Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brakes to cool before inspection or repair to avoid burns.

Symptoms

•Shaking or vibration felt through the steering wheel when braking
•Pulsating brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise during braking, such as grinding or squeaking

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check the condition of brake rotors for warping by measuring rotor thickness with a micrometer.
3
Examine wheel bearings for play and check for unusual noises.
4
Inspect suspension components (control arms, bushings) for wear and damage.
5
Check tire pressure and inspect tires for uneven wear or damage.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake caliper tool, micrometer, caliper gauge, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check brake pads for thickness; if they are below the manufacturer’s minimum thickness, replace them.
Replacement:
1. Remove the caliper bolts using the appropriate socket.
2. Slide the caliper off the rotor and support it without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket.
5. Compress the caliper piston using a brake caliper tool to accommodate the new pads.
6. Reinstall the caliper and tighten the bolts to manufacturer specifications (typically 25-30 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Measure rotor thickness with a micrometer; if below minimum specs or warped, replace.
Replacement:
1. Remove the caliper assembly as described above.
2. Remove the caliper bracket by unscrewing the bolts.
3. Slide the rotor off the hub; if stuck, tap lightly with a rubber mallet.
4. Install the new rotor and reattach the caliper bracket.
5. Reinstall the caliper over the new pads and secure it.

5. Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to manufacturer specifications (typically 110-120 Nm).
