•Increased stopping distance

Diagnostic Steps

1
Inspect the brake rotors for warping or damage using a runout gauge.
2
Check brake pad condition for uneven wear or contamination.
3
Examine suspension components (control arms, bushings, tie rods) for wear or damage.
4
Verify wheel alignment and balance.
5
Test brake calipers for proper operation and ensure they are not sticking.
6
Scan for any relevant error codes using an OBD-II scanner.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to eliminate electrical hazards.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the wheel is still on the ground.
Jack the vehicle up and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect: Use a runout gauge to measure rotor runout. If it exceeds specifications (typically 0.002 inches), it is warped.
Replace: If warped, remove the caliper by unscrewing the caliper bolts (typically 13mm or 15mm).
- Tools Required: Socket set, torque wrench.
- Safety Warnings: Ensure the brake fluid reservoir cap is removed to relieve pressure.
Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, securing it with retaining screws if applicable.
Torque Specifications: Ensure rotor retaining screws are tightened to manufacturer specifications (usually around 7-10 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect: Check brake pads for uneven wear or glazing.
Replace: If required, remove the caliper bracket using the appropriate socket size.
- Remove old pads and install new pads, ensuring they are seated correctly.
- Reattach the caliper bracket and caliper, torqueing the bolts to manufacturer specifications (typically 20-25 ft-lbs).

5. Reinstall Wheel and Lower Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually 80-100 ft-lbs in a star pattern).

6. Test Drive

After repairs, perform a test drive to ensure the issue is resolved and brakes function properly.
