Honda's 2006 CRF230F is equipped with a disc-style brake on the front wheel and an older-style drum brake on the rear. Since today's riders are not familiar with drum brakes, replacing worn brake shoes can be difficult. Luckily, the job is much easier than it appears, providing that you have the knowledge and tools to remove the rear wheel. Once the wheel is off, switching out the brake shoes is a breeze.
Things You'll Need
- 16 mm socket
- Long-handled socket wrench
- Motorcycle stand
- 10 mm wrench
- Brake shoes (Honda part #06430-GBJ-J10)
- Medium-grit sandpaper
- Brake-cleaning spray
Loosen the rear axle's lock nut using a 16 mm socket and a long-handled socket wrench. Do not remove the lock nut at this time. Place the motorcycle on a stand or lift to raise the rear wheel off the ground.
Unscrew the adjuster nut from the brake rod using a 10 mm wrench. Depress the rear brake pedal to disengage the brake rod from the brake arm. Rotate the chain adjusters on both sides of the rear wheel forward to loosen the drive chain. Pull the chain off the rear sprocket.
Remove the rear axle lock nut and pull away the chain adjuster from the right side of the rear swing arm. Pull the rear axle out from the left side of the rear wheel and remove the left chain adjuster. Lower the rear wheel to the ground and remove the spacers from the wheel.
Lay the wheel on its side with the brake drum facing upwards. Pull the brake drum off the wheel and lay it face down to expose the brake shoes. Remove the brake shoes. Disconnect the brake-shoe springs and discard the old brake shoes. Connect the springs to the new brake shoes.
Sand the inner surface of the brake drum with a medium-grit sandpaper to remove any burrs or glazing that may have formed on the drum. Spray the inner surface with an aerosol brake cleaner to remove brake dust and dirt. Apply a coating of grease to the brake drum's cam and brake-arm pivot.
Insert the brake shoes into the drum and install it onto the rear wheel. Replace the rear wheel's spacers and lift the wheel into the motorcycle's rear swing arm. Place the left chain adjuster against the rear swing arm and insert the rear axle. Place the right chain adjuster onto the rear swing arm and loosely screw the rear axle lock nut into place. Insert the brake rod into the drum's brake arm and tighten the brake-adjuster nut. Slip the drive chain over the rear sprocket. Rotate the chain adjusters back to tighten the chain.
Depress the rear brake pedal to engage the rear brakes, aligning the brake shoes with the rear wheel. Hold the rear brake pedal in place and tighten the rear-axle lock nut completely. Release the brake pedal and adjust the rear brake as needed.
Tips & Warnings
- Brake dust can cause eye, skin and lung irritations. Wear protective eye wear, gloves and a mask to prevent injuries.
