Offering both reach adjust and SwingLink™ technology, the SRAM Guide RS Disc Brakes give you the confidence to ride faster and go bigger, knowing that you are in complete control of your bike. With 4-piston, dual diameter calipers and deadband-free brake levers, the Guide RS Disc Brakes are a sound choice for trail, all-mountain, and freeride riders alike.
Bleeding Edge™ – New bleed porting and fluid path make it easier to push fluid through the caliper for quick and easy bleeding, dedicated bleed adapter for the S4 caliper plugs into the bleed port and seals the system to minimize air contamination and fluid loss.
Expandable Bladder – SRAM's new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved back-pressure relief, which produces dependable braking power and consistency.
Heat Shield – The stainless steel heat shields breaks the thermal connection between the pad and caliper body, reducing caliper fluid temperature by about 20C even in the most extreme testing conditions.
Matchmaker™ and MMX Compatible – Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM® triggers, and various RockShox® controls, all with one tidy, light, clamp--a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker™ X integrates the RockShox®XLoc and is compatible with XX and X0 brakes. Standard Matchmaker™is also available and works with any split-clamp design and RockShox® PushLoc.
PiggyBack™ Reservoir – The brake fluid reservoir on SRAM’s latest lever design is optimized for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement—so you can switch your levers on the handlebar and run them moto without hassle.
Reach Adjust – Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.
SwingLink™ – Squeeze a new SRAM brake lever and you notice it immediately. Less deadband. More positive pad engagement. A new cam system requires less lever throw to push the pads toward the rotor. That's great but there's more to perfect braking performance than just power. You need control. Many brake systems minimize deadband -- but at the cost of modulation. SwingLink™ solves that with its special cam shape. When the pads contact the rotor, power is modulated, avoiding that "on/off" brake feel. It's the perfect balance of power and precision.
Timing Port Closure – A hydraulic brake’s timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.
