TaoTao Quantum Disk Brake Issues
Hello all, Here is the rundown of my Scooter
TaoTao 150cc Quantum/Titan Purchased brand new March 2021 Got it off Amazon Shipped in a crate to my door. Right now 340 miles on it I had to assemble few parts on it including the front rim/tire Ok here is the issue with the front brake which is a disk brake setup. When the scooter is pushed forward there is a rattle coming from the front caliper. When the Scooter is traveling down the road there is a rattle in the front caliper. Now I have taking the caliper off. It has two allen head bolt/screws on the back side you have to pull to get the pads out. The Pads look brand new and no defects to them. There is a upside down like triangle pressure spring/metal thingy in that looks perfect and I have inserted it back proper. I have assembled it all back and tightened down the two Caliper Mounting bolts and they are very tight. For the life of me. I can't figure out where that rattle is coming from. The Brakes work fine.. it is just that rattle sound that has me puzzled. I have taken that caliper off like 8 times now to try and solve it. Unless the Caliper is just plain out defective. |
Did you check the brake rotor for runout? It could be hitting the pads on a high spot in the rotor. Also look for other parts in the front that could be loose. It may appear to be the caliper but could be something like a loose fender or speedometer cable bracket.

You don't need a dial indicator. Just rest a pencil or screwdriver on the caliper or fork leg and put the point on or near the rotor and rotate the wheel. If you see different space between the pointer as it spins you'll know the rotor is slightly warped. I used to true wheels in the field on bicycles by using the distance between the brake pads as a guide.
