BIKE TOTAL SOLUTION Handle Lever Bike Tool Hydraulic Bleed Kit Hydraulic Brake Caliper Bike Rotor Bike Saddle Bike Disc Brake Kit Bike Seat Posts V Brake Handle Lever Disc Brake Caliper Review: You get what you pay for - The larger the rotors, the greater the braking power. The title says 160 mm rotors. The print below says 140 mm rotors. You get 140 mm rotors, which are adequate for a small, light person. Not so much for a larger adult male. Very cheap construction. The mounting bolts are a very cheap metal that shows wear after normal installation. The plastic brake pad adjustment knobs are stretched too big for the Allen wrench after normal installation. More practical installation instructions. 1. Tighten the brake pad adjustment until there is just a small amount of movement when you squeeze the brake lever. 2. Tighten the caliper mounting bolts. Not too tight or they will strip! 3. Loosen the brake pad adjustment until the wheel just turns freely. 4. Tighten the brake lever adjustment if needed.
