Vado SL Brake Pads and Rotors
I'm writing this for the future reference, so anybody who wants to replace their brake pads on a Vado SL can use the Search function.
Brake pads for Tektro HD-R510 or HD-R290 Hydraulic Disk Brakes
I chose the SwissStop brake pads.
Brake Rotors
Any 160 mm diameter, Centerlock mounted rotor would do. (There will be a word of warning, though).
The Centerlock rotor on Vado SL is removed by inserting a standard cassette wrench and simply unscrewing the lock-ring.
Please do not damage or lose the lockring!
When you are buying the new Centerlock rotor, pay attention to buy the one with the "lock-ring with internal serrations" (I bought one with external serrations). The externally grooved lock-ring requires a wrench you probably do not own, and that setup is used for 15 mm thru-axles. The internally grooved lock-ring is for 12 mm axles.
Nothing went wrong in my case as I simply re-used the old lock-ring and easily tightened it with the cassette wrench.
Note: The only reason to replace the rotor in my case was the fact the rotor had got bent (I can bet it happened on a crash
) then it was straightened by a mechanic and then I think it became somewhat warped
