Shimano MT200 Brake Pad Replacement with video

It’s not always low hydraulic fluid that lead to spongy brakes. Check your brake pads to see if they are worn and need to be replaced. 

After reinstalling the wheel, spin the wheel to see if the rotor is rubbing. 

To help center the rotor in the brake caliper, , squeeze the brake lever while using a 5 mm Allen key to loosen the brake caliper to the fork. Then tighten and let go of the lever, the adjustment should have helped center the rotor in the new brake pads you just installed. 

After this installation of the new pads , if your brakes are still spongy you might need to bleed or add brake fluid. 

AfterPartz disc brakes

I swapped out disc brakes that came with my bike. They always seemed to be needing to be bled. After about six or seven rides, the brake levers would need to be pulled pretty hard to activate the brakes. Here is a little step by step video showing the installation of the AfterPartz disc brakes. 
The AfterPartz Disc Brake System is a mineral oil based hydraulic system. This is an installation video showing the front brake, left hand brake lever and rotor and front wheel mechanism being installed. Follow the same steps for installing the rear system.  The cables for the rear brake, on the right side of the handlebar, is longer. The AfterPartz brake system comes with pre-bled hoses with both brake levers, pads and calipers ready to be installed. The brakes use Mineral Oil inside and not DOT fluid like many others on the market. Let me know what you think.
