Disc Brake Rotor Replacement Guide — With TRW
> Disc brake rotors – they're those metal discs doing the rounds with your wheels. Pads clamp onto them, slowing you down. Over time, they can wear out, warp, or get grooved. This is especially true for Subarus tackling everything from city streets to back country roads.
Symptoms That Led You Here
• Feeling a wobble or thrum through the brake pedal or steering wheel when you hit the anchors.
• Hearing squeals, scrapes, or graunches when braking.
• Taking what feels like forever to pull up.
• Seeing scoring, ridges, or funny colours on the rotor surface.
• A brake pedal that feels like you're stepping on a sponge.
Will it pass WOF?
Nah, mate. Worn, warped, or cactus brake rotors are a WOF fail. They need to be a minimum thickness and without major cracks to keep you safe.
DIY or Workshop?
Difficulty rating: 6/10
Estimated time: 1-2 hours per axle (front or rear)
Tools required: Jack, jack stands, lug wrench, brake caliper compression tool, socket set, torque wrench, brake cleaner, wire brush, and potentially an impact wrench.

🛠️ Bob's Pro Tip: Do the Job Right!
> If you're swapping out these parts on your vehicle, always install fresh brake pads. Check out our compatible TRW Brake Pads (Part No. GDB3205) to ensure a perfect bed-in and get the job done properly first time!
🧰 What Else You'll Need:

• Brake Dust Protection: Keep a pack of Nitrile Gloves handy to protect your hands from grease and dust.
• Clean and Prep: Use Brake Cleaner to clean the anti-corrosion shipping oil off the new rotors before mounting the calipers.
• Lubrication: Apply caliper grease to caliper slide pins and pad contact points to prevent squealing.
