how to change drum brakes to disc brakes in car

Converting Drum Brakes to Disc Brakes in Your Car

Upgrading your car's braking system from drum brakes to disc brakes can drastically enhance its performance and safety. Disc brakes offer better stopping power, improved heat dissipation, and reduced brake fade, making them a popular choice among car enthusiasts and performance drivers alike. Below, we will outline key steps and considerations for this conversion.

Understanding the Basics

First, it's essential to understand the differences between drum brakes and disc brakes. Drum brakes consist of a cylindrical drum that rotates with the wheel, with brake shoes that press against the inside of the drum. Conversely, disc brakes utilize a rotor that spins with the wheel and calipers that squeeze brake pads against the rotor to create friction. This results in more effective braking, especially under heavy loads or high temperatures.

Gathering Necessary Parts

Before you begin, you'll need to gather the essential parts for the conversion. Typical components required include

1. Disc Rotors - Ensure they are compatible with your vehicle's specifications. 2. Calipers - Choose calipers that fit your rotors and are suitable for your car model. 3. Brake Pads - Select high-quality pads designed for disc braking systems. 4. Brake Lines and Hoses - You may need new lines to accommodate the new system. 5. Mounting Brackets and Hardware - These adapt your existing suspension setup to fit the new components.

It’s advisable to source parts that are made specifically for your vehicle to ensure compatibility and avoid issues during installation.

Tools Required

The following tools will aid in the disassembly and reassembly required for the conversion

Step-by-Step Conversion Process

1. Safety First Begin by ensuring the car is on a flat surface; use wheel chocks on the opposite wheels and engage the parking brake. Lift the car using a jack and secure it with jack stands.

2. Remove Existing Drum Brakes Start by removing the wheel. Then take off the drum by unscrewing the hardware holding it in place. Remove the brake shoes and associated hardware.

3. Install New Hardware - Fix the mounting brackets for the calipers onto the rear axle or the knuckle. This will allow the calipers to attach securely. - Attach the new brake rotors to the wheel hub, ensuring they fit snugly and are free of debris.

4. Mount the Calipers Position the calipers over the rotors and attach them according to the manufacturer's specifications. Make sure they align properly so that the brake pads will contact the rotor uniformly.

5. Attach Brake Lines Connect the brake lines to the calipers, ensuring all fittings are tight to prevent leaks. If you’ve replaced your brake lines with new ones, bleed the brake lines to remove any air.

6. Install Brake Pads Insert the new brake pads into the calipers. Ensure they fit securely against the rotors.

7. Testing Before driving, double-check all connections and fittings. Reinstall the wheel and lower the car to the ground. Press the brake pedal a few times to seat the pads against the rotors, then perform a test drive at low speeds to ensure everything works properly.

Conclusion

Converting drum brakes to disc brakes can significantly improve your vehicle's braking capabilities. However, if you are inexperienced with car repairs, consider seeking professional help to guarantee safety and effectiveness. With proper attention and care, this upgrade can enhance your driving experience and bring peace of mind on the road.
