Removing the Wheel

To begin the brake replacement, you will need to elevate the rear of your Mini Cooper and remove its rear wheels. Here are the detailed steps to do that:

1. **Safety First:** Before jacking up your car, engage the parking brake to ensure it remains securely in place.

2. **Position the Jack:** Locate the designated jack points at the rear of your Mini Cooper and carefully position the jack beneath one of these points. Consult your owner’s manual for specific jack point locations.

3. **Raise and Secure:** Using the jack, gradually lift the rear of your car until there is approximately 6 inches of clearance between the ground and the tire you intend to remove. Securely place a jack stand next to the jack to provide additional stability and support.

4. **Remove Lug Nuts:** Retrieve the lug wrench and carefully loosen the lug nuts on the selected wheel, but do not remove them entirely.

5. **Detach the Wheel:** Once the lug nuts have been loosened, gently lift the wheel straight towards you to detach it from the wheelbase. Be cautious as the wheel may be slightly heavy.

**Repeat for Other Side:** Perform steps 1-5 to remove the wheel on the opposite rear side of your Mini Cooper.

Disconnecting the Brake Caliper

Now that you’ve removed the caliper mounting bolts, it’s time to carefully disconnect the brake caliper from the rotor. Use a flathead screwdriver to gently pry the caliper away from the rotor. Be careful not to damage the brake pads or the caliper itself. You may have to use a bit of force, but don’t rush it.

Once the caliper is loose, you’ll need to lift it up and away from the rotor. Be careful not to pull on the brake hose as you do this. You may have to maneuver the caliper a bit to get it free. Once it’s clear, you can set it aside on a clean surface.

Now that the caliper is disconnected, you can remove the old brake pads. They should simply slide out of their slots in the caliper. If they’re stuck, you can use a flathead screwdriver to gently pry them out. Once the old pads are removed, you can clean the caliper and rotor with brake cleaner. This will remove any dirt or debris that may have accumulated on the surfaces.

Tip:
When disconnecting the brake caliper, be careful not to damage the brake hose. This hose is responsible for carrying brake fluid to the caliper, and if it is damaged, it can lead to brake failure.

Removing the Old Brake Pads

Locate the brake caliper. It’s the metal block that houses the brake pads and pistons, usually located on the back of the wheel assembly.
Use an impact wrench or socket wrench to loosen the caliper bolts. There are typically two bolts on each caliper.
Gently pry the caliper off the brake rotor. Use a pry bar as needed, but avoid damaging the caliper or rotor.
Inspect the caliper and pads for wear or damage. Replace any worn or damaged components as necessary.
Remove the old brake pads. They may be held in place by retaining clips. Use a flathead screwdriver or brake pad removal tool to push the clips out of the way.

**Detailed Instructions for Removing the Brake Pads:**

If the old brake pads have a wear indicator, you may hear a squealing or screeching noise when you brake. This noise indicates that the pads are worn down and need to be replaced.
Use a brake cleaner to clean the surface of the caliper and brake rotor. This will remove any dirt or debris that could interfere with the installation of the new brake pads.
Apply a small amount of brake grease to the back of the new brake pads. This will help to reduce noise and improve performance.
Carefully insert the new brake pads into the caliper. Ensure the pads are properly aligned with the brake rotor.
Secure the new brake pads by snapping the retaining clips back into place.
Double-check that all components are properly installed and tightened.

Inspecting and Cleaning the Caliper and Rotor

Replacing the Brake Pads

1. Use a 13mm socket wrench to remove the caliper mounting bolts.
2. Carefully lift the caliper off the rotor and support it with a bungee cord or wire. Do not allow the caliper to hang by the brake line.
3. Remove the old brake pads and inspect the caliper piston and slide pins for any damage or wear.
4. Clean the caliper piston with a brake cleaner and a soft cloth.
5. Apply a thin layer of brake grease to the contact points on the slide pins.
6. Install the new brake pads into the caliper. Ensure that the pads are seated properly in the slots and that the wear indicator tabs are facing outward.
7. Carefully slide the caliper back over the rotor and secure it with the mounting bolts.

Inspecting and Cleaning the Rotor

1. Inspect the rotor for any cracks, scoring, or warping.
2. If the rotor is visibly damaged, it should be replaced.
3. Using a brake cleaner and a soft cloth, clean the surface of the rotor to remove any dirt or debris.
4. If the rotor is heavily rusted, it may be necessary to use a wire brush to remove the rust.
5. Once the rotor is clean, apply a thin layer of anti-seize lubricant to the hub surface.

Installing New Brake Pads

1. Remove the caliper mounting bolts and lift the caliper off the rotor. Do not allow the caliper to hang by the brake hose.

2. Remove the old brake pads from the caliper bracket.

3. Clean the caliper bracket and piston with brake cleaner.

4. Apply a thin layer of brake pad grease to the back of the new brake pads and the caliper bracket where the pads will contact.

5. Install the new brake pads into the caliper bracket.

6. Reinstall the caliper over the rotor and torque the caliper mounting bolts to the specified torque.

7. Pump the brake pedal several times to seat the new brake pads. 1. Remove the old brake pads:

Using a flathead screwdriver or a brake pad spreader tool, carefully pry the old brake pads off of the backing plate. Be careful not to damage the backing plate or the caliper.

2. Clean the caliper and backing plate:

Using a brake cleaner and a clean rag, remove any dirt or debris from the caliper and the backing plate. This will help ensure that the new brake pads make good contact with the caliper and the rotor.

3. Install the new brake pads:

Apply a thin layer of brake grease to the back of the new brake pads and to the caliper where the pads will contact. This will help prevent squealing and ensure that the pads move smoothly in the caliper.

Reattaching the Brake Caliper

Once the rotor is replaced, it’s time to reattach the brake caliper. To do this:

Lift the caliper back into place: Carefully lift the brake caliper back into its original position, making sure the guide pins slide easily into the bracket.
Tighten the caliper bolts: Hand-tighten the two caliper bolts onto the bracket, then use a torque wrench to fully tighten them to the specified torque.
Attach the brake pad retaining clips: Locate the brake pad retaining clips, which were removed earlier. Insert them into the brake pads and ensure they fit snugly.
Reinstall the brake pads: Slide the new or resurfaced brake pads back into the caliper bracket, ensuring they fit properly.
Tighten the caliper mounting bolts: Use a torque wrench to fully tighten the caliper mounting bolts to the specified torque.
Connect the brake line: Locate the brake line that connects to the caliper and reconnect it. Tighten the banjo bolt or bleed screw firmly.
Bleed the brakes: Use a brake bleeding kit to flush out any air from the brake lines. Pump the brake pedal slowly to remove any pressure and then open the bleeder screw on the caliper. Close the bleeder screw once clean brake fluid appears without any air bubbles.
Repeat for the other side: Repeat the entire process for the opposite rear wheel to replace the other pair of brake pads and rotor.

Once both rear wheels are complete, test the brakes gently and confirm their proper operation. Tighten any loose bolts or fittings as necessary before driving the vehicle normally.
