Description of SRAM Guide Ultimate Disc Brake - rear - Artic Grey Ano
FOLLOW THE LEADER.
The SRAM Guide brake family introduced a new standard for mountain bike brakes through rigorous design and testing, and has been proven at the highest levels of competition in the Enduro World Series and even with downhill World Cup wins. With its completely new, 4-piston S4 caliper, SwingLink lever cam, and carbon lever blade, the 360-gram Guide Ultimate stands alone as the new leader in its class. It has been engineered to be light and powerful, with superior heat management capabilities, which give you better, more consistent, more reliable braking. The new caliper design also incorporates a re-designed seal and aluminum piston interface for ease of setup and improved consistency, while Bleeding Edge technology makes bleeding Guide Ultimate a quick and easy task.

The all-new S4 Caliper features four machined and Moly-coated aluminum pistons for consistent rollback and easy set-up, improved heat management features and Bleeding Edge porting and adapter technology for easy bleeds.
Pistons diameter: two 14mm and two 16mm pistons for power and modulation.
New seals, gland geometry and piston coating for improved rollback, resulting in easier setup and improved consistency.
Heat Management: enlarged pad pocket, piston insulators and Heat Shield reduce operating temperature and minimize heat transfer to the caliper body.
Bleeding Edge: new bleeding adapter and porting for quick, mess-free bleeding.
GUIDE ULTIMATE HEAT MANAGEMENT
Aluminum heat shields breaks the thermal connection between the pad and caliper body.
Reduces caliper fluid temperature by about 20C even in the most extreme testing conditions.
Insulator integrated in the piston.
Phenolic pad interface: phenolic compound reduces heat transfer from the pads to the piston thus reducing fluid operating temperature.
Aluminum seal interface: consistent finish and reduced seal wear.
OPEN PAD POCKET
More air flow through the caliper to reduce heat.
Pad pocket is 2mm wider than the standard Guide caliper.
Pocket length is increased to expose full length of brake pads to air flow.
BLEEDING EDGE TECHNOLOGY
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.
