Description
Swapping Out Your Disc Brake Rotors on Your Ford Focus ST170 — With TRW
> Disc brake rotors are dead important for stopping your Ford Focus ST170 safely. They're what the brake pads grab onto to slow you down. Over time, rotors can wear out, warp, or even crack, which means your braking won't be as good, especially when you're giving that ST170 some stick.
Spotting the Trouble Signs
• Squealing like a gutted pig or a nasty grinding noise when you hit the brakes
• Feeling a judder or vibration through the brake pedal
• Taking way longer to stop than you reckon you should
• Seeing obvious scoring, cracks, or a build-up of rust on the rotor surface
Will it pass WOF?
Dodgy brake rotors are a quick way to fail your WOF here in NZ. They need to be above the minimum thickness and without any major cracks or damage to pass the test.
DIY or Workshop?
Difficulty: 6/10
Estimated Time: Give yourself 1.5 to 2 hours per axle
Tools You'll Need: Jack and stands (never get under a car supported only by a jack!), wheel wrench, socket set, torque wrench, brake cleaner, and maybe a brake caliper tool.
🛠️ Bob's "Get It Done Right" Companion Checklist
Before you get cracking, grab these must-haves to make the job safer and easier:
• Safety First: Chuck on some Safety Glasses to keep the brake dust and grime out of your eyes.
• Glove Up: A pair of Nitrile Gloves will save your hands from getting covered in brake dust – that stuff's a pain to clean off!
• Brake Dust Buster: Give those new rotors a good spray down with Brake Cleaner before you fit them. Gets rid of any manufacturing gunk.
• No Squeal Zone: A smear of Anti-Seize Caliper Grease on the caliper pins will keep everything moving smoothly and stop those annoying brake squeals.
Expert Recommendation
Worn brake rotors really mess with the safety and performance of your Ford Focus ST170.

Bob at CARFIX is always keen to help you figure out exactly what you need for your Ford Focus ST170. Pop over to Bob's Shop for a yarn!
Fitment Notes
Make sure the rotors you're buying are made for the Ford Focus ST170 from 2002 to 2005. Double-check the rotor diameter and thickness to match what was on there before.

🛠️ 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. GDB1354) to ensure a perfect bed-in and get the job done properly first time!
🧰 What Else You'll Need:
• Safety First: Never work under a vehicle supported only by a jack. Always secure it on heavy-duty safety jack stands.
• 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.
