Tools and parts: the new brake rotor, T25 Torx wrench, 19mm wrench, diagonal pliers

 

Step:

Front wheel:

1. Remove the battery to prevent the battery turn on during replacement.

2. Remove the front wheel, and put the front fork on the sponge.(front wheel installation guide)

3. Install the new brake rotor

a. Put the front wheel flat with foam padding at the bottom so that the hub axle does not touch the ground.

b. Use T25 Torx wrench to unscrew the bolts of the disc brake rotor counterclockwise in a diagonal order. (In order to prevent the disc brake rotor from being unevenly stressed and causing the bolts to jam).

c. Remove the disc brake rotor and rotor bolts, put them aside.

d. Put the disc brake rotor with the literal side up and insert it into the upper hub alxe (hands cannot touch the red position in the picture), and rotate the disc brake rotor to make the mounting holes align with the mounting holes at the hub.

e. Put the disc brake rotor with the literal side up and insert it into the upper hub alxe (hands cannot touch the red position in the picture), and rotate the disc brake rotor to make the mounting holes align with the mounting holes at the hub.

4. reinstall the front wheel.(front wheel installation guide)

5. Reinstall the battery.

 Inspection:

1. Check that the front wheel is installed tightly.

2. Check that the brake rotor is in the middle of the two brake pads, and check the function of the brake.

3. Check whether the front wheel can work normally.

 

Rear wheel:

1. Remove the battery to prevent the battery turn on during replacement.

2. Remove the rear wheel, and put the frame on the bracket.(rear wheel installation guide)

3. Install the new brake rotor. Same as the installation and removal steps of the front wheel brake rotor.

a. Put the front wheel flat with foam padding at the bottom so that the hub axle does not touch the ground.

b. Use T25 Torx wrench to unscrew the bolts of the disc brake rotor counterclockwise in a diagonal order. (In order to prevent the disc brake rotor from being unevenly stressed and causing the bolts to jam).

c. Remove the disc brake rotor and rotor bolts, put them aside.

d. Put the disc brake rotor with the literal side up and insert it into the upper hub alxe (hands cannot touch the disc brake rotor plane), and rotate the disc brake rotor to make the mounting holes align with the mounting holes at the hub.

e. Then use T25 Torx wrench to tighten the disc brake rotor bolts in diagonal order (to prevent uneven installation of the diac brake rotor).

4. reinstall the front wheel.(front wheel installation guide)

5. Reinstall the battery.

Inspection:

1. Check that the rear wheel is installed tightly.
