⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system.
•Ensure the vehicle is securely supported before working underneath.

Symptoms

•Steering wheel shakes during braking
•Vibration felt in the brake pedal
•Uneven brake wear observed
•Increased stopping distance
•Possible noise when braking (squeaking or grinding)

Diagnostic Steps

1
Inspect brake pads and rotors for wear and warping using a visual inspection.
2
Check wheel alignment and balance; look for any bent rims or misaligned suspension components.
3
Scan for any error codes that could indicate issues with the brake system (e.g., ABS faults).
4
Measure rotor thickness using a micrometer to ensure they are within specification.
5
Inspect brake calipers for sticking or malfunctioning components.
6
Check tire condition and pressure to rule out uneven tire wear.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, micrometer, torque wrench, brake cleaner, safety glasses, and gloves.
Raise the vehicle using a jack and secure with jack stands.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Pads and Rotors

Inspect Brake Pads:
- Remove the wheel using a lug wrench.
- Inspect brake pads for thickness; replace if less than 3mm.
Remove Brake Caliper:
- Use the socket set to remove caliper mounting bolts.
- Hang the caliper using a bungee cord to avoid stressing the brake line.
Remove Brake Rotor:
- Remove any retaining screws if present.
- Slide off the rotor; inspect for warping or scoring.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub.
Install New Brake Pads:
- Apply brake grease to the back of the new pads (avoid the friction surface).
- Reattach the brake caliper over the new pads and torque the bolts to manufacturer specifications (usually around 25-35 ft-lbs).

3. Check Wheel Alignment and Balance

After replacing brake components, check the alignment of the front wheels.
Adjust if necessary and ensure that the tires are balanced.

4. Reinstall Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-130 ft-lbs).
