xNo Adapters Needed: Direct-Fit 6-Piston Brakes for GWM Cannon / Poer / P-Series
Adapter brackets are one more thing to flex or loosen when you work your truck hard. We removed them. This Cannon / Poer / P-Series-specific 6-piston big brake kit uses a caliper with forged, integrated mounting ears that bolt directly to the factory knuckle. You keep the stock hub and dust shield, but gain a more rigid connection, firmer pedal feel, and a clean, bolt-on install.
Paired with oversized high-carbon rotors, the system is sized for real pickup use: a tray full of tools, a canopy and rooftop tent, plus a braked trailer in the 3,000–3,500 kg (approx. 6,600–7,700 lb) range, depending on market and trim. It gives you repeatable braking performance on long downhill runs, highway merges, and sudden stops in traffic, while clearing factory 17" and larger wheels.
Technical Specifications & Kit Options for GWM Cannon / Poer / P-Series
The specs below show how this kit is matched to the Cannon / Poer / P-Series platform's towing and payload capability. The integrated mounting ears eliminate the separate adapter bracket, and the 335 mm rotor increases heat capacity for repeated stops when the bed is loaded or a trailer is attached. The kit is supplied only with our high-carbon rotors and includes M-01 street performance pads as standard.

Will It Fit? Your 3-Step Check
1. Wheel Diameter
Confirm you are running 17" or larger wheels.
2. Spoke Clearance
Measure from the rotor mounting face to the back of the wheel spokes. You need at least 99 mm (3.90 in) of clearance.
3. Vehicle Model
Please use the compatibility list or contact us with your GWM Cannon / Poer / P-Series year, body style, and drivetrain to confirm.
Want a printable fitment template? Contact us with your vehicle's year, make, and model, and we'll email you a 1:1 wheel-clearance template.
Frequently Asked Questions
What's the main advantage of the integrated mounting?
Strength and simplicity. By forging the mounting points directly into the caliper body, we eliminate the separate adapter bracket—a potential point of flex or failure in other kits. On a working truck like the Cannon / Poer / P-Series, that extra rigidity translates to a firmer pedal feel and more consistent braking when the vehicle is loaded or towing.
Will this clear my truck's stock wheels?
In most markets, the Cannon / Poer / P-Series is delivered with 17" or 18" wheels. This kit is designed to clear the OEM wheel package and many popular aftermarket off-road wheels, as long as they are 17" or larger and provide at least 99 mm (3.90 in) of spoke clearance. If you are running non-stock wheels, we recommend checking with our printable template or sending us a photo and your wheel specs.
Why use a one-piece rotor on a work truck?
Strength for towing and payload. For a mid-size pickup that regularly carries tools, gear, or up to around 1,000 kg (2,200 lb) in the bed and tows 3,000–3,500 kg (6,600–7,700 lb), a single-piece high-carbon steel rotor offers a strong, low-maintenance solution. There are fewer hardware interfaces to loosen, making it well suited to dirt roads, construction sites, and long-distance touring.
What's in the box? Is this a complete kit?
Yes, this is a comprehensive, vehicle-specific system engineered for a complete bolt-on installation on the Cannon / Poer / P-Series platform. Each kit includes:
- 2x 6-Piston Forged Calipers with Integrated Mounting (Cannon / Poer / P-Series-specific)
- 2x 1-Piece 335 mm High-Carbon Steel Rotors
- 1x Set of M-01 Street Performance Brake Pads
- 2x Stainless Steel Braided Brake Hoses (Cannon / Poer / P-Series-specific)

xHeads Up! What to Know Before You Install
You’re here because you’re passionate about your ride, and so are we. We want your TTSPORT brake upgrade to be a total win. Here’s some straight talk to make sure everything goes smoothly, from fitment to bedding in.
Our Return Policy
Look, we know you get it. Your brake kit is custom-made for your specific car. That means once it's built, it's yours. We can only accept returns if there’s a genuine quality defect from our side.
Sometimes, aftermarket wheels can be tricky. Depending on the design, you might need spacers for clearance. We’ll do our best to help you figure it out, but issues related to wheel spacers don't qualify for a return.
1. Let's Nail the Fitment
To get this right the first time, we need your help. Before you order, please give us the following info:
- Your vehicle's Make, Model, Year, and VIN.
- Your wheel size and specs.
We’ll likely ask you to confirm some measurements and send a few photos of your wheels. Please double-check everything you send us. TTSPORT isn't responsible for fitment issues if the specs you provided were off.
We check every single part before it leaves our shop. When your kit arrives, give it a good look-over. If you spot any potential quality issues, let us know within 24 hours.
2. The Fun Part: Bedding In Your New Brakes
This is key to awesome performance. Don't skip it.
- Find a safe, open road. Bring your car up to 40 mph (approx. 65 km/h) and apply firm, steady pressure to slow down to 10 mph (approx. 15 km/h). Don't come to a complete stop. Do this 10 times to get the pads and rotors acquainted.
- For the next 300-600 miles (approx. 500-1,000 km), take it easy. No crazy hard stops. This cures the pads and rotors and ensures a long, happy life.
- You'll notice our high-carbon steel rotors have a colored, grooved surface. This isn't just for looks—it helps speed up the bedding-in process and fights off corrosion.
3. Our Promise: The TTSPORT Warranty
We build our kits to last, and we stand by our work. Here’s the breakdown:
- Calipers: Covered for 1 year against manufacturing defects. We also offer lifetime maintenance (you just pay for parts).
- Rotors & Hoses: Covered for 90 days against manufacturing defects. These are wear items, but you can expect them to last 25,000-35,000 miles (approx. 40,000-60,000 km) depending on your driving style.
- Brake Pads: Covered for 90 days against manufacturing defects. Typically good for 15,000-25,000 miles (approx. 25,000-40,000 km).
- Custom Hats/Brackets: We guarantee they'll fit perfectly out of the box. Once they're installed, they're not covered under warranty.
4. Pro Tips for Long-Lasting Performance
- After a session of hard driving, let your brakes cool down naturally. Don't spray them with cold water—that's a fast way to warp rotors.
- Brakes feel different in the rain. Give yourself some extra stopping distance.
- If you hear or feel anything weird—grinding, shaking, etc.—talk to your installer right away.
Recommended Service Intervals:
- Rotors: Replace them when wear exceeds 3 mm (approx. 0.12 inches).
- Front Pads: Plan on swapping them every 20,000 miles (approx. 32,000 km) or so.
- Rear Pads: Usually last longer, around 35,000 miles (approx. 56,000 km).
- Brake Fluid: Flush and replace every 25,000 miles (approx. 40,000 km) or every 2 years, whichever comes first.
