How to Change Brake Pads on a Subaru Outback | Comprehensive Guide

Introduction to Subaru Outback Brake Servicing

If you own a Subaru Outback, especially models from the early 2000s, you may have experienced the frustration of needing regular brake pad replacement. This guide is designed to help you understand the process and ensure that you perform the task correctly. Understanding and maintaining your brakes is crucial for your safety and the overall performance of your vehicle.

Understanding the Importance of Brake Pad Replacement

The brake pads on a Subaru Outback, similar to those on your 2007 Impreza, are a critical component that ensures the vehicle stops safely. Over time, these pads wear down due to friction and repeated use. If not replaced in a timely manner, they can cease to function properly, leading to dangerous situations. While it might seem like a straightforward task, proper care and technique are essential.

Signs That You Need New Brake Pads

There are several indicators that your brake pads on a Subaru Outback may need attention:

Noisy brakes: When you apply the brakes, you might hear squealing, grinding, or other unusual noises. These sounds can indicate that the pads are worn out or that the rotor surface is uneven.

Decreased stopping power: If your car takes longer to stop or feels less responsive, it could be a sign that brake components are failing.

Vibrating brake pedal: A pulsing or vibrating pedal can indicate that the rotors need to be resurfaced or that the pads and rotors are misaligned.

Tools and Materials Needed

To change the brake pads on your Subaru Outback, you'll need the following tools and materials:

Lift or jack stands: To safely raise the vehicle off the ground.

Brake lube: To lubricate the brake calipers and sliders, which prevents them from seizing up.

New brake pads: Choose quality pads that are appropriate for your vehicle's make and model. Consult with a professional or the vehicle's owner manual for recommendations.

C-clamp: To retract the caliper piston if necessary.

Allen keys and wrenches: For removing bolts and nuts.

Bullet grinder (if needed): To smooth out any grooves or damage on the rotors.

Step-by-Step Guide to Changing Brake Pads on a Subaru Outback

Step 1: Prepare the Vehicle

Start by setting up your vehicle on a level surface. Use a jack or a lift to raise the vehicle until it's stable on jack stands. Turn the wheels to the locked position to secure the vehicle.

Step 2: Remove the Old Brake Pads

Access the brake calipers and use an Allen key or wrench to remove the bolt holding the caliper onto the hub. Back the old brake pads out of the caliper carriage while making sure not to damage the adaptive slacker wires. If the pistons are stuck, use a c-clamp to retract them.

Step 3: Clean and Inspect the Rotor

Examine the brake rotor for damage, grooves, or excessive wear. Use a bullet grinder to remove any high spots or damage if necessary. Clean the rotor with brake cleaner and inspect for cracks.

Step 4: Install the New Brake Pads

Insert the new brake pads into the caliper carriage, ensuring they are securely in place. Align them properly with the guide pins and slidet tabs. Apply a thin layer of brake lubricant to the guide pins and slidet tabs to prevent seizing.

Step 5: Secure the Caliper

Secure the caliper back to the hub using the bolt you removed earlier. Ensure it is tight and snug, but not overly tight to avoid damage to the caliper or hub.

Step 6: Reset the Brake Warning Light

Once both sides are done, reset the ABS system and the brake warning light. You can do this by driving the car and applying the brakes a few times, or by using a code scanner to clear the codes.

Additional Tips for Maintaining Your Brakes

Maintaining your brakes is a high priority. Here are some additional tips to keep in mind:

Regular Service: Check your brake pads regularly, ideally every 10,000 to 15,000 miles. It's better to replace them periodically to avoid the risk of seizing.

Professional Inspection: If you're unsure about the brake system's health, consult a trusted mechanic. Regular professional inspections can catch issues before they become major problems.

Common Mistakes: Avoid making common mistakes such as improperly installing new pads, not lubricating the sliders, or ignoring warning signs. Properly servicing your brakes is key to your safety and your vehicle's longevity.

Conclusion

Changing the brake pads on a Subaru Outback can be a technical and iterative process, but it is entirely manageable with the right steps and materials. Remember that safety is paramount, and if you're not confident in your abilities, don't hesitate to seek professional help. Regular maintenance can save you from serious issues down the road and ensure your vehicle's performance remains at its best.
