The SRAM Disc Brake Piston Massage Spacer 3.7mm is a purpose-built hydraulic disc brake service tool designed to improve brake setup, piston alignment and lever feel during maintenance. Compatible with all SRAM disc brake calipers except Monoblock calipers, this spacer is an essential workshop accessory for mechanics and home bike maintenance.
Used during a brake piston massage procedure, the spacer allows caliper pistons to be safely advanced fully out and reset evenly, helping restore smooth piston movement and consistent braking performance. It replaces the common practice of stacking two brake rotors, providing a safer, more precise and professional solution when servicing SRAM hydraulic disc brakes.
Ideal for bleeding, piston lubrication and brake performance tuning, the SRAM piston massage spacer helps achieve improved pad clearance, better lever feel and more consistent braking response across MTB, road, gravel and e-bike applications.
