SRAM Guide R S4 Update 2 810x540


When they were introduced two years ago, SRAM’s Guide brakes carried over the calipers from their predecessors. Last year SRAM introduced a new caliper on their top-of-the-line Guide Ultimate brakes, that is now rolling out to the rest of the product lineup. All the news directly from SRAM:

All Guide brakes benefit from the upgrade and get the new S4 caliper.

The S4 caliper, born on Guide Ultimate, now moves to the complete Guide range. While retaining the on-trail characteristics of Guide, the S4 caliper will add the following features to Guide RSC, RS and R:

  • Heat Management: Enlarged pad pocket, insulated pistons, and Heat Shield reduce operating temperature and minimize heat transfer to the caliper body.
  • Rollback Consistency: New gland geometry and piston design
  • 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 plugs into the bleed port on S4 calipers. It seals the system to minimize air contamination and fluid loss.
The new S4 Calipers from the Guide Ultimate now roll out to the rest of the lineup.

Moreover, the Guide brakes get an updated reach adjust with new detent design, more positive feel and smaller nub. The backward compatible reach adjust is said to eliminate creep.
