why does my Toyota Camry XV50 have a pulsating brake pedal

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

• Use a lug wrench to loosen and remove the lug nuts.
• Lift the vehicle using a jack and secure it on jack stands.
• Remove the wheel to access the braking system.

3. Inspect and Replace Brake Rotors

• Inspection: Use a dial indicator to measure rotor runout; if warping exceeds manufacturer specifications, replace the rotors.
• Removal: Remove the caliper by unbolting it from the bracket and hang it using a wire to prevent strain on the brake line.
• Replace: Remove the old rotor by unscrewing any retaining screws or bolts, and slide the new rotor onto the hub. Ensure it is seated properly.

4. Replace Brake Pads

• Remove the old brake pads from the caliper bracket.
• Compress the caliper piston using a caliper tool to create space for the new pads.
• Install new brake pads according to manufacturer specifications, ensuring proper orientation.

5. Reassemble and Test

• Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts to the specified value.
• Reconnect the negative battery terminal.
