Raymond's brake O-ring seals a hydraulic joint inside the brake system, holding pressure so the brake actuates firmly instead of losing fluid past the seal. An O-ring hardens, flattens, and loses its seal with heat and age, and a weeping brake seal shows up as a soft brake response, slow actuation, or visible fluid loss at the joint.
Raymond's brake O-ring seals a hydraulic joint inside the brake system, holding pressure so the brake actuates firmly instead of losing fluid past the seal. An O-ring hardens, flattens, and loses its seal with heat and age, and a weeping brake seal shows up as a soft response, slow actuation, or visible fluid loss. Replacing it during a brake service restores a tight hydraulic seal. Match the O-ring's inside diameter and cross-section to the one being replaced, and use a compound rated for brake fluid, since an O-ring of the wrong size or material will not hold pressure.
