•【Important NOTE】-- This set works on the principle of Left Front and Right Rear, which means the left lever controls front wheel brake, while the right lever controls rear wheel brake. The position of front and rear brake operation may vary due to different people or regions. You may switch the brake cable based on your actual needs. (Using a wrentch and a plier to disassemble the brake cable and swap the sides. There might be small amount of oil leakage, but it doesn't affect the usage.)
•【Installation Instructions】-- Make sure the calipers and pads correctly fitted to the hub and aligned with the disc. Adjust the clearance and fine tune the brake adjustment screws to ensure good braking without clicking. Exhaust the hydraulic disc brake system to maintain optimum performance. Pull the brake handle to test if the brakes are contacting the disc to make sure the braking effect is normal. (Kindly contact us to send you the user manual. Also check the video on this detail page.)
•【Upgraded Ceramic Brake Pads】-- The ceramic brake pads will not damage the disc, and further improves the braking effect. Please remove the caliper protection sheet before installation.
