Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems if electrical components are involved.
•Allow brake components to cool before handling to avoid burns.

Symptoms

•Grinding noise during braking
•Vibration felt through the brake pedal
•Reduced braking efficiency
•Possible warning light on the dashboard (ABS or brake warning light)
•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads for wear and damage using a visual inspection.
2
Check brake rotors for scoring or warping.
3
Examine caliper operation and ensure they are not sticking.
4
Inspect brake fluid level and condition.
5
Listen for noise while applying brakes in a stationary position to differentiate between brake and suspension noise.

Solution

Diagnostic Steps

1
Inspect brake pads for wear and damage using a visual inspection.
2
Check brake rotors for scoring or warping.
3
Examine caliper operation and ensure they are not sticking.
4
Inspect brake fluid level and condition.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check brake pads for wear; if the thickness is less than 3 mm, they should be replaced.
Removal:
1. Remove the caliper bolts using a socket wrench.
2. Slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
3. Remove old brake pads from the caliper bracket.
Installation:
1. Apply brake grease to the back of the new brake pads.
2. Install new brake pads into the caliper bracket.
3. Reattach the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 20-30 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are worn or scored, they should be replaced.
Removal:
1. Remove the caliper bracket if necessary for rotor access.
2. Remove the rotor from the hub, which may require tapping it gently to dislodge.
Installation:
1. Clean the new rotor with brake cleaner to remove any protective coating.
2. Install the new rotor onto the hub.
3. Reinstall the caliper bracket and torque bolts to specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (typically around 80-100 lb-ft).
Pump the brake pedal a few times to seat the brake pads.
Test drive the vehicle to ensure the grinding noise is resolved.
