TOBWOLF MTB Hydraulic Disc Brake Set, Four-Piston Bike Brake Upgrade Kit
- 【Upgraded Four-Piston Drive】-- This mountain bike hydraulic disc brake features a four-piston dual-sided braking system with a CNC-machined aluminum alloy caliper body. Its synchronized bilateral piston clamping mechanism effectively prevents rotor warping. The quad-piston hydraulic system delivers powerful linear braking force, while optimized heat dissipation channels maintain consistent braking power during prolonged descents, achieving reliable stopping performance in all riding conditions.
- 【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.)
- 【Ceramic Brake Pads】-- The innovative self-adjusting brake pad retraction system combines with tool-free pad replacement design, working in tandem with upgraded ceramic brake pads and non-corrosive mineral hydraulic oil to ensure exceptional heat-resistant performance.
- 【Stainless Steel 6-Bolt Disc Rotors】-- Ultra-light rotors that shed weight and shred trail, while still achieving superior braking power and modulation. With massive vent holes throughout the spider, and drilled holes through your contact patch to help both with heat vetting and weight shaving.
- 【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.
