Symptoms

•Vibrations felt in the steering wheel during hard braking
•Shaking of the entire car when applying brakes
•Uneven wear on brake pads or rotors
•Possible pulsation in the brake pedal
•Increased stopping distance

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial gauge.
2
Check brake pads for thickness and even wear patterns.
3
Examine suspension components (control arms, bushings, and ball joints) for wear or damage.
4
Verify wheel alignment and balance.
5
Inspect brake calipers for proper operation and ensure they are not sticking.
6
Test drive the vehicle to replicate the shaking issue under controlled conditions.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Front Wheels

Use a lug wrench to loosen wheel nuts.
Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access brakes and suspension components.

3. Inspect and Replace Brake Rotors (if warped)

Sub-steps:
- Remove the caliper bracket by unscrewing the mounting bolts.
- Slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Remove the rotor by unscrewing any retaining screws, if applicable.
- Install new brake rotors, ensuring they are properly seated.
- Reattach the caliper bracket and securely tighten the bolts to manufacturer specifications (typically around 25-35 Nm).

4. Replace Brake Pads (if worn)

Sub-steps:
- Inspect the old brake pads for thickness; replace if they are below the manufacturer's minimum specification (usually around 3 mm).
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads.
- Install new pads and ensure they are properly seated.

5. Reassemble and Reinstall Wheels

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to manufacturer specifications (typically 100-120 Nm).

6. Test Drive and Check

Conduct a test drive to ensure the shaking issue is resolved.
Monitor for any unusual noises or sensations during braking.
