How to Change Brake Pads on a 2013 Honda CRF450R
Shop parts for a 2013 Honda CRF450R Dirt Bike.Quick overview of the braking system
Most modern dirt bikes including the 2013 Honda CRF450R use hydraulic disc brakes. The system consists of the brake lever or pedal, master cylinder, hydraulic brake line, brake caliper, brake pads, and a steel rotor. When you pull the lever or press the pedal, hydraulic pressure forces the caliper pistons to push the brake pads against the rotor, converting kinetic energy to heat and slowing the bike.
When to replace brake pads & why it matters
Brake pads wear with use, and proper braking performance is essential for safety and control in motocross, trail, enduro or dual-sport riding. Replace pads when you experience any of the following:
- Reduced braking power or longer stopping distances
- Squealing, squeaking, or grinding noises
- Excessive brake lever or pedal travel before engagement
- Visible pad material worn thin — backing plate exposed or less than a few millimeters of friction material
- Heat discoloration on the rotor or glazing on pad faces
Inspect pads after muddy rides or long sessions; abrasive grit accelerates wear.
Tools & parts you'll need
- Replacement brake pads compatible with 2013 Honda CRF450R
- Basic metric socket set, open-end wrenches
- Needle-nose pliers or snap-ring pliers (for retaining clips)
- Flat screwdriver or punch (to push retaining pin if needed)
- Clean rags, isopropyl alcohol or brake cleaner
- Shop stand or secure center stand
- Small C-clamp or piston compressor tool (optional)
Step-by-step – change the pads
- Prepare the bike and workspace. Park the CRF450R on a stable stand with the suspension extended. Work in a clean, well-lit area and gather your tools.
- Decide whether to remove the wheel. On many motocross-style setups like the CRF450R, you can access the front or rear caliper without fully removing the wheel. If you prefer more room or the caliper blocks access to the retaining pin, remove the wheel first by loosening axle nuts and pulling the axle.
- Remove the retaining pin or clip. Locate the pad retaining pin or cotter clip on the caliper. Use pliers or a screwdriver to remove the clip, then slide out the pin. Keep hardware in a small container so it won't be lost.
- Slide the old pads out. Pull the pads straight out of the caliper bracket. Note their orientation and any shims or pad springs; you'll reinstall the new pads the same way.
- Inspect rotor & caliper. Check the rotor for deep scoring, cracks, or excessive runout. Look inside the caliper for debris, pad chunks, or signs of leaking brake fluid. Clean with brake cleaner and a rag if needed.
- Compress the caliper piston(s). With the old pads removed, push the piston(s) back into the caliper slowly using a C-clamp or a flat block of wood and a large screwdriver. This creates space for the new, thicker pads. If the piston is stiff, work it in small increments to avoid damaging seals.
- Install the new pads. Place any shims or anti-rattle springs onto the pads, then slide the new pads into the caliper in the same orientation as the originals. Ensure the pad faces contact the piston and the outer pad seats properly in the bracket.
- Reinstall retaining hardware and wheel. Reinsert the retaining pin and secure the clip. If you removed the wheel, reinstall it, torque axle hardware to the proper snugness, and re-seat the caliper over the rotor.
- Restore hydraulic pressure. Before riding, sit on the bike and pump the brake lever or press the pedal several times until a firm feel returns — this moves the pads into contact with the rotor and restores normal lever travel.
- Final check. Spin the wheel to confirm no binding and that the caliper is centered. Re-check hardware tightness after a short test ride.
Helpful inspection tips while you're in there
- Measure rotor thickness against the manufacturer's minimum if you have the spec; otherwise, replace if noticeably thinned or grooved.
- Look for fluid leaks at the caliper seals or around the banjo bolt & crush washers. Any sign of leaking warrants attention.
- Ensure the caliper slides freely on its pins or mounting surface; seized slides cause uneven pad wear.
- Clean mud, grit and old grease from the caliper bracket and pad pockets to prevent sticking.
- Verify retaining pins and clips are fully seated and not bent or corroded.
Bedding in your new pads
Bedding properly mates the new pads to the rotor surface and maximizes stopping power. Perform 8–12 controlled stops from moderate speed (walk up to 25 mph) to a near stop, allowing the brakes to cool between repeated heavy stops. Avoid full stops from high speed on the first ride. After bedding, re-check lever feel and hardware torque.
Model notes for the 2013 Honda CRF450R
The 2013 Honda CRF450R is a high-displacement motocross machine with braking demands typical of 450cc competition bikes — powerful engine, aggressive deceleration, and frequent heavy braking on jumps and berms. Most CRF450R models use conventional hydraulic disc brakes; if you've seen changes across generations, those are usually rotor size or caliper detail updates rather than fundamental system differences. This guide focuses on common garage-level maintenance for that motocross-style setup.
