Do you need a brake pad replacement?
Check for Brake Noise, If you hear a loud squeaking noise while applying the brakes then check the brake pad wear indicator below
If you no longer see the wear line then your pads are worn out and need replacement, else it needs Disc cleaning. Just take a clean rug and spray some brake cleaner spray on the rug and wipe the Disc thoroughly which will take out sand and other debris. And need to remove the pad and rubbed on Sandpaper for better braking.
But if you see scratching on DISC then the disc needs a replacement and won’t be fixed in the below steps.
Place your scooter on level ground and turn your handle on the Right side to begin the Caliper removal process. (If you own a paddock now is the time to put it on the stand)
Insert the 6mm Allen key/hex key in the 2 Bolts shown below and turn anti-clockwise, and start tapping the hammer on the key till it loosens up, Avoid slippage. Remove both bolts holding the calliper.
: Note the Bolts are torqued till the kingdom comes, so prepare yourself to be harassed.
After the calliper bolts are Removed slowly pull away from the Disc shown below
and remove the locking pin’s quarter pin using the nose plier shown below
Push the locking pin slowly back away and will release the brake pads from the calliper and Pull it out of it
Now inspect the wear - It should be even and straight. If it’s uneven or one side is worn more than the other side. you will need to service the calliper (Topic will be covered in Future)
Now look at the new pads and inspect if the pad material is not cut or damaged.
TIPS (optional) If your scooter is fairly new and washed at intervals avoid this
place one of the worn-out pads in the calliper and start pressing on the right side brake and left side brake till all 3 pistons touch the pad,
Spray it with brake cleaner around the pistons and dry it out (do not push them back with brake cleaner on it let it dry completely or, it might contaminate the HYDRAULIC brake fluid)
now using the old pad push back the pistons with the help of a screwdriver or piston pusher
Now the steps are in reverse
Put back the Pads as shown below
Refix the locking pin
Refix the quarter pin
Now Clean the disc with a rug and spray some brake cleaner and dry it out.
slide back the calliper unit on the disc shown below
Re-align the holes for the screws
Apply Loctite 243(a drop) on each of the calliper bolts and screw them. if you own a torque wrench (25lb. ft) use it or tighten it with the HEX - key as much as you can.
If you do something stupid like rounding off the bolts or applying brake cleaner on the pads (yes never apply brake cleaner on brake pads) it’s on you - my topic is a guide rather than a service manual or SOP. I do not take any responsibility for your action
