Disc brake caliper for gravel Shimano GRX, model RX400

GRX Brake Systems: One of the gravel rider's main concerns is having enough braking force to control speed on steep downgrades or those that appear suddenly. This is why, at the top of the GRX range, one of the variants of the RX800 series levers (ST-RX815) offers Servo Wave technology from Shimano mountain brakes. It will provide us with a more powerful braking sensation and greater modulation for more aggressive driving. If you prefer the RX810 option without Servo Wave or the RX600 and RX400 series levers, they will still provide enough stopping power on a par with Ultegra, 105 or Tiagra discs, respectively.

Another option to consider within the braking options is the BL-RX812-L/R hydraulic brake sub-lever that is connected to the main braking hose that goes to both the rear and front brake calipers. These sub levers are designed to mount on the bars and close to the stem, making them an option when you have your hands high on the bars.

The brake calipers of the GRX BR-RX810/400 range have the same design as Shimano's flatmount road brake calipers from which they inherit high performance and features such as One-Way one-way bleeding and heat dissipating technologies. ICE TECHNOLOGIES heat in the pads and discs to offer efficient cooling that allows stable performance for longer.

Technologies:

• ICE Technologies
  • The loss of braking efficiency due to overheating, which can occur in the brake disc and pad when braking on long descents for example, has a negative impact on braking performance. SHIMANO has adopted the ICE TECHNOLOGIES brake disc and ICE TECHNOLOGIES pad to realize cooling technology that provides reliable performance. The coated brake disc blade, which has a 3-layer sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance and allows the surface temperature to go from 400°C to 300°C. Also, a radiation fin has been adopted for the pickup. In addition, the coated brake disc blade and radiator fin offer long pad life, less noise, less loss of braking efficiency due to overheating and light weight.
• ONE WAY BLEEDING
  • 'ONE WAY BLEEDING' has been developed for a quick and easy prevention of the presence of air in our hydraulic system. We have streamlined the path of the oil in the system to avoid air bubbles in the system. One-way oil path, plus a funnel tool with mineral oil, provides an easy and clean bleeding system.

Characteristics:

• Excellent heat dissipation
• flat support
• Convenient access to tools
• Easy change of wheels
• Clean and simple purge system
• Don't hesitate to tackle rough surfaces.
• Easy installation and maintenance
• Model: BR-RX400-F
• Series: SHIMANO GRX 11-speed
