233618 O Ring Rebuild Kit for All Gma 4 Piston Calipers

This GMA O-ring rebuild kit is tailored for four-piston calipers, providing the internal seals necessary to prevent fluid bypass and external leaks. The kit includes the specific elastomer rings required to seal the piston bores and the caliper body halves. GMA is a trusted manufacturer in the V-twin market, and their braking systems require precise replacement seals to maintain the firm, predictable stopping power they are known for. Over time, heat and chemical exposure can degrade original seals; this kit offers a direct solution for restoring performance. Sold as a set, it contains all the rubber components needed to service one four-piston caliper assembly.
