How to Replace Front Brakes 2000-2005 Buick LeSabre

Introduction

This tutorial provides a step-by-step guide on how to replace the front brake pads and rotors on a 2000-2005 Buick LeSabre. Over time, brake pads wear out and may need replacing approximately every 50,000 miles, while brake rotors should be assessed for warping or grooving. Replacing them together can enhance safety and performance.

Step 1: Gather Necessary Tools and Materials

Before starting the brake replacement, gather all required tools and materials to ensure a smooth process:

• Pry Bar
• 15mm Socket
• 19mm Socket
• Brake Caliper Hanger
• Ratchet
• Socket Extensions
• Torque Wrench
• Brake Grease
• Brake Parts Cleaner
• Cloth Rags
• Copper Anti-Seize
• Liquid Thread Locker
• Floor Jack
• Hammer
• Jack Stands
• Wire Brush

Step 2: Prepare the Vehicle

1. Safety First: Park the vehicle on a flat surface and engage the parking brake.
2. Jack Up the Vehicle:
   • Use the floor jack to lift the front of the vehicle.
   • Secure it with jack stands for safety.
3. Remove the Wheel:
   • Use the appropriate socket to remove the lug nuts and take off the wheel.

Step 3: Remove the Brake Caliper

1. Access the Caliper:
   • Locate the caliper mounting bolts (usually 15mm).
   • Use the ratchet and socket to remove these bolts.
2. Hang the Caliper:
   • Use the brake caliper hanger to suspend the caliper securely, ensuring no strain on the brake line.

Step 4: Remove the Old Brake Pads and Rotors

1. Take Out the Pads:
   • Slide the old brake pads out of the caliper bracket.
2. Remove the Rotor:
   • If the rotor is stuck, gently tap it with a hammer.
   • Remove any retaining screws if present.
   • Slide the rotor off the hub.

Step 5: Install the New Rotor

1. Clean the New Rotor:
   • Use brake parts cleaner to remove any protective coating.
2. Attach the New Rotor:
   • Slide the new rotor into place on the wheel hub.
   • Secure it with retaining screws if applicable.

Step 6: Install New Brake Pads

1. Apply Brake Grease:
   • Apply a thin layer of brake grease on the back of the new pads to reduce noise.
2. Insert the New Pads:
   • Slide the new brake pads into the caliper bracket, ensuring they are seated properly.

Step 7: Reinstall the Brake Caliper

1. Compress the Caliper:
   • Use a brake caliper tool or pry bar to compress the caliper piston back into the caliper housing.
2. Reattach the Caliper:
   • Position the caliper over the new pads and rotor.
   • Secure it by tightening the caliper mounting bolts to the specified torque (usually around 20 ft-lbs, check vehicle specifications).

Step 8: Reassemble the Wheel

1. Put the Wheel Back On:
   • Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the Vehicle:
   • Carefully remove the jack stands and lower the vehicle back to the ground.
3. Tighten Lug Nuts:
   • Use the torque wrench to tighten the lug nuts to the manufacturer's specification.
