Advice:
* Depending on the rotors your vehicle already has on you might need to change the calliper mount brackets or you might just need to add some washers so the calliper will be mounted higher.* After having them installed for some time and the brake lever gets lose, there is a regulator on the lever and when tighten it the lever will become harder again. If it keeps lose even after regulating the lever or you see that you've lost the braking you used to have then these are the things to check:
1. Brake pads might have worn down
2. Hydraulic brake line is not 100% sealed and fluid is leaking
3. Air has been seeped into the hydraulic chamber.If it’s not just your brake pads that need be replaced then you might need to bleed the brake set. If you are comfortable enough to do it yourself you should look for video on Google. If not then we advise that you seek for professional help. Use mineral oil (NOT SYNTHETIC).
