The CFMOTO 450 MT is a capable adventure-oriented motorcycle that handles a wide range of terrain, from smooth tarmac to loose gravel tracks. Like any bike that works hard across varied conditions, its braking system needs regular attention to stay safe and effective. Replacing the rear brake pads is one of the most straightforward maintenance tasks you can do yourself, and knowing how to do it correctly makes a real difference to both safety and brake feel. This guide walks you through everything you need to know, from identifying the right pads to bedding them in properly after installation.
What are the rear brake pads on the CFMOTO 450 MT?
The rear brake pads on the CFMOTO 450 MT are friction components housed inside the rear brake caliper. They press against the brake disc when you apply the rear brake, converting kinetic energy into heat and slowing the wheel. The 450 MT uses a hydraulic disc brake system at the rear, so the pads are squeezed by pistons actuated by brake fluid pressure rather than a mechanical cable.
The pads themselves consist of a metal backing plate bonded to a friction material compound. That compound determines how the brakes feel and perform. Most stock pads on mid-range adventure bikes use a semi-metallic compound, which offers a reasonable balance between bite, modulation, and durability. Aftermarket options include sintered pads, which are harder-wearing and perform better when wet, and organic pads, which tend to offer a softer, more progressive feel but wear faster under heavy use.
Understanding what type of pad is already fitted helps you choose a compatible replacement. The CFMOTO 450 MT uses a standard caliper design that accepts a defined pad shape, so always verify the part number or cross-reference the pad dimensions before purchasing.
When should you replace the rear brake pads on a CFMOTO 450 MT?
You should replace the rear brake pads on the CFMOTO 450 MT when the friction material wears down to approximately 1.5 to 2 mm in thickness, or when you notice a clear change in braking performance. Most manufacturers recommend inspection every 5,000 to 10,000 km, but riding style and terrain have a significant impact on the wear rate.
Several signs point to pads that need replacing sooner rather than later:
- Reduced braking power even when applying firm pressure to the rear brake lever or pedal
- A grinding or scraping noise when braking, which indicates the friction material has worn through and metal is contacting the disc
- A spongy or soft feel at the brake pedal, though this can also indicate a fluid issue
- Visible wear when you look through the caliper inspection window or remove the wheel for a closer look
- Brake dust accumulation on the wheel that looks heavier or different in colour than usual
Adventure and dual-sport riding puts more demand on rear brakes than typical road use. If you regularly ride off-road or carry heavy luggage, check your pads more frequently. Catching worn pads early protects the brake disc from damage, which is a far more expensive repair.
What tools and parts do you need to replace the rear brake pads?
To replace the rear brake pads on the CFMOTO 450 MT, you need a basic set of hand tools, a replacement set of pads, and a few consumables. Having everything ready before you start makes the job straightforward and avoids unnecessary interruptions.
Tools
- Socket set and ratchet (typically 8 mm, 10 mm, and 12 mm)
- Allen key set (hex keys), including 5 mm and 6 mm sizes
- Flat-bladed screwdriver or brake piston tool for pushing back the caliper piston
- Torque wrench (for reinstalling caliper bolts to the correct specification)
- Clean rags or workshop paper
- Brake cleaner spray
- Nitrile gloves
Parts and consumables
- Replacement rear brake pads compatible with the CFMOTO 450 MT caliper
- Copper grease or anti-squeal compound (for the pad backing plates only, never on the friction surface)
- Fresh brake fluid (DOT 4, as specified for the 450 MT) in case the reservoir needs topping up after pushing back the piston
Check the CFMOTO 450 MT service manual for the exact torque values for the caliper bolts. Always confirm these against the manufacturer specification for your specific model year.
How do you replace the rear brake pads on a CFMOTO 450 MT?
Replacing the rear brake pads on the CFMOTO 450 MT involves removing the caliper, extracting the old pads, pushing back the piston, fitting the new pads, and reinstalling the caliper.
Follow these steps in order:
- Secure the motorcycle on a paddock stand or centre stand so the rear wheel is stable and accessible.
- Open the brake fluid reservoir on the rear master cylinder. Remove the cap and the rubber diaphragm inside. This relieves pressure and prevents overflow when you push the piston back later. Place a rag under the reservoir in case of any spill.
- Locate the rear caliper on the right side of the swingarm. Use the appropriate Allen key or socket to remove the caliper mounting bolts. Slide the caliper off the disc carefully. Do not let it hang by the brake hose.
- Remove the pad retaining pin or clip that holds the pads in place inside the caliper. This is usually a split pin or a bolt, depending on the caliper design.
- Slide out the old brake pads and inspect them. Note how they sit inside the caliper so you can mirror that orientation with the new pads.
- Clean the caliper with brake cleaner spray. Remove any rust, dust, or debris from the pad channels and piston face. Do not get brake cleaner on rubber seals if you can avoid it.
- Push the caliper piston back into its bore using a flat-bladed screwdriver or a dedicated piston tool. Apply steady, even pressure. This creates space for the thicker new pads. Watch the fluid reservoir to make sure it does not overflow.
- Apply a thin layer of copper grease to the back of the new pad backing plates and to the contact points in the caliper where the pads slide. Keep this compound away from the friction material entirely.
- Insert the new pads into the caliper in the correct orientation, then refit the retaining pin or clip securely.
- Slide the caliper back over the disc and refit the mounting bolts. Torque them to the manufacturer specification.
- Pump the rear brake pedal several times until firm resistance returns. This pushes the piston back out against the new pads.
- Check the fluid level in the rear master cylinder reservoir and top up if needed. Refit the diaphragm and cap.
- Test the brake at low speed in a safe area before riding normally.
What mistakes should you avoid when replacing motorcycle brake pads?
The most common mistakes when replacing motorcycle brake pads include contaminating the friction material, skipping the bedding-in process, and over-tightening or under-tightening caliper hardware. Each of these errors reduces braking effectiveness and can compromise safety.
Here are the key mistakes to avoid:
- Getting grease or oil on the pad friction surface or disc. Even a small amount of contamination drastically reduces braking power and is very difficult to fully remove. Always handle pads by the metal backing plate and wear clean gloves.
- Forgetting to push the piston back before fitting new pads. New pads are thicker, and the caliper will not fit over the disc unless the piston is fully retracted first.
- Not pumping the brake pedal before riding. If you skip this step, you will have no braking force at all when you first apply the rear brake, which is extremely dangerous.
- Ignoring the brake disc condition. Worn, scored, or warped discs reduce the effectiveness of even brand new pads. Always inspect the disc surface and measure its thickness against the minimum specification.
- Using the wrong pad compound for your riding style. Sintered pads suit off-road and wet conditions; organic pads suit lighter road use. Using the wrong type can lead to premature wear or inconsistent feel.
- Over-tightening caliper bolts without a torque wrench. This can distort the caliper or strip threads. Always use a torque wrench and follow the specified values.
How do you know if the rear brake pads are bedded in correctly?
The rear brake pads are bedded in correctly when braking feels progressive, consistent, and free from noise or vibration during normal use. Bedding in transfers a thin, even layer of friction material onto the brake disc surface, which is necessary for the pads to reach their full performance potential.
To bed in new rear brake pads properly on the CFMOTO 450 MT, follow this simple process:
- Ride at a moderate speed of around 30 to 40 km/h in a safe, traffic-free area.
- Apply the rear brake firmly but not aggressively to bring the bike down to around 10 km/h. Do not come to a complete stop.
- Accelerate back to 30 to 40 km/h and repeat the process eight to ten times.
- Allow the brakes to cool for several minutes before repeating the cycle once more.
Signs that bedding is going well include a progressively firmer and more responsive feel with each repetition. Signs that something may be wrong include persistent squealing after the first few stops, a burning smell that does not fade, or a pulsing sensation through the pedal. Pulsing often points to a warped disc rather than a pad issue.
Avoid heavy braking from high speed during the first 100 to 150 km after fitting new pads. This gives the friction material time to fully transfer onto the disc and reach optimal performance. After this initial period, the brakes should feel confident and consistent across all riding conditions.

Frequently Asked Questions
Can I replace just one rear brake pad, or do I need to replace both at the same time?
You should always replace both pads in a pair at the same time, even if only one appears significantly more worn. Fitting one new pad alongside a worn pad creates uneven clamping force across the disc, which can cause the bike to pull to one side under braking and accelerate disc wear. Pads are inexpensive relative to the safety risk of mismatched friction material, so replacing them as a set is always the right call.
How do I know which replacement brake pads are compatible with the CFMOTO 450 MT?
The safest approach is to cross-reference the OEM part number from your CFMOTO 450 MT service manual or the original pad itself, then match it against the aftermarket supplier’s compatibility chart. Many reputable brake pad manufacturers list compatible models directly on their product pages. If you are unsure, measure the pad dimensions — height, width, and thickness — and compare them against the replacement before purchasing. Buying from a supplier that specialises in adventure or dual-sport bikes reduces the risk of an incorrect fitment.
What should I do if my rear brake still feels spongy after fitting new pads and pumping the pedal?
A spongy pedal after a pad change usually points to air in the brake line rather than a pad issue. This can happen if the reservoir ran low during the job or if the system was disturbed. You will need to bleed the rear brake circuit to purge any trapped air, which involves attaching a bleed kit to the caliper bleed nipple and working fresh brake fluid through the system until the pedal feels firm and consistent. If bleeding does not resolve the issue, inspect the brake hose for damage and check that the master cylinder is functioning correctly.
Is it safe to ride the CFMOTO 450 MT off-road immediately after fitting new brake pads?
No — you should complete the bedding-in process on a safe, controlled surface before taking the bike off-road. Off-road riding often demands sudden, hard braking from unpredictable situations, and new pads that have not yet transferred a friction layer onto the disc will not deliver their full stopping power in those moments. Complete at least one full bedding-in cycle on tarmac and allow 100 to 150 km of varied riding before relying on the brakes in demanding off-road conditions.
How do I check whether my rear brake disc also needs replacing when I change the pads?
Use a vernier calliper or micrometer to measure the disc thickness at several points around its circumference and compare the readings against the minimum thickness specification in your CFMOTO 450 MT service manual. Also inspect the disc surface visually for deep scoring, heat discolouration, or cracks. A disc that has worn below the minimum specification or shows heavy scoring will compromise the performance of even brand new pads and should be replaced at the same time to avoid repeating the job prematurely.
Can sintered brake pads damage my rear brake disc on the CFMOTO 450 MT?
Sintered pads are harder-wearing than organic or semi-metallic pads, and on a disc that is already worn or close to its minimum thickness, they can accelerate surface wear more quickly than softer compounds. On a disc that is in good condition, sintered pads are perfectly safe and are actually the better choice for off-road, wet, or heavily loaded riding. The key is pairing the right pad compound with a disc that has adequate material remaining, and inspecting both components together at each service interval.
How often should I inspect the rear brake pads if I use the CFMOTO 450 MT for long-distance touring with luggage?
For loaded touring use, inspect the rear pads every 3,000 to 4,000 km rather than waiting for the standard 5,000 to 10,000 km interval. The additional weight of luggage significantly increases the braking load on the rear system, particularly on descents and during emergency stops. Building a quick visual check into your pre-ride routine on longer trips — looking through the caliper inspection window for remaining pad material — takes less than a minute and gives you early warning before wear becomes critical.
