How to Replace Front Brake Calipers On Any Car!

Introduction

This tutorial will guide you through the process of replacing front brake calipers on any vehicle equipped with modern hydraulic disc brake systems. Whether you're dealing with worn, seized, broken, or leaky calipers, this step-by-step guide is designed to make the replacement straightforward and accessible for DIY enthusiasts.

Step 1: Prepare the Vehicle

• Ensure the vehicle is on a flat surface and secure it with jack stands.
• Use a floor jack to raise the vehicle.
• Remove the wheel by loosening the lug nuts.
  • Tip: Leave one lug nut slightly tightened to prevent the wheel from falling during removal.

Step 2: Access the Brake Caliper

• With the wheel removed, locate the banjo bolt on the caliper.
• Using a socket and ratchet, break free the banjo bolt while the caliper is still attached to the knuckle.
• Remove the bleeder screw cover if present. This protects the bleeder screw from moisture and debris.

Step 3: Remove the Caliper

• Use pliers or a wrench to hold the caliper slider while you remove the slider bolts.
• Keeping one bolt partially threaded will secure the caliper and prevent it from falling.
• Optionally, you can remove the caliper bracket bolts instead, but this tutorial focuses on separating the caliper first.
• Remove the brake pads from the caliper.

Step 4: Detach the Brake Hose

• Use hose pinch-off pliers to prevent fluid from leaking out of the brake line.
• Remove the banjo bolt completely to detach the brake hose from the caliper.
• Ensure that you remove the copper gaskets from the banjo bolt to avoid leaks when installing the new caliper.

Step 5: Compare Old and New Calipers

• Place the new caliper next to the old one to ensure they match in shape, piston type, and bracket height.
• Check that the new caliper includes necessary components such as the banjo bolt and crush washers.

Step 6: Prepare the New Caliper

• Remove any protective packaging from the new caliper.
• Apply a thin layer of brake grease to the caliper sliders and contact points to prevent rust and ensure smooth movement.
• Install the new copper crush washers onto the new banjo bolt before attaching it to the caliper.

Step 7: Install the New Caliper

• Position the new caliper onto the bracket and align it with the mounting holes.
• Start the slider bolts by hand to ensure they are properly threaded before tightening.
• Use a torque wrench to tighten the slider bolts to the manufacturer’s specifications.

Step 8: Reattach the Brake Hose

• Attach the brake hose to the new caliper using the banjo bolt and the copper gaskets.
• Tighten the banjo bolt to the manufacturer’s specifications.

Step 9: Bleed the Brake System

• Pump the brake pedal to extend the caliper piston against the brake pads.
• Open the bleeder screw to release any trapped air until a steady stream of fluid flows out.
• Close the bleeder screw and repeat the process until the brake system is free of air.

Step 10: Final Adjustments

• Clean any excess brake fluid from the caliper area with a rag.
• Replace the bleeder screw cover to protect it from moisture.
• Reinstall the wheel and lug nuts in a star pattern to ensure even tightening.
• Torque the lug nuts to the manufacturer’s specifications.
