final Checks

Reconnect the battery and perform a test of the braking system by pressing the brake pedal to ensure proper function before driving.
