Brake lever piston compatible with SRAM Guide and DB5 models — a direct, durable replacement that restores reliable braking performance without changing lever feel. Key benefits Multi-model compatibility: Fits a range of SRAM Guide and DB5 brake lever assemblies so you can service multiple bikes with the same part. Lightweight, robust construction: Machined from aluminum alloy to provide a low weight while remaining strong enough for regular use on trails or roads. Temperature-resistant performance: Designed to maintain function under high temperatures encountered during long descents or heavy braking, reducing the risk of piston sticking or loss of performance. Complete repair ready: Ships with two sealing rings included, giving you what you need to rebuild the piston side of your brake system. Why you need it A worn or damaged piston can cause spongy lever feel, reduced braking power, or leaking. Replacing the piston with this aluminum alloy unit restores consistent pad actuation and lever response. The included seals simplify installation and reduce the number of parts you must source separately. Practical applications / use scenarios Mountain biking: Replace a worn piston after aggressive trail use to recover firm, predictable braking on technical descents. Commuting/road use: Maintain consistent brake feel under frequent stop-and-go conditions and in variable temperatures. Workshop repairs: Keep a spare piston and seals on hand for routine brake maintenance or when rebuilding Guide and DB5 brake assemblies. Product details Function: Brake lever piston for SRAM Guide and DB5 models Material: Aluminum alloy Performance: High temperature resistance, designed for regular trail and road use Included: Two sealing rings Fits Guide and DB5 systems as specified; use with compatible brake assemblies and follow manufacturer service procedures for installation and bleeding.
