Brake line hose will greatly improve your braking effect. Green Motorcycle Universal M10 0°-90° Stainless Steel Clutch Oil Pipe Hydraulic Brake Hose 10cm-500cm Motorcycle brake lines connect the brake pump and brake calipers (or brake drums), forming a closed brake fluid transmission channel. The brake lines connect the brake pump and the brake calipers. When the rider operates the brake lever or pedal, the brake fluid in the brake pump is pressurized. This pressure is transmitted through the brake lines to the brake calipers, pushing the pistons to force the brake pads into close contact with the brake disc or brake drum, generating friction and thus slowing the motorcycle down or stopping. Avoid Collisions and Compression: Avoid collisions with other objects while riding to prevent brake line rupture or leaks.
